Alan,

OK.

>Machine in question is ...

Thanks.  I logged onto the machine both as 'mcidas' and as a student
and three things that contributed to problems:

o there were three files in the student's mcidas/data directory that should
  not be there: FRAMED.001, TERMCHAR.001, and GRAPHICS.  These fiels
  are created on a per-session basis and kept in a subdirectory of the
  users .mctmp directory.  I removed them in a cleanup effort.

o there are REDIRECTions for ASUS1* and FSUS2* in the user's
  mcidas/data/LWPATH.NAM pointing to /var/data/ldm/surface/front.  Since
  there is no such directpory, I removed the REDIRECTions.  You may want
  to edit the LOCAL.NAM copy of EXAMPLE.NAM in the ~mcidas/data directory
  and remove these REDIRECTions there (so new users will not run into
  the same problem).

o I found a bug in ~mcidas/bin/upcguiprocs.tcl that was causing plots/contours
  to be put on the current frame instead of on the frame specified by
  the various McIDAS strings (e.g., ?SFRM, ?UFRM, ?NFRM, ?PFRM).  I
  am simply amazed that I never ran into this problem before.  I guess
  that it just goes to show that I always overlay analyses on top of
  satellite images.  

So, the copy of upcguiprocs on 199.17.31.16 in the ~mcidas/bin directory
has the fix for the problem you have been seeing.  You should propogate
this module to your other machines running McIDAS-X.

The problem is not related to the LDM in any way.

I am betting that telnet services were shut off in /etc/inetd.conf.  Edit
this file as 'root' and make sure that the telnet line is not commented
out:

telnet  stream  tcp nowait  root    /usr/sbin/tcpd  in.telnetd

If it is, uncomment it and then send a HUP signal to the inetd process:

kill -HUP <process_id_of_inetd>

You would do the above IF you want to allow logins from other machines,
of course.
