cr repo and firewalling
by Markus Falb 18 Jan '13

18 Jan '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I find myself in a complicated situation and would like to ask the oracle (choke!) for help. I would like to install the packages from the continuous release repo and the yum config for this repo says baseurl=http://mirror.centos.org/centos/$releasever/cr/$basearch/ well, I definitely do not want to allow worldwide outgoing http so I try to find the IPs # host mirror.centos.org mirror.centos.org has address 93.113.36.66 but! wait... # host mirror.centos.org mirror.centos.org has address 88.198.211.197 dns round robin is not very helpful for me doing firewall rules. How would you solve this yum and firewall thing? - -- Kind Regards, Markus Falb -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlD1wuEACgkQYoWFBIJE9eXs9wCghBGc/naF7c0ozZqJIw9huzXy fJQAn2NLrGTz9cy06dp/HIHFufWxgv9N =m2Of -----END PGP SIGNATURE-----

t-bird annoyance
by m.roth＠5-cent.us 18 Jan '13

18 Jan '13

Anyone got any clues? I'm running 6.3, t-bird 10.0.12, and KDE. I get emails with .docx attachment, and t-bird has no idea what to do with them (and doesn't even offer me a choice)."Change your preferences... So I open the source of the email, and at the beginning of the doc I see Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document; In system settings->advanced->file associations, I see the applications/vnd... is set for libreoffice. T-bird is still clueless. mark

5.9 logwatch yum filter broken
by Tilman Schmidt 18 Jan '13

18 Jan '13

After the upgrade to CentOS 5.9, all my CentOS 5 installations report only "Unmatched Entries" in the "yum" section of their daily logwatch mails. It seems the filter script /usr/share/logwatch/scripts/services/yum got broken: --------8<--------8<--------8<--------8<--------8<--------8<--------8< [root@dns01 ~]# /usr/sbin/logwatch --print --service yum --debug 5 [...] Processing Service: yum ( cat /var/cache/logwatch/logwatch.kKzXpf19/yum | /usr/bin/perl /usr/share/logwatch/scripts/services/yum) 2>&1 ################### Logwatch 7.3 (03/24/06) #################### Processing Initiated: Fri Jan 18 09:21:20 2013 Date Range Processed: yesterday ( 2013-Jan-17 ) Period is day.

And a minor nit: who came up with the silly idea of enforcing mode 600 for /var/log/yum.log in /etc/logrotate.d/yum? I don't think it increases security if the intern who checks the logs has to work with full root privileges all the time. -- Tilman Schmidt Phoenix Software GmbH Bonn, Germany

Hi, Does anyone know if "Red Hat Store" will be available in CentOS? Have a look here: http://www.redhat.com/products/storage-server/ I'm not referring to the "Red Hat Cluster Suite" which is already available. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Cell: 082 554 7532 Fax: 086 268 8492

You need to implement a remote task_setrlimit in your security module and call it directly from this functionWARNING: at security/security.c:51 security_ops_task_setrlimit() ?

autofs update brakes nested automount
by Theo Band 17 Jan '13

17 Jan '13

On my CentOS5 boxes the automounter fails after the last update to autofs.x86_64 1:5.0.1-0.rc2.177.el5 No update is seen on CentOS6 and things still work there. The home directory of users is setup using an auto.home map which is distributed using NIS: * fsutrecht02:/export/home/& /nobackup -noacl nasutrecht01:/nobackup/& /snapshot -ro fazant:/home_backup/ This maps a users home directory and and two subfolders ~/nobackup and ~/snapshot Now I see this in my logs: automount[6510]: parse_mount: parse(sun): can't find multi root thba I found that this still works: * fsutrecht02:/export/home/& The nested folders do no longer work. If the wildcard is removed, works: thba fsutrecht02:/export/home/& /nobackup -noacl nasutrecht01:/nobackup/& /snapshot -ro fazant:/home_backup/ Any idea how wildcards can be made to work (again) with nested mounts? Is it a bug? Thanks, Theo

5.9: wait, or CR?
by m.roth＠5-cent.us 17 Jan '13

17 Jan '13

Hey, folks, I just saw Johnny mention 5.9 yesterday, and this morning, my manager tells me he got about 100 emails from somewhere about 5.9 and a CR repo. So, my questions to the team is: is there a CR repo, and is there some urgency to enabling it, or shall we just wait for the release? The *only* thing I can think of having real issues with is the newest PIV cards.... mark

by Francisco J. Valero 17 Jan '13

17 Jan '13

Hi all. I need support about GFS2 and RHCS. Actually I have cman cluster formed by 9 nodes. All works whitout problems but when I try to include a new node in the cluster I must reboot all nodes because share partition GFS2 freezes. cman_tool status not show "Blocked activity" in each node and in logs all apears normally whitout any WARNING or ERROR in /var/log/cluster/* I have not found solution about this and I'm desperate. Any ideas? Thanks in advance -- Francisco J. Valero Departamento Técnico | Seguridad y Sistemas francisco.valero(a)masvoz.es Tel/Fax: 902500807 Ext. 106
