I guess it comes down to diminishing returns. PAE has been around for a few years and it may not be worth the effort for that prominent vendor to provide support for 5 year old, non-server systems that may be just fractions of their market. However, it's *just* a kernel... Kernels are relatively easy to build and don't necessarily affect much in the user space. You may be able to take the CentOS image, once it's ready, then rebuild with a non-PAE kernel. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Your question is not very clear. Do you mean that you have just a local directory of RPMS or that you maintain a local repo? If just a directory then you may want to read: http://wiki.centos.org/HowTos/CreateLocalRepos http://wiki.centos.org/HowTos/CreateLocalMirror In either case, it you want to see what updates are available from a particular repo, say reponame: yum --disablerepo \* --enablerepo reponame check-update You could then download and put RPMS in your local repo as desired.

The simplest answer is that yum deals with all that. If you set up a local repo mirror, then that machine should share out that repo directory via http or ftp. You would sync that with an upline mirror, either via ftp or rsync. Then on the worker nodes, you would create a custom repo file in /etc/yum.repos.d pointing to your local repository. Then the worker nodes could just run a yum update and they would get all the updates they need. It will do all the version checking, and all you have to worry about is keeping your server's local mirror up to date. -- Spiro Harvey Knossos Networks Ltd 021-295-1923 www.knossos.net.nz signature.asc Description: PGP signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thanks it helps! but a little more bit of info^Whints could help even more: lets say that on the server i do this stuff (and where is this dir from which nodes are installed) everything is up to date.. (and worker nodes are NOT updated) and i dont want to ask nodes do give me an rpm -qa.. how can a make a diff (comparing versions) between rpms form local directory and update repo? (other than take the rpm name from dir; strip name and version ; search in update repo the rpm name ; compare version , if newer download rpm ) Why don't you just do the 'yum update' on each box and let it figure out and get what is newer itself? -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] update of rpm directory
If I understand this correctly then you want to update
the LOCAL RPM files to the latest version?
I am not sure but you could try yumdownloader
with some kind of bash script:
for f in `ls -1 *rpm`; do
echo Working on file: $f
rpm=${f##*/}
name=${rpm%%-[0-9]*}
echo The name of the rpm: $name
yumdownloader $name
done
This is NOT tested but you could give it a try!

[CentOS] release of 5.5? (filesystem troubles)
hi guys, is there an estimate when centos 5.5 will be released? I'm sitting on needles here, because since I moved my 4*1.5TB raid5 from an asus to an intel D510 mainboard I encounter bug the described here: https://bugzilla.redhat.com/show_bug.cgi?id=512552 short version: running xfs on top of a raid5 under heavy load causes corrupted data to be read and the filesystem shutting down occasionally. version 5.5 should solve this problem. if 5.5 is just a few days away I'll keep waiting, but if it takes much longer I'll need to work around this problem like going back to the old mainboard, compiling the kernel myself, switching to ext3 - none of which I'm eager to do. cu ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] upgrading to a minor release 4.1 to 4.2
Hi, I need to upgrade a system running 4.1 to 4.2, but before I do I want to list out all the packages that will be updated/installed/removed. I can run up2date -l to get a list of updates but does that show packages that need to be installed and removed as well or just the updates? Second, how would I go about upgrading 4.1 to 4.2 instead of 4.8 (i.e. latest update). Unfortunately I don't have access to centos 4.x at the moment.and googling just centos 4.1 to 4.2 is not bringing up relevant information.

Yes, they do, but I have no idea what that has to do with your
suggestion to use -exec. If you had suggested eliminating the use of
-print as redundant, your suggestion would be merely inefficient rather
than a non sequitur.
you could do
find /etc -type f -exec grep -l ip rule {} \;
You could, but that would run grep once for each file where xargs will
run grep the minimum number of times. Using xargs is substantially faster.
Having said that, I see that find has an option of which I was
previously unaware. If you use the '+' character instead of the ';', it
will behave more or less the same way that xargs does:
find /etc/ -type f -exec grep ip rule {} +
