I have been using tigervnc-server with CentOS6.2 since last summer. I worked well. Two days ago, I installed CentOS6.2 with Software development environment in a new PC and after "yum -y install update", tried to insall tigervnc-server using "yum -y install tgervnc-server" Installation itself has finished without any touble but vncserver didnot start with the message like belows [centos@matlablnx66 ~]$ vncserver -geometry 1600x956 :1 xauth: (stdin):1: bad display name "matlablnx66:1" in "add" command WARNING: The first attempt to start Xvnc failed, possibly because the font catalog is not properly configured. Attempting to determine an appropriate font path for this system and restart Xvnc using that font path ... Could not start Xvnc. /usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids /usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids [centos@matlablnx66 ~]$

atheros wifi on my oqo2
by Robert Moskowitz 14 Mar '13

14 Mar '13

I have a few oqo2 units that I use for testing, normally using the dongle for ethernet connection. Well supposedly they have atheros wifi. in dmseg I see: ath5k 0000:03:04.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 ath5k 0000:03:04.0: registered as 'phy0' ath5k phy0: Couldn't identify radio revision. ath5k 0000:03:04.0: PCI INT A disabled I press magic <fnc-?> per http://www.expansys.com/ft.aspx?k=119902 but NetworkManager is not adding wifi as a networking device. There is no file under /etc/sysconfig/network-scripts/ifc-* either. How can I get the wifi working?

[OT/HW] hardware raid -- comment/experience with 3Ware
by Arun Khan 13 Mar '13

13 Mar '13

Greetings, I am looking for a hardware raid card that supports up to 4 SATA II hard disks with hot swap (compatible raid cage) I have short listed two LSI/3Ware cards: 1. 9750-4i 2. 9650SE-4LPML Both appear to be well supported in Linux. I would appreciate your personal experience with the CLI tools provided by LSI. Can they be configured to send email for disk failures or SMART errors? Is there a Web interface for monitoring? Any preference between 1 and 2 above. Thanks for your time and suggestions. -- Arun Khan

UEFI Bootable ISO HowTo
by Skeeve Stevens 13 Mar '13

13 Mar '13

Hey all, We've developed our own microserver platform sitting on top of CentOS 5.4. We deploy them in many locations and normally use netbooks for this purpose. This has worked fine for years, except most netbooks have started to disappear (in Australia). The lowest price hardware I found the other day was the ASUS F201E (X201E in USA). It is the right size at the right price... but it runs on UEFI Bios. This has caused me to burn hours trying to figure what is going on until someone pointed me to: CentOS-6.3-x86_64-minimal-EFI.iso - which worked fine (except no LAN drivers for this device are present - damnit). As we roll our own ISO... I want to re-build our platform on top of CentOS 6.4 - or something current, but while the OS isn't an issue... the EFI aspect is... and I can't seem to find out how to roll and ISO with EFI support. Does anyone know of a doc out there which might be able to assist me with getting something going? ...Skeeve *Skeeve Stevens - *eintellego Networks Pty Ltd skeeve(a)eintellegonetworks.com ; www.eintellegonetworks.com Phone: 1300 239 038; Cell +61 (0)414 753 383 ; skype://skeeve facebook.com/eintellegonetworks ; <http://twitter.com/networkceoau> linkedin.com/in/skeeve twitter.com/networkceoau ; blog: www.network-ceo.net The Experts Who The Experts Call Juniper - Cisco - Cloud

replacing joe
by Michael Schumacher 13 Mar '13

13 Mar '13

Morning everybody, I am still using good old joe editor on my CentOS machines although it is no longer included in the CentOS repositories. Is there any comparable "wordstar" compatible editor that is part of the standard distribution? And no, I don't want to use Emacs. :-) best regards --- Michael Schumacher

Where's crm (from pacemaker-cli) on CentOS 6.4?
by Antonio da Silva Martins Junior 13 Mar '13

13 Mar '13

Hi, After upgrade the nodes on one of my HA clusters I find that "crm" isn't on the pacemaker-cli package. After some research on the web I find this: http://www.gossamer-threads.com/lists/linuxha/pacemaker/84376?page=last That thread points to this OpenSuSE repo: http://download.opensuse.org/repositories/network:/ha-clustering/RedHat_RHE… Which suply the new "crm" from "CRM shell" project: http://savannah.nongnu.org/projects/crmsh/ Then, after upgrade, put the new repo on, and install "crmsh". Hope this helps. Att., Antonio. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Antonio S.

looking for bind 9.9 for Centos 6 - found 'CentAlt'
by Robert Moskowitz 13 Mar '13

13 Mar '13

Yesterday, in a hall conversation, I was strongly directed to bind 9.9. It can do the inline signing of a zone changes that 9.8 can't. So today, I went digging for someone supplying it all nicely packaged for me; my servers are all i386. I found a couple sources but the one that I found is: http://pkgs.org/centos-6-rhel-6/centalt-i386/ but digging deeper I found it pointing to: http://centos.alt.ru/repository/centos/6/i386/ So I am not so sure I want to get it from there. What are my choices? I found another site, but it only has x86_64 rpms.

Weird mouse behaviour (after upgrade to CentOS 6.4?)
by Toralf Lund 13 Mar '13

13 Mar '13

Hi. For a few days now I've had some pretty annoying mouse-related problems on my CentOS setup. I'm not sure if I get "false" mouse events or what it is, but quite frequently I find that the system has somehow got into a state where mouse clicks are not properly received - although I can move the pointer all right, and they keyboard also works just fine. The only way I've been able to get back to a sane state, is to switch to a different virtual console via Ctrl+Alt+F-key, then back in a similar manner. This seemed to start after the last round of automatic updates, which took me to CentOS 6.4, although I suppose this might be coincidence. Has anyone else seen this kind of behaviour? Any idea at all what's going on? - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.
