Re: [asterisk-users] Centos kernel 34 vs. 42?
I'm now running kernel-2.6.9-42.0.3.EL Not really an answer to your question, but I found out all kernels above 2.6.16 do a better job on asterisk systems then the ones before that. No idea how this is possible as I'm in no way familiar with the inner workings of the linux kernel, but I found out after upgrading one system and because it was better there I upgraded a lot of other boxes and they all became better. Maybe you can get a newer kernel on centos then the 2.6.9 Possibly, but I would have to start worrying about kernel configs, compiling the lot and solving the problem of the box no longer being able to boot the kernel :) I looked for CentOS repo's but cannot find one that will throw a plain vanilla kernel my way. There's only a centos plus kernel but these are basically the same as the original kernels just with some filesystems enabled. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

RHEL/CentOS is based on a set kernel version with minimal changes, backporting required fixes/security updates only as necessary. Red Hat's focus with RHEL is 7 years of SLAs with no ABI changes, period - unlike Fedora Core (or Red Hat Linux before it for that matter - which did co-exist with RHEL for 2 years before the trademark change). There's only a centos plus kernel but these are basically the same as the original kernels just with some filesystems enabled. As I hinted above, the changes are just significant enough that Red Hat only backports, to the anal power when it comes to RHEL. And although Fedora Core/Development would be a good start for an updated kernel (far vanilla where countless things would break), there is so much that has changed in the toolchain and user-space of Fedora Core 4-6 that offers a 2.6.16+ release that many people probably haven't bothered. Especially since most people run RHEL/CentOS for its longevity and unchanging ABI/backports approach to an almost anal-level. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [asterisk-users] Centos kernel 34 vs. 42?
Hi, I like Centos as a basic platform, but I always then upgrade the kernel to the latest stable release from kernel.org The latest ones are using Centos 4.4 x86_64 with kernel 2.6.18 For simplicity, I always start with the .config from the original Centos kernel. My install sequence is: Untar the kernel source in /usr/src/kernels ln -s /usr/src/kernels/linux-2.6.18 /usr/src/linux (changing 2.6.18 to the version in use...) cd to /usr/src/linux do 'make mrproper' to clean out any leftover garbage. Older kernel versions often would not build if you missed this step, so I do it by habit now. Copy the .config file from the last installed Centos kernel directory (under /usr/src/kernels/2.6.) to /usr/src/linux Still in /usr/src/linux, do 'make oldconfig' and just press enter all the way through. This should give you a new kernel config matching the Centos distribution. (If you need anything other than the standard Centos kernel config, make changes here) Then do:- make make modules make modules_install make install If everything builds OK, reboot and get ready to select the new kernel as the Grub menu appears. If it all boots OK, you can edit /etc/grub.conf and change the default line to 0 so the new kernel is booted in future. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bryan J.
