No processing for event 'report_RHTSupport' is defined

[Yasha Karant]

A MATE applet vi EPEL crashed.  An automatic bug reporting tool 
activated without my intervention (prompted for my sudo login).  I went 
through all of the screens that appeared;it
seemed to want to submit the issue to RedHat, not EPEL nor SL/CentOS.  I 
answered all of the prompts, and in the end, the automatic tool failed 
with a diagnostic:


No processing for event 'report_RHTSupport' is defined

How does one configure this or is this an artifact from the original 
RHEL source that was not modified (unlike the various logos, splash 
screens, etc.) and somehow still is configured for a RedHat licensed 
(for fee?) support product?  Can this be configured to point to either 
the add-on reposiity (e.g., EPEL, ELRepo, etc.) or to either SL or 
CentOS?  If there are any on this list from CERN or in a CERN supported 
collaboration, I know that CERN has an internal support mechanism that 
is *NOT* made available to SL users (even when Fermilab and CERN were 
jointly mentioned on SL); as a matter of information, does the CERN 
"CentOS" team have an internal CERN configuration whereby these reports 
go to a CERN network location (obviously not available to those of us 
not part of a CERN collaboration)?

Thanks for working on this, Russ.  While reinventing the wheel is 
frowned upon most of the time, there are settings where reinventing 
wheels should be encouraged, particularly the educational setting. 
Sometimes it is worthwhile to do some calculations by hand or by slide 
rule, then go back to the calculators and spreadsheets; the act of 
reinventing enhances the understanding of why things are done the way 
that they are done. You better appreciate koji if you build your own 
mini-beehive.


For most of us, though, it's just a time sink.  Yasha is in a 
different environment than most of us.
I may be in a university environment, but we do not waste time 
reinventing the wheel for research or research support activities -- and 
neither does any other viable research group.  However, it was my 
understanding that the EPEL or other similar automata are not readily 
available -- for deploying production code through porting there is no 
reason not to use an existing "automaton" that can resolve dependencies 
(I recall a correspondent referring to these sorts of things as 
:dependency hell") from whatever source code repositories as required 
and ultimately build a working executable application.   At the moment, 
my group does not have a porting machine that we could dedicate to this 
sort of problem.  This is not an issue of "critical thinking", etc., but 
rather pure technological implementation.  However, the development of 
that technology does require a variety of "critical thinking" 
activities.  I definitely do not want to get into the repo "business" at 
this time -- we do not have the resources that we can spare from other 
activities, and are not likely to get the necessary external funding to 
become a repo development "house".  But -- I would very much like a 
working SL7 binary executable of a reasonably current Abiword.

RPMs are required again for SL7. As it appears that there are business 
restrictions that prevent Owlriver from offering any such binaries,
I hope that someone else may -- or EPEL will come through in short 
order. (I was under the impression that a business could offer executable
software without cost for download provided the usual "disclaim all" was 
part of the download and use "license".)   abiword  is available for

Are there other files that are needed other than those provided in the

the Red Hat subscriber repos are not readily available to the 
non-paying, only CentOS repos under the Red Hat "umbrella".)


By the way, as a university (not a business), are we allowed to 
redistribute binary RPMS made from the above .src.rpm files with the
usual acknowledgement (thanking you and your firm, but no guarantee that 
anything works and no guarantee that the binaries will not
"destroy" any system upon which these are installed)?  If we do build

some time considering 'policy' as to releasing sources vs.
binaries, and concluded that there were obligations to 'stand
behind' binaries, which did not arise with a simple set of
related sources.  Unless one is a commercial customer of Owl
River, binaries are not available ( contrariwise, all binaries
installed at any customer are backed by availability of
sources at the site previously indicated, thus satisfying GPL
and related 'source availability' obligations )

Although EPEL "should", being like CentOS these days a more-or-less

You indicated that you are willing to release the SRPMs that have 
already been ported (both for source

code and dependencies) to SL 7 and that upon using a command syntax like:

rpmbuild --rebuild /tmp/mypackage-1.0.0-1.src.rpm

where  .src.rpm is the same as .srpm (as I recall).

will result in a (set) of binary RPM files that will install application 
"binaries" that will execute under SL7.  Any dependencies (e.g., other 
development
packages, not just header file RPMs, but ".so" file RPMs) will be 
revealed by the rpmbuild step and can be "fixed" through
yum install foobar (where foobar is the dependency) from either SL, 
EPEL, or ElRepo, not RPMs for which one has the
merry chase on the web (sometimes resulting in other incompatibilities 
or real vulnerabilities).  I am not trying to be overly specific here, 
but my
group (as I am certain have others on this list) has more than once had 
to chase down RPM dependencies (e.g., libraries) that only were made
at one laboratory somewhere -- and never made it into the "mainstream" 
EL repos (say ported from some other Linux family).


Thanks for any clarification.

Thanks Bill!

You are absolutely correct. Switched back to GDM and the MATE

Before, I looked everywhere for a desktop selection at login, but 
never thought to look again after selecting my username. I don't 
recall having to select MATE from a login list after installing under

I have not investigated the actual "name" of the 
application/applet/whatever that provides the default login screen to a 
SL 7 GUI environment (by "default", I mean that after an installation 
using the GUI installer for SL 7, this is the screen that appears for 
login).  Unlike on OpenSUSE, what ever this is works fine with MATE as 
installed from the EPEL repo.


There is a small "gear" icon on screen.  Using that icon, one gets a 
list (e.g., Gnome, KDE, ... ) upon which is listed MATE after the MATE 
installation.  No "fiddling" was required to change the default login 
GUI application (unlike my experience with OpenSUSE under which I did 
need to change the equivalent application to one that "supported" the 
OpenSUSE port of  MATE.


For those who do not like either the current Gnome or KDE (both of which 
seem to have the aroma of MS Win 8 desktop or MacOS X desktop, perhaps 
with a bit of the Android desktop as well), are there fully provisioned 
alternatives to MATE?  The previous Gnome 2 GUI, as with MATE, seems to 
have all of the functionality that a professional (not "thats 
entertainment") user needs.  As MATE is a "fork" of Gnome 2 updated to 
run under later release distros for which Gnome 2 is not available (and 
not being developed/ported by the Gnome "team"), it more or less is 
Gnome 2 (with icon and possibly name changes, just as SL has icon 
changes from RHEL in so far as such icons carry the Red Hat "brand" -- 
thus there is "eye of mate" rather than "eye of gnome", etc.).

MATE on SL 7

[Yasha Karant]

It appears that the software package GUI installer, gpk-application, 
does not have what is needed for an install of MATE
under SL.  (One evidently does not need MATE for SL 6 as Gnome 2 is part 
of the stock SL 6 distribution).  During the base install of SL 7,
I always install both whatever Gnome and KDE GUIs are supplied; thus the 
comment below about X windows is not relevant for my use.
I do this on servers as well as workstations so that graphical machine 
"workload" display and analysis tools are available in addition to the
scrolling text tools.  (Sometimes a visualisation provides insight that 
a table or text does not.)


From:

http://wiki.mate-desktop.org/download

Red Hat Enterprise Linux 7

MATE is available through the Extra Packages for Enterprise Linux (EPEL) 
repository, maintained by the Fedora Project. This should work on CentOS 
7 as well, and any other compatible derivatives.


After you install the epel-release-7*.rpm package to add the EPEL 
repository to Yum, you can install MATE with the following command:


yum groupinstall mate-desktop
If you install this on a minimal system without an existing GUI 
configured (such as a GNOME or KDE desktop), you might want to install 
the X Window System group as well for local graphical logins:


yum groupinstall "X Window System"
you may also want to change the default systemd target to graphical:

systemctl set-default graphical.target

End quote.  Note that unlike other entries in this URL document, the 
actual release (version) of MATE is not given (presumably because the 
document maintainers do not have the time or perhaps do
not get information from the EPEL "team",  Also, unlike the entry for 
Debian that states:

Debian

MATE 1.8.1 is currently packaged for Debian 8 (jessie). MATE 1.12 is 
also available on Debian testing (“Stretch”) and unstable (“Sid”).


(If sudo is unavailable on your system, simply omit it and use a root 
shell)

First make sure your package list is up-to-date by running:

sudo apt-get update
To install MATE, choose one of the apt-get options below.

This will install the base packages required for a minimal MATE desktop
sudo apt-get install mate-desktop-environment-core
This will install the complete MATE desktop
sudo apt-get install mate-desktop-environment
This will install the complete MATE desktop including a few extras
sudo apt-get install mate-desktop-environment-extras

End quote

There is no explanation of just which components are automagically 
loaded through the use of the RHEL 7 instructions; that is,
there is no explicit equivalent of:   This will install the complete 
MATE desktop including a few extras

sudo apt-get install mate-desktop-environment-extras

i am not certain what are in the "extras"; I do know that after I got 
MATE up and running on my wife's SL7.2 laptop, I had to hunt for the 
other RPMs I needed
to get MATE GUI displays of what she expected (and I also use on  my 
MATE desktop).  I am referring to items for the MATE menu and items for 
a MATE panel (e.g.,

Virtual Box MS Win 7 guest no NAT issue now understood

[Yasha Karant]

I have now resolved the cause of the lack of NAT Internet connection on 
a Virtual Box MS Win 7 guest.  After I installed SL 7.2 on my wife's new 
laptop,
I restored (via a cp from an external USB hard drive that held all of 
the files that were not SL installed, including all of the Virtual Box 
guest files) the Virtual Box
guest files from her previous laptop to the new machine.  I installed 
the Virtual Box EL7 RPM, configured VirtualBox to recognize the restored 
guest files, and the
NAT network functioned over the 802.11 WNIC controlled by SL 7 Network 
Manager -- everything worked (indeed, any statements that NAT would not 
work with 802.11 in
"new" kernels were indeed red herrings).  When I then restored her guest 
machine (MS Win 7 Pro as well) to my SL 7 laptop, again, NAT worked.  
Thus, I have determined that
(somehow) the MS Win device NIC device driver that Virtual Box uses to 
connect to the NIC supplied by Virtual Box to the MS Win 7 guest was 
"broken".


I have created a second virtual disk and have attached this to the MS 
Win 7 system that "works", and am in the process of doing a MS Win 7 
backup (not a Linux backup) to this additional
virtual disk that the MS Win 7 guest "sees" now as drive E: .  I do not 
know MS Win very well at all, using it as an appliance, and real source 
code and OS architectural details are not readily available (several of 
my students who worked in MS Win "shops" have access to material 
licensed only to such "shops", not to persons such as myself, and even 
these have large limitations according to my students.)


 I know that I may remove said virtual disk from the working MS Win guest
and attach it, via Virtual Box, to the non-working MS Win guest.  I am 
not asking for a response to the SL list, but if anyone on this list 
knows how I can use this "backup" virtual hard drive to restore
just the MS Win systems files (specifically, just this NIC driver and 
whatever associated MS Win 7 systems files it "needs"), I would greatly 
appreciate off-list (via my private email, ykar...@gmail.com
if possible) as to what to do -- or a URL with the necessary 
instructions.  Any help greatly would be appreciated.


All of the guests in question are MS Win 7 Pro SP 1, and all have the 
necessary MS Win
license.  If at all possible, I do *NOT* want to "smash" the 
applications installed into the MS Win guest when I restore just the MS 
Win OS files.

He says that ElRepo DO read the list, which you then confirm, so
why is that a blunder?

I think you owe him an apology, unless I have seriously

OK ... I see that there was some misunderstanding ...

Let's make peace here, shall we?

Regarding contacting EPEL maintainers, I see the following description 
in EPEL's FAQ:


"You can find help or discuss issues on the epel-devel mailing list or 
IRC channel #epel on Freenode. Report issues against EPEL via bugzilla"
( 
https://fedoraproject.org/wiki/EPEL/FAQ#Where_can_I_find_help_or_report_issues.3F 
)


Just checked the epel-devel mailing list. It does not seem to be 
actively used at this moment. So, I would suggest use of 
bugzilla.redhat.com <http://bugzilla.redhat.com> is the way to go.


Regarding ELRepo, while we (ELRepo team members) are reading this SL 
list, it is best to use ELRepo's mailing list to address any issue or 
ask questions ( http://lists.elrepo.org/mailman/listinfo/elrepo ) 
rather than here. In fact, I encourage everyone who uses ELRepo's 
packages to subscribe to the list.


Akemi
Although you are correct that you seriously did misunderstand what I 
posted, what you have posted confirms what I have observed after my 
posting on EPEL to the SL list:  contacting anyone who knows EPEL and 
getting a meaningful response is about the same as I experienced with 
SuSE support (non-existent except for SLES and then only to "large" 
"corporate" customers).  The comment I received from a person who gets 
the EPEL Red Hat Bugzilla "reports" was this:


I don't have much to do with MATE directly (I'm mostly a package sponsor for 
some of the folks more directly involved).

So, I'd recommend sticking relevant details in bugzilla

End quote.

Note that, unlike ELRepo folks with whom one can communicate via the SL list (persons who even are 
willing to identify themselves, and not "hide" behind some Bugzilla-like interface), EPEL 
seems much more unwilling to discuss matters.  Has an EPEL "maintainer" ever (recently) 
posted/replied to the SL liist?

I fully understand that the ELRepo folks are (presumably) volunteers, and thus may have 
little real free time to address such issues; hence, one should not pester them, 
particularly from typical enthusiast "users".  I suspect that EPEL persons in 
part may, as with CentOS, now be paid by Red Hat, but I do not know this for a fact.  I 
have had few issues with ELRepo packages, and those I or others have had
seem to be well addressed (not always solved -- sometimes ithe solution is to 
wait for a later updated release) by the ELRepo correspondents to this SL llist.

On this point, a question.  I have been told (but not verified as a fact) that 
the Ubuntu equivalent to the main SL repository contains (all?) packages that 
one must, for any EL family distro, find on the master (SL, CentOS, etc.) 
repository and then hunt ELRepo, EPEL, and for some items, NUX and others (in 
which case I only enable software sources such as NUX during the actual 
installation of an RPM
package that only is available in source or on  such a repository).  As I 
indicated in a previous post, I have no reason at the present time to switch to 
Ubuntu LTS (and definitely will not be going back to either
OpenSUSE or SLES); however, I am curious if the above claim is factual.  Such a 
"single" repository is much more convenient (and probably more consistent, 
without dependency conflicts) than rpmfind on the web, etc.

There is an issue with the EPEL MATE install method.

Update: SL 7.2 success on Dell consumer laptop

[Yasha Karant]

 Evidently, the issue with something on the hardware of that HP 
consumer laptop preventing the SL7.2 live KDE  boot DVD from running may 
be correct.  The live DVD iso
worked on a Dell Latitude E5550, followed by a full install from the 7.2 
4 Gbyte install DVD iso.  As a consumer laptop, Dell did not put a DVD 
reader/burner on this
model and one is not available.  Using dd, I put each of the above 
mentioned 7.2 iso images on USB stick flash drives, and did the 
testing/install from there.  No issues,
everything works.  In the future, for problem cases, I will use Ubuntu 
LTS -- but as I have all of the applications, etc., already configured 
for SL 7, it was easier for me not
to have to "support" fundamentally different distros (e.g., yum for one, 
apt-get for the other).  I do want to thank all who assisted with this 
issue, including a detailed discussion
(off list) about Ubuntu LTS.  In that regard, having checked other 
comments on the web, it does appear that Ubuntu LTS is as "production" 
"hardened" as the EL family, and in
some ways is easier to maintain, there being no need to find multiple 
repositories to get the various development tools and applications as 
does EL (e.g. EPEL, ElRepo. etc.).

The kernel Ubuntu LTS uses is:

4.2.0-35.40~14.04.1

That's because you installed 14.04.4.

Had you installed 14.04.3, you'd have 3.19.

Had you installed 14.04.2, you'd have 3.16.

Had you installed 14.04.1 or 14.04.0, you'd have 3.13.

And you could've stayed at whatever version that you'd want to use.

Basically three or four months after the release of a non-LTS version,
its kernel's made available within the latest LTS version; more or
less.



In this regard, is anyone using Ubuntu LTS in a production
environment? Is it fact both stable and (reasonably) hardened (e.g.,
not a consume/enthusiast product such as MS Win or RH Fedora)?

Yes.

On the desktop, there are far more Windows systems deployed than Linux ones...
I understand that my following comment on your last statement may be 
regarded as "off subject for this SL list".  First, in many parts of
the world other than the USA, MS Windows is not that well deployed even 
on the desktop except that many machines come with
MS Windows pre-installed.  (Aside:  I do not like the name "Windows" for 
MS Windows.  I routinely correct my students not to use
Windows, but Microsoft Windows or MS Windows.  Open systems also have 
Windows -- X windows.  All of the current "windows" GUI
systems evolved from the Xeror Star system -- officially. Xerox 8010 
Information System -- that were based upon previous "non-commercial"
research and implementation.  Evolved does not mean necessarily sharing 
the same source code, but the same "style" of basic GUI system.


The reason for the proliferation of MS Windows on the desktop has 
nothing to do with stability, hardening, or functionality.  It has to do 
with for-profit
business practices -- Microsoft is a monopoly that really should be at 
least four independent companies:  an OS environment company (MS Windows),
a software applications company (MS Office, etc.), an ISP and services 
vendor (e.g., "cloud" services and vendor rented provisioning), and an 
integrated
full systems vendor (supplying a complete hardware, environment, and 
applications software solution, similar to what Apple does with Mac 
machines).
Because of the monopoly, not quality, Microsoft has gotten the market 
share it does in the USA.  Microsoft attempted to make massive 
intrusions into high
performance locally distributed-coupled MIMD architectured machines 
(e.g., machines such as those listed in 
http://www.top500.org/list/2015/11/) , and did
not succeed because of the intrinsic limitations of the MS Windows 
model.  Architecturally, in terms of "classical" computing (not quantum 
computing, etc.),
the BSD Mach type kernel model is "better" than the Linux monolithic 
kernel; however, due to practical deployment development, as well as 
licensing issues
at the early stages of "Free"BSD, Linux has  by far won the open systems 
base.  Most of the Top 500 listed machines have some Linux base.

Linux on HP consumer laptop

[Yasha Karant]

The Ubuntu LTS ("stable" "server" "hardened" "enterprise" distro) 
bootable DVD actually works in the consumer HP laptop my wife

may have to use.

The kernel Ubuntu LTS uses is:

4.2.0-35.40~14.04.1

whereas SL 7 is using a 3.x Linux kernel.  All of the HP supplied 
hardware seems to work under Ubuntu LTS current production,
including the graphics/video card/display, sound card, LAN, pointing 
device, DVD driver/burner, and USB (including "automounting").  Is the 
issue with SL 7 on this platform the
use of a 3.x kernel rather than a 4.x kernel?   I would prefer to stay 
with yum over apt-get, but if the hardware is not supported, one faces

a quandary.

In this regard, is anyone using Ubuntu LTS in a production environment?  
Is it fact both stable and (reasonably) hardened (e.g., not a

This should work on the majority of all Linux distributions, at least if you
use UUID for the /boot partitionsi.  Use of LVM can also simplify mounting the
root parition (/) and so on - unless you use UUID for those mount points too.

I've booted several old Linux installations from hardrives put into a USB
closure. I haven't tried to do that with Windows though, that might work too -
but somehow I imagine it will freak out at some point where drive letters
won't match properly.

To get an overview you can run 'blkid' or 'lsblk -o NAME,UUID' on your system
to see all devices and their unique UUID.  These tools are also valuable when
you need to modify /etc/crypttab manually.

Thank you for that approach, but what you describe does not seem to be 
what I am suggesting.


Rather, I was going to use dd in single user mode (does the old init 
method still work with the EL 7 replacement for
init to get to single user mode, scrolling text screen, no GUI, or is 
another mechanism required?) to make an image of my booting, working SL 
7.1 installation on a 1 Tbyte external USB drive.


Then, using the boot control screen of the target laptop -- well before 
any OS boots -- I was going to set the boot device to be
USB, plug the "bootable" dd'ed USB 1 Tbyte external drive into a USB 
port on the target machine, and boot from that.  If my
present system is bootable, etc., will not the dd'ed USB drive be 
bootable (except perhaps for that efi "chunk" issue I mentioned 
elsewhere and do have any
elucidation on that point) or do I need to worry about UUID, etc., 
issues with the dd'ed "copy"?  Are new UUIDs generated/required to boot 
such an

"imaged" external USB drive?

Linux GUI use of a touchpad laptop without physical buttons

[Yasha Karant]

The typical Linux GUI uses a pointing device with three buttons; the 
center button can be emulated on two button pointing devices by 
simultaneously
depressing both buttons.  (Some track balls only have two buttons plus a 
scroll wheel -- depressing the wheel is the center "button".)


What happens with a laptop that has only a touchpad but no buttons? 
"Tapping" on the touchpad performs the MS Win 10 "button" functions, but 
what about
Linux use?  Can one configure the touchpad so that a specific set of 
regions work only for "tapping" and thus emulate a button, and the rest 
works as a regular

"glide" pointing device?

If not, is the only mechanism to use such a machine, without pointing 
device physical buttons, is to have an external (e.g., USB attached) 
mouse or trackball with buttons?


Also, are there packages to enable in Linux GUIs, and compatible with 
EL7,  touchscreen devices?  If so, does anyone have direct experience 
with the actual functionality

provided by such Linux packages -- are these end-user usable?

Best option is to remove the drive and put your own in for testing.

Alternatively, clone the drive with CloneZilla or if you're more

I did that for a few years with Fedora.  I still have a 400GB USB drive with
a couple of versions of Fedora on it (I "walked" forward my Fedora installs
so that I had a stable, previous version install on one set of partitions
and the latest, bleeding edge on another partition set).  I needed a newer
kernel than was shipping with SL/CentOS/RHEL at the time.  Just keep track
of which drive is which when you do the install and change your boot order
so the USB drive has priority if it's attached.

I tend to use this arrangement with my "work" laptops that come with Windows
installed by the IT department on the hard drive.  I boot the systems to
Linux on the external USB and can then escape from Windows when I feel the
need.

I also found the Linux install on an external drive is even portable between
hardware platforms so an option is to install to the external drive from so
other hardware and just boot the problem laptop from the external drive
after you've confirmed that the installation works.

I do not know the rules//customs of this list as to whether or not I 
should snip this.


Your last paragraph presents an option.  I have a 1 Tbyte SL 7.1 system 
on my professional (not consumer
Pavillion) with a "genuine" Intel I7 CPU (not the AMD CPU on the 
possible laptop for my wife).  If I simply got an external
1 Tbyte USB drive (e.g. a commodity Western Digital My Passport Ultra), 
and then, using my laptop that has a 1 Tbyte internal
drive, did a dd from my laptop to the external drive (a dd should copy 
all partitions, including boot) -- would this be bootable on the

target test machine?

If it is, and we elect to keep her machine, could I then, using her 
machine, do a dd from the external USB booted drive to the internal 1 
Tbyte drive of
her machine, producing a bootable Linux internal harddrive, or would 
there be a problem?  My machine does not have a EFI "chunk" on the 
harddrive,
and I have been told that without such a "chunk" -- wasted space -- a 
non EFI image will not boot on an EFI machine even if both Secure Boot 
is disabled
and Legacy Boot is enabled.  If this is the case, the image from my 
machine would not boot.  Any ideas or suggestions?


If the above would produce a booted SL 7.1 machine on my wife's new 
laptop, I presumably could put in the 7.2 install DVD and upgrade to 7.2 
without requiring the use
of a slow nextwork connection (at home, all we have is DSL -- and at my 
wife's university office, that theoretical has a 1 Gbit/sec 802.3 
connection, the actual throughput when
downloading the current 7.2 Live DVDkde ISO image was approximately 1 
Mbit/sec -- 1 percent of the nominal throughput -- mostly because the IT 
central administration fully
controlling network professionals at my institution have certain skill 
and knowledge issues that I shall not address here).


Would the above work or is the lack of an efi "chunk" a "deal breaker"?  
Can I install such an efi chunk on my machine (I have enough unused 
space in various partitions that I could use
gparted, for example, to free up such space -- if I know where the efi 
"chunk" needs to be (next to the MBR? anywhere on a bootable disk?) and 
from where to get an efi "chunk" image.

Re: SL7.2 Live DVDkde would not boot

[Yasha Karant]

There were two more postings by me with suffix [2] and then [3] pursuant 
to the situation with SL7.2 Live on this particular platform, including 
the Ubuntu description of the hardware.
As far as I can tell, all of the important hardware (harddrive and 
controller, DVD reader/burner, WNIC, NIC, pointing device, 
video//graphics card, sound card, CPU including FPU and MMU, and USB 
devices) are linux supported, including in SL 7.  Have I missed 
something?  The BIOS are "secure boot", but that is a standard issue on 
current X86-64 hardware and "secure boot" (read, proprietary closed 
source vendor controlling) can be disabled for "legacy boot".  The issue 
that causes the dracut complaint is a missing file image on the RAMFS 
that a non-installed (e.g., live) system uses.  The Ubuntu test was with 
a USB flash drive -- would that make a difference?


As far as the older text-based installer, I fully concur with the 
respondent below.  A text based installer should at least be an option 
-- it worked much better.  However, the live non-installed system 
supposedly will not use the installer.  (I point out that the only 
enterprise competitor to EL is SLES, and SLES is much more GUI and 
automated than previous EL versions and also -- from direct experience 
-- is neither easy to configure nor properly supported except for large 
commercial-style configurations.  There also is no equivalent to this 
professional email list serve for any SuSE product to which I had even 
licensed access.)


I understand that Ubuntu is not as stable as EL (although Ubuntu 
advertises support and at least at one point claimed that it could be 
used for production deployments -- something one dare not do with 
unstable non-hardened systems) -- but is the issue here simply one of 
the kernel and drivers?  Red Hat does certify EL 7 for laptops
( 
https://access.redhat.com/ecosystem/search/#/category/Laptop?sort=sortTitle%20asc=Red%20Hat%20Enterprise%20Linux%207=Red%20Hat%20Enterprise%20Linux 
),
but all I could find for EL 7 were products from Lenovo.   Lenovo is not 
that conservative in hardware, and certainly competes with both HP and Dell.


Other than stating that EL 7 will not work, are there any other suggestions?

[Very long records deleted]

First: SL, like hte upsteam RHEL, is really a stable server grade
operating system. The kernels will never be bleeding edge, with the
latest support for the latest laptop chipsets, many of which tended to
be very leading edge and off-brand. And Ubuntu tends to be leading
edge: they're not very stable for server grade systems, but rather
tend to the latest chipsets.

Second. the heavily reduced kernel and configs used by Anaconda for
the boot operating configurations can be. problematic. I've also
had problems with 7. and 7.2, that did *not* happen with 7.0. In fact,
I just installled a server with 7.0 successfully, and was able to
update, when 7.1 and 7.2 CD's were unable to boot it.

Third: the "rescue" mode should still be available, adding the word
"rescue" to the boot kernel options. I really wish they'd list rescue
mode, and *not* on that ghods-awful X based "spoke and wheel" logic
installer. The older, text based installer worked very well, took up
much less screen space, was easier to read, and had consistent layout.
It also worked *much better* for remote consoles and
virtualizatization consoles.

SL7.2 Live DVDkde would not boot [2]

[Yasha Karant]

I just verified that the SL7.2 Live DVDkde DVD I burned does boot on my 
SL 7.1 HP laptop -- very slow, but it does boot and bring up KDE.  
During the failed boot process, there was a specific file mentioned to 
post as a "bug report", rdsosreport.txt .  This file also is long, but 
it appears here for reference.  Any ideas how to fix this? Would a USB 
stick boot work?  The machine currently has MS Win 10, but if we decide 
to keep it, I would reformat the drive as a Linux only machine, with MS 
Win running as a guest under VirtualBox or the like. At the end of the 
output below appears Warning: /dev/disk/by-label/SL-72-x86_64-LiveDVDkde 
does not exist ,   This is correct; a manual inspection of 
/dev/disk-by-label/ shows windows, etc., but no SL file.


Any assistance would be most appreciated.

Although this is a consumer machine (mine is a HP but 
commercial/industrial/semi-"mil-spec", and fully supports SL), she does 
not need to use it the way I need to.
I am assuming another 3 to 5 years.  Other than a bit small in RAM for 
full 64 bit operation, it should work -- and still has a RJ-45 802.3 
jack for wired use.  From what I can tell, all of
the hardware has SL 7 intrinsic drivers.  Unless I know the box is 
"linux certified" (my HP was), the only way I can check a consumer 
commodity machine is to boot and verify that all of the hardware is 
"seen" and "works".

Thank you for that information.  However, reading the VirtualBox

cannot seem to find one that allows one to shutdown all of the

Hm, on FreeBSD most users configure a LAGG interface with both 
interfaces as member, this way changing the real interface is 
transparent to VirtualBox.



Hm, this might do the same thing:

I do not know about the Load Balancer, but after some "research", I 
found and executed as root:


systemctl stop vboxdrv.service
systemctl start vboxdrv.service

This had no effect -- but these may be the wrong commands. (Evidently,

(for which the "automagic" 802.11 DHCP hotel, etc., networks seem to be

My understanding is that 802.11 NAT, etc., connectivity from SL 7 to

spouse still has SL 6 on her laptop (her machine is underprovisioned
effectively to run a 64 bit OS and it is not cost effective to re-provision
the machine, although the CPU is an X86-64) and this works.  This is
necessary to run an application that must connect to the Internet and is not
available for native Linux, only MS Win and Mac OS X.  (For those who are
curious, the application is an USA income tax preparation/paying program of
which we have used an annual edition for many years under MS Win under
VirtualBox under SL.)  I have migrated my machines to SL 7.

Given this, if I instead connect using 802.3 to a 802.3 port and do not use
802.11, will the standard NAT I mention above work? My understanding
from previous responses/posts to this list is that the SL7 kernel series
still does provide this necessary support for 802.3 but not 802.11.

I have attempted to use a USB port 802.11 WNIC that is supported under Linux
and purportedly under MS Win 7; VirtualBox does redirect the USB device to
MS Win and MS Win "sees" it.  However, the MS Win driver is lacking, and
unless I have Internet MS Win connectivity, I do not know how to get the MS
Win driver.  Under MS Win, the driver seems to be gotten automagically from
some MS Win repository, possibly one from Microsoft.  If at all possible, I
do not want to do any non-automagic systems work on MS Win, particularly as
in most cases this seems to involve regedit (editing the MS Win 'registry",
a poorly constructed and documented structure).

Any information will be appreciated; otherwise, I will need to use my wife's
SL 6 machine.

Virtual machines should be able to nat through the system to 802.11
networks. They cannot bridge to the 802.11 network.

I regret to state that what you suggest, NAT, works fine with VirtualBox 
under SL 6 but does not work with SL 7.  In fact, when I upgraded from 
SL 6 to SL 7 is when I first discovered this -- and the information that 
I believe I received on this SL list indicated that NAT to a 802.11 WNIC 
on the host SL machine would not work because of changes in the kernel 
from SL 6 to SL 7.  If I am incorrect, please indicate how this is to be 
configured on the host, VirtualBox, and the MS Win 7 guest.  On my 
wife's SL 6 machine, what you suggest works seamlessly with no 
configuration work on my part other than to specify NAT for VirtualBox 
via the VirtualBox GUI configuration screens.

7.2 and installed the latest elrepo appropriate nvidia driver and 
utilities rpms.   However, the system would not boot until I modified 
/etc/fstab to eliminate mounting of a number of the ext2 partitions.  
Hence, I plan to migrate all partitions to ext4 as this purportedly can 
be done in place.  I cannot find a utility or script that does this 
automagically, nor specific EL7 instructions.  I have found a set of 
instructions by which one migrates ext2 to ext3 and then ext3 to ext4.  
I have appended these below.  Has anyone done this and, if so, does the 
procedure below "work"?  is there a better procedure or an automagic 
utility?


I did a perusal of this list, but can find no such instructions for 
SL7.  Given the number of changes between many of the older SL major 
releases and the current one, it seemed wise to use a SL7 proven 
methodology.

It is possible to enable journalling, extents, directory indexes, and 
uninitialized block groups for a modest speedup.


First, ensure that your e2fsprogs is up to date. Newer versions have 
many, many bug fixes.


Second, ensure that your filesystem is in good working order!

|# umount /dev//DEV/|

|# e2fsck -fy /dev//DEV/|

Next, to change an ext2 filesystem to ext3 (enabling the journal 
feature), use the command:


|# tune2fs -j /dev//DEV/|

To enable the ext4 features on an existing ext3 filesystem, use the 
command:


|# tune2fs -O extents,uninit_bg,dir_index /dev//DEV/|

WARNING: Once you run this command, the filesystem will no longer be 
mountable using the ext2 or ext3 filesystem driver!


After running this command (specifically, after setting the uninit_bg 
parameter), you MUST run fsck to fix up some on-disk structures that 
tune2fs has modified:


|# e2fsck -fDC0 /dev//DEV/|

Finally, edit */etc/fstab* to change the filesystem type to ext4.

Notes:

 * Running fsck will complain about "One or more block group descriptor
   checksums are invalid" - this is expected
   <http://marc.info/?l=linux-ext4=125834107118172=2> and one of
   the reasons why tune2fs requests to fsck.
 * By enabling the *extents* feature new files will be created in
   extents format, but this will not convert existing files to use
   extents. Non-extent files can be transparently read and written by
   Ext4. You can convert files to extent format by running chattr +e on
   each file. Starting in e2fsprogs 1.43 you will be able to run e2fsck
   with -E bmap2extent -fy to do this conversion.
 * If you convert your root filesystem ("/") to ext4, and you use the
   GRUB boot loader, you will need to install a version of GRUB which
   understands ext4. Your system may boot OK the first time, but when
   your kernel is upgraded, it will become unbootable (press /Alt+F+F/
   to check the filesystem).
 * If you do the conversion for the root fs on a live system you'll
   have to reboot for fsck to run safely. You might also need to add
   /rootfstype=ext4/ to the kernel's command line so the partition is
   not mounted as ext3.
 * *WARNING*: It is NOT recommended to resize the inodes using
   resize2fs with e2fsprogs 1.41.0 or later, as this is known to
   corrupt some filesystems.
 * If you omit "uninit_bg" on the tunefs command, you can skip the fsck
   step.

Re: 7.2 update instructions

Apologies, but I do not understand the "+1"; is this approval to post 
additional commentary on this matter, or, again, is this discussion not 
suitable for this list? I did not initiate the matter of the ACM view or 
curricular recommendations, in contrast to that of an information 
technology approach; but there seem to be fundamental misconceptions 
concerning the fields of computer science and engineering in the 
commentary, just as I have met some "applied" physicists who have 
misconceptions about fundamental physics (e.g., high energy physics and 
general relativity).  (I mention fundamental physics because that is the 
basic reason for the existence of both Fermilab and CERN -- at both 
institutions, EL is the operating environment to enable the research, 
rather than DEC VMS of a previous epoch.  Those in the EL community gain 
from this use.)


For Lamar, who evidently has looked at my not-recently-updated academic 
home page, the item you mention is posted there from another source (I 
do not have any graphics artists to support my work, and do not have the 
spare time to do the stick figure material you see) that I thought was 
credited.  I use this introduction to AES (and cryptography in general), 
along with a Conan Doyle short story, as my part of the "dog and pony 
show" my department does on an annual basis to recruit high school 
students to come to our ABET accredited programs as undergraduate 
majors. If a person cannot handle mathematics, including that behind 
encryption, then, regrettably, computer science and engineering probably 
is not a good fit (nor would physics be).  When I teach a course 
involving encryption, I cover it with greater depth than what you see in 
the cartoon -- but I still have the students read the cartoon to get 
some background before I teach the mathematics and then the cryptography.

I can't answer that; a moderator would need to.  I would personally
welcome a direct e-mail with the explanation myself, as my .edu is
currently investigating 'CS' curricula (where 'CS' is the

And for the list, one of the more fascinating things you are likely to
ever read is Yasha Karant's 'A Stick Figure Guide to the Advanced
Encryption Standard (AES)' which is available at
http://www.csci.csusb.edu/ykarant/cryptography/aes-cartoon.pdf ; I
certainly found it interesting.

My paragraph was simply there to let you know that there are probably
many more IT folk here than CS folk, and IT folk tend to have a very
hands-on and practical 'here's the standard way to do it' answer and an
eye towards maintainability, and all of that is just a part of the IT
mindset.  Neither is the more correct mindset; the mindsets are just
different.  A CIS-mindset is yet even more different, but that's not
nearly as well represented here, nor are the CE or SE mindsets, but the
IT mindset is very much predominant here.  As well, it was to serve to
let the list as a whole know that there are different mindsets out there
that are very different from the typical sysadmin IT-centric mindset.

While this has nothing to do with what you originally posted, I'll 
bite.  In my case I have set up a separate logical volume for /home

volume group as the LV for / is irrelevant; in my case they are on the 
same VG, and I tell (told, in the case of one 'upgrade') the installer 
to use a particular existing LV for /, a particular partition for 
/boot, another LV for swap, and the last LV for /home.  All are set to 
format *except* the one for /home. It took a bit of time to get used 
to the EL7 installer's way of doing mount points, but now that I've 
used it a few times I really prefer it to the old way for many (but

Presumably, to move existing to-save partitions from the older file

Re: 7.2 update instructions

[Yasha Karant]

As I am using SL 7.1, the answer below should suffice (assuming it works 
seemingly as advertised).
I fully understand from past experience that EL, unlike SLES, does not 
allow an upgrade in place for major releases,
only minor releases (e.g., upgrade in place SL 7.1 to SL 7.m for 
whatever m turns out to be).  For SL N to SL N+1, etc., one must be 
willing to sacrifice whatever is on the partitions that must be 
overwritten (/ , /boot , /usr, /bin/ , ...) but not on what can be 
"untouched" during the N to N+1 process (e.g., /opt , /usr/local if this 
is a separate partition from /usr , ... ).


As the "old" partition scheme is increasingly considered "obsolete", for 
the new layout scheme, how does one not overwrite the entire file system 
other than having two separate hard drives, a "system" one and and

7.2 update instructions [2]

[Yasha Karant]

I have found the following:
http://unix.stackexchange.com/questions/249330/centos-7-2-now-to-update

CentOS 7 (through and including 7.1) offered the

|Applications | System Tools | Software Update|

applet. This applet allowed users to update CentOS 7.

Where is the applet in 7.2 v1511? I do not see that anymore.

Yes, I know of |yum -y update|. I executed the |yum -y update| command, 
which is how I got from CentOS 7 to CentOS 7 (7.2 v1511).


1 Answer

This is a bug in the Upstream(Redhat) which has been reported: 
https://bugzilla.redhat.com/show_bug.cgi?id=1290868


You can solve this issue by installing the |gnome-packagekit-updater| 
package with this command.


|sudo yum install gnome-packagekit-updater |

Once this package is installed you will find the ICON where it used to 
be. i.e: Applications | System Tools | Software Update


You can also start the GUI Updater from command line once it is 
installed by invoking this command:


|sudo gpk-update-viewer |

End quote.

I understand that the above applies to CentOS 7.2, but SL 7.2 and all 
other RHEL re-distributions, not binaries licensed from Red Hat for fee, 
now must go through the "Red Hat subsidiary" CentOS for the source from 
which to build a distro (e.g., SL 7.2) . Thus, the same procedure should 
work if one knows how to point the upgrade path to a local DVD.   Note 
that I use MATE, not Gnome, as my primary GUI system.  Must I use Gnome 
for the above correctly to function, or will an invocation from a 
command line in a MATE terminal GUI application suffice?


Has anyone done the above, and, if so, what cautions (warnings, 
"gotchas") are needed?


Note that I have attempted to install the above gnome-packagekit-updater 
with the following error diagnostics and failure:

want recommendations for 802.11 USB interface

[Yasha Karant]

I need a USB 802.11 dongle.  I have tried one and am returning it 
because the driver failed.


I would prefer a dongle that can handle IEEE 802.11 b/g/n on USA

SL 7.


Anyone with positive (or negative) experiences?

802.11 USB

[Yasha Karant]

Although from a previous thread it appears that KVM as a type 2 
hypervisor (not "bare iron" but under a Linux host) somehow can 
bridge/NAT the 802.11 host Internet connection to a MS Win guest, it 
should also be possible to use a 802.11 USB adapter (without serving as 
an advertisement, but simply as a reference for a long list, see: 
http://www.newegg.com/Product/ProductList.aspx?Description=802.11ac=ENE), 
detach it from the Linux host, and then attach it through VMware Player 
to the guest OS.  (Note that for some USB devices, VirtualBox posts a 
"fail to create proxy" error and will not in fact provide the affected 
USB device to the guest OS.  Thus far, VMware Player has been able to 
attach such devices to the guest although these were rejected by 
VirtualBox.)  For MS Win 7 Pro and presumably later MS Win guests, there 
should be a driver for the USB 802.11 device, and the 802.11 network 
should then allow the device to communicate -- one laptop, two 802.11 
NICs and connections (one host, one guest).  Is there any recommendation 
(including from the vendor supplier list above) for such a device?  
These seem quite inexpensive at US$15 or so.  The reason I am posting it 
to SL is that it would be nice to have a device that could be recognized 
by both SL and by MS Win in the event I ever wanted to use a second 
Linux 802.11 connection.

NICs aren't listed under "/dev". They're symlinks under
"/sys/class/net/" that point at "/sys/devices/...".
At a previous epoch, both VMware and VirtualBox allowed a MS Win guest 
to "share" the Linux host 802.11 Internet connection, typically through 
NAT if my memory serves.  This no longer works evidently because of a 
change in the kernel.  Is there any modified driver that can overlay a 
"virtual" NIC on the real 802.11 NIC?  Can the kernel be "tricked" by 
such an overlay?  Is there a possible alternative (modified, "hacked") 
kernel that will allow this?  Is the only alternative to obtain a second 
802.11 NIC and then have the Linux host not use this hardware but have 
it used by the virtual machine (e.g., MS Win guest)?  My laptop has an 
external "hardware" expansion insert slot, and I might be able to find 
such a 802.11 NIC.


Presumably, a "bare iron" hypervisor controlling the real hardware 
platform and then allocating virtual machines and their environments 
(supervisors), e.g., a SL7 VM and a MS Win VM under the hypervisor, 
would work if the hypervisor time multiplexes the 802.11 NIC between the 
two VMs.  However, one is then forced to a hypervisor controlling the 
hardware (security issues) along with the additional overhead of a full 
time hypervisor.

So you want the guest to have full control over the wireless network
adapter?  That is possible, but only through a hypervisor ... and these
days, unless the adapter supports PCI SR-IOV [1], you need to disable
the interface (unload all drivers, unconfigure it) and allow your guest
to access the PCI interface directly (so called PCI passthrough).

With PCI SR-IOV support (this requires hardware support), you can
actually split a physical PCI device also supporting SR-IOV into
multiple "virtual functions" (VF) which results in more PCI devices
appearing on your bare-metal host and you can then grant a VM access to
this VF based PCI device.  For network cards, that also includes a
separate MAC address per VF.

Neither VMware nor VirtualBox ship as part of SL.  KVM does, and USB

on my laptop.  It just works, and it's already part of SL; why not use it?
Performance is very good in my experience, and I'm running a few pieces of
software in Win 7 for the same reasons as you.  You're also far more likely
to get useful help using KVM, either from the list or from other sources,
such as the Red Hat or Fedora documentation.

 From the KVM site (http://www.linux-kvm.org/page/Management_Tools) that has a
RedHat logo, there is a list of management interfaces, including VMM (Virtual
Machine Manager -- https://virt-manager.org/screenshots/ ) that also appears
to be a Red Hat entity.  Anyone using VMM?  VMM appears to allow a true host
OS (supervisor, not hypervisor) with the VM ("hypervisor") running under the
OS (as with VMWare workstation/player or VirtualBox), thus booting an OS, not
a hypervisor that actually provisions for guest supervisors.  Is this correct?

This was a bit confusing for me (getting late, so probably stupid to reply now).

But  KVM is the core hypervior.  It is in fact just a kernel module which
you can load at any time on systems with CPUs supporting hardware
virtualization (VT-d or similar, most modern Intel, AMD and IBM Power 7/8
supports KVM).

libvirt is the management backend, which provides a generic API.  libvirt can
be used against other hypervisors as well, such as Xen, but probably more
often used with KVM.

qemu-kvm is the KVM virtual machine process.  Each qemu-kvm process is started
per VM.  You seldom start these processes manually, but they are kicked off by
libvirt.

virt-manager is a management GUI front-end.  And virsh is a console based
management tool.  Both connects to the libvirt API.

Further, you can also download an oVirt Live image and boot that on a
bare-metal or virtual machine.  oVirt can then connect to libvirt and provide
an even more feature rich management tool.

virt-manager and oVirt can also connect to several systems running libvirt
simultaneously, so you can manage more hypervisors from a single front-end.
And there are probably even more front-ends, like "Boxes" (not really tried it).


I dunno much about vmware stuff, so I will refrain to comment that.  But
VirtualBox is also two-fold.  My experience with VirtualBox is now quite old
(5-6 years ago).  You can start VirtualBox guests without a kernel support
module loaded, which would work on most hardware.  But performance was not too
good at all.  If you got the init.d script to build the kernel module, you
could get quite acceptable performance.  However, I see VirtualBox more like a
single package which gives you both hypervisor and management tool in a single
software package.

Even though VirtualBox is more a "single unit" and KVM/Qemu/libvirt consists
of more components ... you normally don't notice that when you start VMs via
the management tools.


I hope this gave a broader perspective.

Thank you for your detailed exposition.  My primary concern is that I do

have enough security vulnerabilities with a "hardened" supervisor such

performance, although the USB interface on VMware now does seem better 
than VirtualBox that evidently still has issues (one of the mysteries).  
As neither VMware player nor VirtualBox seem capable of providing a MS 
Win guest with any form of Internet access to an 802.11 connection from 
the host (in both cases, the claim from a MS Win 7 Pro guest is that 
there is no networking hardware, despite being shown by the guest as 
existing), it is possible that the "native" (ships with) vm 
functionality of EL 7 may address this issue.  Note that

For a dynamic connection even with a wired Ethernet you should use the

Neither VMware nor VirtualBox ship as part of SL.  KVM does, and USB 
passthrough works very well with Windows 7 running in a KVM virtual 
machine on my laptop.  It just works, and it's already part of SL; why 
not use it?  Performance is very good in my experience, and I'm 
running a few pieces of software in Win 7 for the same reasons as 
you.  You're also far more likely to get useful help using KVM, either 
from the list or from other sources, such as the Red Hat or Fedora 
documentation.


From the KVM site (http://www.linux-kvm.org/page/Management_Tools) that 
has a RedHat logo, there is a list of management interfaces, including 
VMM (Virtual Machine Manager -- https://virt-manager.org/screenshots/ ) 
that also appears to be a Red Hat entity.  Anyone using VMM?  VMM 
appears to allow a true host OS (supervisor, not hypervisor) with the VM 
("hypervisor") running under the OS (as with VMWare workstation/player 
or VirtualBox), thus booting an OS, not a hypervisor that actually 
provisions for guest supervisors.  Is this correct?

two mysteries

[Yasha Karant]

Perhaps someone else has experienced what I related below and can 
comment -- SL 7x.


1.  Over break, an SL7x machine I had configured for a colleague had 
ceased to work.  There was a power outage and upon reboot, the Dell BIOS 
was not recognizing the Nvidia video card -- somehow the Dell BIOS had 
changed state.  Upon physical removal of the Nvidia card and yum erase 
of the relevant Nvidia X11 driver RPMs, X11 was working, but now there 
was no network connectivity.  I routinely run gkrellm to get a quick 
view of machine function; in this case, the 802.3 NIC was transmitting 
but not receiving any response from the central DHCP server.  This was 
working before the break (no static IPs generally are allowed by the 
university IT to centralize and police all services, both for 802.11 and 
802.3) .  After some investigation, I discovered that the DHCP, etc., 
services were no longer trusted by the SL7 firewall.  I reconfigured to 
trusted.  The 802.3 NIC that had been identified by gkrellm as eml now 
is P2P1 and the system connected; the end user was satisfied.  The 
central IT claims to have made no changes (no new CA, etc.).  Any ideas 
as what might have happened?  Could Network Manager have activated?  For 
802.3, I prefer to use a manual configuration, not NetworkManager.


2.  The other issue concerns VMware and VirtualBox -- not EL per se, but 
someone on this list may have experience with the problem. Because of a 
lack of licensing funds, I am using VMware Player and VirtualBox (not 
simultaneously).My default is VirtualBox, but if necessary and as a 
test, VMWave Player.  Both are running images of MS Win 7 Pro that are 
simply the transformation of one virtual machine guest file format to 
the other.  Neither connects to the 802.11 host NIC and thus neither has 
Internet connectivity (a separate matter).  Both have bidirectional 
shared folders with the host.  Both have the extension packs, tool sets, 
etc., installed as specified by each.  VMware is able to use all USB 
devices that I connect to the host.  However, VirtualBox is not, 
producing an error that has been observed many times on posts I found on 
the web (Failed to create a proxy device for the USB device. (Error: 
VERR_READ_ERROR) ).   Has anyone on this list observed the VirtualBox 
USB issue?  USB 2 service is installed in for VirtualBox, vboxusers has 
the correct user entry, etc.  Some USB devices work, others do not -- 
but the same device that did not work for VirtualBox did work for 
VMWare.   Note that I must use MS Win to work with these devices as the 
application software for the device in question is *NOT* available for 
linux, the device is proprietary (no source code available), and 
CrossOver/Wine does not support USB -- forcing the use of a VM running a 
MS Win guest.

Re: a year later - CERN move to Centos - what are we doing?

[Yasha Karant]

For the immediate future, we plan to continue with SL 7.  When EL 8 
emerges, we may need to re-evaluate the situation.  That being stated, 
for non-CERN groups (that is, groups neither employed by CERN nor in one 
of the collider collaborations), is there a CERN equivalent to this SL list?
What "services" does linux.supp...@cern.ch provide?  I understand that 
for CERN groups, the service presumably is close to what RH provides to 
contract for-fee customers, with the proviso that the CS persons with 
CERN groups know what they are doing.  What is available to non-CERN 
groups/persons?  If this is information that is not relevant to the 
entire SL list, a private email would be appreciated.

Now CERN Linux el7 comes in and I see the machines installed as 7.1 
stay there,

no automatic update to 7.2. Odd.

Then here, I see same with CentOS7 - no automatic updates by default, 
no automatic
updates to latest point release, 7.1 machines stay at 7.1. (I do not 
have any SL7 to compare)


So I am puzzled by all this. Maybe I should ask google: "is centos7 
supposed to self update to latest point release?"


In both cases you should get automatic updates to latest release 
(while using default yum repository definitions), if this is not the 
case: please report the problem.





Then I takes quite a bit of work to get automatic updates to work at 
all on CentOS7

(CERN el7 seems to be okey):

a) The yum.cron package is crazy - each time I need to use yum, I 
have to wait
until it finishes some useless background tasks. Then "yum remove 
yum.cron" has
no effect because all the cron jobs are part of the main yum package. 
Go figure.


b) the CERN yum-autoupdate package, which we use for SL6 updates, 
depends
on a yum plugin not available anywhere (except from a CERN repo) and 
then actually
does not work out of the box because of strange interaction with 
systemd - only works after a reboot.


bb) then it does not send any email about updates - the el6 
yum-autoupdate did this,

where did this function go?!?


again: if you encounter such problem(s) - please report.



(Hmm... maybe I should try these auto update scripts from the SL7 
repository?)



So as they say, 1 step forward, 2 steps back.

attempts to autodetect settings, which has gotten fairly reliable

That is my understanding. In SL7, there should be no xorg.cong file by

still be used if it is present. Graphical settings are supposed to be

Precisely the problem.  The Nvidia X11 driver package seems to have

Uninstalling both the kmod-nvidia and the nvidia-x11-drv should do the 
trick.  It may leave behind the xorg.conf for you to manually remove, 
depending on how the rpm was configured during build.


It is the kmod-nvidia module which does the nouveau blacklisting using 
/usr/lib/modprobe.d/blacklist-nouveau.conf.


-Mark

Mark,

You were correct.  After removal of the Nvidia PCI add-on card, and thus 
getting to a scrolling terminal screen (ctrl-alt-F2, etc.), login as root,
rpm -qa | grep elrepo , yielded the two packages.  yum -remove one of 
the packages (after a long wait to check many repositories) removed both 
packages (the other as a dependency), reboot, clean X11 GUI login.   
Thanks for the hint.  Presumably, in a future iteration of the elrepo 
packages, there will be an automagic test to verify that a Nvidia board 
really is present, and, if not, use the stock driver as if no elrepo 
Nvidia package had been installed.

Dell Precision T1700 default xorg.conf file needed

[Yasha Karant]

The ElRepo Nvidia driver seems to have erased (not backed up) the 
default X11 xorg.conf file on a Dell Precision T1700 with an addon Nvidia
card.  With the Nvidia card in place, the system will not boot (blocked 
by the Dell bios); the card has been physically removed. The system boots
to a standard terminal login prompt and will allow login; however, no 
GUI login, and both startx and xinit fail.  SL 7.1 .  Does anyone have a 
stock xorg.conf file or URL for one that will work on this platform and 
environment (including a pointing device, etc.)?  Does anyone recall the 
command that will "automagically" rebuild a working xorg.conf file?  I 
can play with this, but it is easier to get this operational.

On 12/28/2015 01:37 PM, S A wrote:

Hi,

I was out for holiday last week and came back to my SL 7.1 desktop needing a 
slew of updates.  I had been running VirtualBox-5.0-5.0.10_104061_el7-1.x86_64 
against kernel-3.10.0-229.14.1.el7.x86_64 with out issue.  After installing the 
latest kernel mentioned by Etienne, and attempting to rebuild the vboxdrv 
modules, I had similar failures.  Afterward, I attempted to upgrade to 
VirtualBox-5.0-5.0.12_104815_el7-1.x86_64, I discovered the libdevmapper issue 
noted in the previous post which prevented the newer version from installing.

It seems that there is a VirtualBox bug filed against the EL7.2 3.10.0-327 
kernel noted here: https://www.virtualbox.org/ticket/14866 which may be causing 
the issues you are encountering.  Unfortunately, the testing build for EL7: 
https://www.virtualbox.org/download/testcase/VirtualBox-5.0-5.0.11_104721_el7-1.x86_64.rpm,
 does not install due to the same libdevmapper issue.  I had hoped maybe the 
devmapper issue was introduced in builds between the latest testbuild and the 
release build for 5.0.12, no such luck.

I have device-mapper-libs-1.02.93-3.el7_1.1.x86_64 installed, but it seems that 
the VirtualBox package is calling for device-mapper-libs-1.02.97, which doesn't 
seem to be available for SL7.  The CentOS and Oracle Linux public yum repo's 
latest version is device-mapper-libs-1.02.107-5.el7.x86_64.  Is that in the 
pipeline for release to SL7 soon?

Thanks!
I am confused.  As I thought I understood the current EL situation, Red 
Hat owns CentOS and distributes EL full source, per GPL, Linux, etc., 
licenses, through CentOS for all non-RH rebuilds (e.g., Oracle) to use 
(sans Red Hat logos, services, etc.).  In this case, two questions:


(1) Is Fermilab/CERN not funded well enough to have the same 
rebuliding/packaging resources as Oracle just to rebuild from the RH 
CentOS sources, and thus is delayed in production binary (RPM) release 
compared to Oracle?  Both Fermilab and CERN are funded through their 
respective governments that support fundamental research.


(2) If (1) is true, during the interval before the "current" RH 
production release is a SL release, can one simply use the CentOS or 
Oracle RPMs (e.g., in this case, 
device-mapper-libs-1.02.107-5.el7.x86_64.rpm) to maintain compatibility 
with Oracle licensed-for-free products (e.g., VirtualBox)?

What version of hplip is installed on the system?

Akemi,

That is what I tried at first.  It would not install and properly 
function, claims not withstanding.  I tried yum install (from a 
terminal, not the GUI) but it would not work due to a python error (too 
old a version, ... ) -- I did not record the error message, and thus 
only am relating from memory.  When I get to the machine on which I 
tried this, I will record the exact errors.

I've had good luck with imapsync[1] to make backup copies to another 
IMAP server.  It's smart and useful for migrating many accounts from 
one imap service to another, but it's also useful for just syncing one 
account.


When we migrated to the cloud, I had expectations of the cloud just 
vaporizing or turning into a thundercloud and taking a dump on us, but 
it has been OK.  MS hasn't lost any of our mail. Thunderbird does 
occasionally re-download all folders on my various systems (fedora, 
windows, CentOS 6) which takes a long time for my years of email 
archives due to their throttling (which has vastly improved as well -- 
use to take a week with many fatal errors while using it normally; now 
completes in about a day and rarely a failure).  The root cause of 
this is unknown - could be when they move me to another 'pod' or when 
they muck with my folders (redownload happened recently when they 
added Clutter).


[1] http://imapsync.lamiral.info/


At present, my department chair is suggesting:

http://www.mailstore.com/en/mailstore-home-email-archiving.aspx

that is licensed for free for home use -- presumably meaning single 
user unless one really must work from home for this use.


Note that this application does not support Linux.  Hence, my plan is:  
under SL run VirtualBox running MS Win 7 pro running the above 
application, but save all of the produced files on the Linux side 
using VirtualBox shared folders.  Many of my colleagues here do not use 
MS Win as the primary OS environment; most use Linux or MacOS X with 
open system extensions (e.g., fink).  The colleague who suggested the 
above application is using MS Win on his workstation.


Has anyone had any experience with this sort of scheme or this application?

I am guessing that the above Nvidia chip set is (fully) supported by the

The easiest way to find the right driver version is to install
nvidia-detect [1] from ELRepo and run it. For example:

$ nvidia-detect -v

This device requires the current 346.47 NVIDIA driver kmod-nvidia


I have this working on my SL7 X86-64 workstation.  The stock driver (noveau)
needs to be fully disabled.

If you use ELRepo's kmod-nvidia package [2], you do not need to do any
of this manually. It will disable nouveau for you. Just set up ELRepo
as Pat suggested and run 'yum install kmod-nvidia'.

Nvidia routinely updates the proprietary Nvidia driver code.  At each

ELRepo's nvidia packages stay current with the updates released by
Nvidia. There are 4 legacy versions in addition to the current
kmod-nvidia:

The kmod-nvidia-340xx driver supports GeForce 8xxx and 9xxx series
GPUs, GT2xx and Quadro series
The kmod-nvidia-304xx driver supports GeForce 6 and 7 series GPUs
The kmod-nvidia-173xx driver supports GeForce 5 series GPUs
The kmod-nvidia-96xx driver supports GeForce 2 to GeForce 4 series GPUs

'nvidia-detect' identifies your device and tells you which one to use.

I highly recommend you subscribe to the elrepo mailing list. Recently,
Nvidia released a version that drops support for a number of commonly
used cards. ELRepo proactively dealt with the issue as seen in this
thread:

http://lists.elrepo.org/pipermail/elrepo/2015-January/002508.html

Like all other ELRepo's packages, they are built for RHEL and its
rebuilds (including SL).

Akemi
Excellent with one remaining question:  after installing the ELRepo RPM 
instead of the much more messy Nvidia driver, will Nvidia CUDA 
(including the Nvidia nvcc compiler) system function?  Will CUDA see 
the Nvidia GPU cards with the ELRepo driver as with the Nvidia driver?

reboot the system.

Note that this was not done under X11 or a window manager, but from within a 
plain ANSI terminal screen (e.g.,
CTRL-F4 to get the fourth terminal.

After that, a reboot will (eventually) show the Nvidia splash screen and then a

Re: SL7 client for Microsoft ActiveSync

I appreciate the various replies, some of which have been off-list.

One such off list is:

[Entity X} is not yet on the ActiveSync client but
we have been using MS Exchange 2010 for a few years now.
the linux IMAP clients were at first problematic but eventually they
sorted them all out and there are plenty of people who still use
thunderbird to read their mail without significant trouble except
the server getting confused every once in a while.  I think you
can expect that office365 cloud-based email, which my wife's university
already uses, will work out the imap kinks in the next bug release or two.

a workstation and as a server environment,
one needs workstation applications that communicate/interoperate with 
those commonly available from other environments
(the two primary examples being proprietary MS Windows and highly 
proprietary Mac OS X -- albeit the latter has BSD internals
and thus can be adapted to open standards -- in addition to the various 
smart phone, tablet, and device environments such

as Android or IOS).

Fully function is not a weasel word -- it means that if a set of 
services are available from some service or application -- then all of 
these functions can be accessed with equivalent results as if the 
native proprietary application were used.  Evidently,
using IMAP and SMTP -- open public IETF standards -- work, but very 
slowly, with the current MS Office365 email service.
The web based interfaces are slow as well.  This leaves us with the only 
alternative -- until MS works out the Office365 cloud based email imap 
kinks in the next few maintenance minor releases (bug releases).  I 
am not holding my breath in that MS may view this as a method to force 
linux out of the USA professional/commercial workplace.

has explained that only a client compliant with Microsoft ActiveSync will
fully function with this imposed proprietary closed system service --

It's better than some, and a lot more robust than many IT department's
internal services. I've seen Linux favoring shops fail to maintain
complex email services, and especially calendar functions, and had
their client company finally throw in the towel and switch to
Office365 or GMail. And be clear, this is not a Scientific Linux
problem, it's a my company chose to use a hosted, commercial, closed
mail server, and I need to deal with it.

If it does straightfoward IMAP, then any of the dozens of built-in
IMAP capable clients should work for email access, including the
default evolution product in SL  And there are hundreds of good web
guidelines for evolution access to Office365: look around.

What you won't get with a pure IMAP client such as my old favorite
pine or other pure IMAP clients, is access to the user address
search engines, calendar functions, integrated address books, etc.,
etc. Those matter to some folks, especially if you need to book a
meeting room and can only use the Exchange clients to do so.

Part of the problem is the weasel words fully function.  Any client
that wants to deal with the upstream office365 server is typically
webscraping the webmail access. That webmail access tends to *suck* in
terms of performance, especially with complex and bulky email systems.
It's why even I maintain a Windows environment with an Outlook client:
I find that waiting a full minute for a new filter to be enabled and
waiting waiting waiting to get a refreshed screen to work with
is unacceptable, and the web based access to Office365 has been
unacceptable for me. But I hammer my email with many alert and
notification systems and cron job reports.


Is there any such client (Microsoft or otherwise) available for Linux, and
in particular, SL 7?  All that I found on the web is to use proprietary
Microsoft Outlook under a MS Windows environment under a virtual machine
(e.g., VirtualBox) under Linux -- not a solution I want for regular email
service.

See above. Start from evolution, which is a popular and well
supported client in RHEL and in SL  and work your way out to a client
that works as well as you can expect.


For anyone currently using (by force or choice) Microsoft ActiveSync, does
it in fact support the functionality of IMAP and SMTP without staying
completely with a Microsoft proprietary environment, including Microsoft

Presumably, any application that will run under CentOS, in particular,
CentOS 7 that is the RHEL source release for other ports, such as SL 7,
should be able to run under SL.  My understanding is that SL 7 is not
built from the actual RHEL 7 source that is used to build RHEL 7 that is
licensed for fee, but from the RHEL packaged CentOS source (CentOS now
effectively being a unit of Red Hat, a for-profit corporation) that is
used to build CentOS 7 (that, as with SL 7, is licensed for free as a
binary installable executable system that requires no building from
source per se).

SL is built from the source that Red Hat has provided .  It is built 
from the same source that all rebuilds can build from. There is no 
such thing as RHEL packaged CentOS source .

Please correct me if I am in error.  RHEL, binary licensed for fee, is 
built from a source that RH does not seem to release.  Rather, RH 
releases, through the RH subsidiary CentOS and a GIT mechanism, a source 
for all rebuilds, supposedly including CentOS.  Thus, SL and CentOS are 
built from the same source, but the actual RHEL source may or not may in 
fact (claims to the contrary notwithstanding) be the same, as no one 
outside of RH or a RH licensee actually sees the source for RHEL.  If 
RHEL also is built through a GIT mechanism, I am assuming that the 
Internet path to the RHEL GIT is not the same as that to the public 
rebuildable CentOS GIT.  In the event that Fermilab or CERN has licensed 
the actual RHEL 7 source as a RHEL licensee, would personnel at either 
non-RH entity be allowed to comment if in fact there were non-trivial 
differences between the actual RHEL 7 source and the rebuildable 
CentOS 7 source?  Trivial differences would be the presence of RH logos 
and splash screens, each of which is replaced by whatever the rebuilder 
is using (SL for the SL rebuild) -- but all of the internal intellectual 
property references in the source code still (presumably) mentions RH in 
both the actual RHEL 7 source and the CentOS 7 rebuildable source.

Re: Docker

[Yasha Karant]

You have answered my question.  There are, roughly, using old 
terminology, heavy-weight containers and light-weight containers.  
VMware used to offer heavy-weight containers that would run any MS Win 
application under Linux (presuming the same underlying ISA), but were n 
some instances extreme resource hogs.  Docker thus seems to be a 
light-weight container with strong limitations as to the differences in 
the underlying environment and OS structures (again, same ISA -- 
different ISAs require rather different approaches, including the old 
Sun approach on SPARC workstations of having a Sbus IA-32 coprocessor 
board to run a licensed copy of MS Win).

static linked ISA executables

[Yasha Karant]

Suppose one has an ISA executable file (e.g., an application that is a 
native binary executable, not an interpreted executable) that works 
under a different Linux distribution -- for clarity, call that OTHER 
Linux.  OTHER may use a different kernel and a different glibc than SL, 
and the executable may be IA-32, not X86-64.  If under OTHER the 
executable file is built with only static libraries -- no dynamic .so 
calls -- will it execute under SL 7?   That is, when system (kernel) 
calls are made by the executable, will the use of a different kernel and 
glibc generally cause the executable to fail? I am restricting the 
discussion to the X86-64 ISA, not an arbitrary ISA for which OTHER may 
be available.

It depends on how statically it is compiled. I have seen things which 
were listed as static but only for everything but glibc. In that case 
you need to install the x86_32 glibc to get it working. That said.. 
when things are super static you can end up with hunt the file I 
need.. it is static but is looking for a file which is in a 32 bit 
directory.


So some of the time it will work, some of the time it won't. Without 
knowing more about what ldd and say strings says about the 
executable.. not sure which category your executable will fall in.

Stephen J Smoogen.

My intention is this.  There exist applications on various other 
distributions (Fedora, Ubuntu, SuSE, etc.) that do not exist and will 
not build under SL 7.   The intent would be to setup a development 
machine of the other distro, build the application from source as static 
as possible (with bloat by this mechanism), include whatever directories 
or files that need to be present, and then run the thing under SL 7 .  
In a worst case, rather that using a physical machine, install the other 
distro in a virtual machine under VirtualBox (that runs very well under 
SL 7) -- with enough disk space assigned to the Virtual Box machine to 
allow for such a build.  Some applications (such as a full window 
manager) I would not consider, but there are others of more limited 
generality that I would.

Adobe flash plugin replacement for Firefox

*Linux* Mozilla, Firefox - NPAPI (Extended Support Release) 
11.2.202.425
Chrome (embedded), Chromium-based browsers - PPAPI  16.0.0.235


I have searched on the web for PPAPI for Mozilla Firefox; the most I 
could find was:


https://bryanquigley.com/crazy-ideas/adobe-flash-on-firefoxlinux-eol-summaryrecap

Other options considered.

 * We default to Chromium  – nope, let’s specifically NOT switch
   browsers over Flash.
 o Outcome: That would send the completely wrong message.
 * We default to a compatible Flash alternative (Shumway, Gnash,
   Lightspark)
 o Outcome: That would just be a stop gap measure.  And we’ll
   always be playing catchup.
 * We add PPAPI support to Firefox ourselves / Hack it in
 o Outcome:  Non-starter.  Unless Mozilla adds it we don’t want the
   maintenance burden.


End quote.

Note that because Flash is not an ISO standard (unlike PDF), compatible 
Flash alternatives evidently always will be reverse engineering
and thus playing catchup.  Unfortunately, many end users and many IT 
units (that are business management based with little or no
concern for computer science but only for-profit vendor technology) use 
and thus demand Flash.


Any suggestions?

What's the problem here?  Flash is available for 32 and 64-bit browsers,
use their yum repo.  Just because the version is older than others,
doesn't mean it is insecure or won't do the job.




Hi Chris,

Hi Yasha,

I do not know if this will help at all, but I install
the You Tube All HTLM5 extension on all my customer's machines to
get them off of Flash as much as possible:

https://addons.mozilla.org/en-US/firefox/addon/youtube-all-html5

   It is also faster at rendering than Flash is.  Well at least
it corrects a lot of lag problems on You Tube (problem
may be You Tube, not Flash).

   Also, because iOS (iPhone, iPad, etc.) does not support Flash,
it seriously behooves your clients to switch to HTML5 (I do recommend
this to my clients).

-T

Todd,

These are not my clients (customers) in the for-profit business sense of 
the word.  These typically are colleagues who need Linux
support that the regular IT channels at my university will not provide:  
the IT unit only supports current MS Windows with their configuration
or, in so far as Apple supports it, Mac OS X.   Some of these 
colleagues, such as the one who raised this issue, is a retired faculty 
member who still serves as an editor on a major international social 
science journal.  I got sick and tired of trying to make MS Windows work 
on her machine, and got her to switch to EL .  Support problems vanished 
under EL -- and with Crossover to support the particular (obsolete) 
versions of the MS Office suite that she must use (I have attempted to 
get her to switch to Open/LibreOffice, but to no avail -- she also does 
not like the current MS Office suite user interface and typically will 
not use it although it is installed under MS Win under VirtualBox).  
However, the journal and some of her colleagues present material that 
requires Flash, and Flash is an accepted standard by her journal. 
Thus, I must support Flash format material.


Is there a mechanism to force Linux Firefox *NOT* to use the Firefox 
old and insecure database that Firefox uses for MS Win?  Although her 
current machine is X86-64, as with my own laptop, it is 
under-provisioned for a 64 bit environment.   It will run, but not well 
and may be unstable.  Understand that the above mentioned colleague will 
have ten or more GUI intensive applications open at the same time -- not 
just a word processor, a spreadsheet, and a web browser.  Hence I have 
left her at IA-32 SL6x.


Since my most recent posting on this matter, I have found:

How to Use VLC Instead of Flash Player in Firefox

VLC is an open-source cross-platform media player. It allows you to play 
standard video and audio formats from files on your computer, and also 
use the Firefox add-on to watch videos online through the browser. VLC's 
Firefox add-on uses fewer resources on the computer than Flash player 
does, so you can accomplish more while the video is running without 
programs having to stop or wait.



End quote.

Is anyone using Firefox on EL doing the above?  If so, how and does it 
provide the needed functionality?  Is the necessary software available 
from USA repositories or do intellectual property restrictions only 
allow it to be distributed, say, in the EU?


Thanks,

Yasha

It appears that the VLC route does not work.  Will VLC play Flash?  If 
so, does Firefox allow helper applications so that VLC would be used 
rather than a Firefox plugin?  This method -- helper applications -- 
used to work, but I have no details on the current implementations with 
regard to the allowed functionalities (e.g., MIME types) as permitted by 
either SL 6 or SL 7.  Presumably, Mozilla Seamonkey has the same issues 
as Firefox.


As for your PS question, a reply probably is more appropriate off-list.

I am in a similar, but not identical, situation.  I support a number of 
laptops with X86-64 processors that are running IA-32 mode environments 
(SL 6).  These need either to be replaced or to have increased 
provisioning (more RAM, larger capacity hard drives) to safely run a 
64-bit word length environment.   At the present, I do not have any 
grant funds that can be used for this purpose; to understand this 
situation, my university finds this a low priority; the priority of my 
university is to hire more administrators (and staff to support those 
administrators), and to engage in expensive eduspeak programs, whilst 
ever increasing class sizes and reducing real academic resources.

I was sad to learn that there will not be a 32 bit version of

screen displays.  However, my venerable laptops use 32 bit
processors.

I hope to have enough 3x4 goodness to last as long as I do, and
machines that will keep working for my wife (and her business) who
will likely outlive me.  However, Redhat stops providing security
support of the 6 series of distros after 2023.  I love the SL
community, and would love to keep upgrading SL distros forever,
and also keep using the old 32 bit machines, but it appears that
I must give up one or the other soon, or deal with some big
changes when I no longer have the ability to adapt to them.

Are there other distros with even longer LTS policies than SL and
RHEL?  Is there some way to keep supporting SL6x with security
updates long after RH stops providing them?  Some in our community
may have built measurement systems around 32 bit CPUs that must
keep collecting data far into the future - what is the plan?

Mate users list

[Yasha Karant]

Is there a users list (similar to this) for Mate, the Gnome 2 
environment for those who do not want Gnome 3 or KDE Plasma?  This could 
be an EPEL or other re-packaging/porting entity users list.

Hi,

I don't believe any Free/OSS/Community project has professional user
list(s). It defeats the point of Free/OSS/Community projects that help
and support each other as part of a whole, be that novice, intermediate
or professional. Having one core user list allows all to learn from each
other and spread the wealth of knowledge.

Regards

Phil



Phil.

Although there are many users on the SL list who are not computer 
science (informatics) professionals, there also are a significant number 
who are.  Much of the serious commentary is from professional users, not 
the typical banter one finds from enthusiasts attempting to get ubuntu 
installed to use an office suite application; and much of it is from the 
professionals who develop either SL (currently from the Red Hat 
subsidiary CentOS source) or who are familiar with the various 
application/environment/driver porting repositories for EL (such as 
EPEL).  I have not found the equivalent to the SL list for Mate, nor 
have I found such for the majority of end user enthusiast 
distributions.  This is what I mean by a professional list (similar 
lists exist for many environments and applications -- I can provide a 
set of these from my own experience, but the set by no means is meant to 
be exclusionary or complete).

Adobe Acroread linux current on SL 7

[Yasha Karant]

I fully understand that there are open source PDF readers.  I use a 
number of these, as well as Qoppa PDF Studio Pro (under license for fee) 
as a Linux replacement for Adobe Acrobat.  (PDF Studio Pro provides 
essentially all of the features I need that are provided by Adobe 
Acrobat -- and Adobe refuses to port Acrobat to linux.)


Nonetheless, I attempt to keep a functioning copy of Adobe Reader 
(acroread) on my workstation.  This was not an issue under EL 6. 
However, the most recent (last) Adobe Acroread rpm does not run.  I followed


http://www.if-not-true-then-false.com/2010/install-adobe-acrobat-pdf-reader-on-fedora-centos-red-hat-rhel/

3b. Install Adobe Reader (acroread) on CentOS/Red Hat (RHEL) 7
Note: On x86_64 bit system, 32-bit dependencies is also installed.

end quote.

With the IA-32 dependencies supposedly installed (yum install of the 
Adobe acroread RPM was successful), the application fails.


Does anyone have SL7 acroread working?  If so, how?

I really do not want to invoke Virtualbox to run MS Win 7 pro to run the 
MS Win version of acroread.

Assuming you have a license for MS Windows if one is required and 
enforced by your nation state (it is in the USA, EU, etc.), a very 
effective alternative is to load Oracle VirtualBox (licensed for free), 
load MS Windows under VirtualBox, and then install whatever MS Windows 
applications you need within MS Windows under VirtualBox.  Unlike Wine 
that has some issues with executing various MS Windows applications, if 
the application runs in the release of MS Windows you have, it will run 
under MS Windows under Virtual Box.

My amount of concern depends upon just what this infection can do -- 
including transmission of sensitive data and/or a root compromise.


From your response, are you assuming a separate stand alone hardware 
firewall that is filtering all traffic to the server, or an application 
running on the server?

If you are really worried about this put a web  application firewall

I would personally love to see an inline implementation of snort 
hooked into squid instead of iptables.

 The 'Penquin' Turla

 A Turla/Snake/Uroburos Malware for Linux
 By Kurt Baumgartner, Costin Raiu on December 8, 2014. 7:05 pm

 Recently, an interesting malicious sample was uploaded to a
 multi-scanner service. This immediately triggered our interest because
 it appears to represent a previously unknown piece of a larger puzzle.
 That puzzle is Turla, one of the most complex APTs in the world.

 We have written previously about the Turla APT with posts about their
 Epic Turla operations
 
http://securelist.com/analysis/publications/65545/the-epic-turla-operation/

 and Agent.btz inspiration
 
http://securelist.com/blog/virus-watch/58551/agent-btz-a-source-of-inspiration/ 
.
 So far, every single Turla sample we've encountered was designed for 
the

 Microsoft Windows family, 32 and 64 bit operating systems. The newly
 discovered Turla sample is unusual in the fact that it's the *first
 Turla sample targeting the Linux operating system* that we have 
discovered.


 This newly found Turla component supports Linux for broader system
 support at victim sites. The attack tool takes us further into the set
 alongside the Snake rootkit
 http://www.baesystems.com/what-we-do-rai/the-snake-campaign and
 components first associated with this actor a couple years ago. We
 suspect that this component was running for years at a victim site, but
 do not have concrete data to support that statement just yet.

 The Linux Turla module is a C/C++ executable statically linked against
 multiple libraries, greatly increasing its file size. It was 
stripped of

 symbol information, more likely intended to increase analysis effort
 than to decrease file size. Its functionality includes hidden network
 communications, arbitrary remote command execution, and remote
 management. Much of its code is based on public sources.

The 'Penquin' Turla

A Turla/Snake/Uroburos Malware for Linux
By Kurt Baumgartner, Costin Raiu on December 8, 2014. 7:05 pm

Recently, an interesting malicious sample was uploaded to a 
multi-scanner service. This immediately triggered our interest because 
it appears to represent a previously unknown piece of a larger puzzle. 
That puzzle is Turla, one of the most complex APTs in the world.


We have written previously about the Turla APT with posts about their 
Epic Turla operations 
http://securelist.com/analysis/publications/65545/the-epic-turla-operation/  
and Agent.btz inspiration 
http://securelist.com/blog/virus-watch/58551/agent-btz-a-source-of-inspiration/ . 
So far, every single Turla sample we've encountered was designed for the 
Microsoft Windows family, 32 and 64 bit operating systems. The newly 
discovered Turla sample is unusual in the fact that it's the *first 
Turla sample targeting the Linux operating system* that we have discovered.


This newly found Turla component supports Linux for broader system 
support at victim sites. The attack tool takes us further into the set 
alongside the Snake rootkit 
http://www.baesystems.com/what-we-do-rai/the-snake-campaign and 
components first associated with this actor a couple years ago. We 
suspect that this component was running for years at a victim site, but 
do not have concrete data to support that statement just yet.


The Linux Turla module is a C/C++ executable statically linked against 
multiple libraries, greatly increasing its file size. It was stripped of 
symbol information, more likely intended to increase analysis effort 
than to decrease file size. Its functionality includes hidden network 
communications, arbitrary remote command execution, and remote 
management. Much of its code is based on public sources.

   Functional description

The sample is a stealth backdoor based on the cd00r sources 
http://www.phenoelit.org/stuff/cd00r.c.


This Turla cd00r-based malware maintains stealth without requiring 
elevated privileges while running arbitrary remote commands. It can't be 
discovered via netstat, a commonly used administrative tool. It uses 
techniques that don't require root access, which allows it to be more 
freely run on more victim hosts. Even if a regular user with limited 
privileges launches it, it can continue to intercept incoming packets 
and run incoming commands on the system.



 Startup and Execution

To start execution, the process requires two parameters: ID (a numeric 
value used as a part of the magic packet for authentication) and an 
existing network interface name. The parameters can be inputted two 
different ways: from STDIN, or from dropper a launching the sample. This 
is NOT a command-line parameter, it's a real prompt asking the attacker 
user to provide the input parameters. After the ID and interface name 
are entered and the process launched

window switcher matrix in Mate versus Gnome 2

[Yasha Karant]

In the more recent updates to Gnome 2 under SL 6 (both X86-64 and 
IA-32), when one puts the pointing device pointer over an element of the 
window switcher matrix display, the actual primary applications running 
in the window/screen to which the element points are displayed.  This 
does not yet seem to be present in Mate as available for SL7.  Is there 
an addon that adds this functionality?

stereoscopic image viewer application

[Yasha Karant]

I have used sView in the past as a stereoscopic image view under X86-64 SL6.

http://www.sview.ru/en/

to build the RPM, the instructions I have read:

mv sview_12.05-1~precise.tar.gz 
$HOME/workspace/redhat/SOURCES/sview_12.05-1.tar.gz

rpmbuild -ba distribution/sView.rpm.spec

end quote.

Unfortunately, this seems to have run into a bit of a snag on SL7. Does 
anyone either have a current running version of sView or other 
stereoscopic viewer application(s) for SL7 that is recommended?

Hi,

Wow, the 'bit of a snag' being the mass of compiler errors emitted when
a build is attempted. This code in it's current condition will not build
on SL 7. You need to speak with the upstream developers of sview and
report the gcc 4.8 build issues with them.

Regards

Phil



Yes -- you observed the issue, and I strongly suspect that the upstream 
developers will not clean this up.


In the interim, as I mentioned above:

is there another stereoscopic viewer application(s) for SL7 that is 
recommended?


Thanks,

Yasha

processing system superior to LaTeX for producing journal articles and 
the equivalent, such as theses).



A build of TeXmacs from either source or the rpmbuild from a source rpm 
fails, and I do not have the personal spare time nor the personnel

GNU TeXmacs SL7 solved

[Yasha Karant]

TeXmacs-1.99.2-i386-pc-linux-gnu-B.tar.gz

from http://www.texmacs.org/tmweb/download/unix.en.html

using last stable works on SL7.  Note that  the web site states The 
binary distributions might not work on certain systems with old versions 
of Linux (from before 2009, approximatively) .  SL7 is more current 
than that.  One still must follow the INSTALL instructions after the 
tar.gz is unpacked.

Re: gnu texmacs, kile

Which SL 7 accepts which TUV Fedora release RPMS

[Yasha Karant]

Although I should have been able to find this information from a 
different source, via Wikipedia:

I found:

Fedora 19 → Red Hat Enterprise Linux 7


Is it correct that (most) binary x86-64 RPMs for TUV Fedora 19 will 
install on SL 7 ?

Two things, first is to try a slightly older version of BG to see if
that fixes your problem.

Second, the best alternative and cross platform is KompoZer (which is
what BG was built from).
   http://www.kompozer.net/

You'll find RPMs on their website too.


From the kompozer URL:

Latest stable version: 0.7.10 (2007-08-30)

This is a beta version (by release number, albeit stable by 
declaration) that is more than seven years old.
I have used kompozer in the past, but komopozer was not keeping up with 
some of the new features that appear in certain web pages.
As BlueGriffon uses the current Firefox internals, it more closely 
adapts to certain of these features as I recall from direct use.

Re: Mate 1.8

[Yasha Karant]

Problem solved.  Are the dconf-editor edited fields (variables) (well) 
documented anywhere?  I did a web search on this issue
and a found a reference that this had been solved in Mate 1.8 (at least 
on ubuntu).  As I show my research students, a MS Win 8, Mac OS X, Gnome 
3, or KDE Plasma interface is not as efficient as a Gnome 2 style 
interface for non-touch-screen machines; trackpads and touchscreens 
require ergonomic calibration that may be too sensitive for some 
hands/fingers.  Mate is much better.

Dell Latitude E6540

[Yasha Karant]

Is anyone running SL 7 on a Dell Latitude E6540?  My institution is 
considering this unit over the equivalent HP unit, to replace the five 
year old laptop that I currently use, because of the net lower cost of 
the Dell.  Dell claims that it will run Linux Ubuntu 12.04 -- but I do 
not know if this enthusiast Ubuntu has more secure boot, etc., 
capabilities than SL7x.


Any information, on or off list, greatly would be appreciated.

Since it's commercial software, maybe you could ask *them*?
I already have.  As Corel (which bought Bibble -- strange -- if 
corporations are people, and corporations can buy other corporations, 
why cannot non-incorporated real human people buy other non-incorporated 
real human people -- perhaps because corporations are not people but 
merely engines of avarice) effectively was bought by Microsoft a number 
of years ago, their technical support for Linux is not superb.  
Otherwise, Corel would keep (as does VirtualBox owned by Oracle, a 
parent corporation that competes with Red Hat for EL for-profit 
support) versions around that are in fact directly compatible with 
most distros. Interestingly, the IA-32 version (32 bit linux) runs fine 
under IA-32 SL 6x.


Speaking of which, is there any other workflow package that works as 
well or better directly under Linux (I do not mean Photoshop under MS 
Windows under VirtualBox under Linux -- I do mean native)?  I have tried 
gimp, but the import facilities for imaging vendor proprietary image 
formats (raw, e.g., Nikon NEF) is not as effective.  I do not run Mac 
OS X (a typical image manipulation environment) because none of our 
primary machines (both fixed workstations as well as laptops) are sold 
by Apple and thus it is software piracy in the USA to run Mac OS X on 
such machines (Apple will not sell a license for Mac OS X for non-Apple 
machines ) -- otherwise Mac OS X with fink or the equivalent might be a 
solution.

Microsoft Active Directory and SCCM

[Yasha Karant]

The administrative computing and network unit at my institution seem to 
want to force us to use Microsoft Active Directory and SCCM. The 
generalities that have been released to date are quoted below:


*Recommendation*

1.

   Work with the ITC’s across the University to join all University
   owned PC’s and Mac’s to an organizational unit (OU) of the CSUSB AD
   Domain.

2.

   Provide training to all ITC’s on Microsoft Active Directory and SCCM
   Administration

*Cost:* $25,000 Estimated

*Rationale:* With the availability of advanced tools to maintain and 
upgrade machines from a central console, Faculty and Staff will greatly 
benefit from patches and updates being done for them remotely and in an 
automated fashion. They will also be able to install campus licensed 
software themselves.


NB: ITC Information Technology Consultant (a California State University 
staff position designation) -- a technician, typically with a BS in IT 
or a related field, who has hardware and software control over 
non-administrative-computing Faculty MS Windows or Mac OS X workstations.


End quote.

Does anyone on the list have to use these Microsoft proprietary systems 
with EL open systems -- both servers and workstations? If so, what are 
your experiences and how does one do the integration? Under no 
circumstances are we willing to share root passwords with the 
administrative unit. Replies off list are welcome.
