[CentOS-virt] build custom domU kernel from centos kernel source
Hi, i am trying to build a custom xen kernel from CentOS source kernel rpm . What i want to achieve is to have custom domU kernel without modules, which will boot domU machine without having /lib/modules . My first try is to simple disable Loadable module support , so i have followed tutorial on CentOS wiki for kernel building http://wiki.centos.org/HowTos/Custom_Kernel . Now it is building, my question is will it work? - again all i have done is to disabled loadable module support. Can someone please point me to sucessfull end? Thanks in advance!

Hola amigos de la lista
Quiero en pasos escalonados migrar todos mis servicios de window$ para
linux. He instalado bind en un centos 5.1 y declarado una zona esclava a
la cual se transfiere desde un dns en window$ 2003. He revisado la zona
en /var.../slaves/dominio.db y tiene todos los records del dominio
master; ademas he revisado los logs y arranca bien. En named.conf tengo
un acl para mi segmento de red así como abierto el puerto 53 en
iptables. Pero si hago consultas con nslookup (desde window$) no
obtengo respuesta y no veo ningun message de error.
Mis preguntas son dos:
1. ¿ alguna consideración adicional para consultas desde window$ ?
Pues no debería haber ninguna especial
2.- ¿ algun otro sitio adonde vayan los logs de named o forma de
configurarlo?
Que tal si miras un tcpdump el tráfico que recibe/responde tu GNU/Linux.
Seguro eso te dará mas luces de donde está el problema.
Lo otro es habilitar el query log de Bind. Algo así, en named.conf:
--
logging {
channel query_logging {
file /var/log/named_querylog
versions 3 size 100M;
print-time yes; // timestamp log entries
};
category queries {
query_logging;
};
};
--
Porfavor revisar la documentación de Bind.
Gracias
Exitos !

Re: [CentOS] Somewhat OT:
Sorry for the top post. Nagios can start very simple, but has the ability to end up very complex. It's configs take a modular approach, you have monitors, monitors belong in groups, groups have operators/administrators, etc. My big problem with nagios is when I used it last it didn't keep monitor history which makes trending impossible. I eventually went with ipmonitor from solarwinds which has a nice web interface, all the reporting you may want and works pretty much like nagios does, but through a web interface. Very reasonable pricing too. Of course I believe it only runs on windows, but it runs very nicely as a VM guest. -Ross - Original Message - From: [EMAIL PROTECTED] [EMAIL PROTECTED] To: CentOS mailing list centos@centos.org Sent: Tue May 13 07:34:50 2008 Subject: Re: [CentOS] Somewhat OT: 2008/5/13 Kai Schaetzl [EMAIL PROTECTED]: Sergio Belkin wrote on Mon, 12 May 2008 23:07:20 -0300: [CentOS] Somewhat OT: even then please write a senseful subject next time!

Thanks Les, OpenNMS sounds interesting, in order to monitor a network switch, should I write XML files by hand? There are a few things you still have to edit by hand, but development is very active and most of the configuration has been moved into the web interface. If your switches are common brands, the MIBs will already be included, and if you set the snmp collector to store values for 'all' interfaces it will build graphs for them automatically - or you can let it detect nodes, then follow the admin link for the node and pick the interfaces to collect. If you don't like the default graphs or want to add more, you might need to modify the xml files that describe them. but to start out, just set the snmp defaults and a discovery range and see what it does. -- Les Mikesell [EMAIL PROTECTED] ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

We've evaluated some of the other options already mentioned here: zabbix, opennms, zenoss, even mon, and big-brother and friends, and have always decided that nagios is the best product for our needs, as far as system monitoring goes. The initial learning curve is about medium compared to some, and once you've gotten over that hump, there just don't seem to be others. I've recommended Nagios to a few less-than-seasoned sysadmins who were able to take the templating concept and run with it. We have also setup cacti for the snmp statistics keeping. Nagios does have performance data capabilities now, they feel sort of tacked on to me. The folks over at http://www.centreon.com/ are working on an integrated user interface that includes statistics keeping using Nagios as the monitoring engine which looks as though there may be some promise, if I was starting over I'd definitely evaluate that. I hope this is of some help in your review process.

[CentOS] build custom domU kernel from centos kernel source
Hi, i am trying to build a custom xen kernel from CentOS source kernel rpm . What i want to achieve is to have custom domU kernel without modules, which will boot domU machine without having /lib/modules . My first try is to simple disable Loadable module support , so i have followed tutorial on CentOS wiki for kernel building http://wiki.centos.org/HowTos/Custom_Kernel . Now it is building, my question is will it work? - again all i have done is to disabled loadable module support. Can someone please point me to sucessfull end? Thanks in advance!

Once you have confirmed that you can make the change to fstab (/etc/fstab). Be really careful when you do that as the wrong changes can make your system unbootable.

Re: [CentOS] GFS + quotas
No problem Scott, thanks for the reply, you're the only one that even tried :). Our userbase here has become accustomed to being able to check their quota from any machine they are on, and apparently not being able to do so it just horrible horrible from my boss's standpoint. If there is no way to do this, I'm faced with having to dump the entire filesystems quota every hour or so and write a custom quota command that reads this flat file to return their results, which is ugly ugly if you ask me, but he insists we MUST be able to provide them this info. The file server we are migrating from was a clustered Tru64, and when it starts/exports nfs, it provides nfs with the quota information from the underlying OFS filesystem.

[EMAIL PROTECTED] ~]# pvdisplay --- Physical volume --- PV Name /dev/hda9 VG Name VolGroup00 Ok, that clarifies that the VG on /dev/hda3 is not in use at all and your CentOS is indeed installed on the LV on hda9. I still wonder how this mess was created. Did you have an earlier Linux installation on it and forgot to wipe that completely before you installed CentOS? Kai: There was an earlier installation with Fedora Core or CentOS, and Windows 98 on it.. I think that I wiped the drive, before installing Win XP and CentOS 5, but that was almost 6 months ago and I am not 100% positive that I did in fact wipe the HD. For the earlier Linux installations, I did the partitioning manually, with Disk Druid. I think the easiest way to get you back on track is to edit your fstab. There is a line about /boot in it that points to /dev/hda3. Change that to /dev/hda8. This is all. But before you do that, please check that there is indeed a grub.conf on it that contains the old information. You know the path I gave you was slightly wrong. Once you have confirmed that you can make the change to fstab (/etc/fstab). Be really careful when you do that as the wrong changes can make your system unbootable. I will reread this entire thread and then keep my fingers crossed and do it. If I make her system unbootable, my wife will be unhappy.. Once the change is done the *next* kernel that gets installed will go to the correct boot partition and the correct grub.conf will be updated with the correct information to boot with the new kernel.

On my old (even deader) Hammer (Panasonic) burner, it was 8x (didn't support 12x). Now I have a Pioneer 18x that supports 12x as the next lowest speed (!), and a brang new Samsung (TSST) 20x drive that maxes out at a whopping 2.47x (no kidding - that's my need for the new firmware...).

[CentOS] Centos Freezing
Hello, For some reason at different times Centos will freeze and not allow me to do anything. This doesn't happen while I'm working on the system but after I have locked my session and then return. It could goes days without a lockup and then the next time I try to log in it'll be frozen. I would like to know if anyone else has seen this or knows of a fix or where I could start to look to find out if there is a process or something causing this. I normally have the same programs running so I don't think it could be caused by me starting and then leaving something new running.

For example: iptables -A INPUT -j CUSTOMCHAIN iptables -A CUSTOMCHAIN rule1 iptables -A CUSTOMCHAIN rule2 Should we add: iptables -A CUSTOMCHAIN -j INPUT ? Or, it will automatically go back to CHAIN when there's no more rule?
