[daip] Fwd: Remote use of AIPS

[Jared Crossley]

I sent the following AIPS question to Eric Greisen, but Lorant 
suggested I send it to daip instead.

My latest attempt, as suggested by Lorant, is described at the bottom.

After talking to Lorant, I have setup ssh on my laptop to allow 
no-password logins from jcrossle at imager-b to jared at jhc.aoc-vis.nrao.edu 
.  However, when I start AIPS on imager-b, I get the same error 
messages about the TV.
