domain name display issue in linux pc
by padmaja.rv＠vodcalabs.com 14 Feb '08

14 Feb '08

Hi, Thanks for your response on the kernel switching.I was away and could not reply immediately. Right now, I am facing a differentissue. I have to set up DNS server using BIND on Centos 4.3. When Itype the hostname on Centos, it shows: sipserver.vodcalocal.com But the cli prompt has root@sipserver~ meaning only the sipserver part of the hostname is displayed. whyis this so? What is the actual hostname then? I see in the /etc/sysconfig/network that thehostname is sipserver.vodcalocal.com the /etc/hosts file has the followingcontent: # Do not remove the following line, orvarious programs # that require network functionalitywill fail. 127.0.0.1 localhost.localdomain localhost sipserver 192.168.50.51 sipserver.vodcalocal.com The /etc/sysconfig/network has thefollowing config: NETWORKING=yes HOSTNAME=sipserver.vodcalocal.com I have seen in many forums that the/etc/sysconfig/network file has many other entries like domain name,gateway type, gateway ip etc, which are not present in myconfiguration. when i type $ domainname, i get-- (none) $ domainname -d vodcalocal.com $ domainname -f sipserver.vodcalocal.com Why does not the command domainnamelist the domain name? also domainname -f and domainname -d displaydifferent results. can the machine have the domainname and hostnamesame if I am going to run dns server on it? I run a SIP server on this PC whichneeds the domainname set but whenever I type echo $DOMAIN_NAME, itshows blank and I have to export the path variable DOMAIN NAME andset it. On another screen, I again dont see the domain name set. Howto set the domain name across all terminals and sessions andrestarts?an Thanks Padmaja

Ah. You're not running the PAE kernel. Reboot the box, and bring up the grub menu. Choose the PAE kernel. Then you'll see what you're supposed to and can uninstall the other kernel(s) From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Van Staden, Allan Sent: Thursday, February 14, 2008 3:33 PM To: CentOS mailing list Subject: RE: [CentOS] FW: Memory Problem Uname -r = 2.6.18-53.1.13.el5 I installed webmin and from there I see that the total memory is 2.96 GB and when I run top it shows Mem: 3107572k total.

Backing up remote system
by Scott Ehrlich 14 Feb '08

14 Feb '08

I have an Overland Arcvault tape library, a CentOS 5 box, a Windows XP system, and RAID box that supports NFS and CIFS. The RAID box is remotely located and acts as central file storage. I might normally use dump to perform backups, but as was learned here, and on dump's man page, dump doesn't support remote file systems such as NFS or CIFS. So, for now, I've connected the library to a Windows XP system, running Service Pack 2. I have a shell script that tar gz's the directories of choice to preserve, places them in /backup, and, via samba's config of making /backup available, have it mounted as a drive letter on the XP system. I'm then using XP's built-in backup/restore program to store the contents of /backup to tape, and that is working fine for now. Is there a reliable Linux/CentOS-based way to do this, too? I know people keep saying use Amanda and/or bacula and be done with it, but in the event something goes wrong and the mysql, etc database gets corrupt, and people want their data back, it would be much easier to use a readily-available command, like cpio, tar, etc, to do the job. I've also elected to tar gz the contents ahead of time, for if I were to try and directly archive some of the files via a CIFS mount, I've experienced permission problems with various files and folders. A local tar of the files has gotten around that, then just have the Windows box copy the tar files to tape. Now to see what options tar has for producing incremental backups with a cron'ed tar job, unless someone has a better, comparable approach with existing OS tools (tar, cpio, dump, etc). I want to retain as many permissions as possible. I've tried rsync before, but that also requires enough disk space for the file copying, and some of the options I've used have complains of proper permissions being kept during the process. Thanks again. Scott

Question on failing hard drives
by Jimmy Bradley 14 Feb '08

14 Feb '08

In my Cent OS machine, I have 3 hard drives, an 80, and two 200gig hard drives. One of the drives is obviously starting to fail, but I'm not sure which one. Is there a command line command in Linux that will check the drive integrity on all the hard drives and tell me which one is going bad? Thanks Jim

In security terms, is there any difference between ending a session (logout of X) and locking a session? Anne

Booting without a keyboard
by Gregory P. Ennis 14 Feb '08

14 Feb '08

Everyone, Is there a way to have Centos boot when no keyboard is present. I have a firewall and another mail server that would fit into a closet a little better without a keyboard. I tried to remove the keyboard but the system hangs giving me notice that a keyboard was not found. Greg Ennis

Re: [CentOS] How can I stop the eject of the DVD after install?

The machines I am installing on do not have a motorized tray that can automatically pull the DVD back in when a mount command is issued. You have to push the disk in manually.

limit number of per-vhost or per-user cgi processes?
by J. Potter 14 Feb '08

14 Feb '08

Hi List, Is there a way to limit the number of cgi processes Apache's suExec will fork for a given vhost or given user? (either solution is fine) suExec doesn't honor the /etc/security/limits.conf nproc value. mod_throttle seems to be dead; and I can't figure out if selinux might be able to manage this (although would rather not flip selinux from permissive to enabled). What are others doing? Thanks! -Jeff
