This is just a self-reminder.

ssh -t -L 8000:localhost:8000 lec.cs.arizona.edu 'ssh -L 8000:sebeos:80 robotlab@sebeos'

lec.cs.arizona.edu is in the DMZ, and sebeos.cs.arizona.edu is one of the machines in the robot lab, which is behind the firewall. So, I’m basically double tunneling to sebeos via lec to access to sebeos from outside the firewall.
