[CentOS] [CSL #351425] perfctr-enabled C5 kernel anyone?
Hi all: We have a user who needs to do some work with PAPI, which requires the perfctr patch applied to the kernel proper. Before I do that work here, I wanted to ask the list if anyone knows of a repo where such kernels are available? Also, if anyone has gone down this route and has helpful hints, perspectives, horror stories, etc., I would covet that information also.

For user accounts, changing one strong password for another gains you nothing, and may cause people to start writing things down, or choosing trivial passwords which still meet the password strength criteria, or whatever, actually weakening security. However, if you have admins who come into or leave employment, changing privileged account passwords (read: root or equiv) is a necessary activity.

I remember awhile back there was much weeping and gnashing of teeth because updates to tzdata _didn't_ update /etc/localtime. I would hope they would have fixed that by now. Part of our configuration engine makes sure that /etc/localtime is up to date with the appropriate /usr/share/zoneinfo/... file.

[CentOS] xfs 0.4-1 kernel modules CentOS 4/5
Is anyone else having difficulty with the kmod-xfs-*0.4-1* rpms from the centosplus repositories? For several years I have used a patched anaconda to get xfs file systems into the initial install for non-root file systems. With the 0.4-1 rpms, The subsequent reboot immediately reports file system xfs errors, and the system is unusable. I'm finding this with both CentOS 4 and CentOS 5. A rebuild of the old kernel-module-xfs* rpms (the version 0.2-1 rpms) for CentOS 4 for the new kernel (55.0.2.EL) works fine. I've tried both the standard kernel (with rebuilt 0.4-1 rpms), and the centosplus kernels for CentOS 4. I haven't yet tried to rebuild the 0.2-1 xfs modules with CentOS 5. Anyone else have experience with the new xfs modules? Thanks much. Dave Thompson UW-Madison ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I believe that as long as the interfaces are connected to different networks, there is no problem having the same MAC address. Connecting two NICs with the same mac address to the same network would be a Bad Thing (tm), as network switches would be confused about where to send packets destined for the MAC address in question. Years ago, Sun workstations with multiple NICs would always have the same MAC address for all the NICs. That being said, it does seem less than helpful on a modern motherboard. I just wanted to point out that it _may_ be an intentional design issue (though I agree a bad one).
