Re: MATE on SL 7

[James M. Pulver]

It'd also be nice to have a non GUI way to set the DE to launch, as with 
XFCE anyway I have to select for every user, can't seem to find anything 
to twiddle with puppet. Now, I'm not sure I want to enforce it either, 
but just change the default.

Thanks Bill!

You are absolutely correct. Switched back to GDM and the MATE selection
was exactly where you said it would be.

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 7.1.

Re: [SCIENTIFIC-LINUX-USERS] SL6 to SL7 transition guides?

[James M. Pulver]

Huh, I've found SL7 to be a very good desktop. Maybe I'm more willing to 
figure out how to install packages from other repos or from source (I 
did this once and am regretting it because now that I've found updates 
in EPEL I have to get the old version out of my homedir and 
/usr/local/bin ... and fix my desktop menu shortcut.


EPEL + nux(so glad I found nux) seem to have new versions of lots of the 
software I use on the desktop anyway...

I agree. As a small academic department we used to run SL6 on the desktop. We 
looked at 7 but it has the same problem as 6 of increasingly out of date 
packages. Now we use Fedora. Getting things to work the way we want is a 
challenge, the constant changes are a pain, but in return we get up to date 
everything with most user s/w requests coming straight from standard repos. We 
even run Fedora on four public facing servers so that everything is consistent.

On the server side we still very much use SL6 and are moving to SL7. With a 
minimal install (and sans Gnome which I don’t like at all) it’s a very nice 
system.

YMMV.

Can anyone provide me some assistance in how I ought to install cheetah to

Seems to be about it for the actual software. I've tried pointing at:

that munges the RPM installed cheetah for system python.


Any help would be appreciated.

Problem with GnuCash after recent Scientific Linux 7.1 updates

[James M. Pulver]

Every time I try and start it, I get

gnucash: symbol lookup error: /usr/lib64/libwebkitgtk-1.0.so.0: undefined 
symbol: _gst_tag_list_type


The GnuCash IRC helped me to figure out that it seems to be an issue with some

Any ideas how to resolve this? I've installed gnucash from EPEL-Testing now to 
get the latest version, but had this same problem with the version I had used 
successfully before from Nux.

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.

Thanks Akemi - i know. Thanks to a community of a bright and knowledge-sharing

But let's be blunt - it is not perfect, heck, it's not working correctly even

I think that if i had to (was forced to) buy new laptop for linux nowadays, i'd 
buy most probably something with Kaveri APU from AMD (like eg. HP EliteBook 745 
G2) .. Intel has good CPUs but bad VGAs and Optimus won't help you much, 
because it means you look at a bad pictures on screen most of the time (using 
Intel Vga).

AMD Kaveri APU has ofc worse CPU part compared to Intel APUs - but - do i need 
the CPU computing power here on laptop - no i dont, but do i need good sharp 
picture? Yes i need that one.
Why should i buy Optimus with Nvidia 1GB Ram card, which is used only 5% of 
time then and 95% time is used ugly Intel VGA?
Haha, i see it just as another clever plot to trick out us, poor users.


Anyway this became a bit offtopic, sorry for that :]]

Let me offer a suggestion that may help for production environments.
Use something like "rsnapshot" to make locked copies of an rsync mirror of 
Scientific Linux, and ensure that your local yum setup is aimed at a locked 
down version of the local repo whose contents have been evaluated. It takes 
thought and a configuraiton management tools like cfengine or puppet or chef, 
but it can be done.


Is this sort of thing where Katello is trying to make more dynamic or maybe

But you're always going to see things like this when a company is involved in

So the solution is anonymous donations of signed SRPMS in an automated fashion

Nico has a good point, and the only course of action is to make this absurd 
situation clear to the public. The only other two options are: 
paying and voiding you Red Hat contract or trusting Centos/infra/tooling.

If all this is done only to make RHEL and CentOS more compelling offerings

Sorry, my fault.  I subscribed to a few different lists which I thought would 
be interested in this, and then sent one mail which bcc'd them - assuming that 
the list servers in question would handle the rest.

Again, if you have any questions about this package set, I'd be delighted to 
answer them.  I've had a few come in so far, so I'll take the chance to 
summarise them here:

 - You can browse the list of packages here:

 http://pkgsrc.joyent.com/packages/Linux/el6/2014Q2/x86_64/All/

 - They aren't in RPM format, but pkgsrc (the system used to build
   them) does have pluggable backend support, and there was an
   unfinished GSOC project to implement RPM support a few years back.
   If someone is interested it would be fantastic to see this finished
   so we can provide them as RPMs via yum instead.

 - pkgsrc is branched every 3 months, and from that we generate the
   binary packages and provide a new package set, so every quarter
   there is a fresh update of new packages.

Cheers,

RE: ssh -X xinit failure

[James M. Pulver]

We're actually using X2Go - an OSS continuation of FreeNX as far as I can tell. 
No more going to nomachine.com at all - they have their own clients you can 
download etc. It works pretty well once you install the fonts manually into the 
embedded xserver or point to a local xserver with the fonts installed (this is 
on Windows. I think the other platforms already have the fonts)...

I tried XRDP here, and had nothing but weirdness, which is too bad as RDP 
wouldn't be a bad solution. But X2Go client is really slick - you can have it 
run a whole desktop, you can have it run a specific app, and you can have it 
use rdesktop to proxy an rdp connection to a Windows computer if you don't want 
to set up VPN or an RDP gateway server for that... I'm really impressed with 
the flexibility.

Also, once you get the client set up on Windows - you can easily zip the entire 
program files folder and then pass it around to run anywhere without 
installing, which is also nice!

Running this over ssh will most likely not work well at all.  If you want a 
remote desktop experience, look into nomachine or freenx:




Another alternative is to start Xvnc and tunnel the VNC port Xvnc establishes 
from your remote server via SSH.  Then use a local VNC client to connect to the 
same port.  This may work, but may also be worse than nomachine.

Using anything else, will most likely just cause grief and frustration.
 The X11 protocol isn't easily tunnelled, and requires quite some stable 
bandwidth to work decent.

Well frankly if you need PCI-DSS compliance pay for RHEL. Its honestly not that 
expensive for the few systems that really require it. Only  the system's that 
handle credit cards supposedly require it and in most ecommerce companies 
that's probably 2 to 4 system's so what's the problem wit paying $750 a year 
each for those few systems to not have to deal with the problems and giving the 
stock investors a warm and fuzzy feeling. Your time spent on it costs them more 
money and ti reduces all the stress on every one if you buy compliance on the 
cheap.

Shortly after our favorite upstream vendor publishes it? I don't see
the relevance though. If he needs to update CentOS 5, update it to SL
6 or CentOS 6. Why wait for RHE 7 to update? It's going to be major
cluster futz with the the switch tu systemd from init scripts, with
"/bin" being migrated to "/usr/bin", and the other major changes. It
will be much simpler, and much, much safer, to update to CentOS 6 or
SL 6 first!

RE: KVM live snapshotting

Whenever I tried to talk to the KVM IRC channel, I get told I need a much newer 
version than RedHat ships in EL and they don't support the old version in EL... 
So I wouldn't get my hopes up.

No offence, but maybe sending people to the right place is a good idea.
 SPICE is related to both KVM and QEMU, but it's still not the same
thing.  Same same but different, kind of.  So may I recommend one of
these lists instead?

* KVM mailing lists and IRC channels
http://www.linux-kvm.org/page/Lists%2C_IRC

* QEMU mailing lists

Yeah, I can understand that though ... asking about things in the wrong
list can also cause such issues.

AD Integration - what do you do about user/group pairs like puppet/puppet ?

[James M. Pulver]

So we're working along our SL6 and AD Server 2008R2 integration, using SSSD for 
authentication and such. We've realized that AD won't allow groups and users to 
have the same name. For common software like puppet and quemu that has this 
setup, what do you do? Change the program configuration to use a different 
group name? Do some hackery with OUs and sAMAccountNames and have it use gids 
(do the right things do this)? Technet says sAMAccountName must be unique and 
cannot be munged...

Greetings,

I have built many RAID systems using desktop disks and they are
generally quite stable. One of the issues with WD drives are with their
Green drives. By default, they park the heads after ~8 seconds of
inactivity. This will cause them to drop out of the array. The disk
firmware can be configured to disable this feature. I have had very good
luck with Samsung and Seagate drives. I have never spent the money on
Enterprise level drives.

BTW: The head parking feature is notoriously bad. If you calculate 1
park every 8 seconds. At constant usage, the drive will die in about 3
months. Perhaps this feature is fine for a desktop, but it is not for a
server or production environment.

Good luck,

RE: LTO tape drives

[James M Pulver]

We use LTO-5 with SL6 with no problems. We just told our vendor (IBM in this 
case) what drives we wanted to use, and they provided a server with the 
appropriate ports on the back. It's a basic SAS card as far as I can tell with 
external SAS connectors.

LTO-5 is definitely the way to go, you can use LTO-4 tapes which you can get 
cheap, or slightly more expensive (but coming down in price) LTO-5 tapes for 
more density.

Subject: LTO tape drives

Hi all,

I need some help and advice with LTO tape drives.  I haven't kept up with tape 
technology for several years now and from a quick google, it appears that the 
only games in town are LTO and DDS.  We do have a single DDS deployment and we 
are looking at replacing it with LTO because of capacity limitations.

Some questions:

(1) It appears that LTO-5 is the current technology. But most single drives use 
SAS as an interface.  Again, I am not familiar with SAS.  All I know is what 
the acronym stands for.  Is it a simple matter of buying a SAS card?  Will it 
run out of the box on a SL6.x box?  Any issues with drivers?

(2) I see that LTO-4 is still available.  And a quick google suggests that 
Ultra160 or 320 LVD SCSI is the more common interface for these drives.  I have 
several of the Adaptec 29xxx cards, made available when we transitioned to 
SATA.  Is this viable or would you recommend against using LTO-4?  It appears 
to be about 5 years old.  I think it would be preferable to use technology that 
has at least some life to it but I am not inclined to work very hard to make 
LTO-5 work if it is not well supported on Linux.

We are not looking to do anything fancy.  A single internal drive and a box of 
tapes.  Backups the old fashioned way.

Specific recommendations welcomed.  As in, buy this card, buy this drive!

Thanks!

Using sssd and kerberos to auth SL6.2 against AD (server 2008R2)

http://zews.org/rhel6-active-directory
which is actually working partially for me. I can log in (with some users

seem to get the groups. I have added (as listed in the example confs on that 
blog post) groups files sss
and even tried editing to
netgroup files sss
with no luck - it still seems to be using our old NIS to get groups.

Finally, finger seems to have cached information (we had %H/user) for home dir, 
that didn't work, changed to /home/user and then logins worked, but finger 
still shows the older entry...

Any ideas?

RE: CUPS doesn't offer Ledger as a paper size

Ok, so I realized that this worked ok for Windows 7 - XP apparently isn't using

So my next question is, can I just rename something in the PPD to Ledger? Maybe 
that will make it all work...

You should be able to modify the ppd file in /etc/cups/ppd/.  You can 
add/modify paper dimensions as needed there.  I'd start by cloning the 
Ledger entry, naming it Tabloid (or whatever), then adjusting the 
dimensions to the orientation you want.  Restart cups after editing.

LogMeIn also does this natively - it defaults to scaling the resolution so you

configuration of the local computer. You can also remotely match 
resolutions(i.e. temporarily set the remote computers resolution via LogMeIn to

There is a somewhat forgotten feature in X that allows you to set a 
virtual desktop resolution.  This allows you to run higher resolutions 
on lower res monitors.  It auto-scrolls when you hit the edge of the 
display so you have a sliding desktop feel.  Look into setting the 
"Virtual" attribute of the "Display" section of the xorg.conf for more 
info.  This way she can remain mobile with the laptop and save a few 
dollars on gadgets.

RE: LogMeIn

[James M Pulver]

We use LogMeIn (which pretty much always refers to the remote access product in 
my experience) quite a bit here at LEPP. It supports Windows and Mac OS X as 
"Hosts" or the computer to be remote controlled. It supports pretty much 
anything as "clients" or the computers from which you are sitting at to remote 
control the "host".

I've successfully used SL4 and 5 using Firefox and a JVM as stated to remote 
control Windows computers. I've also been able to use the Android client and 
have reports that the iOS client also works well. Of course you can also use 
Win and Mac as a client. The only missing thing is a "host" program for Linux, 
but in your case that isn't needed, the user doesn't want to remote control a 
linux OS.

On this topic, (but not directly answering this question) LogMeIn Free can be 
made pretty much user foolproof. A trick we use is one departmental LogMeIn 
account, and we use the "desktop shortcut" feature to hand out links that 
direct connect to one computer each. We embed the public ones on our Wiki or 
e-mail for desktop systems. The user clicks the link, gets the login screen for 
their computer and never has to access the LogMeIn account site.

If you get in contact with them they should be able to tell you which, but 
there will be no harm caused by a bit of trial and error to see which they have 
set up.

This is correct, and this is what I would check first as I think it is most 
likely..

This is also correct, you tunnel the remote control session over the Hamachi 
VPN.

RE: KVM virtualized Windows x64 machines crash

[James M Pulver]

I'm wondering if *anyone* is actually working on the GUI :p ... The suggestions 
from *this* list is to use something like OpenNebula or other third party

KVM on SL5 and 6

[James M Pulver]

I've been using KVM on SL5 for a year or two now, and so far found the guest 
performance great, but everything else about it barely ready for primetime. 
From the recent XEN postings re SL6, I found out that it may be because my only 
interaction with KVM has been through libvert and virt-manager.

Is there a better way to do things? Some of the main things missing in SL5 KVM 
via virt-manager are the ability to get decent screen resolutions (seem to be 
limited to about 1280x1024) and anything like VMWare snapshots.

We'd set up a test SL6 KVM host, and the screen resolution of guests seemed 
fixed, but I'm still disappointed at how undeveloped the KVM interface is 
compared to EVERY OTHER VM software I've ever used.

Pointers, or even just how you use KVM would be greatly appreciated. I honestly 
don't see how RedHat thinks they're competing with Hyper-V or VMWare with the 
offerings I've seen.

True.

And "Release" is usually perceived and understood as a version of
software with significant changes from the previous version. The new
schedule based approach is fine, but they should not be calling it
"releases". It's rather a regular builds that address bugs and add
some new features.

I'm not sure i understand the "marketing" behind this approach.

KVM on SL5.5 randomly pausing guests

[James M Pulver]

I've noticed on one of my servers that KVM is randomly pausing guests. I'm not 
sure why it's doing so, virt-manager gives me no real info. The two guests 
affected so far was a Windows 7 VM I was trying to install SP1 on and on the 
same host server a Server 2008 R2 guest that I wasn't interacting with at all.

Any ideas / troubleshooting?

RE: What kins of business use Linux?

[James M Pulver]

I suppose it's going to depend a LOT on the business, but I don't know of any 
"types of business" that would prefer Linux necessarily. Are you their primary 
IT support or a Consultant? If you're the primary IT guy for the small 
business, then like the above, if they need network storage etc, you could 
suggest / drop in Linux. If they need a basic mail server, drop in Linux. If 
they need a Kiosk, maybe drop in Linux. If they can get away from Office, drop 
in some Linux desktops.

If you're a consultant, it's probably going to depend a lot on the local IT 
staff. Can they support Linux? What tasks to they need to do?

In small business, I'd expect mostly Windows. Too many common apps are Windows 
only, like Quickbooks. And the vast majority of non tech people use Office.

I really don't like this kind of moaning. The moderator doesn't need any 
attitude adjustment, he is basically right. Despite the fact that SL5.x 
was updated the last year, it uses the code base, which more than six 
years old. This is FOSS, you get for free lot of software and if you are 
not happy with that you can invest your time and energy and contribute 
to the community.

While it is your right to dislike moaning, this is surely a valid complaint. At 
least for business use, you can't upgrade an OS every 6 months. Just like how 
Windows XP was supported longer than the few months after Vista came out, it 
would seem like a good idea to maintain compatibility with one OS version back 
(at least).

No. The number of users using SL5/CentOS5/TUV5 as a primary desktop is 
negligible, surely not millions, especially now when SL6/CentOS6 are out.

I can't comment on how many people use SL5 etc, but there isn't going to be any 
sort of quick upgrade to SL6 in any managed environment. So hopefully Firefox 3 
is supported for the next few years.

RE: forum for Scientific Linux users

I honestly prefer mailing lists or NNTP as forums each require a different 
place to go to see if there are updates, or else there's constant getting an 
e-mail notice, which doesn't actually let you know what was posted so then you 
have to click through, and log in to post a reply.

Even in the best case, like the Zenoss forums with a mail bridge, there's often 
buggyness or complexities that aren't needed with a mailing list or NNTP...

Using SAMBA to share CUPS printers to Windows 7 pushed via GPP

[James M Pulver]

I'm not really sure where the right place to ask this question as it touches on 
so many disparate technologies, but here goes. I'm trying to set up Windows 7 
clients to print to printers served from SL5.5 CUPS server using SAMBA to 
provide windows print sharing. We've got it working with the default CUPS 
postscript drivers, but it requires Admin on the Windows clients to install the 
driver.

So I want to manage this obviously and thought I could create a GPO using GPP 
Printer and set as a shared printer under the user part of the GPO. The problem 
is that it doesn't seem to work - I get various access denied. I expect this 
has something to do with even though SAMBA is joined to the same AD Domain as 
the Windows 7 clients, the machine accounts don't map to anything on the Linux 
side...

I'm mostly wondering if anyone is doing something like this, and how they got 
it to work - or if there's a better managed way to do this. I.E. do you have 
Linux print to a Windows Print server? Use scripts to push printers to Windows? 
Some other method I don't know?

I've been happy enough with nut monitoring APCs (over serial and USB), 
though at least when we started using nut there were no sl packages so we 
built our own based on Fedora srpms...  which was much less hassle than 
getting it to build on Solaris-8 :-)

Hey, Mr. James Pulver

I've been working with KVM for a while on SL5.5 for mostly Windows 
guests. Recently I've needed to run XP SP3 guests for legacy 
applications. However, when I set one up it maxes out the CPUs allocated 
to it, even when the guest CPU use is 2% or idle. Googling has only 
shown that it should support ACPI, which I checked and does have ACPI 
shown under computer in Device Manager of the XP guest.

Any ideas to get XP behaving as a guest with KVM?

Yes,

Set your guest system / XP vm in device manager to Standart PC  and not 
as "" uni prossessor / or Multi prossessor "" only if u use 1 VPU/CPU on 
your host system if u use 2 or CPU added to VM you may not set it 
standart PC.
