Xen guest not starting automatically
by Jussi Hirvi 30 Oct '10

30 Oct '10

I have a xen system with four guest OS's, (see list below). When I reboot the host, other guests autostart normally, but mail2 does not. I have found no explanation for this. The host and all guests are CentOS 5.5.

RPM DB DSA Signature Errors
by Camron W. Fox 30 Oct '10

30 Oct '10

Alle, I'm running CentOS 4.8. I just started seeing these errors during RPM operations: error: rpmdbAdd: skipping h# 990 Header V3 DSA signature: BAD, key ID 443e1821 error: rpmdbNextIterator: skipping h# 969 Header V3 DSA signature: BAD, key ID 443e1821 I've cleared out the __db.* files and tried to rebuild the DB with no luck. I've also tried this: http://forums.fedoraforum.org/showthread.php?t=145858 and this: cd /var/lib tar zcvf /var/preserve/rpmdb-`date +"%d%m%Y"`.tar.gz rpm cd /var/lib/rpm ls -l rm -f __db* /usr/lib/rpm/rpmdb_verify Packages rpm -qa 1> /dev/null rpm -v --rebuilddb with no joy (also with the PubKeys). Any ideas as to what to try next would be *most* appreciated. Best Regards, Camron -- Camron W. Fox Hilo Office High Performance Computing Group Fujitsu Management Services of America, Inc.

I have been trying to get to the CentOS LiveCD site at projects.centos.org the last couple of days, but have been unable to reach it. Is it down, and is there any info on when it might be back up? Thanks, -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

selinux with samba
by Geert Batsleer 29 Oct '10

29 Oct '10

I'm having problems setting up a samba server with sellinux in centos 5.6 (x64). My samba config works flawlessly when selinux is disabled but fails to access shares when selinux is enabled. Wich command makes it possible to run samba with selinux without disabling it, now I've done: "set sebool -P smbd_disable_trans 1" but doesn't really solve my problem. Thanks in advance! geert

How to access one machine behind iptables, on different subnet?
by Rudi Ahlers 29 Oct '10

29 Oct '10

Hi all, I wonder if someone can help me with this: The setup is as follows: 192.168.1.254 - wireless ADSL modem, with DHCP pool on 192.168.100 - 192.168.200 192.168.1.250 - Linux firewall RED interface 192.168.2.250 - Linux firewall GREEN interface. There are some normal LAN clients behind the Linux firewall's GREEN interface, which can all access each other's shared services and also all the clients behind the RED interface. i.e. those clients connected to the 192.168.1.254 ADSL wifi APP directly. Now I want the clients on the "outside" to connect to one specific host on the inside, behind the GREEN interface, on IP 192.168.1.20. How would I do that? I know I can do this with port fowarding, but need many ports forwarded. How do I give full access to all ports on this IP, instead of forwarding every port? Does that make sense? Currently no clients on the 192.168.1.0 subnect can access any client on the 192.168.2.0 subnet.

faster fsck ?
by przemolicc＠poczta.fm 29 Oct '10

29 Oct '10

Hi, we have CentOS ftp server (vsftpd) which has a lot of users who are writing and reading a lot of small files from/into its own accounts (and other servers - using samba client - are reading these files and putting them into outside database). Since this server is under heavy load its availability is important. >From time to time we "crash" this server (don't ask why ...) but then fsck is running for over 20-30 minuts. The question is: is there any other _stable_ filesystem (xfs ?, jfs ?) which we can use instead of ext3 which is (quite) immune to crashes and whose fsck is "faster" (by design) then in ext3 ?

29 Oct '10

heads up and fyi folks... CentOS 4 latest... SpamAssassin version 3.3.1 running on Perl version 5.8.8 :-) i noticed on a centos 4 box after doing a manual yum update and getting 2 updated perl packages from rpmforge again, just a heads up as rpmforge has been rock solid for us for years so we are no bashing spamassassin would not restart after the updates.... spamd: Oct 27 22:32:01.340 [27493] warn: netset: cannot include 127.0.0.1/32 as it has already been included spamd: Oct 27 22:32:01.340 [27493] error: spamd: aborting due to add_cidr error spamd: spamd: aborting due to add_cidr error spamassassin: spamd startup failed of course, there was no such network include in the local.cf file as it is default... the fix for me was to # grep perl-NetAddr-IP /var/log/yum.log Jul 29 23:40:44 Updated: perl-NetAddr-IP.i386 4.027-1.el4.rf Sep 30 18:29:27 Updated: perl-NetAddr-IP.i386 4.032-1.el4.rf Oct 03 10:00:09 Updated: perl-NetAddr-IP.i386 4.033-1.el4.rf Oct 27 21:46:26 Updated: perl-NetAddr-IP.i386 4.034-1.el4.rf Oct 27 22:44:47 Installed: perl-NetAddr-IP.i386 4.033-1.el4.rf wget http://packages.sw.be/perl-NetAddr-IP/perl-NetAddr-IP-4.033-1.el4.rf.i386.rp m rpm -e --nodeps perl-NetAddr-IP yum localinstall perl-NetAddr-IP-4.033-1.el4.rf.i386.rpm service spamassassin restart again, just a heads up... - rh
