Hi Gordon,
Your assumption turned to be true : - (. The file was corrupt (file ...
gave "data" as type, rpm -Vf throwed tons of "missing" errors). After doing
this and trying not to load the module I lost the contact to the server so
my provider had to fsck it; now the server is up again, I still have to
re-check everything.
Thanks for your help,
Jesus

[CentOS] Centos 5.8 has no "Virtualization" install option

[Dennis Jacobfeuerborn]

Hi,
when I try to install Centos 5.8 on a Dell r410 then I don't get a
"Virtualization" option during the package selection of the installer.
Centos 5.7 does show that option fine. Is this a known issue?

Thanks for the explanation. Please help me understand when i install CentOS
5.8 on a fresh server, what are the available repositories by default and
if i need any packages which are not there in the default repos, Do i need
to enable third party repositories.

Yes, flash player appears to have some nasty bits - maybe this is 
another reason why Apple / Steve Jobs was so anti flash on the iPhone.
I am now using Konqueror with flowplayer - this is a java / flash 
incarnation that seems to work fine.

Windows only authenticates CIFS with Kerberos, NTLM or plain text AFAIK.

If security is a concern this means you'll need a Kerberos system or SAM 
account database setup.

Kerberos is probably not an option at this point, which just leaves a SAM 
database of NTLM passwords.

For this scenario the database comes in two varieties (backends), openldap or 
passdb.

Openldap requires you to add the samba schema to your database and go through a 
period where it synchronizes the SAM passwords, basically implicitly trusting 
the client and recording the password sent to it if the password in the SAM DB 
is blank, if it isn't blank then authenticating the client.

Passdb is pretty much the same except the SAM database is kept externally so no 
need to change your openldap schema.

I do believe there is a way to use Samba+PAM to keep the passdb synchronized 
with the openldap by doing a samba password change whenever an openldap 
password change occurs, but it's pretty fragile.

Personally I always prefer Kerberos, but it can be a bitch to setup after the 
fact (all those UPNs and SPNs plus nodes and applications = pain).

Based on your errors, what I would do is this:

1.   You only need 1 version of glibc-common.x86_64.  The only way you
could have gotten into this position is either your machine died in the
middle of a yum update or someone force installed the later glibc-common
via the rpm -i command.

I would first try to install the yum-utils package with this command:

yum install yum-utils

once that is installed, I would try:

yum-complete-transaction

If you do not have any incomplete transactions, then you have some bad
packages force installed.

I would figure out exactly what packages I had installed for glibc and
get them all on one version ... you need to be careful with glibc (and
its sub packages) ... it is the most important package on your machine.

How I would do this is that I would download all the RPMs for the latest
version of all the packages you have installed ... for me that would be:

glibc-devel-2.12-1.47.el6_2.12.x86_64.rpm
glibc-headers-2.12-1.47.el6_2.12.x86_64.rpm
glibc-2.12-1.47.el6_2.12.i686.rpm
glibc-common-2.12-1.47.el6_2.12.x86_64.rpm
glibc-2.12-1.47.el6_2.12.x86_64.rpm
nscd-2.12-1.47.el6_2.12.x86_64.rpm

You may have others.

Once I had them all in the same directory, I would try a:

rpm -Uvh *.rpm

then I would look at the errors

based on those errors (if it does not install) then I would likely do:

rpm -Uvh --force *.rpm

that will LIKELY clean up your rpm issues for glibc ... but if you don't
understand the errors, post those here.

2.  For bash, I would:

rpm -e  bash-4.1.2-8.el6.centos.x86_64

then I would reinstall the other bash

yum reinstall bash-4.1.2-9.el6_2.x86_64

3.  The real issue here is to make sure you figure out HOW you got in
this position and how NOT to get into it again.

Thank you very much for your response.

But I'm afraid I'm not clear what action I can take.
I don't like to remove any glibc or glibc-common packages,
as I'm afraid it might have a disastrous effect,
since they seem to be required by so many other packages,
including the kernel.

I'm slightly puzzled how the system got in this position,
as I have never said anything except "yum upgrade",
and the repos I have enabled all seem harmless,
though there are several of them:
[adobe-linux-x86_64, CentOS-CR (cr), epel, kbs-CentOS-Extras, rpmforge.

The system (which is in another country) seems to be running fine.
If I leave it will it sort itself out in time?

You need to use GPT partition table to manage above 2TB.
Traditional DOS partition can't manage above 2TB.
fdisk can't work with GPT, it's possible sfdisk don't work too.

Try using parted /dev/device, and
mklabel GPT

[CentOS] biggest disk partition on 5.8?

[Alan McKay]

Hey folks,

I have a Sun J4400 SAS1 disk array with 24 x 1T drives in it connected
to a Sunfire x2250 running 5.8 ( 64 bit )

I used 'arcconf' to create a big RAID60 out of (see below).

But then I mount it and it is way too small
This should be about 20TB :

[root@solexa1 StorMan]# df -h /dev/sdb1
FilesystemSize  Used Avail Use% Mounted on
/dev/sdb1 186G   60M  176G   1% /mnt/J4400-1


Here is how I created it :

./arcconf create 1 logicaldrive name J4400-1-RAID60 max 60 0 0 0 1 0 2
0 3 0 4 0 5 0 6 0 7 0 8 0 9 0 10 0 11 0 12 0 13 0 14 0 15 0 16 0 17 0

I'll just point to the EPEL section of the wiki.centos.org Repositories page,

True enough as a fact, but it sort-of sounds like a criticism for
something that's not really practical.  Normally packages would be
accepted into EPEL if they meet the guidelines and there is usually
some reason if they are elsewhere.

I dream of the existence of a repository I just activate and issue
   $ sudo yum install @tomcat

Like this one

Re: [CentOS] Repositories in CentOS 5.8

You've already gotten some excellent advice about this, but I'd like to add a 
few things, starting with a list of just a few factoids I've observed about 
repos and repo mixing:

1.) EPEL doesn't make it a priority (or even a goal) to work well with any 
other third-party repository;

2.) The mixability of other repos varies, with both repoforge/RPMforge and 
ELrepo taking pains to not overwrite base repo packages unless you enable their 
'extras' sub-repos (others may as well, I'm speaking from my own experience, 
and the repos I use the most are EPEL, repoforge, and ELrepo, and so I'm not 
even going to comment about the mixability of others, like remi, IUS, ATrpms, 
or others since I have either insufficient or old information about them);

3.) At least one useful repository that I use on certain production machines, 
the CERT Forensics repo, relies on both EPEL and RPMforge/repoforge, so look 
carefully at the mixing issues of each of your selected repos' upstream repo 
dependencies;

4.) Random mixing of packages (like random downloads from pkgs.org) is certain 
to cause problems;

5.) The fewer the number of repos you use the more stable your package set will 
be.  That is especially true if you mix 'specialty' repos like OpenNMS and 
PacketFence (or even slightly off the wall ones like LinuxTech (which has a 
usable handbrake for CentOS 6, for instance)), or upstream repos like the one 
from the PostgreSQL RPM building project to get the latest PostgreSQL on you 
system;

6.) There is no such thing in repositories as 'one size fits all.'  What will 
fit your needs depends a great deal on what 'production' is defined to be in 
your specific instance.  

(For a server in 'production' that is serving typical network service loads 
(file, print, web, e-mail, databases, etc) you're going to need some specific 
things (where 'things' is defined as the set of packages and interdependencies 
between packages).  A 'production' research/development desktop (we have a few 
here) will need different things; a 'production' embedded machine controller 
(we have a couple of those, too) will need yet another different set of 
things.);

7.) You really need to look at the packages that you need for your application 
and then individually investigate which repo or repos has the packages that you 
need, built the way you need them.  And look at the longevity of the repo; both 
RPMforge/repoforge and EPEL, for instance, have been around a while and are 
pretty well maintained;

8.) The recommendations on the CentOS Wiki repositories page are very good 
starting points, but what you specifically need in production is something 
you'll need to determine for yourself after doing some testing with different 
repos.  And I'd keep some testing machines or VM's available to test various 
repos over time to see how they work or don't work with each other, and you 
might even want to build your own repository, depending upon your specific 
critieria;

9.) Don't mix from-source (./configure;make;make install) installed packages 
and packages from repositories unless:
a.) You know exactly what you're doing;
b.) The from-source package builds all its own dependencies (like Plone 
does);
c.) The from-source package's author won't support it otherwise.

10.) Learn to use yum and its tools effectively to keep mixing issues at bay 
(priorities, plugins, and the command line parameters to enable and disable 
individual repositories as needed are the ones to start with);

Now, a non-factoid observation: if you think about it, it's quite an amazing 
thing that so many people are so willing to keep repositories of packages up to 
date at no cost to the end-user, given the very definite benefit and value of 
those updates (which is why I can't really complain if a repo is a little out 
of date, or if two repos that aren't costing me any opex won't mix just the way 
I want them to) and the very real cost to the maintainer, in terms of time, 
stress, frustration, and money.  

Having kept packages up to date for public consumption before, I understand all 
too well the trials of a packager and the entitlement syndrome some users seem 
to have.  

And thus my last recommendation: 

11.) be prepared to do some work on your own to make different repositories 
work together for you, and be patient with the maintainers of those 
repositories when they don't work together the way you might like.  They don't 
have to listen to you, but most will listen if you approach them the right way, 
respectfully acknowledging their valuable contribution to your bottom line.

YMMV, FWIW, IMHO, HTH, etc.

Re: [CentOS] Tomcat7

[Rudinei Dias]

Hi.
This I had found. The first thing to do is google search.
I've had bad experiences mess configuration caused by not using RPM on
Centos installers.
Even so, thanks.

The question is if anyone knows where you have a RPM repository for the
tomcat7 HREL6/EL6.

A slight clarification: what happens on a failover cluster is that you've
got heartbeat running, and each machine looks to see if the other's still
alive. At this point, one is live, and the other's standby. If/when the
standby notices it cannot see - even a ping - the other address, or it can
be configured to look for a service, such as doing a default search (for
apache, that might be a wget ImAlive.html) - it tells the system to assert
the IP, and turns up all services for which it's been configured.

I haven't done it, but I'd say you could easily configure heartbeat to
check, and if the IP's visible, but the service times out, to tell the
live one to turn down services, and to take over primaryhood.

Hope that's clearer.

Agreed - and the most likely source of conflicts is when you have
installed packages from  2 different 3rd party repositories or
unrelated sources.  Normally any single source will test against a
stock RHEL base, but not other 3rd party packages, and when package
dependencies change in future updates you have the potential for
conflicts.   Not even copying packages to your own repository can
ensure that packages from multiple different sources will be able to
track future updates without conflicts.

But, EPEL is fairly safe by itself and has a huge number of packages
that are maintained pretty well.

[CentOS] openldap mmr + heartbeat hot standby

[Wessel van der Aart]

Hi List,

I've setup 2 openldap servers in n-way multimaster replication mode in a 
test environment, both run centos 6.2,
this works well but now i'm trying to  make these 2 servers failover 
using heartbeat.
i've got no experience with heartbeat (or setting up clusters in 
general) however from what i understand heartbeat starts/stops the 
service if the server has the virtual IP assigned or not.
this would be fine for httpd , but since replication doesn't work when 
slapd is stopped i was wondering if anyone knows if there is a way to 
setup heartbeat with a hot standby? so that the service keeps running 
but the ip does gets reassigned when one goes down.

Thanks, Wessel

Re: [CentOS] 200 Stream not found errors in flash player and firefox

[ken]

Rob, what are you doing to get the error message?  I.e., what command or 
application are you invoking and where does the "200 Stream" error 
appear?

I've been having problems with flashplayer also-- for a long time and 
over many upgrades.  When, using firefox, I visit a site which invokes 
flashplayer, the cpu load begins to increase it can go from 0.4 to 
6.8.  If I then close the tab to that site, the cpu load goes back down 
to where it was.  I've talked with friends who use Mac OS X and Windows 
and they both experience similar problems with flashplayer, so I always 
assumed it was something in flash.

[CentOS] Reset adapter

[sebastian]

Hi,

one of our rented root-server has a problem with the network-adapter.The 
network is interrupted from time to time and i can not longer connect to 
our server. We can only reboote (remote) the server and restart the network.
I think it was an network-driver-problem from an "Intel Corporation 
82574L Gigabit Network" --- e1000e
But now i have install a new kernel-driver and i have the same problem 
again.

That'll work also but for that one user account

Also yes packagekitd is a binary but controled by DBUS.  I think that is
just silly because it has no service command to stop it.  Stopping
'dbus' should take care of it but then you will prolly be stopping
really needed things.

There are repositories that might not have such policies.
There are rpm downloads that are not yum-ified.
