In order to get that to work, you'd have to have a login on one of CAEDM's samba
servers, and be able to ssh out from there.  On top of that, I believe
that BYU's routers block traffic on ports 137-139 and 445; at least they
did in the past.

Theoretically, if he were able to SSH into one of the externally
accessible CAEDM machines, then he could set up SSH port forwarding to
eventually get to the machine.  However, he wouldn't be able to set up
a port-forwarding connection using ports 137-139 (because they're
privileged ports), and most CIFS file-sharing systems don't like running
on alternate ports.  smbclient can, I think, but Windows becomes very
unhappy.

Oh yeah, then there's the issue of SSH not being able to tunnel UDP
traffic.  There goes your netbios name resolution, which also makes
Windows very unhappy.

Trust me, if you want CAEDM files from off-campus, sftp/scp or citrix are
about the only ways to get them.
