To me "not supported" means the KDE packages (and all dependency libs)
will not be in the official repos. So have fun trying to build all
that yourself. Most likely there will be a third party unofficial repo
that will have those KDE packages.

BTW I think the new KDE Plasma desktop on Kubuntu 18.04 is fantastic.
Way more modern and polished than the old KDE days. Especially with
the alternative fullscreen dashboard application launcher. It's my
preferred desktop choice out of gnome3, mate, and xfce.

Re: [CentOS] /lib/firmware/microcode.dat update on CentOS 6

[Robert Arkiletian]

There is a new guidance document from Intel here

https://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf

Changes since the previous release are highlighted in yellow.
Unfortunately, the latest microcode here

https://downloadcenter.intel.com/download/27591/Linux-Processor-Microcode-Data-File?product=873

does not seem to contain all the yellow updates (at least for my
hardware). The document is from April 2 and the latest microcode
update is from March 12.

[CentOS] C6 KPTI cpuinfo flag?

[Robert Arkiletian]

Noticed C6 had a kernel update on Friday.
2.6.32-696.18.7.el6.x86_64
What is the flag in /proc/cpuinfo that indicates the KPTI patch for
Meltdown CVE-2017-5754 for C6?

Some distros are using "kaiser" some like Fedora are using "pti". Also
noticed some (like Fedora) are displaying "cpu_insecure" under the
bugs: heading of cpuinfo.

[CentOS] C6 Firefox 45.1 segmentation faults

[Robert Arkiletian]

on updated C6 x86_64 Firefox ESR 45.1.0 is seg faulting on various sites,
mainly media sites. Tried uninstalling flash-plugin 11.2.202.616 but
problem persists.

Work around: installed Seamonkey from epel repo

Anyone else experiencing unstable behaviour of FF 45.1 on C6?

[CentOS] verify clean umount

[Robert Arkiletian]

This is on a C6 systems.

How can I verify that an ext4 data partition is being unmounted properly at
(reboot/shutdown) on a sysV init system. I've looked at S01reboot and
S01halt scripts in etc but what I'm concerned about is that I mounted my
partition on a tmpfs dir mount point. So if those S01 scripts try to umount
the tmpfs dir first they may get a "target busy" and then they will try a
force umount. (I think that's not good)

Basically I'm trying to verify that the partition (on reboot/shutdown) is
being unmounted before its tmpfs mount point. Is there an easy way to
verify this?

This makes sense as I remember reading the latest versions of Firefox
supporting gstreamer1 not 0.10. That's probably why gstreamer1-libav works
with Firefox 40.

Re: [CentOS] C6 firefox esr h.264 support on youtube

I had already looked at the nux repo. They may have that package for C7 but
I can't see it for C6.

I'm thinking h.264 gstreamer support must be provided by another package in
C6.

I have gstreamer-plugins-base & good installed. And I've already tried ugly
and gstreamer-ffmpeg.

I too noticed that HGST (now owned by WD) makes native 512n drives. That

512n). But there are almost no reviews on these HGST native 512n drives

 4Kn drives are appearing now also. I don't expect these drives to be
 bootable except possibly by systems with UEFI firmware. It's also
 possible hardware RAID will reject them unless explicitly supported.

 The emulation implementations don't come into play if the alignment is
 correct from the start. The better implementations have significantly
 less pathological behavior if alignment is wrong, but that's
 anecdotal, I don't have any empirical data available. But I'd say in
 any case you want it properly aligned.


According to this pdf [1] alignment is important but from what I understand
512e emulation still has a small RMW performance hit from writes that are
smaller than 4k or if the writes are not a multiple of 4k.

Also it's probably not a good idea to mix 512e with 512n in a raid set.
Although this may be hard to avoid as drives fail in the future.

 If I could build it, I would.  At the present time, i can not build it
 as the source is not on ftp.redhat.com or git.centos.org.

 Red Hat does not have permission for it to be built anywhere besides
 their supplemental channel for RHEL6, and I have asked Red Hat legal and
 they are trying to get permission from Google to release it in CentOS.

 I am sorry, but I can't build and release it at this time.  I may not be

Correct. Chromium no longer supports NPAPI Netscape Plugin API.

So the older 11.2.x  version, which btw has no more development from Adobe
other than security fixes, works with Firefox only.

The newer 15.x version pepper based flash works with Chromium. But, as far
as my understanding goes, that plugin can only be distributed by Google.

  The .spec file for chromium-browser does have conditionals in it, such
 as:
 
  %define flash 0
 
  Looks like pepperflash is added from google-chrome-stable if flash is
  defined...

 OK new version posted.

 This uses the centos-6 testing key and is available here:

 http://people.centos.org/hughesjr/chromium/6/

 The repo file is here:

 http://people.centos.org/hughesjr/chromium/6/chromium-el6.repo

 This version is now called chromium-browser and not chromium, so if you
 have the older version, you will need to:

 yum remove chromium

 then

 yum install chromium-browser

 Later updates should happen with yum update and the name chromium-browser

 python 3.3 is available in software collections [1].
 Works quite well, is easy enough to use.
 If you absolutely must have python 3.4, I don't know.

 asyncio for python33 is available on pypi [2].
 Don't know if this is exactly compatible with 3.4 though.

 [2] https://pypi.python.org/pypi/asyncio

Thank you Elias,

SCL worked perfectly. Installed Python 3.3 then installed the asyncio
module from pypi. I was a little afraid about where the module would
be installed but it was smart enough. I simply scl enable python33
bash *before* building/installing the module. Now I can show my
students the very latest in asynchronous network programming.

Software Collections is a great idea. It really addresses and solves
one of the biggest issues of rhel/centos.

[CentOS] Need Python3 for C6

[Robert Arkiletian]

I need Python 3.4 (latest) on CentOS 6 for development purposes
(teaching programming).

Need advice for best method to do this. I am concerned about not
breaking the internal plumbing of C6. I was thinking about installing
it into /opt.

I noticed  http://puias.math.ias.edu/data/puias/computational  has 3.3
but I need 3.4 (asyncio module). Wondering if anyone has tried python3
from puias repo ? Does it break anything?

Also, found http://toomuchdata.com/2014/02/16/how-to-install-python-on-centos/

Any advice welcome.

if you include libcrypto in the grep then sshd is affected.

 different. Currently the systems are running Windows (but this may change). 
 Most
 days the systems are hacked by the kids and all is well, but sometimes the
 changes to the systems requires a reinstall. The staff are not presently

 Here is the draft idea:

 1. Have a CentOS image / PXE server.

 2. Make a (bootable) utility CD that:
 * has a program to save the state of the computer to the image server
 * on boot gives an option to re-image the computer
 * has a (boot-time or OS) diagnostic program to check network connectivity to
 the image server

 3. Make a single page instruction sheet on using the utility disc, including 
 on
 how to boot from CD

 Implementation suggestions?

Don't re-invent the wheel. DRBL/Clonezilla already has everything you need.

 That's unfortunate.  :(  Is the bug in libssl, libcrypto, or both?

 Since sshd is in doubt, I would like to force my users to change their
 password, which is stored on a central openldap server.  What's the
 canonical CentOS way to do this?  I've done some web searches for some
 answers, but haven't found anything really definitive, just some
 workarounds and some crude hacks.


I'm not positive but from reading other forums it seems sshd is *not* affected.

http://security.stackexchange.com/questions/55076/what-should-a-website-operator-do-about-the-heartbleed-openssl-exploit
snip---
It's worth pointing out that OpenSSH is not affected by the OpenSSL
bug. While OpenSSH does use openssl for some key-generation functions,
it does not use the TLS protocol (and in particular the TLS heartbeat
extension that heartbleed attacks). So there is no need to worry about
SSH being compromised, though it is still a good idea to update
openssl to 1.0.1g or 1.0.2-beta2 (but you don't have to worry about
replacing SSH keypairs).

Re: [CentOS] And then there was one (browser)

[Robert Arkiletian]

Sorry for this being off topic but I feel it emphasizes the need for
long term support for desktop browsers on Linux.

Went hunting for any info on Opera for Linux. My assumptions seem to
be correct about Opera.  I have no proof this is a legit post but it
sounds like the truth:


At my previous employer, a small browser vendor that decided to
abandon its own rendering engine and browser stack, I stopped using
our product because Linux wasn't a priority. Numerous reasons were
given, such as low market share, only geeks use it, all journalists
use Macs, c.

This was to the point of ridiculing the platform and the people
working on it, frequently citing Linux jokes such as you'll
probably have to recompile your kernel first whenever the question
was seriously raised about when we'd start at least getting the core
libraries working.

And when I say it wasn't a priority, I mean that we didn't even have
something that was in a compilable state. A few people had started
fixing up the broken code to get something that would compile on Linux
in their own free time. After a few weeks of hacking, they were told
by management to stop what they were doing and instead focus their
volunteer efforts on the project goals, being to ship a Windows and
Mac version.

So the company began the process of forcefully moving developers who'd
worked on Linux for over 15 years to platforms they felt uncomfortable
and unproductive working on.

This is a much longer tale, but it tells the story of a company
alienating not only their loyal user base, but also a significant
proportion of their own developers. The result? Lack of motivation and
resignations.

Well done.

[CentOS] And then there was one (browser)

[Robert Arkiletian]

About 6 months has passed since the last working version of Opera
(12.16) for Linux was released. Opera 18 (Win+Mac only) is now based
on Chromium so I'm not holding my breath for it to work with C6 even
if it is ever released.

Chrome/Chromium is pretty much history too (libs too old). So Firefox
is the only game in town. Even lesser knowns like Midori won't work
either. Considering the amount of time left in the C6 support cycle,
one would have thought TUV would have worked with Google to find a
solution but I haven't heard a peep.

How can XP, an ancient OS going EOL in a few months, still be
supported for the latest Chromium but C6 not?

Does anyone know of secret plans to eventually support Chrome/Chromium
on C6? (crossing fingers)

Title says is all. Nice to know RH understands and accepts the

Although it is complex. After all, if too many choose CentOS, there
may no longer be a CentOS. However, I don't think I would refer to
CentOS as a parasite as the author Matt Asay does. More appropriate
to call it symbiotic.

 I will be glad to build it, *IF* I can reproduce what the script does

 SRPM for everything we release.

 The problem is, if he is not going to support it later, his gcc patches
 may not keep working on newer code and we only gain a couple of builds
 and run out of support.

 Since I personally use chrome as my browser (and obviously CentOS-6.4 as

 It would not be 'backporting' if you'd set up a build environment that uses
 a newer GCC and GTK2 library, and statically link against the newer GTK2.
 That's a bit of a pain for release engineering, but it's not rocket
 science. RHEL6/C6 (and Ubuntu 10.04) desktops are probably a tiny fraction
 of Google's user base, so they just may not want to expend the effort.

 Alternatively, one could do something tricky like make a special build of
 newer GTK2 libraries built with the newer GCC, and make Chrome load them in
 stead of the regular ones.

 Well, there are hobby users and there are real users.  Google SHOULD
 understand the difference.

 Most businesses and large user deployments of a Linux desktop would be
 using things like CentOS, RHEL, SLES, Ubuntu LTS and not the bleeding
 edge distros with all the new versions of GTK.

 Don't get me wrong, I understand that there are a large number of people
 using the 6 month distros too ... BUT ... most enterprises I know of
 that use Linux on the desktop are not among them.

 Mozilla did figure that out and release their ESR version for these
 people because they understand that they do make up a significant
 portion of the people who actually get work done on Linux.  Hopefully RH
 will be able to convince them to continue to provide some kind of support.

 Not 100% this is true but the problem apparently is that rhel6 uses an
 old version of gtk2.

Update, I just read the issue is also C++11 and gcc 4.6. Apparently,
Chromium devs prefer to use the newer c++ standard and that breaks the
toolchain on older distros. I think C6 uses gcc 4.4.6.

Also rumor is Google and Red Hat are now talking about this issue. I

[CentOS] UPS issues with PFC PSU

[Robert Arkiletian]

Just noticed that our new server has a newer 80+ efficiency 865W PSU
with PFC. So apparenty our existing 1500VA (865W) APC Back-UPS is not
safe to use anymore. We apparently need a pure sine wave UPS.

http://nam-en.apc.com/app/answers/detail/a_id/8883

I found an affordable 1500VA UPS by CyberPower,  model CP1500PFCLCD,
which has a pure sine wave output.
Wondering if anyone has experience with CyberPower UPS's. Are they any
good?  Any problems with pwrstatd ?

I've seen many threads about hardware recommendations as there are
many sys admins on this list. It IS for a CentOS box if that makes it
more on topic. Maybe I should have put an 'OT' in front of the
subject.

Anyway, have you anything experience with CyberPower UPS's?

Sorry I should have initially stated it was for CentOS6.



 well, where else would he connect the UPS to? His fish tank?
 Surely if someone has a PC, and is subscribed to a Linux mailing linux
 and asks for advice on a hardware device then it would be related to
 compatibility as well.


Thanks for the support but I really don't want my query to turn into a
debate about what's off topic. It's just that I have only ever used
APC and apcupsd. I've never used CyberPower and wondered if other
CentOS people were using it with success/reliability. If that's off
topic then I've learned something.

[CentOS] Determine high i/o reads/write directories

[Robert Arkiletian]

I have a DRBL server, basically an nfs fileserver, which I am
rebuilding. I want to put the high i/o directories on a separate raid
array for performance. Currently everything is under / in one raid
array.

How can I tell which directories, obviously other than /home, are
getting high reads and/or writes? Any tools to measure i/o per
directory?

Thanks

[CentOS] centos6 filesystem size limit

[Robert Arkiletian]

I just read the rhel6 filesystem size limit.

http://www.redhat.com/rhel/compare/

It says 16TB limit for ext4 (same as ext3)?!?!  I thought ext4 was
supposed to support 1EB ( ~ 1 million TB) limit. That was one of the
main advantages of rhel6. After a little more digging all I found was
that the user space formatting tools (mkfs.ext4) only support 32bit
filesystems (not 48bits). I'm surprised about this, I thought people
would be waiting for 16TB support in rhel6. Does anyone know if this
is going to change in point releases of rhel/centos6?

Happy New Year

[CentOS] Resize all partitions bigger

[Robert Arkiletian]

I effectively have 1 drive /dev/sda  (it's actually a hardware raid 10 array)

I have lots of free sapce. I want to resize my partitions (boot, home,
/) bigger.
Going to use Clonezilla to make an image of each partition and save it
on another box.

Then re-partition and format new bigger partitions.
Then restore images with Clonezilla.

But I know UUID's will be wrong and I don't feel like creating new
ones. I just want to use /dev/sdx

Am I correct in assuming I only need to edit /etc/fstab and /etc/grub.conf
or is there anything else I need to edit?

 You might be better off using dump(8) and restore(8) to copy and
 restore the disk partitions.   Dump will preserve the information
 you need and then restore will allow it to use the new larget
 partition cleanly.    Some of your other cloning software (I don't
 know about Clonezilla) including dd(1) will try to duplicate the
 space as it was on the old partitions and not use the new space.
 So dump the partitions
   redo the partitions
   restore in to the new partitions
 If you are changing root (/) and/or /boot you have to build a minimal
 bootable system on it/them.   But, really root and /boot do not need
 to be very large if you put growing stuff in its own partitions
 such as /home, /usr, /var.


Thanks for the advice. My initial question remains.

Am I correct in assuming I only need to edit /etc/fstab and /etc/grub.conf
to boot from the new partitions?

[CentOS] Dual personality Server (network pass through)

[Robert Arkiletian]

I have 3 nics in a NATed gateway file server. Two nics (eth1, eth2)
provide dhcp and nfs services to an internal subnet via a dedicated
switch. The other nic (eth0) connects to an external WAN switch to
provide net access to the systems in the subnet.

   --- eth1
WAN switch eth0 --- |   SUBNET switch
   --- eth2

Question:
Is it possible to disable the NATing, nfs, dhcp and just somehow
bridge the external WAN nic to the internal ones such that it's just a
pass through? Basically having the server behave like a switch?
Allowing the internal systems to join the network on the WAN. I know
how to disable NAT, nfs and dhcp but not how to configure the nics.

I know I could simply unplug eth1, eth2 from the server and plug them
into the WAN switch but my goal is to script this so I don't have to
physically plug and unplug network cables each time.

Thanks

 You do this by creating a bridge.

 The Red Hat/CentOS way is to create emptyish interface files like:

 # cat /etc/sysconfig/network-scripts/ifcfg-eth0
 DEVICE=eth0
 BOOTPROTO=none
 BRIDGE=br0
 ONBOOT=YES

 # cat /etc/sysconfig/network-scripts/ifcfg-eth1
 DEVICE=eth1
 BOOTPROTO=none
 BRIDGE=br0
 ONBOOT=YES

 And then a bridge interface file:

 # cat /etc/sysconfig/network-scripts/ifcfg-br0
 DEVICE=br0
 TYPE=Bridge
 ONBOOT=yes
 STP=on
 IPADDR=system.ip.address.here
 NETMASK=your.dotted.quad.mask

 Obviously, adjust as needed to match your actual hardware, etc.

 This can of course also be scripted using the actual networking commands,
 that I don't recall offhand.

Ah, Thanks Alan.  I can write the script from this point. :-)

Re: [CentOS] question about software Raid 1

 Does software raid 1 compare checksums or otherwise verify that the same
 bits are coming from both disks during reads?  What I'm interested in,

No. Reads are distributed over disks to increase performance.

 is whether bit errors that were somehow undetected by the hardware would
 be detected by the raid 1 software.

Depends on the type of error. However, the sad thing is, if you use 3
disks for raid 1 the kernel does not do the right thing. Let me
explain.

Say you have 3 disks in a raid 1 array. If there is a mismatch then
the smart thing to do would be to take a vote of the 3 disks. 2 out of
3 wins (assuming they are not all different). The odd man out should
be corrected (if possible). But what actually happens is the highest
numbered disk is copied to the others.

I haven't looked at the latest kernel code but if this
http://linas.org/linux/raid.html
is correct then I think the kernel maintainers should address this
issue. I don't think it would be hard to implement.

Hopefully you have a redundant PS unit. Having a UPS is not going to
help if your PS fails.

 I could be tired, but could you please elaborate how this is possible?

mv CentOS-5.0-i386-bin-DVD.iso CentOS-5.1-i386-bin-DVD.iso

Check out the public mirrors list. Only mirrors that offer full DVD
downloads and rsync will work. Hover your mouse over the rsync link to
see the rsync address.

For example, if I was to use the kernel.org mirror it's
rsync://mirrors.kernel.org/centos

then navigate the http or ftp directory structure to see the full path
to the iso. Then run rsync

rsync -Pv 
rsync://mirrors.kernel.org/centos/5.1/isos/i386/CentOS-5.1-i386-bin-DVD.iso
.

You should get upto 50% savings. At least I did with the CD iso's in
the past. The capital P is --partial --progress.

  Why use torrents? With torrents I get around 25Kb/sec.

 Sounds like something is throttling your torrent connection. Start by using
 a non-standard torrent port to escape traffic shaping by naive throttles.

I think the EFF was accusing Comcast of doing this.

  With places such as utah.edu [I am in North America] I got
  320Kb/sec steady. It took me 3hr and a bit to download the 5.1
  dvd. As far as I understand it, Utah and the other mirrors donated
  the bandwidth to the community.

 Torrents have the benefit of sharing the cost over many community
 contributors.


Also don't forget that many mirrors offer rsync. If you rename your
5.0 DVD to the 5.1 version and do an rsync it will save lots of
bandwidth.
