En el servidor de nuestro laboratorio hemos migrado el sistame de virtualización de VMWare Server 2 a KVM. Hemos realizado una instalación limpia del sistema operativo, hemos instalado los módulos del KVM y todo aparentemente sin ningún problema. Hemos creado dos máquinas virtuales, una con Windows XP Professional y otra con Ubuntu Desktop 9.04 x64 y aparentemente todo parece correcto y sin ningún error en ninguno de los procesos. Tanto en el servidor CentOS como en la máquina virtual Ubuntu hemos instalado FreeNX para el acceso gráfico desde otros ordenadores de la red interna. Y aparentemente todo correcto. El problema aparece cuando estamos trabajando sobre la máquina virtual Ubuntu, cuando le parece el servidor se queda frito y no responde ni desde el teclado local, ni a través de la red con ssh, www, ftp, etc... ni siquiera responde a un ping. Según aparece en la web de KVM (http://www.linux-kvm.org) este sistema se encuentra implementado desde el kernel 2.6.20 y en los repositorios de CentOS solamente está la versión que tenemos instalada que es la 2.6.18-128.1.16.el5, no sabemos si puede ser ese el problema. ¿Alguien tiene alguna idea, recomendación, consejo, sugerencia, etc, de cual es el problema?

Re: [CentOS] Formatting print with awk and ORS
From: Joseph L. Casale jcas...@activenetwerx.com
I have a command I execute:
awk 'BEGIN { ORS= } { print \ $1 \ }' input_file
which gives me exactly what I need, all field one's in quotes on one line
each separated by one space. I now need to print a single quote around all
of this, but the ORS flag is screwing me up, it's causing every attempt I
try to repeat for every record.
awk -v q=' ' BEGIN { ORS= ; printf(%s, q) } { print \ $1 \ } END {
printf(%s, q) } '
or

[CentOS] Init checking for processes that are configured to respawn
Hi folks, I have a sophisticated question for which I can't find any hints on the web: If you configure init (via /etc/inittab) to respawn processes (like the getty processes) when they exit - how often does init check for the existence of such a process? Does it check actively at all or does it rely on some kind of inter process communication? I am not a programmer, so maybe the second question is completely nonsense. Any hint or help is appreciated. Dirk ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Memory reporting...
try vmstat, see all the options in man vmstat it reads from
/proc/meminfo and /proc/stat
#vmstat -a 5 -S m
on my system with 2 GB ram it shows that i'm having 18 mb free, 922 mb
inactive and 821 mb active
my running processes only use a tiny bit of my active ram, you can check
it with:
#ps aux | awk '{print $4\t$11}' | sort | uniq -c | awk '{print $2
$1 $3}' | sort -nr
This is normal behavior, for better understanding please read this
excellent article from redhat:

[CentOS] Permission problem
Hi, I have to solve an apparently simple permission problem, and I don't know if it's the sunny weather or birdsong, well... I just can't figure it out. Here goes. I have a bunch of users in a public library. Some are administrators: they handle the library, write the docs for everyone, etc. Then you have the agents, who take care of lending books and fetch them when they get returned. And then you have the odd anonymous user, using the PC with a guest account. Let's make thing simple and start out with one machine. Every single user has a /home/user directory. Plus, I added the following directories: /home/pub and /home/echange Then, I created two groups, administrators and agents. Here's what I'd like to achieve (but I think my IQ is just below the required limit :oD): 1) Members of the administrators group have unlimited read/write access to /home/pub and below. 2) Members of the agents group have read-only access to /home/pub and below. 3) All the others (that is, members of neither administrators and agents) have no access at all to /home/pub, not even for listing the directory content. The thing is: I can't seem to formulate my problem in terms of user/group/others, as there are no owners, but two distinct groups involved. Any idea how to crack that nut?

Re: [CentOS] Permission problem
Yes, as Barry said, use ACL for giving permission for group agents. The permission must be 770 and the group associated to /home/pub must be administrator. Then give acl rx (setfacl -m g:agent:rx /home/pub) to /home/pub. This should solve the issue. Make sure your filesystem is mounted with ACL support.

First of all, thanks for the instant replies. I took a peek at ACLs and
how they work. But then, being a fervent adept of the KISS (Keep It

ago), I decided to shunt the KICK (Keep It Complicated Kiki) principle :o)
More often than not, we do things in a quite complicated manner...
before ending up finding a simple solution to the problem.
Anyway, here's the solution to my problem, without ACLs, just good old
plain chown and chgrp. I took some notes, they're in french, but the
Linux bits are universal :o)

La médiathèque de Montpezat compte cinq agents de prêt :
* Jean-Claude Pascot (jcpascot)
* Nicolas Kovacs (nkovacs)
* Chantal Geins (cgeins)
* Maryse Pascot (mpascot)
* Renée Marseille (rmarseille)
Les visiteurs de la médiathèque peuvent utiliser l'ordinateur avec un
compte spécifique :
* Utilisateur invité (invite)
Jean-Claude Pascot et Nicolas Kovacs doivent pouvoir créer des documents
et les mettre à disposition dans un répertoire partagé en lecture seule.
(Remarque: peut-être que chacun aura 'son' répertoire...)
Tous les agents doivent pouvoir échanger des documents dans un
répertoire partagé accessible en lecture et en écriture.
Les visiteurs ne doivent pas avoir accès aux documents des
bibliothécaires, même pas en lecture.
Chacun des utilisateurs sera membre du groupe de connexion initial
'agents', qu'il va donc falloir créer au préalable.
# groupadd agents
Pour voir les caractéristiques de ce nouveau groupe :
# grep agents /etc/group
agents:x:503:
Éventuellement, c'est une bonne idée d'assigner un GID spécifique à ce
groupe :
# groupmod -g 1000 agents
Pour effacer un groupe, utiliser 'groupdel' :
# groupdel agents
Ensuite on crée les utilisateurs :
# useradd -c Nicolas Kovacs -g agents -u 500 -m nkovacs
# useradd -c Jean-Claude Pascot -g agents -u 510 -m jcpascot
# useradd -c Chantal Geins -g agents -u 520 -m cgeins

# useradd -c Renée Marseille -g agents -u 540 -m rmarseille
# useradd -c Utilisateur invité -u 1000 -m invite
On active les comptes :
# passwd nkovacs
# passwd jcpascot
# passwd cgeins
# passwd mpascot
# passwd rmarseille
# passwd invite
Nicolas Kovacs et Jean-Claude Pascot veulent pouvoir mettre à
disposition des documents à tous les agents, en lecture seule.

Maintenant, Jean-Claude Pascot peut créer des documents dans son
répertoire public /home/pub/jcpascot :
# su - jcpascot
$ cd /home/pub/jcpascot/
$ echo Info importante info.txt
$ exit
Nicolas Kovacs peut faire de même dans /home/pub/nkovacs :
# su - nkovacs
$ cd /home/pub/nkovacs/
$ echo Autre info importante infobis.txt
$ exit
Un agent peut maintenant accéder aux infos en lecture seule :
# su - cgeins
$ cat /home/pub/jcpascot/info.txt
Info importante
$ cat /home/pub/nkovacs/infobis.txt
Autre info importante
En revanche, il ou elle ne pourra pas modifier le contenu de ces deux
répertoires. Ce droit est réservé aux seuls propriétaires respectifs.
Il ne reste plus qu'à créer un répertoire d'échange où tous les agents
disposent d'un droit de lecture et d'écriture indiscriminé.
# mkdir -v /home/echange
mkdir: création du répertoire `/home/echange'
# chgrp agents /home/echange/
# chmod 3770 /home/echange/
# ls -ld /home/echange/
drwxrws--T 2 root agents 4096 jui 7 16:56 /home/echange/
Explication : Ici, on a défini en même temps le droit SGID pour le
répertoire, ainsi que le 'sticky bit'. Si l'on crée un fichier dans un
répertoire qui possède le droit SGID, son groupe sera identique à celui
du répertoire. La conséquence, c'est que l'ensemble des fichiers du
répertoire appartiendra au même groupe, ce qui est intéressant pour un
répertoire accessible à plusieurs personnes.
# su - jcpascot
$ cd /home/echange/
$ echo Info importante info.txt
$ ls -l

Small mistake. This last line should go chmod 2750, so every file

Could you please give me advice about issue described below. My friends have to use a PC with old hardware for a few months. They've got 128MB of RAM, 20 GB hard drive; Pentium 3 processor. At the moment they have windows xp running on it, but it's very slow. What are the system requirements for CentOS 2 or any other version of this OS that may be suitable? Can you recommend any other Linux distro that would be easy to install and to use? Yes. CentOS 5. Start with a minimal install (base system). Install and configure X. Only install packages you really need, be sure to deactivate all unnecessary services. Go for XFCE, IceWM, Fluxbox or some other lighter window manager. This sort of configuration is running in my neighbour's home, I installed it for them on their old PIII-500 with 128 MB RAM. To add - I run CentOS 5 just fine on an IBM Thinkpad T20 (700MHz PIII when plugged in, 550MHz on battery) with 384MB of ram. I ran it just fine on 256MB until one of the ram modules died. I then ran it on 128MB painfully while waiting for the replacement (256MB) chip to arrive. Note though that I'm running the full gnome GUI. Disable JavaScript except when you absolutely must have it, browsing with JS / flash enabled crashes low memory machines. Don't use OpenOffice - AbiWord an Gnumeric both do well on low memory machines. For that matter, so does LaTeX as it just uses a text editor until you are ready to compile your document, but LaTeX has quite a learning curve. If the 20GB HD is a 5400RPM (probably is) try to get a 7200RPM drive - that's what I did in my old laptop and the difference was night and day. If it is a desktop, and you do replace the drive with faster spinning, if there's room to continue using the older drive - you can use the older drive as dedicated swap, which will help a lot. You don't need 20GB of swap, you can partition it, but don't use the non swap for anything much other than storage of stuff you don't need to access often. This, btw, is what I love about Linux.

I believe once a file system is unmounted all of the writes have been flushed to it. You can see the change in behavior: - write a bunch of data to a disk, run sync, then unmount, it should unmount immediately - write a bunch of data to a disk, then unmount, it may take a few seconds(or more) to unmount. Not sure why those popups aren't showing up on a consistent basis, I don't use CentOS as a desktop, my Debian desktops don't show any messages I don't think, though Ubuntu seems to. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Is there an openssh security problem?
is there a security issue on CentOS 5.3 with openssh 4.3? If this is a real zero-day exploit.. then yes, there is an issue.

Well, there are usually behind-the-scenes communications between various vendors to get security-relevant bugs fixed in a coordinated fashion.

When I added the EPEL Repository, the number of excluded packages went from approximately 400 to 1705. My belief is that if EPEL had a high priority, it would replace a *LOT* of packages I do not want replaced. Generally, you're right - but in this case, it seems to be purely an rpmforge problem. I'm getting similar problems with a mail gateway which has a lot of Perl modules to support amavisd/clamav/spamassassin: There was a problem updating the system. The following error message was reported: Failed to build transaction: Missing Dependency: perl(Compress::Raw::Zlib) = 2.020 is needed by package perl-IO-Compress-2.020-1.el5.rf.noarch (rpmforge) Checking svn at rpmforge shows: Name: perl-Compress-Raw-Zlib Version: 2.020 Release: 1 so it's in the repo. I assumed it was a problem with the mirror I was using (ftp-stud.fht-esslingen.de) so I excluded in it fastestmirror.conf and tried again, this time using fr2.rpmfind.net, but no joy: Error: Missing Dependency: perl(Compress::Raw::Zlib) = 2.020 is needed by package perl-IO-Compress-2.020-1.el5.rf.noarch (rpmforge) At this point, I'm not going to worry too much about it - it's in the system and should eventually turn up.

[CentOS] md0 mounted rw on boot
Hi folks, I updates one of my long-running CentOS 4.x systems today, and afterwards it wouldn't boot properly. My issue was that it would start, then announce: Checking root filesystem /dev/md0 is mounted. e2fsck cannot continue. After much twiddling around, I discovered that if I booted from the first kernel I had, it would boot properly. Now this is a hand-rolled RAID, not an anaconda-generated one. And I seem to recall generating an initrd myself in order for the boot process to work. Does this mean that I have to generate a new initrd every time I want to boot to a new kernel? For the record, this kernel failed: title CentOS (2.6.9-78.0.22.EL) root (hd0,0) kernel /boot/vmlinuz-2.6.9-78.0.22.EL ro quiet root=/dev/md0 initrd /boot/initrd-2.6.9-78.0.22.EL.img ...while this one succeeded: title CentOS-4 i386 (2.6.9-34.EL) root (hd0,0) kernel /boot/vmlinuz-2.6.9-34.EL ro root=/dev/md0 initrd /boot/initrd-2.6.9-34.EL.img And there are several other kernels on the system, but I honestly don't know which ones have been run successfully.
