ldconfig issue?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Did others notic there seems to be a problem with ldconfig on Centos 5? It got apparant with the latest clamav update of rpmforge but it seems that ldconfig does not bild all the information that is required.

CentOS-Sparc - New 'Fedora Secondary' Discovery
by Worsham, Michael 01 Apr '09

01 Apr '09

This report/issue is geared to those attempting to find a CentOS/RH for Sparc. Currently, there is a slowdown to the development of CentOS for the Sparc platform. The current tftp64.img build for CentOS on Sparc does not have support for the low-cost Netra and Sunfire 1U servers, thus hinders any chance of this distro release being used for cheap hardware re-provisioning needs (i.e. basic web servers, database servers, etc). In the past, there was a project called Aurora Sparc Linux, which was based on the Fedora platform. There are older builds still available, but these are rather ancient in comparison to today's kernel and driver updates. Upon doing a bit of in-depth research, I did discover that Ubuntu did release a Sparc build under their v7.10 distro, which supports many older as well as new Sparc-based platforms including the low-cost Netra and Sunfire 1U servers. These special servers require the 'eri' driver commonly called the SunGEM driver. I did, however, stumble upon a 'Fedora Secondary' project which does have actual images and CD/DVD/NetBoot ISO builds available and is based on the Fedora 9 distro. http://archives.fedoraproject.org/pub/fedora-secondary/releases/test/9-B eta/Fedora/sparc/iso/ Upon initial testing, I found that the test ISO and the TFTP images do support the low-cost Netra and Sunfire 1U servers as well as other platform, but there seems to be an issue when it comes down to creating the actual disk environment. Out of five tries, three of them tried to create an 'ext2' disk build-out even when ext3 was specified. The remaining two would place the disks in a read-only status -- and even using a rescue boot CD -- failed to restore these to a read-write capability. I recommend to those looking at trying out a RedHat-based distro for Sparc, to look at this build. It might provide some guidance for the CentOS development team going forward for future platform releases. -- Michael

Fwd: Using probe dependencies for ordering

Hello crowd, I suggest the following: A new mailinglist, probably centos-devel-s390(a)centos.org and a separate IRC channel on freenode probably: #centos-devel-s390 And some wiki Space to appoint ppl and share knowledge. -- Mit freundlichen Grüßen, / with kind regards, Sascha Thomas Spreitzer http://spreitzer.name/

RPM of BrOffice.org
by Thiago Avelino 27 Mar '09

Morning staff, here in Brazil we can not be using OpenOffice.org because of trademarks and patents, I am sending the mirror of BrOffice.org that in the mirror of the CentOS-BR.org http://mirror.centos-br.org/broffice/stable/3.0.1/RPMS/ It would be very good for the people that download the CentOS here in Brazil the BrOffice.org already came installed. -- att.

RPM of BrOffice.org
by Claudio F Filho 26 Mar '09

26 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi My name is Claudio Filho and i was the L10N lead and yet am the marketing contact and native language to Brazil and pt-BR of OpenOffice.org project. Recently, Thiago told with me about the BrOffice.org(Broo) and i asked why haven't the Broo in CentOS. Today, he sent me informations about this list, i read all the thread, and now i will try to reply all questions about this thread. Just to make some things a little clearer. The name "Open Office" is trademarked in Brazil. The logo, splash and other branding elements are not. The trademark itself is registered in Brazil's Patent and Trademark Office[1] (INPI) and can be checked at their site. Unfortunately there is no direct link... [1]http://www.inpi.gov.br/ Because this problem, the owner of brand/trademark started a juridic campaign to get money of people that are using "OpenOffice*" in Brazil and requesting compensations($$) from developers like the brazilian OOo team and Sun Microsystems. They have *goods* lawyers, and we has luck of to get help with lawyers of Federal Gov for our defense. The result is that all user (win, mac or linux) that use a program 'OpenOffice*' (can be "Open Office", "OpenOffice" or "OpenOffice.org"), by interpretation of INPI, is breaking the copyrights of owner of the brand. So, by determination of Federal Government, is denied the use of "OpenOffice*", and the official option is BrOffice.org. To protect our devels and users, we created a NGO (with the same name) and registered the brand 'BrOffice.org' saving our necks (and of our users) of juridic problems. In 2006, i spoke with Rene Engelhard, lead of OOo team in Debian, about our problem and he created a "semi" meta-package[2] of Broo in him distro. Why "semi" meta-pkg? Because this pkg depends of OOo pkgs and have more the files and changes of name and images (splash, about, etc), with ~3.8Mb. [2]http://packages.debian.org/sid/broffice.org Today, for brazilian users that uses Debian haven't legal problems, and what Thiago (and me) wishes is extend this legal situation to brazilian users of CentOS. Ah! and the more important is that Broo NOT IS a fork of OOo. Broo is the pt-BR OOo! This question was discussed in the OOo Council and approved, and reflected in our page[3] inside of OOo Project.

SPARC Beta el5 SRPMS ?
by d b 25 Mar '09

25 Mar '09

To all... I know the Sparc EL5 port is beta/alpha/gamma... I was able to install base server package using a tftp image. ls -la /tftpboot/tftp64.img -rw-r--r-- 1 root root 9154949 Mar 24 16:39 /tftpboot/tftp64.img I even was able to download the recent curl-7.15.5-2.1.el5.4 update from redhat and rebuild it... (After installing alot of other rpms) . Using "sparc32 rpmbuild -ba specfile" worked like a champ.. Great job. The Sparc EL5 port works in my book. How can I get the SRPMS used to build the sparc el5 port?... It looks like a few have sparc specific changes/additions... For example... silo-1.4.13-8.c5sparc.src.rpm initscripts-8.45.17.EL-1.c5sparc.1.src.rpm There are others but I can only find a couple at http://sparc.centos.org/os/SRPMS/ Some of the rpms were recently rebuilt so someone is using t2000-c5 for fun....

An introduction and a s390 effort
by Sascha Thomas Spreitzer 23 Mar '09

23 Mar '09

Hello contributors and OSS friends, (Who am I?) My name is Sascha Thomas Spreitzer and I live in the eastern outback of Munich in Bavaria Germany. I am 23 years old and started with C and GNU Linux in the early age of 13. (What am I doing?) Most time I spend in the office fixing Unix dependant problems. Since now at Germanys biggest stock broker "Baader Bank". In future (starting first of April) ill design and realize AIX and z/Linux environments for the government insurance sector. If I'm not in the office, I go out with my girlfriend Lisa and we enjoy the little time we have together. I used to do traditional Shotokan Karate in JKA style. But stopped it a year ago, because I had no time left to do it. In holidays I try to gain progress with my software development skills. (Why centos and what I'm up to?) I had a chance to get a look at IBM's z/Series in the past and it arouse my interest. Some years passed and now I have to face z/Linux in my new position. >From the skills I gained in the past and the skills i'll gain in future, I want to contribute back to the community. Since a decade I'm using OSS and I deeply esteem the freedom. It's time for me to contribute. PS.: you can can IM me via IRC or Jabber: irc.freenode.net: sspreitzer Jabber: icefox(a)im.relinked.org -- Mit freundlichen Grüßen, / with kind regards, Sascha Thomas Spreitzer http://spreitzer.name/

Forum migration: newbb_to_phpbb
by Alain Reguera Delgado 23 Mar '09

23 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Guys, During the last few weeks I've been working on a migration script (newbb_to_phpbb) based on a code provided to me by Marcus Moeller to move Xoops+CBB forums, topics and posts into phpBB system. The users are copied from xoops user table onto an LDAP server. More information in the wiki page: http://wiki.centos.org/WebsiteVer2/forums/newbb_to_phpbb It would be nice if you could test this application, and check the overall process so we can get what we need to migrate newbb to phpbb. The application's download link is in the wiki page above. Note that it is in a test mode yet and requesting for comments.
