forums + portal for {lang}.centos.org sites

Hi, Earlier in the evening today Ralph, Fabian and I had a chat about the present state of the language subsites. This email sort of summarises the main issue ( s/w ). We seem to have run into a slight technical hitch with punbb/fluxbb. They dont support LDAP as a backend. And we had decided a few months back that all new rollouts must have ldap backend so we can rollin CentOS-DS / openldap based backend. So we need to look at alternatives, and since the primary focus of these international sites is going be forums : Here is a shortlist ( if there is anything else that people are aware of, please add to this list ) - phpBB - SMF - Fudforum - phorum - fluxbb Requirements: - Must be able to scale ( couple of hundred thousand msgs ) - Must be able to handle ldap auth ( if it cant, whats involved in writing the ldap-auth portion ) - Must address the specific requirements raised by the present www.centos.org forum users ( Can you please fill this section in ? ) - Must support all languages we need ( pure utf8 support would be good ) - Secure - Skin'able Nice to have: - Capable of running multiple instances from a single deployment - responsive community :D Things we will need to do: - Decide on what s/w to use. - Give the ArtWork people enough time to get the look & feel sorted. - Migrate newbb forums from www.centos.org to $system ( hey, english is a language too :D ). - Migrate fr.centos.org into the final s/w - setup {de/es/ja/it/pt_br}.centos.org Actions: Ralph and Fabian are going to work on setting up a test ldap server, once that is online we will then start by installing into our test-vm-farm the various s/w to eval them. If anyone would like to help, please feel free to jump right in. I'll setup a wiki page for this issue, which might be a good place to track progress. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq

yum-3.2.8 for Centos 4 backport, part II.
by David Hrbáč 30 Jan '10

30 Jan '10

Hi, I have again worked on yum 3.2.8 for Centos 4 today, after a long time. The result is backported package yum-3.2.8-9.el4.hrb.2.1.5 which is the upgrade of yum-3.2.8-9.el4.hrb.2.1.3 I've been using smoothly for quite a long time. Packages are in testing repos: http://fs12.vsb.cz/hrb33/el4/hrb/testing/i386/repodata/ http://fs12.vsb.cz/hrb33/el4/hrb/testing/x86_64/repodata/ I'd like to ask for QA tests. This patched version passes all the internal yum tests (aka 'make test'). Regards, David Hrbáč

5.4 install failure
by John Summerfield 30 Oct '09

30 Oct '09

I've mirrored the 5.4 repos and run createrepo on WBEL crossed with Centos4 on account of the WB folk seem to be MIA. Presumably, there's something wrong with my incantation of createrepo or something, because anaconda complains. It says my repo is butchers and proffers a reboot button. "Unable to read group information from repositories, This is a problem with the generation of your install tree." Okay, above is background. Here's the odd bit. I choose the one button on offer, and Anaconda goes on and installs! I'm not sure what it installs, but there is a bootable system, A kernel, grub are both properly in place. I can login as root, but root's dot files are not in place, so that bash doesn't do its initialisation. Manually copying the contents /etc/skel works. Can't really see what's installed because rpm isn't. It's really secure, it starts no daemons at all. Of course, anaconda should be rebooting, but this is way more entertaining. Am I right to think I should be telling createrepo about the file, comps.xml? -- Cheers John -- spambait 1aaaaaaa(a)coco.merseine.nu Z1aaaaaaa(a)coco.merseine.nu -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 You cannot reply off-list:-)

VirtualBox + CentOS 5.3/5.4 (xrandr issue?)
by IT2 Stuart Blake Tener, USNR 29 Oct '09

29 Oct '09

ALCON, I recently tested CentOS 5.3/5.4 with VirtualBox, and had some issues getting the video to pronounce itself properly. After logging on it was able to function in full screen mode capably (when I had used a customized xconf.org file that someone had published as "working", as well as having installed the VirtualBox "guest additions"), but the login screen did not configure into a proper manner. I read a few postings about this issue being related to the xrandr library version that is used within CentOS, but since I do not have RedHat 5.3 or 5.4, presume this might be a CentOS only issue for some reason? Can anyone enlighten me regarding this issue and any recommended methods for working around it? Thanks in advance, and do have a most wonderful and blessed day. -- IT2 Stuart Blake Tener, USNR, N3GWG (Extra), MROP Beverly Hills, CA / Las Vegas, NV / Philadelphia, PA / Washington, DC mobile: (310) 358-0202 Nextel: 124*233172*14 (direct connect) e-mail: teners(a)bh90210.net

What help do you need on getting persistence working, or on LiveCD development in general? All, Is there interest in a LiveDVD with more functionality than will fit on a CD? Perhaps "full desktop/office/productivity/multimedia" GNOME and/or KDE versions? How about LiveCDplus (or LiveDVDplus) as discussed in earlier threads? Perhaps add drivers and/or firmware for common Wifi cards from RPMforge and/or ELRepo? Multimedia add-ons? Obviously there may be licensing or other issues depending on what is added. One possibility could be finding another site to host the images - as in Omega for Fedora. http://www.linux-mag.com/cache/7450/1.html Should the LiveCD tools be in a centos.org repo? Speaking of the tools - a bit OT... In my testing while writing http://wiki.centos.org/HowTos/InstallFromUSBkey I found the centos syslinux not to work (could not find the kernel when booting from USB), while the livecd version did. Comments or insight on this issue would be appreciated. Could not find any bug reports in either the CentOS bug tracker or upstream on the problem. Phil

Mock patch speeds up 'mock init' to 5 Seconds from cache (linked, rsync'd)
by Brian Schueler 28 Oct '09

28 Oct '09

Hi all, i've made a patch that extends mock-helper for the two new internal commands 'save' and 'restore' for use with the new added script /usr/libexec/mock-cache-copy that generates a root cache, which is linked against the root tree and which is copied statically. This takes the double harddisk space of the root tree (buildsys-build install) but hard disks are big enough today. The advantage of this is that the files in the cache are hard-linked to the files in the mock root tree that makes it extremely fast to delete files (mock clean phase) and to relink them (copy -ax ... on mock init phase) while unpacking the cache. The static copy is used to repair touched and modified (linked) files with rsync. With this new option 'mock init' takes only 5 Seconds (between Enter press and shell prompt). The source package (with the patch included) can be found on the Beuth repo at: http://141.64.26.2/repo/bs/el5/SRPMS/mock-0.6.13-5.bs.el5.src.rpm Especially my old PowerBook G4 / 400 MHz PowerPC (running C-5 ppc edition) benefits of this feature (keeps the CPU away from tar and gzip and uses the slow harddisk efficiently). I hope this useful patch find a way to upstream (Fedora). Please give me feedback and comparing benchmarks (against mock's standard cache). ( The global config /etc/mock/defaults.cfg is set up for using the additional caching method). cheers, B.S.

lightweight LiveCD installer for CentOS-5.4 available - zyx-liveinstaller
by Douglas McClendon 27 Oct '09

27 Oct '09

I thought some of you might like to know- The latest version of zyx-liveinstaller (0.1.15) now supports the CentOS-5.4 LiveCD/USB. http://filteredperception.org/smiley/projects/zyx-liveinstaller/ This is a ~100kb rpm that can be installed in a running LiveCD/USB session. Once run, zyx-liveinstaller will then allow you to install the running system permanently to system-disk. This is like the anaconda/liveinst installer available with the Fedora LiveCD/USB, except- a) it works _rebootlessly_! After installation completes, you simply eject the LiveCD or remove the LiveUSB and continue using the now installed system. b) it is still relatively immature, but gets the job done (as far as I've tested). Installation to external usb drives also works. c) it can easily be included in a custom CentOS LiveCD spin, without the downside of having to have an unsupported version of anaconda on the system. d) it is a fairly simple pygtk frontend for a bash backend. In fact, all you really need is the single bash script /usr/sbin/zyx-liveinstaller-cli. NOTE: that like the Fedora LiveCD installer, it is a *destructive* install. Target partitions/volumes get reformatted. ----------------- To do a commandline installation with no seperate /boot partition, the rootfs on /dev/sda2, and the swap partition on /dev/sda3, you would just run- rpm -Uvh \ http://filteredperception.org/downloads/zyx-liveinstaller/zyx-liveinstaller… zyx-liveinstaller-cli \ /dev/sda2 /dev/sda2 /dev/sda3 ----------------- Note, that if you throw a copy of the 100kb rpm inside the LiveUSB version of CentOS-5.4, you have a totally portable offline installable version of CentOS. This is definitely not as seriously usable as the traditional DVD installer on bootable USB form, but might have its uses. Bugs, comments, criticisms, and feedback are encouraged. Now that I've got this working, I'll really get to work helping Patrice crossport my old LiveUSB persistence patches to Fedora-8/9 to CentOS-5.*. peace... -dmc P.S. To get CentOS-5.4 LiveUSB to boot on my acer aspire one, I had to change the syslinux.cfg line of 'vesamenu.c32' to 'menu.c32' (and copy menu.c32). Otherwise an unusable and very grey syslinux bootloader. Hopefully just a problem with this netbook.

Re: [CentOS-devel] [CentOS] EDAC Kernel Panic 2.6.9-78 and above
by Chris Miller 26 Oct '09

26 Oct '09

Apologies if this is not the correct place to post this issue. I've gotten some feedback on the user's list, but it seems that getting some developer insight may be appropriate before opening a bug report. Please see the original thread here : http://lists.centos.org/pipermail/centos/2009-October/084011.html memtest86+ found no issues on 8 passes. Since this server has been solid for a couple of years, I'm inclined to think this is a bug, or EDAC is finding an issue in some other subsystem (not memory), but the error info is not sufficient to determine what is really going on. I have a few Super Micro servers (various motherboards and revisions) with this chipset running various kernels and versions of CentOS (with/without i5000_edac). That said, I think I'm in a position to provide some helpful information to approach this issue, I just need to know where to go with it. I'm happy to build a custom kernel with additional code to diagnose the issue. If needed in the short term, can I simply unload i5000_edac without crashing the server. Thoughts? Chris

QA accessibility
by Phil Schaffner 18 Oct '09

18 Oct '09

A message on centos-users has raised a question in my mind about the openness of the QA process. I'm pretty sure that there is no desire to greatly expand the QA team, but on the other hand a few more serious QA testers might be worthwhile. I started to reply to the message below with a link to an announcement of opportunity to join the QA team from the centos-devel list, and possibly to add a bit to the "Contribute" page, but decided it might be better to bounce the idea around here instead. Announcement on CentOS-devel: http://lists.centos.org/pipermail/centos-devel/2007-February/001200.html > [CentOS-devel] CentOS 5 Beta Initial Test Release > Lance Davis lance at uklinux.net > Wed Feb 21 13:14:16 UTC 2007 > > We are about to release an initial internal test release of CentOS 5 beta > to our qa team. > > If folks here want to be a part of that test they need to join the > centos-qa list (http://lists.centos.org/mailman/listinfo/centos-qa) and > send a message to this list (centos-devel) saying that > they would like to be a part of the qa process and join the qa team, > with details of relevant experience if you are not known to the core > developers. > > Membership of the centos-qa list will then be approved. > > > Lance > > -- > uklinux.net - > The ISP of choice for the discerning Linux user. http://wiki.centos.org/Contribute#head-1c14314cdaa251daca6c3a79ff7510c5c05d… Proposed addition to Contribute: "Testing of new releases is done by the CentOS Quality Assurance (QA) team. People interested in helping with QA should first join the [http://lists.centos.org/mailman/listinfo/centos-devel CentOS Developer's list] and [http://lists.centos.org/mailman/listinfo/centos-qa CentOS QA list] and send a message to mailto:CentOS-devel@centos.org, with details of relevant experience if not already known to the core developers, saying that they would like to join the QA team." I notice that the QA list is not on the CentOS list of lists. Not sure if this is by design, or has just been overlooked. http://lists.centos.org/mailman/listinfo Phil -------- Original Message -------- Subject: [CentOS] Centos 5.4 'prerelease-access' - is there such a thing?

Of course, this kind of use is depending on the way the new upstream RHEL sources are processed, so maybe there won't be a complete set of packages at all until maybe one or two weeks before the release.
