Odd hang on a 5.6 system
by Ken Smith 27 Mar '12

27 Mar '12

Hi All, I've been trying to trace the cause of a hang on a 5.6 i386 system. After running for almost a year, it hung last week, when I plugged in a screen it was blank, machine was unresponsive to the keyboard, over the network ssh and other daemons didn't respond but the thing has two network cards and routing from one to the other was still working. So the kernel was up and I suspected a dying disk. But smartctl -a revealed nothing untoward. Didn't see anything significant in the log files at the time. Logging had stopped when the machine hung. The machine rebooted normally and has run for almost a week and hung again with the same symptoms. Again rebooted, nothing untoward in the logs and smartctl still OK. But shortly after I left site this was logged in /var/log/messages Mar 27 16:52:04 cjcsrv kernel: INFO: task hald-addon-stor:2179 blocked for more than 120 seconds. Mar 27 16:52:04 cjcsrv kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Faster and faster
by Piero 27 Mar '12

Hi Centos Team, I was here the hard days in which CentOS 6 appeared would never appear, and then was CentOS 5.6 (maybe 5.7...do not remember well) that struggled to see the light and I was very afraid CentOS would not survive... but as I was worried in the past actually I'm very impressed of the speed of latest releases: what has changed? Just out of curiosity... Thanks for your hard work and great product, Bye Piero -- Stupid is as stupid does. Forrest Gump

Using NFSv3 and NFSv4 at the same time with CentOS6
by C. L. Martinez 27 Mar '12

27 Mar '12

Hi all, I have two centos6.2 servers acting as a nfs servers (nfsv3 for now). Due to some security requeriments, I need to share some folders using nfsv4 (with kerberos auth), but I have a doubt. Is it possible to serve shared folters using nfsv3 and nfsv4 (with kerberos auth) at the same time in the same server with centos6?? Nfsv3 is used to serve storage for three ESXi servers (and these ones only supports nfsv3). How can I do it?? Thanks.

Postfix master-slave configuration howto
by Ljubomir Ljubojevic 27 Mar '12

27 Mar '12

Hi guys. I have mail loop problem. I have master server (CentOS 5.x) for domain in question (lets call it *domainX.com* ). I used virtualmin to set it up for that and several other domains. It is Bind SOA for the domain and Postfix server. I will call this server *soa.domainX.com* Now, I have added internal CentOS 6.x server to the company owner of the domain. I have given it hostname *server.domainX.com* and created *user1* on it. It has Postfix server on it, without public IP, and has *soa.domainX.com* as relay server. What I need to learn is how to set up so mail for *root(a)server.domainX.com* and *user1(a)domainX.com* stay on the *server.domainX.com* and master Postfix on *soa.domainX.com* stops refusing mail for other domains with: "554 5.4.0 Error: too many hops (in reply to end of DATA command)" I am already searching the net, but would appreciate link to howto or hint what to look for, since I mostly find irrelevant hits.

Script for enabling screen savers in GNOME and KDE on Centos 5.x
by ankush grover 27 Mar '12

27 Mar '12

Hi Friends, I am trying to configure screensavers settings on Gnome and KDE running Centos 5.x 32-bit environment. I need to prepare a script which will be push by Puppet and this script should be able to change settings like idle_delay, set customized password-protected screen saver, enabling lock etc.. I have tried below commands for Gnome and somehow the settings are not taking place. The users screensavers setting remains the same. Gnome Settings: gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type int --set /apps/gnome-screensaver/idle_delay 4 gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type boolean --set /apps/gnome-screensaver/lock_enabled true gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type boolean --set /apps/gnome-screensaver/idle_activation_enabled true gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --set --type list --list-type=string /apps/gnome-screensaver/themes [blank-only] On KDE I am not able to get what settings should be there for enabling idle_delay, activating the customized password protected screen saver etc.. KDE Settings $ qdbus org.freedesktop.ScreenSaver /ScreenSaver Do let me know whether any more information is required or not. Regards Ankush
