Dell recently published a little more details about what Ubuntu Certified and Ubuntu Ready means. Even though Dell does not officially support Ubuntu, their hardware is labelled as Certified by Canonical and they can also provide with paid support for Enterprises that require it.
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.
