mirrors down?
by m.roth＠5-cent.us 05 Aug '10

05 Aug '10

Just went to update a couple systems this morning, and first one machine took nearly 15 min to find the mirrors (and it should be getting it all from our own repo, actually), and then the next one showed about 8-10 mirrors down, including Harvard and VCU. Anyone know what's going on? mark

Introduction and request for help with virtualization
by Kevin Chang 04 Aug '10

04 Aug '10

Good morning everyone. This is my first post to this list. I am very new to Linux so please bear with me. Also, English is not my first language so please excuse me if I am unclear. I am trying to install CentOS Linux operating system in a virtualization setup. I have already built four host machines with CentOS 5.5 and KVM virtualization. I can install fine if I do a manual installation. I am now trying to automate the process. To this goal, I have create multiple LVMs inside my new volume group. The name of the volume group is vmstorage_vg. The problem occurs when I try to run the installation. I found a script via google: #!/bin/sh virt-install \ -n calcnode01 \ -r 1024 \ -f /dev/vmstorage_vg/calcnode01 \ --cdrom=/software/iso/CentOS-5.5_x86_64-boot.iso \ --accelerate \ --vnc \ -x "ks=ftp://192.168.0.101/pub/ks/calcnode01.ks ip=192.168.0.101 netmask=255.255.255.0 dns=192.168.0.20 gateway=192.168.0.1 text console=ttyS0" When I start this script from the SSH terminal it starts but I cannot see anything being installed. I entered the virsh console and see the calcnode01 entry if I do a list. If I try to connect using virsh I do not see anything. The kickstart was created from the anaconda file created from the manual installation. I enabled the options to create the filesystems. I think the installation is waiting on some input but I cannot see any console. I have tried with and without the "console=ttyS0" option. Thank you everyone for your time.

Kerberized NFS4 w/AD 2008 R2
by James A. Peltier 04 Aug '10

04 Aug '10

Is anyone currently using CentOS 5.5 with 2008 R2 AD authentication and a fully Kerberized NFSv4? If so would you mind sharing your configuration with me? I have been able to successfully get it working with Windows 2003 as discussed earlier on the list http://lists.centos.org/pipermail/centos/2010-July/096374.html With the exception that I had to use dynamic UIDs on the machine since we don't have Services for UNIX installed. Instead of going with a long drawn out certification of Windows 2003 R2 w/SFU, we plan to target our deployment in line with our Windows 2008 R2 campus deployment. I have followed everything that I did with Windows 2003 to get it working but NFSv4 w/Kerberos doesn't seem to work with 2008 R2 at all. No matter what I try I consistently get WARNING: Client not found in Kerberos database while getting initial ticket for principle NFS/hostname@DOMAIN using keytab or ERROR: No credentials found for connection to server any help would be appreciated. I've been banging my head against a wall for a while now and may have damaged to many brain cells to see what's going wrong. -- James A.

force b/w printing
by Janez Kosmrlj 04 Aug '10

04 Aug '10

Has anyone an idea, how to force users to print b/w on a color printer. We are in the process to deploy color printers to some of our offices where they use centos 5.5 as their OS. They need the printers to print some advertisement material. But for everything else, they don't need it. And because of the costs of the color printing we would like to force them to use B/W where not explicitly necessary. Is there a way to force a printer driver to be just B/W even if it is a color printer. So i could install a second color printer which would only be available to a special print user.

how to install Atheros AR5008 on CentOS 5.5 in console-only mode?
by Rudi Ahlers 03 Aug '10

03 Aug '10

Hi all, I hope someone can help me. I'm trying to setup a D-Link DWA-547 on CentOS 5.5 x64 in console only mode, i.e. there's no X installed. The Wiki article suggests using NetWork Manager, but since there's no X installed on this server, it's not possible. How do I go about installing this card? Here's the output of lspci -v: 01:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01) Subsystem: D-Link System Inc Unknown device 3a6b Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 5 Memory at e1000000 (32-bit, non-prefetchable) [size=64K] Capabilities: [40] #80 [0000] Capabilities: [80] #00 [0000] -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532
