[daip] tape error (aips)

[Pedro Manuel Augusto]

Dear Eric and colleagues,

I have changed permissions and now wny user inside the group can work with
aips perfectly. I also have TV, etc. Now the true tests come: I am trying
to load image data from a tape and check tv interactive, etc.

However, I find the problem right at the start with the Tape reader. I am
using a PC_Linux in my office connected to our local net and external
world (where I have AIPS installed). THe tape drive is also connected to
the local net and the world via a Solaris workstation. I can telnet
overthere and play with other tapes remotely (of course, after telneting
'remotely' has a different meaning):

[augusto at augusto augusto]$ telnet astro
Trying 193.136.232.8...
Connected to astro.uma.pt (193.136.232.8).

Now from aips here:

I have tried all logical possibilities and still cannot get a conversation
with the tape reader. Is there any port that must be opened in the
workstation for this purpose (apart from telnet and ftp ports)?

Thanks for your help.

Pedro
