pam max locked memory issue after updating to 5.2 and rebooting
by Rob Lines 08 Aug '08

08 Aug '08

We were previously running 5.1 x86_64 and recently updated to 5.2 using yum. Under 5.1 we were having problems when running jobs using torque and the solution had been to add the following items to the files noted "* soft memlock unlimited" in /etc/security/limits.conf "session required pam_limits.so" in /etc/pam.d/{rsh,sshd} This changed the max locked memory setting in ulimit as follows: Before the change rsh nodeX ulimit -a still gives us max locked memory (kbytes, -l) 32 After the change rsh nodeX ulimit -a max locked memory (kbytes, -l) 16505400 The nodes have 16gb of memory. Now after the 5.2 updates those files are all the same and on most of the nodes we haven't yet rebooted them due to log running processes but a few nodes have been restarted and now that jobs are starting to be put on them we are back to max locked memory of 32k rather than 16gb. The error we are receiving on those jobs is : libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes. This will severely limit memory registrations. libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes. This will severely limit memory registrations.

CentOS 5.2 - Nautilus - file types are not associated with an action and icons are not displayed
by Vaclav Mocek 07 Aug '08

07 Aug '08

Hi all, I use CentOS 5.2 as a desktop and the Gnome Nautilus doesn't display icons related to the file types and all associated actions ("open with") are lost. It is so bad, that the desktop shortcuts are displayed as ordinary files "Filesystem.desktop" or "openoffice.org-1.9-calc.desktop", and when I click on them, the Nautilus wants to know what it should do with these files. The problem emerged after I installed the new kernel (2.6.18-92.1.10.el5) and uninstalled packages "joystick", "slrn" and "planner". All user accounts have the same problem, when I run the Nautilus as root (sudo nautilus), it works fine => probably some access restrictions. I run the Nautilus with strace, but the output is too messy to provide some sensible information. Any hint what to do is welcomed. Best Regards Vaclav

Kernel 92.1.10 build issue
by Mark Hull-Richter 07 Aug '08

07 Aug '08

I pulled down the 2.6.18-92.1.10 source, installed it, built the package, copied the straight x86_64 config file from SOURCES into the build directory, redid make menuconfig to enable NTFS support, added the # x86_64 back into the .config file, copied .config back to the SOURCES directory and ran rpmbuild -ba --target=x86_64 <spec file> (same as I always do with new kernels), but this time I'm getting this error in the build: Patch #99990 (linux-2.6-rhel-version-h.patch): + patch -p1 -s + perl -p -i -e 's/^SUBLEVEL.*/SUBLEVEL = 18/' Makefile + perl -p -i -e 's/^EXTRAVERSION.*/EXTRAVERSION = -prep/' Makefile + perl -p -i -e 's/^RHEL_MAJOR.*/RHEL_MAJOR = 5/' Makefile + perl -p -i -e 's/^RHEL_MINOR.*/RHEL_MINOR = 2/' Makefile + cp /home/rpmbuild/SOURCES/COPYING.modules Documentation/ + mkdir configs + for cfg in 'kernel-2.6.18-x86_64*.config' + cp -f /home/rpmbuild/SOURCES/kernel-2.6.18-x86_64-debug.config /home/rpmbuild/SOURCES/kernel-2.6.18-x86_64-xen.config /home/rpmbuild/SOURCES/kernel-2.6.18-x86_64.config . + for i in 'kernel-2.6.18-x86_64*.config' + mv kernel-2.6.18-x86_64-debug.config kernel-2.6.18-x86_64-debug.config.tmp + /home/rpmbuild/SOURCES/merge.pl /home/rpmbuild/SOURCES/config-rhel-generic kernel-2.6.18-x86_64-debug.config.tmp + rm kernel-2.6.18-x86_64-debug.config.tmp + for i in 'kernel-2.6.18-x86_64*.config' + mv kernel-2.6.18-x86_64-xen.config kernel-2.6.18-x86_64-xen.config.tmp + /home/rpmbuild/SOURCES/merge.pl /home/rpmbuild/SOURCES/config-rhel-generic kernel-2.6.18-x86_64-xen.config.tmp + rm kernel-2.6.18-x86_64-xen.config.tmp + for i in 'kernel-2.6.18-x86_64*.config' + mv kernel-2.6.18-x86_64.config kernel-2.6.18-x86_64.config.tmp + /home/rpmbuild/SOURCES/merge.pl /home/rpmbuild/SOURCES/config-rhel-generic kernel-2.6.18-x86_64.config.tmp + rm kernel-2.6.18-x86_64.config.tmp + rm -f kernel-2.6.18-i686-kdump.config kernel-2.6.18-x86_64-kdump.config + rm -f kernel-2.6.18-i586.config + rm -f kernel-2.6.18-x86_64-debug.config + for i in '*.config' + mv kernel-2.6.18-x86_64-xen.config .config ++ head -1 .config ++ cut -b 3- + Arch=x86_64 + make ARCH=x86_64 nonint_oldconfig + echo '# x86_64' + cat .config + for i in '*.config' + mv kernel-2.6.18-x86_64.config .config ++ head -1 .config ++ cut -b 3- + Arch=x86_64 + make ARCH=x86_64 nonint_oldconfig CONFIG_MAX_RAW_DEVS make[1]: *** [nonint_oldconfig] Error 1 make: *** [nonint_oldconfig] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.53835 (%prep) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.53835 (%prep) Was there something I needed to tweak in the spec file, other than the build id and a few of the build switches I usually turn off (xen, debug, kdump)?

CentOS as a desktop was Re: Slightly OT
by Donald Buchan 07 Aug '08

07 Aug '08

> OK ... this is silly > > CentOS is an Enterprise distro and works great as a workstation. In > fact, it is just as good as Ubuntu for a desktop. I would argue that a > stable, supported for several year desktop is much better than a distro > that upgrades every 6 months. I have found just that. I was introduced to linux a couple of years ago by way of FC5 (known about it for years, always wanted to migrate, dabbled in RH6 about 8 years ago and dropped it). I was supposed to get CentOS 4.4 but got FC5, allegedly -devel. Big mistake, I had it removed and CentOS 4.4 installed after a couple of months. The stability, the lower number of updates, reduced to effective nil dependency hell (provided that I stuck with the repo stuff, and even then many outside stuff) and long-term support was what attracted me. The 6 month treadmill was one of several issues I had; why spend 6 months installing and fighting with a system, only to have to go through the trouble of reinstalling after 6 months and starting again? However getting my "new" printer (about one year on the market and had it since December 2007) to work on my desktop under 5.2 as well as getting, then keeping keeping wireless on my laptop using a 4 year old PCMCIA card were deal breakers. I currently run 3 computers at home, one on the same box that got the 4.4 a couple of years ago and now upgraded to 4.6. The other two ... I had 4.4 on one and the other is a new acquisition, and installed 5.2 on both, and within a month I had to move to Ubuntu (aaaarrrrgghhhh-lee. I will be moving to F9 soon if things work out, Ubuntu is a strange breed that works, with a consumer experience virtually identical to what I had under CentOS with the exception of stuff that works with no trouble and a few nuances, but ... something rubs me the wrong way. Things like the Ubuntu customizations to the Gnome menus and the fact that the default user is defacto root while root is relegated to uselessness (including not being able to log into its own desktop to take advantage of the gui admin tools!) Long and the short of it, I would rather keep up with CentOS, made a rash decision to use Ubuntu 8.06 since it works and has the saving grace of being LTS, and will look into Fedora 9 since I'd rather be running a(n albeit small) Red Hat farm instead of a mostly Ubuntu/Debian farm. I still agree that CentOS is a robust and highly appropriate desktop. Just getting it to do basic things like wireless and printing (forget easily, just at all) need MAJOR work from upstream. Oh well, I don't pay site licences and CentOS strives for 100% binary compatibility ....

TSPC RPM for CentOS 5
by Darryl Ross 07 Aug '08

07 Aug '08

Hi All, Before I go about building an RPM for TSPC (the IPv6 tunnel setup protocol client), I'm just wondering if someone has already done it? My Googling hasn't turned up anything, and I can't see any packages in the Dag, RpmForge, etc repositories. Regards Darryl

rsyslog and imuxsocks
by Dirk H. Schulz 06 Aug '08

06 Aug '08

Hi folks, I have installed rsyslog and rsyslog-mysql from the base repository, but the loadable module "imuxsocks" seems not to be part of these packages. Does this have a certain reason? And is there any other way to get this module besides compiling rsyslog on my own? Any hint or help is appreciated. Dirk
