Why are all repos < 5.6 listed?
by Keith Roberts 23 Jul '11

23 Jul '11

Greetings all. I just enabled all repos on my system, to enable me to find a particular package. This is the first time I have noticed all the Centos repos < 5.6 being listed. Is this a new feature, to include all repos pre 5.6 now? Here's the output of the aforementioned yum command - sorry it's a little bit long: [root@karsites ~]# yum --enablerepo '*' --disablerepo 'c5-media' info textpattern Loaded plugins: fastestmirror, filter-data, keys, list-data, priorities Loading mirror speeds from cached hostfile * addons: mirror.netrino.co.uk * base: centos.mirror.evertje.net * centosplus: mirror.netrino.co.uk * contrib: centos.mirror.evertje.net * epel: mirrors.coreix.net * epel-debuginfo: mirrors.coreix.net * epel-source: mirrors.coreix.net * epel-testing: mirrors.coreix.net * epel-testing-debuginfo: mirrors.coreix.net * epel-testing-source: mirrors.coreix.net * extras: centos.mirror.evertje.net * remi: iut-info.univ-reims.fr * rpmforge: apt.sw.be * rpmforge-extras: apt.sw.be * rpmforge-testing: apt.sw.be * updates: mirror.netrino.co.uk C5.0-base | 1.1 kB 00:00 C5.0-base/primary | 798 kB 00:01 C5.0-base 2334/2334 C5.0-centosplus | 951 B 00:00 C5.0-centosplus/primary | 90 kB 00:00 C5.0-centosplus 134/134 C5.0-extras | 1.1 kB 00:00 C5.0-extras/primary | 77 kB 00:00 C5.0-extras 302/302 C5.0-updates | 951 B 00:00 C5.0-updates/primary | 352 kB 00:00 C5.0-updates 764/764 C5.1-base | 1.1 kB 00:00 C5.1-base/primary | 834 kB 00:01 C5.1-base 2400/2400 C5.1-centosplus | 951 B 00:00 C5.1-centosplus/primary | 73 kB 00:00 C5.1-centosplus 174/174 C5.1-extras | 1.1 kB 00:00 C5.1-extras/primary | 113 kB 00:00 C5.1-extras 421/421 C5.1-updates | 951 B 00:00 C5.1-updates/primary | 278 kB 00:00 C5.1-updates 502/502 C5.2-base | 1.1 kB 00:00 C5.2-base/primary | 853 kB 00:01 C5.2-base 2458/2458 C5.2-centosplus | 951 B 00:00 C5.2-centosplus/primary | 72 kB 00:00 C5.2-centosplus 119/119 C5.2-extras | 1.1 kB 00:00 C5.2-extras/primary | 90 kB 00:00 C5.2-extras 298/298 C5.2-updates | 951 B 00:00 C5.2-updates/primary | 374 kB 00:00 C5.2-updates 805/805 C5.3-base | 1.1 kB 00:00 C5.3-base/primary | 878 kB 00:01 C5.3-base 2508/2508 C5.3-centosplus | 951 B 00:00 C5.3-centosplus/primary | 115 kB 00:00 C5.3-centosplus 151/151 C5.3-extras | 1.1 kB 00:00 C5.3-extras/primary | 107 kB 00:00 C5.3-extras 324/324 C5.3-updates | 951 B 00:00 C5.3-updates/primary | 353 kB 00:00 C5.3-updates 528/528 C5.4-base | 2.1 kB 00:00 C5.4-base/primary_db | 1.6 MB 00:02 C5.4-centosplus | 1.9 kB 00:00 C5.4-centosplus/primary_db | 184 kB 00:00 C5.4-extras | 2.1 kB 00:00 C5.4-extras/primary_db | 180 kB 00:00 C5.4-updates | 1.9 kB 00:00 C5.4-updates/primary_db | 616 kB 00:00 C5.5-base | 2.1 kB 00:00 C5.5-base/primary_db | 1.6 MB 00:03 C5.5-centosplus | 1.9 kB 00:00 C5.5-centosplus/primary_db | 127 kB 00:00 C5.5-extras | 2.1 kB 00:00 C5.5-extras/primary_db | 183 kB 00:00 C5.5-updates | 1.9 kB 00:00 C5.5-updates/primary_db | 911 kB 00:01 addons | 951 B 00:00 atrpms | 2.6 kB 00:00 atrpms/primary_db | 1.3 MB 00:02 atrpms-bleeding | 2.9 kB 00:00 atrpms-bleeding/primary_db | 26 kB 00:00 atrpms-bleeding-debuginfo | 2.6 kB 00:00 atrpms-bleeding-debuginfo/primary_db | 6.6 kB 00:00 atrpms-bleeding-source | 2.6 kB 00:00 atrpms-bleeding-source/primary_db | 7.7 kB 00:00 atrpms-debuginfo | 2.6 kB 00:00 atrpms-debuginfo/primary_db | 219 kB 00:00 atrpms-source | 2.6 kB 00:00 atrpms-source/primary_db | 228 kB 00:00 atrpms-testing | 3.0 kB 00:00 atrpms-testing/primary_db | 166 kB 00:00 atrpms-testing-debuginfo | 2.6 kB 00:00 atrpms-testing-debuginfo/primary_db | 31 kB 00:00 atrpms-testing-source | 2.6 kB 00:00 atrpms-testing-source/primary_db | 27 kB 00:00 base | 1.1 kB 00:00 centosplus | 1.9 kB 00:00 centosplus/primary_db | 99 kB 00:00 contrib | 951 B 00:00 debug | 951 B 00:00 debug/primary | 859 kB 00:02 debug 3390/3390 epel | 3.7 kB 00:00 epel-debuginfo | 2.6 kB 00:00 epel-debuginfo/primary_db | 488 kB 00:00 epel-source | 2.9 kB 00:00 epel-source/primary_db | 935 kB 00:01 epel-testing | 3.7 kB 00:00 epel-testing/primary_db | 180 kB 00:00 epel-testing-debuginfo | 2.6 kB 00:00 epel-testing-debuginfo/primary_db | 25 kB 00:00 epel-testing-source | 2.8 kB 00:00 epel-testing-source/primary_db | 47 kB 00:00 extras | 2.1 kB 00:00 remi | 2.5 kB 00:00 remi/primary_db | 259 kB 00:00 remi-test | 2.5 kB 00:00 remi-test/primary_db | 38 kB 00:00 rpmforge | 975 B 00:00 rpmforge-extras | 975 B 00:00 rpmforge-extras/primary | 60 kB 00:00 rpmforge-extras 158/158 rpmforge-testing | 975 B 00:00 rpmforge-testing/primary | 132 kB 00:00 rpmforge-testing 413/413 updates | 1.9 kB 00:00 Excluding Packages in global exclude list Finished 24300 packages excluded due to repository priority protections Error: No matching Packages to list Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

nouveau driver one centos 6
by Jerry Geis 23 Jul '11

23 Jul '11

I "wish" to not load the or even install the nouveau driver by default. I want to use the NVIDIA binary driver. I have tried a number of things: 1) in my kickstart package section add the line: -xorg-x11-drv-nouveau This did not work - it was still installed. 2) use the nvidia installer and it asks to create a modprobe.conf file to blacklist the driver. I said yes thats what I want. I verified the file being present and rebooted. The driver is still loaded "lsmod | grep nou" still showed it present. 3) I tried "rpm -e xorg-x11-drv-nouveau --nodeps". This seeming worked however the files for nouveau were still present. find / | grep nouveau showed driver files and more.... So - anyone know how to get this off of my machine??? I thought the "-" in the kickstart package section would work, but no. Thanks so much for any thoughts. jerry

CentOS 6.0 chkconfig strange behavior
by Jerry Moore 22 Jul '11

22 Jul '11

Hi, I'm noticing some strangeness with chkconfig on CentOS 6.0 and was looking for a bit of advice. It appears that chkconfig is re sequencing or re ordering the start priority of various services when turning on a service using chkconfig. Example is the network service. Under normal circumstances network is set to start at S10. However when I add something like snmpd and invoke chkconfig snmpd on it will change network to S81. Which fouls up some of my other services that look for config files on NFS shares. Testing this issue with the snmpd service I removed $network from Required-Start which did nothing. The only solution I've found is to remove the entire BEGIN INIT INFO to END INIT INFO section. Once that is removed it no longer changes the network startup priority when enabling the snmpd service. Seems to me that you'd want network started before snmpd. So why chkconfig wants to re arrange it to start after snmpd which defaults to S50 is beyond me. So why would it do that? Did I miss some documentation or something? :-) Thanks in advance for any assistance! --Jerry

ext4 in CentOS 5.6?
by PJ 22 Jul '11

22 Jul '11

I'm sure many are running ext4 FS's in production, but just want to be re-assured that there are not currently any major issues before starting a new project that looks like it will be using ext4. I've previously been using xfs but the software for this project requires ext3/ext4. I'm always very cautious before jumping onto a new FS, (new in the sense it is officially supported now) Thanks in advance!

Hi, Jerry Try appending 'rdblacklist=nouveau' to the kernel line in grub.conf (and keep the blackist in modules.conf) - install CentOS and reboot as usual - preempt booting at the grub menu and append 'rdblacklist=nouveau 3' to the kernel line to disable nouveau and start up in init 3 - install the Nvidia binary driver. Optionally, do a yum upgrade, reboot back to init 3 and build the driver on the latest kernel - edit grub.conf and remove the '3' and reboot again Nouveau will now stop loading and use your nvidia driver cheers, - cal On 21/07/11 13:08, Jerry Geis wrote: > I "wish" to not load the or even install the nouveau driver by default. > I want to use the NVIDIA binary driver. > > I have tried a number of things: > > 1) in my kickstart package section add the line: > -xorg-x11-drv-nouveau > > This did not work - it was still installed. > > 2) use the nvidia installer and it asks to create a modprobe.conf file > to blacklist > the driver.

Strange problem with LVM, device-mapper, and software RAID...

Running on a up-to-date CentOS 5.6 x86_64 machine: [heller@ravel ~]$ uname -a Linux ravel.60villagedrive 2.6.18-238.19.1.el5 #1 SMP Fri Jul 15 07:31:24 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux with a TYAN Computer Corp S4881 motherboard, which has a nVidia 4 channel SATA controller. It also has a Marvell Technology Group Ltd. 88SX7042 PCI-e 4-port SATA-II (rev 02). This machine has a 120G SATA system disk on the motherboard controller as the system disk: [heller@ravel ~]$ sudo /sbin/fdisk -l /dev/sda Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 125 1004031 83 Linux /dev/sda2 126 14593 116214210 8e Linux LVM /dev/sda1 is /boot and /dev/sda2 is a LVM Volume group (named "RavelSystem") with two logical volumes (named "root" and "swap"), containing the root file system and a base 1G swap area.

package recommendation for video conferencing
by Geoff Galitz 22 Jul '11

22 Jul '11

Hi. We have a need for a video conferencing package with the following specs: - cross platform client support (Linux, Mac, Win) - server side runs on Centos 5 and later with easy package installation routine (e.g. RPM) - can host a teleconfernce with no users connected (IOW, it can wait for users to connect at any time) - supports mulitple users per video conference Recommendations? Thanks.
