relatime in plus kernel
by Yuji Tsuchimoto 01 Nov '09

01 Nov '09

Dear CentOS lovers, Is someone interested in the linux-2.6-smarter-relatime.patch for centosplus kernel? This patch solves disk I/O performance dramatically on servers, And recent distributions (fedora9 and later, etc.) and official kernel applies it. RHEL6 may include it, but RHEL5 is not. How about the linux-2.6-smarter-relatime.patch? Best Regards, Yuji

CentOS 5.4: yum-priorities seems to be MIA
by Boris Epstein 01 Nov '09

01 Nov '09

Hi all, I just installed 5.4 on a machine here... All seems running fine, except I decided to put on the extra repositories - and as usual I decided to install yum-priorities (as directed here: http://wiki.centos.org/AdditionalResources/Repositories/RPMForge ) but it seems like this package is nowhere to be found. Does anybody know why this would be? Thanks. Boris.

iptables -d fqdn instead of IP
by Marcus Moeller 01 Nov '09

01 Nov '09

Hi all, does it work to define iptables rules with a fqdn as destination instead of an IP address? Or is it useful to resolve the name first using e.g. nslookup, writing the result to a variable which is then used within the -d statement? Best Regards Marcus

Interrupting Yum Update
by Lee Perez 01 Nov '09

01 Nov '09

Hi All, Quick question, I just finished googling and found the thread that is dealing with the rpmdup_remover.sh script, and thanks to everyone that was involved in this. I followed the following threads: http://www.opensubscriber.com/message/centos@centos.org/11086209.html http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=17… Which lead me to the following link and the script: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=10139&forum=27&p… I started an update at about 5pm on the 30th and here it is 2:30 in the morning on the 31st. I want to kill this update and start over. I usually get around 155 KB/s now I'm getting 455 B/s. I do believe it is the mirror that I am connected to. I just want to make sure that by using the above mentioned script that I am going the right way. Just looking for a little reassurance before I do it. If I don't I don't think this thing will finish until sometime next week :-) and that is a bit long. Thanks!! Lee Perez

5.4 kernel versions?
by Rob Kampen 01 Nov '09

01 Nov '09

Please excuse a possibly dumb question. Prior to the release of CentOS 5.4 I believe two updated 5.4 kernels were released as part of 5.3 2.6.18-164.el5 and 2.6.18-164.2.1.el5 Now that 5.4 is released we have just the 2.6.18-164.el5 kernel. Now the dumb question - what happened to the updated kernel? I now have workstations running 5.4 with the 164.2.1.el5 as they get yum update run regularly, however I do not reboot my servers as often and now find these do not have the later kernel. If some kind soul would please enlighten me..... Rob

how to set default proxy?
by Eugeneapolinary Ju 31 Oct '09

31 Oct '09

hi I know that I could use ssh tunneling: ssh -fND localhost:6000 SOMEBODY(a)192.168.56.5 -p PORTNUMBER to surf the web through another machines internet connection -> I just need to set Firefox to use proxy 6000. But: How can I set that on the client side, to e.g.: ping through the machine with openssh-server? Not just setting Firefox to use port 6000. Is there any method for setting the default proxy in Linux, so that if I use wget, I will download through the ssh tunnel? Thank you

authorized_keys command=""
by happymaster23 31 Oct '09

31 Oct '09

Hello, as I have read manual, if I use in file authorized_keys option command="" with some command, no other commands will be permitted. I have tried it, created authorized_keys2 for root and added there command="rdiff-backup --server" and after that tried to login. Thit command was executed, but I was normally able to supply other comand as root. Can you tell me why? Thank you Martin

Centos 5.4 kernels for NFS4
by Gerhard Schneider 31 Oct '09

31 Oct '09

Do CentOS 5.4 users still have to use the RedHat preliminary kernels (http://people.redhat.com/jlayton/) for getting a NFSv4 safe kernel or have the patches been incorporated into CentosPlus kernels? Or is kernel-2.6.18-164.3.1.el5 somewhere in the queue? Thanks in advance!

HP Proliant ML G6 problem.
by Rafał Radecki 31 Oct '09

31 Oct '09

Hi all. I try to install CentOS 4 x64 on HP Proliant ML G6. Anaconda doesn't correctly recognise the DVD-RW drive despite the fact that the installation starts from it. Also when I choose network (HTTP/FTP) installation type the ethernet card isn't correctly recognized. On HP website there aren't any drivers to use during installation only rpms and source rpms which (as I think) are useless at install time and can be used only when the system is installed. I also tried CentOS 5 x64 and there are no problems with my hardware then, the installation is ok. DVD-RW is: HP Super Multi DVD Rewriter GH40L E2C NIC is: HP NC107i Integrated PCI Express Gigabit Server Adapter What should I do? Where to start from to solve the problem? With regards, R.

Driver compilation howto.
by Rafał Radecki 31 Oct '09

31 Oct '09

Hi all. I currently have to add some drivers during the installation process for CentOS 4.4 (I mus use this release). As I've heard I need first to compile the drivers under the same kernel which will be used during install time. What should I do then? Could anyone provide a link to an appropriate howto? With regards, R.
