When I type
ssh gb-cs I mean
ssh gb-cs.cs.unc.edu but I couldn't get that to work consistently at home. I'd add it to the Search Domains section of the DNS tab in the Network Settings dialog but next time I hibernated or rebooted, it would be gone. This tip suggested adding a package and then making a simple change:
Using Synaptics Package Manager I got
sudo vi /etc/network/interfaces and I added
dns-search cs.unc.edu after the
iface line for the wireless interface.
This did not work for me. So I investigated the first proposed solution at the above page, but the file
head he refers to has a comment in it that says don't edit this file by hand so I decided that was a bad idea. The file tail in that same folder was empty and didn't say that, so I edited it and added
search cs.unc.edu. That seems to survive a reboot.
