chkconfig path
by Geert Batsleer 18 Feb '09

18 Feb '09

Hi all! I'm trying to install FOG (an opensource ghostlike backup/rollout server) on a centos 5 box but at the end of the isntaller script it can't find chckconfig altough it's in /sbn and I run the (redhat specific install) script as root. How can I make sure chckconfig gets found? Tried adding the full path in the script to /sbin/chckconfig but got the same error. Regards, Geert ------------------------------ ------------------------------------------------ * Checking package: perl...OK * Checking package: perl-Crypt-PasswdMD5...OK * Checking package: lftp...OK Configuring services. * Setting up fog user...Exists * Setting up and starting MySql../lib/redhat/functions.sh: line 440: chkconfig: command not found ...Failed!

I have the cluster running on a different vlan then my ISCSI traffic. Is that a problem? I would not like to put my cluster communication on the other vlan since thats iscsi dedicated now. I have now figured out that it isn't the restarting IP tables causing the trouble, but the issue is as follows: - Calling Group_tool dump This will cause groupd to run at 100% cpu. Dooing a strace on this process tells me its dooing some poll in an infinite loop: poll([{fd=1, events=POLLIN}, {fd=2, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN}, {fd=9, events=POLLIN}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN}, {fd=14, events=POLLIN}, {fd=18, events=POLLIN}, {fd=17, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN, revents=POLLNVAL}, {fd=-1}], 13, -1) = 1 - Calling Group_tool dump gfs This will cause gfs_controld to run at 100% cpu. Exactly the same as the groupd (strace): poll([{fd=2, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN}, {fd=11, events=POLLIN}, {fd=12, events=POLLIN, revents=POLLNVAL}, {fd=12, events=POLLIN, revents=POLLNVAL}], 8, -1) = 2 Sometimes my Mount will hang, but sometimes it will just continue normally. I can imagine this has to do with the amount of data going to the gfs Mount. So I guess it isn't really an iptables problem.. But im trying to debug that a little bit more as well.. Any clues? Thanks!! Sven

reading sar data
by muhammad panji 18 Feb '09

18 Feb '09

Hi, I have a problem reading sar data. I have some server but no monitoring tools like cacti or nagios on it. every end of month I got the sar log manually and have to generate report for it but I have no idea how to read it. on this page :http://pagesperso-orange.fr/sebastien.godard/tutorial.html i found there is tool called sadf, can i use it on CentOS 4 or it just available on Centos 5? I found sadf on centos5 but not on centos 4. are there any tools that could be used to generate a graphic from a month historical sar data? best regards, -- Muhammad Panji http://sumodirjo.wordpress.com

Avoid NTLM all together and use Kerberos between apache/squid, Active Directory and the Windows and Linux clients. Firefox and IE both support Kerberos authentication. I believe apache/ squid do too, but you need a manually create the service principal names in AD for those. Use pam_krb5 on the Linux clients to get a ticket on login. Use samba client on Linux hosts to join to domain and manage the Kerberos keytab file for the machine passwords. Use winbind to get passwd/group files via nsswitch. -Ross

Trying to restart IPv6 over PPP
by Robert Moskowitz 18 Feb '09

18 Feb '09

My IPv6 connection over my PPPoE link is down. IPv4 is up. I have tried: /etc/ppp/ipv6-up ppp0 and get the error: ./network-functions: line 78: ifcfg-: No such file or directory The gateway has been up and running for > 150 days. I have not been testing anything IPv6 out of my net for a while, so don't know when IPv6 connectivity went south. I don't want to restart the network, as I have a BIG rsync going right now (pulling down i386 FC10), and would like to get some external IPv6 testing done today....

vsftpd virtual users
by dnk 18 Feb '09

18 Feb '09

Good day all, I have followed the wiki article on setting up vsftpd on centos with virtual users. I was wondering if anyone had an example of knowledge on how to add another "readonly" user. I don't want to enable anon access. The issue I have is that the tutorial (from the wiki) uses the same real system user (ftp) - so permissions don't apply. d

This sounds like a possible solution, but I have no clue how to fix it. I googled already a lot on ip_conntrack + gfs, but don't see a possible solution coming up. Can someone/you please help me a little bit more with the issue? Thanks a lot! Sven
