CentOS and Scientific Linux Cern installations with FAI
by lange＠fai-project.org 19 Sep '11

19 Sep '11

I'm very happy to announce, that FAI (Fully automatic Installation) now can install and configure CentOS and Scientific Linux Cern (SLC). You can use a Debian FAI server for installing CentOS version 5 and 6 or SLC 5 and 6. As an example I've also built a FAI multi-distribution CD which installs those three different Linux distributions with different configurations. Get this ISO image from http://fai-project.org/fai-cd/ This installation is very quick. I've done a CentOS 6.0 installation (with graphical desktop) in 199 seconds (in a kvm instance on a quad-core 3.2GHz, hard disk in RAM) and it only needs 490 seconds on the real hardware when installing from CD. A short description how to install CentOS or SLC via network from your FAI server is described in this mail: https://lists.uni-koeln.de/pipermail/linux-fai/2011-September/009243.html Feedback is always welcome. Please send your feedback to the linux-fai mailing list https://lists.uni-koeln.de/mailman/listinfo/linux-fai/ Best regards, Thomas, in behalf of the FAI team About FAI: FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large infrastructures and clusters. Compared to kickstart, FAI is more flexible and includes a powerfull class mechanism to build a configuration from multiple building blocks. It also includes the features of cobbler. The project was started in 1999 for the Debian distribution. Later Ubuntu support was added and some time ago we start adding RPM support.

javaWS under firefox on CentOS 5.6 fails to launch sound
by Rob Kampen 19 Sep '11

19 Sep '11

Hi List, Before I spend hours chasing this - my initial google search seems to indicate that javaWS and JNLP apps with sound do not work on CentOS systems. The developer's website says they support :- *Linux* *Supported OS’s and recommended versions of Java* * Linux o openSUSE 11 (64 bit with 64 bit JVM) o Ubuntu 9.10 (64 bit with 64 bit JVM) * Pentium III 1 GHz processor * Sun Java 1.5.0_17 or Sun Java 1.6.0_12 or greater is recommended I have Oracle's java v1.6.0_26 installed - the java app opens up and appears to be functioning fine, however the wizard for setting up the sound, even though it recognizes my sound card fails to actually play any sound. Running latest 5.7 [rkampen@robsws ~]$ uname -a Linux robsws.ndgonline.net 2.6.18-238.19.1.el5.centos.plus #1 SMP Mon Jul 18 10:05:09 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux [rkampen@robsws ~]$ rpm -qa |grep firefox firefox-3.6.18-1.el5.centos.x86_64 Sound from within other browser based apps (flash etc) work just fine. Anyone got a javaWS with sound application working on CentOS? TIA - Rob

Depsolving errors whilst upgrading Centos 5.6 -> 5.7
by Dave Cross 18 Sep '11

18 Sep '11

I have a dedicated server from 1&1 (http://1and1.co.uk/) A 'yum list updates' today showed me that the 5.7 update was available (it's probably been there for a while, I don't check that often). But running 'yum update' gives the following error: Running rpm_check_debug ERROR with rpm_check_debug vs depsolve: kernel(rhel5_fs_proc_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_arch_x86_64_kernel_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_fs_partitions_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_vmlinux_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_kernel_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_fs_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_drivers_xen_core_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_block_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_kernel_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_security_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_block_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_kernel_module_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_fs_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_mm_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_lib_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_mm_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 Complete! (1, [u'Please report this error in http://bugs.centos.org/set_project.php?project_id=16&ref=http://bugs.centos…']) I haven't reported the bug yet. I thought I'd see if anyone here had seen anything similar first. Cheers, Dave... -- Dave Cross :: dave(a)dave.org.uk http://dave.org.uk/ @davorg

centos product specification
by Janez Kosmrlj 18 Sep '11

18 Sep '11

The page http://www.centos.org/product.html has product specifications for all centos releases except for centos6. Is there a reason why or did the site maintainers just forget about it.

centos-release 5.7 srpm where?
by me＠tdiehl.org 18 Sep '11

18 Sep '11

Hi, Is the centos-release srpm for 5.7 available anywhere. I have looked at several mirrors but no srpms are to be found. I realize everyone is busy but it would be nice to have at least the srpms that were specific to the centos project with the release. Regards, -- Tom me(a)tdiehl.org Spamtrap address me123(a)tdiehl.org

My update went very well. booted right back up an everthing seems to be working--except... for some reason it overwrote my sendmail.cf rather than dropping in a sendmail.cf.rpmnew as it has done in the past, so after several hours I noticed I wasn't getting any incoming email. after a little flailing this morning (not having yet had any caffeine) I realized I should look at that. copied my version in, bounced sendmail and off to the races!

Just wanted to thank everyone for helping me get my new machine up and running. I thought I had bought a boat anchor. Not sure what's up with my DVD drive on my 5.7 machine but I will be phasing/retiring it out over the next few days. Again thanks for your help and most of all your patience. Eddie

OT : ARIN Apologies .....
by Always Learning 16 Sep '11

16 Sep '11

For those who use Centos and have problems with ARIN, here is today's apology from ARIN's Chief Engineer Andy Newton posted on ARIN-Tech. Follow-ups, if any, off-list please. Thank you. Paul -------------------------------------- All, We appreciate your patience and willingness to work with us through issues and questions that have arisen with regard to Reg-RWS, our RESTful provisioning and resource management interface. We recognize that our current documentation is deficient, and we are working to correct that problem. Poor or inadequate documentation can be frustrating, and for that we apologize. While the Reg-RWS documentation addresses specific method calls and payloads, there is no good reference to the broader ARIN business rules nor how they apply to the RESTful interface or any of the other ARIN systems. We are working to address this gap. Again, thank you for your patience and willingness to work through questions and issues. Andy Newton Chief Engineer, ARIN
