by Carlos S 30 Aug '10

Howdy, Do we need to restart any service after making changed to pam modules? I have changed system-auth config, but not sure if I need to restart any service after making changes, e.g. ssh which uses pam. Any help? -- Thanks, CS.

kvm boot options
by Jerry Geis 30 Aug '10

30 Aug '10

I am trying to use -boot order=dc,once=d for kvm. It did not seem to work as it booted from CDROM (d) the second time around and was wanting to re-install centos again. 1st boot installs centos and auto reboots 2nd boot then begins OTHER things to do. Did I not have the command options correct above? Jerry

Freezing gnome terminals...
by John Doe 30 Aug '10

30 Aug '10

Hi, just wondering if you also experience gnome terminals freezing after a while...? It mainly happens over the week-end. I would leave a terminal open (with an ssh session to a remote site), come back on monday and type a few commands and it jwould just freeze. But it also happen from time to time randomly during the day (but still with days old terminals). Happens to my collegues too. The Gnome terminal Reset option would not do anything. any idea what could be the problem? Thx, JD

Strange Apache log entry
by Gilbert Sebenste 29 Aug '10

29 Aug '10

Hey everyone, Logwatch flagged something in my Apache logs, and it says it was a possible successful probe. Hmmm. Here's what it says: --------------------- httpd Begin ------------------------ A total of 1 sites probed the server 66.249.137.70 A total of 2 possible successful probes were detected (the following URLs contain strings that match one or more of a listing of strings that indicate a possible exploit): 66.249.137.70 - - [21/Aug/2010:04:56:56 -0500] "GET /mystuff/?g=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP/1.1" 200 5231 "-" "libwww-perl/5.810" 66.249.137.70 - - [21/Aug/2010:04:56:56 -0500] "GET /?g=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP/1.1" 200 14169 "-" "libwww-perl/5.810" I didn't see anything on my server this morning, as I checked around it. Is this something to be concerned about? I'm fully patched (yum updated through this past week). Anybody else see this? ******************************************************************************* Gilbert Sebenste ******** (My opinions only!) ****** *******************************************************************************

Ignorant question on pam_shield
by Timothy Murphy 29 Aug '10

29 Aug '10

I've seen pam_shield recommended several times for protecting against malicious login attempts; but I'm not quite clear if this requires one to be already running some pam-based software? Also, I'm running shorewall, and would prefer a shorewall based protection, but the advice I read on googling for this seemed excessively complicated. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Slow domain resolution problem
by Gabriel Tabares 28 Aug '10

28 Aug '10

Hi everyone, I've just joine the list as I am having an issue with our CentOS servers. The domain resolution is extremely slow from the application but doing an nslookup gives an immediate response. All the applications have the same issue, as do all the servers. I have been looking for the solution all over the web and all I have found are references to disabling ipv6. - By setting enable_ipv6 = no in /etc/sysconfig/network, which is already done on all the machines. - By blacklisting the ip6 module, which is not an option as it is used by the bonding module. Just for the sake of it, I tried it and, as expected, the bonding module did not come back up. If bad comes to worse, I could set up host entries for the main machines in /etc/hosts, but I really am trying to avoid that. Any suggestions? Thanks Gabriel Tabares
