IRC telling you to go to mailing list - it's for good reason ....
by Gabriel - IP Guys 31 May '10

31 May '10

Just to answer the aspect of why people in IRC tell you to go to a mailing list – because mailing list answers are more permanent that IRC, and also, it spreads the knowledge of the question, and the answer over a much wider time frame rather than just the two to three sentences that are involved in fixing your situation. It also notifies the mailing list which is generally watched by the devs/patchers/genius(is)/workaround guys/people from other distros/generally smart people – who could probably help you work through the problem, or at least direct you to a page that can. These days people treat IRC like a street market for info, there are no rules other than do not paste more than 3 lines! (pastebin is your friend) and you can say what you like to who you like, and log off, without so much as contributing to the community. … At least by coming to the mailing list, or at least searching the archives, the effort that had previously been exerted to answer the question the first 20 times on the mailing list, will not be wasted. IRC has been around for a long time, but unless the irc server is irc.(project domain name here).org then expect it to be staffed by volunteers and people who may not have the same focus as yourself. IRC is just one of a number of resources. It a good spot for instant relief, (think street hooker), but the mailing list is your wife! *disclaimer* I do not advocate the use of street hookers, nor do I discriminate/have any negative feeling towards against those who do, or indeed are ☺ - I just wanted to make a point! I think I made my point, all the resources are out there on the web, this is open source, we don’t pay for it, be glad with the system that has actually managed to evolve given the fact the only incentive has been to pass on knowledge. --- Latest Article :- The Puppet Module Tool The Puppet Apprentice :- http://puppetnewbie.blogspot.com Follow me on twitter :- http://twitter.com/mritguru Puppet #tags on twitter :- #puppet #puppetforge IRC :- itguru ON irc.freenode.org (feel free to say hi!)

CentOS 5 and seamonkey
by Robert 31 May '10

31 May '10

Has anyone had any success in rebuilding seamonkey 2.0.4 for CentOS 5 (32-bit)? I'm currently running seamonkey-2.0-1 which I rebuilt last November. Sadly, I have no idea where the SRPM originated. I found seamonkey-2.0.4-1.fc12.src.rpm and seamonkey-2.0.4-1.fc12.src.rpm, downloaded and got to 0th base: [rj@madeleine Downloads]$ rpmbuild --rebuild seamonkey-2.0.4-1.fc12.src.rpm Installing seamonkey-2.0.4-1.fc12.src.rpm warning: InstallSourcePackage: Header V3 RSA/SHA256 signature: NOKEY, key ID 57bbccba warning: user mockbuild does not exist - using root warning: group mockbuild does not exist - using root error: unpacking of archive failed on file /home/rj/rpmbuild/SOURCES/find-external-requires;4c000273: cpio: MD5 sum mismatch error: seamonkey-2.0.4-1.fc12.src.rpm cannot be installed So, have md5sum or cpio been changed? Mine should be the latest from CentOS: [rj@madeleine Downloads]$ rpm -q coreutils coreutils-5.97-23.el5_4.2.i386 [rj@madeleine Downloads]$ rpm -q cpio cpio-2.6-23.el5_4.1.i386 Or am I looking at the wrong thing? BTW, the reason I'm after 2.0.4 is that a friend tells me that he's using 2.0.4 under Windows XP and that it does NOT have the problem with the email address completion that I see and that he also saw until he upgraded his. Pointers, clues, URLs and remarks about my sanity are equally welcome at this point.

CentOS with Kernel 2.6.32 built-in
by Adryan Pop 30 May '10

30 May '10

I have a Asus laptop, from the new generation, and my network driver is present in the kernel since version 2.6.32(Jmicron). Is there any CentOS with this kernel? I tried to compile myself, but I failed. Is a bit harder than I thought. Is there any testing version of CentOS or some backports? Thanks

Problem with yum update of device-mapper

28 May '10

I am seeing the following behaviour on all my ix86 CentOS-5.5 hosts: Downloading Packages: (1/2): device-mapper-event-1.02.39-1.el5_5.2.i386.rpm | 20 kB 00:00 (2/2): device-mapper-1.02.39-1.el5_5.2.i386.rpm | 724 kB 00:02 http://centos.mirror.iweb.ca/5.5/updates/i386/RPMS/device-mapper-1.02.39-1.…: [Errno -1] Package does not match intended download Trying other mirror. The step 2 download repeats until the maximum number of mirrors has been tried and then the update fails. I had previously run yum clean all before attempting the update. Can anyone enlighten me as to the cause and remedial action required? The favour of a direct response is requested as I am a digest subscriber. -- *** E-Mail is NOT a SECURE channel *** James B.

metadata cache corruption: cleared -> fixing in progress
by Tru Huynh 28 May '10

28 May '10

Hi, The big mess today in the 5.5/updates tree was caused by a cache corruption in the master CentOS tree during the metadata creation. <tech> createrepo is run with the --cachedir flag. Something went bad :( </tech> The wrong cached metadata for the last updates (see centos-announce mailing list) caused the issue you have all noticed today. We are sorry for that. I initially though that it was a out of sync issue, but I was wrong. The cachedir was cleared, new metadata generated and pushed to the main centos.org server and going down to the public mirrors. All should be back to normal soon. Tru -- Tru Huynh (mirrors, CentOS-3 i386/x86_64 Package Maintenance) http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xBEFA581B

Stop annoying kernel message
by José Christian Iñiguez Bonilla 28 May '10

28 May '10

Hi Everyone! This is my problem: I´m using Nagios tool to monitor my servers with Cent OS 5, and I recently added the script for check nfs. This script makes an rpc request in the server, but every time that script makes this request, I have this message in /var/log/messages: "kernel: svc: unknown version (0)" I´m not sure if this message is only a message or a problem that I have to fix. Could you guys help me to stop this annoying message?? Thanks in advance!
