Someone on the Dell mailing list was kind enough to point that although OMSA (OpenManage) on Ubuntu is not supported by Dell, the SARA institute in the Netherlands has a couple of OMSA Debian packages for Ubuntu ready for use. Check their site!
Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.
