Todd,

1) You asked for help and you are acting like a child demanding more
candy when you didn't get the flavor you wanted.
2) nmap is a very complicated swiss army knife tool. There are
hundreds of things it can do but you need to take some time to figure
them out and get what you want. Expecting that you will get the answer
handed to you is being unreasonable.
http://lmgtfy.com/?q=nmap+tutorial
3) what you are wanting is actually a multi step process. First you
need to see what mac addresses are on the network which usually only a
smart switch can tell you. You can sort of get the data with a
mac-ping but it isn't guarenteed to work. After you get all the mac
addresses on the network then you can work out what ip addresses or
hardware those mac addresses think they are. Again easier with a smart
switch.

It depends on what you are defining as an update because it means
different things. If you are talking about security updates and major
problem updates then it is sooner than 6 months.

You seem unfamiliar with how Scientific Linux ships software which is
causing you some confusion. Scientific Linux (SL) is built from the
git source code that Red Hat puts out for its Enterprise Linux (RHEL).
Red Hat does periodic updates to its software on a scale of 1 to 2
times a year but these upgrades may only backport fixes to the current
release number or may do a complete upgrade. [When a RHEL release
moves from various production stages which RHEL-6 just did, they only
backport major fixes.]

So if you need SL to ship samba4-4.2.12 then you need to check to see
if there are existing bugs on the issues you need fixed in
http://bugzilla.redhat.com and also test out whenever RHEL-6.9beta
comes out to see if the bug was backported to it. Otherwise you may
need to look at Scientific Linux 7 and if it is fixed/updated in SL7.3

That sounds more like a kernel problem with the hardware. The black
screen means that it is stuck in rhgb quiet mode to make it pretty but
is hiding quietly the real problem. In the grub2 edit of a boot line
remove rhgb and quiet and try a reboot again. It should stop at a
certain point which will help pinpoint the error. [My guess with the
T430 is that it is one of the BIOS update issues. It could also be a
problem with an nvidia extra chipset in some of the units when it is
in a docking unit.]

There are several caveats to that.
1) They only use it by default in certain filesystems and recommend
against it on others.
2) When they started the version they enable has a lot of "features"
turned off because they are not stable enough. So people were raving
about btfrs and then finding out that various things they were hoping
btrfs was doing wasn't on. This has changed over time so I don't know
the current feature set.

As far as I know.. they consider it "mature" for an even more limited

Two other tools which are useful:

1) Look through existing RPMs that match what you are doing. If you
have a bunch of perl or python or ruby looking at existing packages
can help you figure out why the guidelines and what you are trying
aren't working [because packaging is like cooking and sometimes you
need a LOT MORE SALT.. or none at all.]

2) Worse comes to worse.. there is easy-rpm. This is the I give up

NOTICE: python-six has been removed from EPEL as it is in EL6.7

[Stephen John Smoogen]

The package python-six is used as a shim for apps needing python3
command in python2 or python2 command in python3. The recent release
of Red Hat Enterprise Linux 6.7 brought the package into the 'base'
repositories which caused a conflict between the package inside of
EPEL and RHEL. When the CentOS-6 current release channels caught up
with the 6.7 packages, the package owner removed python-six from EPEL.

The problem is that people who are using other EL rebuilds or are
'using' an older release for various reasons no longer have access to
the package.

For people in this situation needing python-six still, the following
recommendations are possible:

0) If you are Red Hat Enterprise Linux customer, you should be able to
get the latest version from access.redhat.com.

1) Get the last koji build for EPEL in koji.
http://koji.fedoraproject.org/koji/buildinfo?buildID=549423

2) Get the CentOS package from a mirror (example:
http://mirrors.kernel.org/centos/6/os/x86_64/Packages/python-six-1.9.0-2.el6.noarch.rpm

3) Use your EL rebuilds various fast-track channels for access.

Then mirror this as a local repository for your users to have a yum repo for.

If you have neither (like this Thinkpad t540p) all you can do is plug

 You have a USB3 root hub, but whether you have working USB3 ports,
 it depends. Simplest is to look at mobo specs, the mobo
 info can usually be extracted from the output of dmidecode.

 Then you need to check possible errata - back in early USB2 days,
 mobos with some AMD chipsets had USB2 hardware that did not work.

 Now in early USB3 days I have some mobos that need special linux
 kernel command line switches to make USB2 work (or to make USB3 work,
 I forget which).

However there is hardware where the system has this on the motherboard

are labeled SuperSpeed (SS).  If those work then it is possible
(unless they have been wired into the USB-2 ports on the motherboard..
had to fix that on a system last month).

Finally if there is still doubt, check the BIOS of the system and if
it needs any updates. Various 'problems' with USB compatibility are
routinely 'fixed' by manufacturers after the system is shipped.

 I have looked at the OpenSUSE listserve more or less equivalent to this

In many cases OpenSUSE is going to be a lot like Fedora or non LTS Ubuntu.
It has shorter support times in comparison to SLED but gets updates to
various core materials much sooner. It uses RPM technology but was for the
longest time was more like slackware in how things were packaged up and
laid out on disks.

Usage of OpenSUSE in univerisity and research environments occurs mainly in
Europe with various places in the US using it (though the US universities
tend towards Debian.) YAST can be a wonder but it was getting a rewrite and
people who liked it in the past have been grumpy lately. However that is
most likely a temporary problem.

 I'm hunting for a way to re-enable the disabled SSL methods, but I'm not

 Hi,

 I have seen this once before with a persons system. The issue in that
 case was a bad physical connection. Removing the card, cleaning the
 connections and reseating the card corrected the issue.


Another place I have seen it is where the connector is bad. Sometimes it is
the motherboard and sometimes it is the video board. Works fine until the
system got warm and then it quit working. In the case of the video board it
was a simple replace and get working. In the case of the motherboard, it
was only found because the cards worked fine in other systems but not this
one.

Re: SL7: Missing texlive-* packages

 feedback on this?

 I'm essentially in your same position.  A few of my users I point to my
 Fedora box which has 'yum install texlive-scheme-full'.

 Where that didn't work well, for two users, I've copied a whole (44
 collections out of 45) portable install locally and update it with a cron
 job every weekend.  I drop to environment files into /etc/profile.d/ so it
 appears near the front of their PATH:

 == /etc/profile.d/texlive.csh ==
 set d=/local/texlive/2014/bin/x86_64-linux

 if ( ${path} !~ *$d* ) then
 set path = ( $d $path )
 endif

 == /etc/profile.d/texlive.sh ==
 d=/local/texlive/2014/bin/x86_64-linux
 [ -d $d ]  pathmunge $d
 unset d

 As I have my own local repo of packages, I'm *this close* to just
 packaging up that whole install (3.3 GB, texmf-dist/doc is 1.51 GB) into a
 single RPM (must be 4.0GB) and update/install that as needed.  I do this
 for matlab and a few others, just haven't gotten 'round to it yet.

 IMHO, it's insane/wasteful/slows down yum for Fedora to have over 2,700
 texlive packages installed.  And after a glance of yum logs, they've never
 updated just a few packages...


You should engage the texlive maintainers then to see how they can better
meet your needs. The issue was that they heard a lot from people who don't
want 4GB of tex. They want 10 mb of TeX for some documents in other builds
and other things. That tends to be the vocal users of TeX as they see TeX
needing to be installed on a buildroot because some Makefile is making a
ps/pdf/dvi file and pulls in TeX to do so.

 I started in this business in 1992 and our cluster of SGI machines
 was already based on NIS (from before my time). (I think
 automount/autofs/amd
 showed up a little later).


And I expect that you had at that point still stories from people saying
NIS broke everything when it went down and we should just use some homebrew
kit (or worse yet.. add each user by hand because lord how are you going to
know it got done.)


 But believe it or not, I am seriously considering going back to
 scp-pushed
 config files - too many technical problems have accumulated with NIS and
 with
 the current software chain nis maintainers-Fedora-RHEL-SL I doubt they
 will ever be fixed (even if nis maintainers still exist):


NIS has been dead upstream for 10+ years when Sun started pushing NIS+ and
then their own LDAP solution afterwords. A lot of large business/.gov/.mil
list it as verbotten because of the many security problems it has (password
issues usually though various hijacking items can occur). It is mostly
still in the distribution because people like us who became admins from
1987-1994 have it in our toolkit and know how to use it.

For the scp item.. you might want to look at ansible. It does orchestration
over ssh which allows for a lot of bypassing of these items.



- ypbind vanished mysteriously (usually during periods of network
 connectivity loss)
 - ypbind killed by OOM killer (kill something else, please!).
 - autofs and rpc.mountd doing negative caching (after pushing new autofs
 and netgroup maps,
   these demons have to be restarted on each client machine, or they would
 not see
   the added entries).
 - ypbind does not automatically open holes in the firewall (fixed in
 SL7?!?)
 - hard to add non-standard autofs maps (have to edit the Makefile).
 - probably more.

 
  My main concern is that most places I have seen that kept with ypbind get
  replaced with Active Directory (which FreeIPA is really trying to give an
  answer for).
 

 Not in the DAQ world - makes no sense to run a Windows Activer Directory
 box
 just to manage a bunch of (effectively) embedded Linux machines. Plus DAQ
 usually means unattended operation while Windows (and MacOS) has
 too many keyboard not found, please press F1 to continue gems and
 generally
 assume that there is a human lackey in front of the terminal at all times
 ready to service any whim (let's reboot now to install these important
 Windows updates!).


Not as much these days... if at all. I actually know some remote data
aqcuisition places converted over to windows only with it all automated. It
is mostly from 2012 onward, but it is catching up and we may end up
dinosaurs faster than we throught.

Hi

This is from memory so I may have missed some steps.

1) Use the rpm from Fedora 19
http://mirrors.kernel.org/fedora/releases/19/Everything/x86_64/os/Packages/f/fvwm-2.6.5-4.fc19.x86_64.rpm

2) At the gnome login it should bring up a choice of login as fvwm. Choose
that and it will set up the settings to default to that for the user from
then on.

 Only the servers are blocked from the internet since I figured they didn't

 In fact my internet connection is derived from a satellite connection which

 me from the rest of the world by nearly one second if it matters ...


Get yourself a little GPS gadget to lock into the satellite clocks on one

  No route to host for Samba I guess, I am accessing the server via ssh
 and that's how I gathered the data shown? As I said originally, I can't
 mount the samba share myshare from either Fedora-21 client. That began
 immediately after the system update, yum I presume? A notice popped up that
 there were updates that needed to be done and I simply told it to go ahead
 after I enabled it's WAN access.

 I don't think there's any difference between the yum and dnf updates any
 longer. When they first began testing dnf there were some differences, I no
 longer pay any attention to it, just do yum update with F-21 and assume the
 same for SL-7?

 Without WAN access I wonder how ntp keeps time, I assume it must get it
 from wherever it can find it on the LAN? The Fedora boxes have access and
 always have the correct time.



Does the problem go away with

yum downgrade samba

That should move you back to an alternate RPM of samba.

The ntp server needs to be able to talk to some server on the network to
get time. The Fedora boxes might just be 'lucky' in keeping time if they
have no access either.

ntpq -p on each of the hosts will see how they are keeping time.

 W3C non-compliant features introduced by a particular monopoly vendor in
 order to generate a captive market).


It wasn't ever really compliant.. mainly because W3C is a huge consortium
and there were different views for a long time about what was 'official'
[Those oligarch vendors are all members of the consortium for years.] I
think it was HTML 3 compliant and possibly HTML 4.0 compliant but after
that it was hit or miss depending on how strict you wanted to be.
