Loading pre-built for Red Hat kernel modules
by Ross McKerchar 20 Aug '10

20 Aug '10

Hi Guys, I have a product which requires it's own kernel module. The vendor provides pre-built kernel modules that are compiled against the stock Red Hat kernels but the product does not successfully identify and load these binary modules on my Cent OS machines. I'm in a discussion with the vendor about fixing this so that the product successfully identifies the Red Hat modules as compatible. However we're not sure if these binary modules will indeed be 100% compatible with the corresponding Cent OS kernel for any given version. The concern was that tiny differences between the kernels, say, the name of the build host, could change the address of a data structure in the kernel which the pre-built module attempts to use. Does this sound like a valid concern? Where does the attempt to provide 100% binary compatibility end? The source for these kernel modules is actually available but I am trying to avoid having to build custom modules. Thanks for your help! -ross

EOL plans for C3
by Karanbir Singh 20 Aug '10

20 Aug '10

hi Guys, CentOS-3 goes EOL in about 3 months. I was thinking we should do a couple of things for this milestone : 1) Setup and run an education campaign to inform users about this. 2) Put together some documents that clearly lay down the options that users have at this point, and going forward ( Migration options, upgrade paths, virtualised containers etc ) 3) Put together some scripts that might help people with various options from point-2. Of-course, doing some of (2) and (3) before (1) would make (1) more effective. So, at this time - is there anyone who wants to step forward to take this task up as co-ordinator and lead ? - KB

If we decide to do this, I guess we should start identifying those packages that replace base, or require packages that replace base. -- -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [Any errors in spelling, tact or fact are transmission errors]

wine 1.2 packages
by Janez Kosmrlj 12 Aug '10

12 Aug '10

Hi there, I made wine 1.2 packages for centos. I would like to share them but i don't have a public repository. Is there a place, where i could upload this packages. Maybe someone else would need them too. The packages are built to my needs, so they don't have winetricks or desktop integration, but they work. Regards Janez

I cannot connect to www.centos.org and related sites. It was noticed that access to the forums has been very slow today. Now the site is totally inaccessible. Akemi

Sun May 02 2010 Jiri Pirko <jpirko(a)redhat.com> [2.6.18-194.3.1.el5] Well that one you have. Why do you have it? Because I guess an @CentOS.org Hat decided to build that one while all the other ones were plain out skipped in-between? My ohh my the Heart and Soul was forgotten. All of 4 - FOUR of them. Effectively your stuck with the one you got that works or you have to learn to build your own from the red hat sources. > If I just build kernels from the Linux archives, would those just work > as-is under CentOS? I haven't actually done that in a while, but if > it's moderately safe using the "standard" spec files.... Maybe so be carefull. So insightfully what I do for my precious customers on CentOS is I actually build the updates from the RH Sources to keep them happy because some do like to plunder about when are updates coming out. Maybe the cache directory eatted them up? John

a strange (new?) feature in rhel-6
by Farkas Levente 31 Jul '10

31 Jul '10

hi, i'm just accidentally recognize that on rhel-6: ---------------------------------------------- # rpm -qpi rhnsd-4.9.3-2.el6.x86_64.rpm warning: rhnsd-4.9.3-2.el6.x86_64.rpm: Header V3 RSA/SHA256 signature: NOKEY, key ID f21541eb Name : rhnsd Relocations: (not relocatable) Version : 4.9.3 Vendor: Red Hat, Inc. Release : 2.el6 Build Date: Wed 24 Mar 2010 03:11:14 PM CET Install Date: (not installed) Build Host: ls20-bc2-13.build.redhat.com Group : System Environment/Base Source RPM: rhnsd-4.9.3-2.el6.src.rpm Size : 92865 License: GPLv2 Signature : RSA/8, Tue 20 Apr 2010 07:50:37 PM CEST, Key ID 938a80caf21541eb Packager : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla> URL : https://fedorahosted.org/spacewalk Summary : CentOS Network query daemon Description : The CentOS Update Agent that automatically queries the CentOS Network servers and determines which packages need to be updated on your machine, and runs any actions. ---------------------------------------------- did you see the strange thing? (i run ths command on a centos system) so if centos just rebuild the same src.rpm then do not need to modify the package and the spec! (ok this pacakge won't be included in centos anyway, just an example) since in that case the buildhost and vendor changed because of the build system and the summary and other part will change "automagically" even if the spec file contains _hard coded_ "Red Hat". this can save same useless work.. just my 2c. -- Levente "Si vis pacem para bellum!"
