Crontab problem
by Jennifer Botten 05 Oct '10

05 Oct '10

Hi, I seem to have a problem with crontab. I am running CentOS 5.5. If I add my bakup scripts into crontab they take very long to run. If I run my scripts manually they run 100%. I have also tried vixiecron, same issue. Any ideas? Thanks Jenny

Python resource module returns just zeros
by Adam Tauno Williams 04 Oct '10

04 Oct '10

I'm using a call to the resource module's getrusage method. On openSUSE this works, on CentOS [python26-2.6.5-3.el5] it 'works' but just returns zeros for the memory utilization values. resource.getrusage(resource.RUSAGE_SELF).ru_maxrss openSUSE: returns 5512 CentOS: returns 0 Anyone know what condition causes this? Or is there a better / more-reliable way to check memory utilization of the current process [from python]? -- Adam Tauno Williams <awilliam(a)whitemice.org> LPIC-1, Novell CLA <http://www.whitemiceconsulting.com> OpenGroupware, Cyrus IMAPd, Postfix, OpenLDAP, Samba

how many people still use NIS?
by Boris Epstein 04 Oct '10

04 Oct '10

Hello listmates, I have discovered a very strange SFTP problem which I can not connect to anything but NIS thus far. See here: http://www.linuxquestions.org/questions/linux-server-73/sftp-seems-to-fail-… http://readlist.com/lists/suse.com/suse-linux-e/38/193419.html Hence the question: is NIS (YP) still in use much anywhere for authentication? Thanks. Boris.

Format details for a raid partition....
by Tom Bishop 04 Oct '10

04 Oct '10

So I have been playing with a RAID 10 f2 ( 2 disks far layout) setup...thanks for all of the advice..Now I am playing with the format and want to make sure I have it setup the best that I can, my raid was built using the raid 10 option with 2 disks with the layout=far, chunk size 512....now I read all of the docs I could find about format and stride and stripe size and this is what i came up with... mkfs -t ext4 -E stride=128,stripe-width=32 /dev/md0 Someone let meknow if this looks right, but since i only have two disks to get my stride 512/4k=128 and then to get my stripe 2/2*128/4=32 Does that look right and if not let me know but more important how to obtain the right number so I can do it correctly in the future...Thanks.

sata AHCI controllers (real and virtual)
by drew einhorn 04 Oct '10

04 Oct '10

I saw something somewhere about AHCI support requiring kernel 2.6.19 or later. But the current CentOS/RHEL stable kernels are 2.6.18 I'm trying to run CentOS/RHEL in a VirtualBox vm, which by default creates sata virtual disks with an AHCI virtual controller. These virtual machines are quite unstable, and I'm wondering if the AHCI virtual controller is the problem. I do have a real physical AHCI controller and I'm wondering if I should try it on a CentOS/RHEL 5.5 box, or if I should wait for RHEL/CentOS 6, before even attempting it. -- Drew Einhorn "You can see a lot by just looking." -- Yogi Berra

best filesystem for a webserver
by Roland RoLaNd 04 Oct '10

04 Oct '10

Dear all, i'm setting up a new machine to handle a webserver with mysql web directory contains alot of small files and database is around 15 GB i've did a bit research, read alot of articles.. mainly i came up with the understanding that: EXT3 is the set it and forget it kind of filesystem. and reiserFS is the best choice for small files though there's a bigger risk of data loss upon power failure (better solved in ext3) any advice on this matter? or any other filesystem you advise me to use on a production system? thanks

help with spec file
by Tim Dunphy 03 Oct '10

03 Oct '10

I am attempting to learn how to build my own rpms. I found a good tutorial online but it is a bit out of date (2007). Here it is: http://www.rpm-based.org/how-to-create-rpm-package At any rate, the package it uses is of course old and I found a newer version of one to test with. The tutorial uses a program called 'subtitleeditor' which when it was written was at version 0.20.0alpha4. The current version is at 0.37.1 and is available here: http://home.gna.org/subtitleeditor/ I have come up with a spec file for the current version that _mostly_ works... ============================================ Summary: Subtitle editor Name: subtitleeditor Version: 0.37.1 Release: 1.rb7 License: GPL Group: Applications/Multimedia URL: http://kitone.free.fr/subtitleeditor/ Source: http://kitone.free.fr/subtitleeditor/files/subtitleeditor-%{version}.tar.gz BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root #Patch: gtk_update_icon_cache.patch BuildRequires: gstreamer-plugins-base-devel, gtk2-devel, gtkmm24-devel, libglademm24-devel BuildRequires: gstreamer-devel, pcre-devel, libxml++-devel, enchant-devel, iso-codes-devel Packager: bluethundr %description Subtitle Editor is a GTK+2 tool to edit subtitles for GNU/*. It can be used for new subtitles or as a tool to transform, edit, correct and refine existing subtitle. This program also shows sound waves, which makes it easier to synchronise subtitles to voices. Subtitle Editor is free software released under the GNU General Public License (GPL). %prep %setup -q #%patch -p1 -b .buildroot %build %configure --disable-debug %{__make} %install %{__rm} -rf %{buildroot} %makeinstall %find_lang %{name} %clean %{__rm} -rf %{buildroot} %files -f %{name}.lang %defattr(-, root, root, 0755) %doc AUTHORS ChangeLog INSTALL NEWS TODO README COPYING %{_bindir}/subtitleeditor %{_datadir}/subtitleeditor/ %{_datadir}/icons/hicolor/* %exclude %{_datadir}/icons/hicolor/icon-theme.cache %{_datadir}/applications/subtitleeditor.desktop %changelog * Sat Oct 2 2010 - bluethundr At gm4il d00t com 0.37.1 - Initial release. ====================================================== And with the prereqs installed I get mostly through the build. But I get hung up here: ======================================================= checking for XML::Parser... ok checking for i686-redhat-linux-gnu-pkg-config... no checking for pkg-config... /usr/bin/pkg-config checking pkg-config is at least version 0.9.0... yes checking for GTKMM... configure: error: Package requirements (gtkmm-2.4 >= 2.14 glibmm-2.4 >= 2.16.3) were not met: Requested 'gtkmm-2.4 >= 2.14' but version of gtkmm is 2.10.10 Requested 'glibmm-2.4 >= 2.16.3' but version of GLibmm is 2.12.10 Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GTKMM_CFLAGS and GTKMM_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. error: Bad exit status from /var/tmp/rpm-tmp.90098 (%build) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.90098 (%build) ====================================================== It seems to be looking for gtkmm-2.4 at version greater than 2.14 and glibmm-2.4 at a version greater than 2.16.3. Yet I have looked for rpm's of these files at those levels and I find none later than the ones installed. I think the solution may lie here: Alternatively, you may set the environment variables GTKMM_CFLAGS and GTKMM_LIBS to avoid the need to call pkg-config. I understand I am novice at these matters, but I am unsure of how to set these variables and would appreciate a pointer on how to do that. I would appreciate it if I could get some help with this problem. Thanks in advance! Thanks
