[CentOS] Curiosity Question

[Phil Savoie]

Hi All,

During updates I see a number preceding the package to be updated as 
indicated in the below example:

  1:perl-Module-Build-0.3500-119.el6_1.1.x86_64
  ^
Does anyone know what does this indicates?

Thank you,

Phil

It's the epoch, which is essentially a version override, i.e. any
version of a package with an epoch of 1 is more recent than a version
without an epoch (epoch = 0). It was conceived to overcome issues caused
by poor versioning.

For example
package-1beta-1
vs.
1:package-1-2

(1beta > 1, epoch to the rescue)

Leonard.

Which is of course no excuse for not even responding to a support
request. "It's not a bug, it's a feature" may not be the response the
client wants to hear, but it's much better than no response at all.

The most aggravating part of this is when my manager first set me the 
problem of trying to find a workaround, I *did* try async, and got no 
difference. Now, I can't replicate that... but the oldest version I have 
is still 6.2, and I think I was working under 6.0 or 6.1.

*After* I test further, I think it's up to my manager and our users to 
decide if it's worth it to go with less secure - this is a real issue, 
since some of their jobs run days, and one or two weeks, on an HBS* or a 
good sized cluster. (We're speaking of serious scientific computing here.)

[CentOS] Trying to find all the kernel modules needed for my machine using shell script

[Aft nix]

Hi,

I'm developing kernel modules right now, and the build times are
starting to get under my skin. As a side effect i'm taking way too
many "coffee" breaks during builds.

So i was looking for a way to build only the stuffs i need for my
platform. Chapter 7 and 8 of "linux kernel in a nutshell" gave a good
detail of how to do that by hand. Its a good read :
http://www.kroah.com/lkn/

But Although i understand the stuffs, this is still a lot of tweaks to
make that work.

2.6.32 and later kernels added a new target "make localmodconfig".
which scans through "lsmod" and change the .config appropriately. So i
thought i found my "automation". But this perl script has some problem
too.

This thread describes the problems :
https://bbs.archlinux.org/viewtopic.php?pid=845113

There was also a proposed solution which apparently worked for others
, is to run the script directly instead of using make's target.

Although for me, make localmodconfig does not work at all. its because
of the following :

$make clean
$make mrproper
$cp /boo/config-'uname -r' .config
$make localmodconfig

and it haults with

vboxguest config not found!!
nf_defrag_ipv6 config not found!!
vboxsf config not found!!
vboxvideo config not found!!

The thing is my kernel development environment is inside virtualbox.
These vbox modules were installed when i chose to install "virtualbox
guest addtion".

And the netfilter module might be a Distribution specific module(Lot
of netfilter modules are not part of the mainline kernel, so its not a
shock to me), which is not included in mainline kernel.

Now the workaround this obviously unloading these module and trying
again. But I'm thinking if there is patch for the
"streamline_config.pl" which will enable the user to exclude certain
modules if s/he wants. Problem is i have "zero" knowledge about perl
and i like it that way.

So my problems in "nutshell"

1) Patching streamline_config.pl so i can give a list of module name
as argument which it will exclude from processing the config file.

2) I've tried to run the script by myself. But running it directly
fails with a error.

[root@kernel-host-rh6 linux-2.6]# sh scripts/kconfig/streamline_config.pl
scripts/kconfig/streamline_config.pl: line 45: my: command not found
scripts/kconfig/streamline_config.pl: line 47: my: command not found
scripts/kconfig/streamline_config.pl: line 48: chomp: command not found
scripts/kconfig/streamline_config.pl: line 50: syntax error near
unexpected token `('
scripts/kconfig/streamline_config.pl: line 50: `my @searchconfigs = ('

Again my "zero" knowledge about perl does not helping my case.

Additional info:

I have faced the same thing in 2.6.32, 2.6.33, 2.6.35, 3.4, 3.4.rc1
.(I constantly switch version for various reasons, everywhere the
problem is same)

You can access the script from kernel.org gitweb:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=blob;f=scripts/kconfig/streamline_config.pl;h=bccf07ddd0b67a0e2f761fd5721f274a49bf9bbb;hb=HEAD

Its from 3.4.0. `git log --stat scripts/kconfig/streamline_config.pl`
shows some activity recently on this file. But my problem persists.

3) Is there any way i can get the "Centos specific" patches in "plain
patch" format? That means i dont wanna do things in src-rpm way.
If the patches are available in normal patch format i can keep
everything tidy in my kernel git tree.

You can ignore the "perl script" not running thing. I was trying
trying run a perl script with "sh" in front of it. How horribly dumb
i've been today :)

I always wondered why the default for nfs was ever sync in the first
place.  Why shouldn't it be the same as local use of the filesystem?
The few things that care should be doing fsync's at the right places
anyway.

The CentOS way of "Build Your Own Kernel Modules" is described in this
CentOS wiki article:

http://wiki.centos.org/HowTos/BuildingKernelModules

I suggest you try method 1 first to see if you can build your module.
Once confirmed, you may want to proceed to method 3 to build a
kABI-compatible module.

You can ask further questions about kmods either here, or better yet,
on the ELRepo's mailing list. ELRepo ( http://elrepo.org ) builds a
number of kernel modules for RHEL/CentOS/SL.

I'm using CentOS. But the problem was "make localmodconfig" is not
working. I don't see how a question related to "building kernel.org
kernel" relates to distribution, just because the problem was
discussed in a distribution's forum. Same kind of discussion can be
found(about faulty behaviour of "make localmodconfig") in
debian/ubuntu forums if use try google.

Not understanding how this relates to ignorance of "make". may be you
are pointing about the environment variables and stuffs.

I'm trying to tune up my kernel build. so i need to see which way it
performs the best. During development i dont "clean". I dont even make
the whole tree. i just build the part of the tree i'm developing.

Yep, i have run make menuconfig to see what's enabled. But you there
is thousands of options, its not practical to go through all of them.
I just see common options. Like if the driver for my ethernet card is
enabled "only". stuffs like that.

I managed to make it through without "perl" till now.

Honestly i've never checked it. i've just checked. nothing comes up
with --help, -h -?. All are unknown options.

English is not my native language. When i type quickly sometimes,
correcting all the spelling mistake seems like a burden. Sorry for the

So bottom line is, i can't get the patches other than src-rpms?


I better learn this thing, i guess.

That's why I mentioned yum update . Yum will get the dependencies
as well.

You're on CentOS and not using yum to update the system? You very much
need to learn it.

[CentOS] BCM4313 on CentOS 6.3

[ottop]

Hi all,

I'm a complete newbie in Linux and am trying to get my Broadcom BCM4313
working in my Lenovo S10-3t netbook (CentOS 6.3 installed from LiveCD).
I followed the steps in the wiki, which lead me to ELRepo: wl-kmod. I
followed the instructions there until Step 2:

$ mkdir -p ~/rpmbuild/{BUILD,RPMS,SPECS,SOURCES,SRPMS}
$ echo -e "%_topdir $(echo $HOME)/rpmbuild\n%dist .el$(lsb_release -s
-r|cut -d"." -f1).local" >> ~/.rpmmacros

Then I got stuck with this message:

bash: lsb_release: command not found

Next, I tried using the driver from Broadcom site, and ended up with this
message:

KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`

Trying to install something from another distro's always problematical,
given variances in numbering and dependencies. The "missing module
license" implies there's something not d/l, and if you'd been in a
debian/ubuntu system, and used apt-get, you'd have gotten it.

I did some googling, and found
.
Personally, since it's a system driver, I'd sudo -s, mkdir /usr/local/src,
and do the work in there. Other than than, and it's from this year, you
might have better results.

[CentOS] centos 5.5 yum updates

[pankaj.tolani]

This used to work for me last week

I basically need to install maven2 along with all its dependencies

So I follow the suggestions at
http://www.davehodgkinson.com/blog/2011/04/installing-maven-on-a-fresh-redhatcentos-5-5/


Now at the yum update step, I have started seeing lots of HTTP Error 404.
Have some of the repos moved?

I know a solution is yum clean all and then do yum update but then that
also updates firefox and xulrunner for me which screws up product I use.

Please tell me a way out. I dont want to do firefox/xulrunner upgrade, but
just maven2 installation as suggested on the page

thanks,
pankaj

I know how yum works. i'm a long time centos user. I'm talking about
the "centos specific patches" for the kernel. if i roll
these patches over vanilla kernel, it will become the kernel source
where kernel rpms are built. Now centos distributes its kernel sources
through src-rpms(srpms). Which is "already patched" kernel source.
What i want is just the patches. so i that i can roll it over vanilla
kernel
and get identical source as those distributed through srpms.

I hope i'm clear now.

cheers.

Are you referring to this ELRepo article?

http://elrepo.org/tiki/wl-kmod

It says, "yum install redhat-lsb". Also, if you follow the
instructions in there, you will NOT be building the module as root.
Mark has noted these points in his reply. So, please go through the
wiki carefully and try not to skip any steps.

Will you also show us the output returned by :

lspci -nn | grep -i net

I'd like to see the vendor:device pairing.

Afaik they are not CentOS specific patches. They are Red Hat patches 
(unless CentOS add additional patches).

Afaik you can't get the individual patches since that is not how Red Hat 
distributes their kernel src rpm which CentOS rebuilds. So you could ask 
Red Hat for the individual patches. Good luck with that. They started 
distributing pre-patched kernel sources to make competitors live (not 
necessarily CentOS) a bit more difficult. There's a long discussion 
about this on the Intertubes. Don't have the link anymore so Google is 
your friend.

If all else fails, you could do a diff between the vanilla kernel and 
the one distributed by Red Hat.

Patrick

I think these were the options that I was missing. I was able to create the
tunnel, and get my prompt back (so it will work within a script), without a
screen session. Thanks for this tip.

Trying to get this connection over ssh is just a short term solution. We
will be setting up a vpn tunnel between the systems in the near future (but
probably still 2-3 weeks out), but I was needing to get something else
running before then. The ssh solution works for the short term, until we
have an opportunity to get the vpn working.

Thanks to every one for the assistance with this issue.

As CentOS is essentially a rebuild of RHEL the SRPMs are mostly the same
as upstreams. Which sadly means that since v.6 the kernel source is
distributed as a pre patched tarball.

[CentOS] 70-persistent-net-rules

[Jerry Geis]

When my machine installs (CentOS 6.3) the two network cards are
getting reversed.   The PCI card is getting eth0 and the motherboard is 
getting eth1.
I would like them in reverse order to keep things the same as they used 
to be.

How can I easily tell these two to reverse?

Generate the 70-persistent-net-rules with motherboard eth0 first then 
the PCI slot?

Thanks,

Jerry

Edit the existing one? It does persist through reboots, which is what you
might expect from the name.

I'd like to automate- Editing is prone to  mistakes. Its not just one 
machine.

So I'd like to automate it.

In that, I edit the 70-persistent-net-rules file, but now I just remove
it. In short;

1. Stop networking
2. move HWADDR value between ifcfg-ethX files.
3. Delete 70-persistent-net-rules
4. Run; 'start_udev'
5. Start networking.

That's a lot more complicated, since each have their own MACs. Do you have
a) some kind of centrally-controlled configuration, and b) are they all
under DHCP, and only allow known MAC addresses to get IPs? If yes to both
of those, you could write a script to make it, using those, and push it
out.

On the other hand, you only need to do it once for each machine.

I don't think you can always count on the detection order - so blindly
automating a swap is probably a bad idea.  Also, you are going to need
the right MAC addresses in your ifcfg-eth? files to keep them nailed
down.

'lsof' should tell you what has the device open.

That's true, but I'm guessing that a lot of people on this list are here 
specifically because they're not paying for support.

Whether that's true or not, if you're deploying virtualization *on 
CentOS*, KVM is really the only rational choice.  Xen hosting support is 
no longer a part of new releases.

Not off hand, but you could help by posting the configuration file 
containing your rules instead of a vague description of it.  There's not 
really enough to go on yet.

Rules dropping outbound traffic on the un-numbered interface are 
extraneous.  If the kernel doesn't have an address on that interface, it 
won't have any routes assigned to that interface either.  Hence, no 
traffic will be directed out of the un-numbered interface.  If you list 
your rules with "iptables -L -v" you'll see the packet counter on that 
rule has 0 hits, because it's never used.

This might not help though if there are kpartx maps linked to that volume.
In that case you can use "dmsetup ls --tree" to see if that is the case.

It's not available in any centos repo. Red Hat doesn't update the
version of anything in Enterprise Linux, beyond bug and security fixes.
CentOS being binary compatible follows the same rules.

If you want python 2.7 you will need to find a 3rd party repo or install
from source.
