mutt execution by daemon
by Joseph L. Casale 06 Jan '10

06 Jan '10

I have a user w/o a shell that runs an app as a daemon that needs to use mutt to email an attachment from a script. During testing when the app was ran as root everything worked:) Now that we obviously are running as a user w/o a shell this little bit broke. I used mutt as I needed to send the attachment as mime, and the ability to specify a muttrc from the cli when executed was useful so we could tweak the mail headers etc... Since there is no local mb's at all on this server, are there any mutt gurus that know off hand how I can manipulate the behavior of mutt to simply send w/o looking for a mailbox? Thanks, jlc

Software RAID1 Disk I/O
by Matt 06 Jan '10

06 Jan '10

I just installed CentOS 5.4 64 bit release on a 1.9ghz CPU with 8gB of RAM. It has 2 Western Digital 1.5TB SATA2 drives in RAID1. [root@server ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/md2 1.4T 1.4G 1.3T 1% / /dev/md0 99M 19M 76M 20% /boot tmpfs 4.0G 0 4.0G 0% /dev/shm [root@server ~]# Its barebones right now. Nothing really running. I intended to move our current email server over to it eventually. The thing is slow as mud due to disk I/O though. I have no idea whats going on. Here is a bit of iostat -x output.

rsyslog v3 RPM for CentOS/RHEL
by Dan Burkland 05 Jan '10

05 Jan '10

Hello all, I have been doing some research on integrating rsyslog with GSSAPI authentication. I have discovered that the current version of rsyslog available in the repository does not support GSSAPI. I am wondering if any of you bright individuals out there have been discovered an rsyslog v3 RPM. If worse comes to worse I can always make my own RPM however this would greatly save me some time. Thanks all, Dan Burkland

conga and "virsh nodeinfo"
by Dirk H. Schulz 05 Jan '10

05 Jan '10

Hi folks, I have run into a confusing problem. My initial problem is: Conga does not offer "Add a virtual machine service". So I googled and found a RedHat advisory on that: http://rhn.redhat.com/errata/RHBA-2009-1623.html which points updates that should fix this. I checked on my cluster, but the relevant packages are current (and even if ALL packages are current it does not work). So I tried manually what is described in the above advisory: "virsh nodeinfo --readonly" throws an error saying that "--readonly" is not implemented. That seems to be the problem. Running "virh nodeinfo" as a non-root user (like Conga does) leads to an error as described in the above advisory. Reading the man page on virsh suggests that there is a --readonly flag to URIs, not to simple virsh commands. Now I am stuck. Googleing does not lead to anything helpful. Has anyone else run into this and resolved it? Or can someone send me a valid vm ressource entry for the /etc/cluster/cluster.conf file so I can adapt that? I have not found really enlightening examples on the web, and docs on this seem quite sparse. Thanks for any hint or help. Dirk

Centos 5.4 and TYAN s4985 motherboard....
by Tom Bishop 05 Jan '10

05 Jan '10

Was wondering if anyone has any luck with the Tyan s4985 motherboard, I had loaded up the latest 5.4 release and in installed most everything that I wanted but when I loaded it up, as in processor wise it would lock up. Funny thing I could still ssh to it but not do a su - or anything from the console. I think it is kernel related and tried the previous kernel but it still exhibited the same symptom. The only thing I saw in the log was a message about a soft lockup on cpu0, there is a open bug for that but from the description doesn't appear to cause any issues. I am running 4 opteron 8356 just for clarification....

IPTABLEs and port scanning
by James B. Byrne 05 Jan '10

05 Jan '10

I see many entries in /var/log/secure similar to these: . . . /var/log/secure.1:Dec 31 08:00:55 gway01 sshd[7220]: Received disconnect from 93.89.144.31: 11: Bye Bye /var/log/secure.1:Dec 31 08:00:58 gway01 sshd[7221]: Failed password for root from 93.89.144.31 port 60100 ssh2 /var/log/secure.1:Dec 31 08:00:58 gway01 sshd[7222]: Received disconnect from 93.89.144.31: 11: Bye Bye /var/log/secure.1:Dec 31 08:01:02 gway01 sshd[7223]: Failed password for root from 93.89.144.31 port 60962 ssh2 /var/log/secure.1:Dec 31 08:01:02 gway01 sshd[7224]: Received disconnect from 93.89.144.31: 11: Bye Bye /var/log/secure.1:Dec 31 08:01:05 gway01 sshd[7227]: Failed password for root from 93.89.144.31 port 33612 ssh2 /var/log/secure.1:Dec 31 08:01:05 gway01 sshd[7228]: Received disconnect from 93.89.144.31: 11: Bye Bye /var/log/secure.1:Dec 31 08:01:09 gway01 sshd[7229]: Failed password for root from 93.89.144.31 port 34504 ssh2 . . . As you can see, the ports are not those associated with the service requested. SSHD is configured to listen on the standard port (22) and only on a single IP address that is supposed to be reachable only from the internal network (this is a multi-homed system configured as a gateway). These are getting through the brute force filters because the attempts are directed against unchecked ports. I suspect that these represent no immediate danger to our systems because there are no active services on any of the ports and because we have a guillotine rule at the end of our INPUT chain. The firewall is configured to only allow connections to specified ports and to drop any new connection attempts to all the others. My confusion is over why these things are making it into the logs at all when sshd does not listen on those ports and the ports themselves are supposed to inaccessible through the firewall. There presence inoculates a doubt in my mind that things are properly configured. I would appreciate any insight as to why these attempts are nonetheless logged by sshd. -- *** E-Mail is NOT a SECURE channel *** James B.
