[daip] Fwd: Remote use of AIPS

[Jared Crossley]

Okay, the TV is working now.  Thank you all!

I removed the .rhosts file, and created the ~/.ssh/config file as 
Patrick suggested.  I then started aips with "aips 
tv=jhc.aoc-vis.nrao.edu tvok", and the local TV works.

Ultimately, I want to be able to run AIPS remotely from home.  Will 
this same method work outside the building?  I have been told that 
imager-b is behind a firewall, so I am planning to ssh first to hamal, 
for instance, and then to imager-b.

Patrick, I'm not sure what you mean by "the resolv.conf issue".  Is 
this a concern?
