Remote shell and IDL, [message #15225]

I'd like to run IDL remotely in a unix environment doing something
like...

rsh remotehost "export DISPLAY=localhost:0 ; idl"

from localhost.

This works, but unfortunately the 'IDL> '-prompt doesn't pass through
to localhost, which confuses my emacs shell (idl-shell.el).

Any suggestions? Thanks, Lars

hi lars

i don't know a solution with rsh for your problem
> rsh remotehost "export DISPLAY=localhost:0 ; idl"

but:
1) the problem is that rsh does no allocation of a tty.

2) with secure login it's no problem:
ssh -t remotehost idl (ssh set your display automatically)

so convince your sysmanagers to install ssh (version 1 not 2, the
version 2 is very buggy) ...

3) other possibility:
run your idl-program on the remotehost via a file:

make a file myprog.test:
cat > myprog.test <<EOF
print,"hello"
xloadct
wait,3
exit
EOF

then run idl by typing
rsh remotehost "export DISPLAY=localhost:0 ; idl myprog.test"

i hope this helps you a little bit

Hi Lars!

You might be able to have the DISPLAY env variable set appropriately
by using the following, which assumes you are using TCSH shell, which
has the $REMOTEHOST variable:

if ( $?prompt ) then
setenv DISPLAY local-host:0.0
if ( $?REMOTEHOST == 1 ) then
test $?REMOTEHOST && setenv DISPLAY ${REMOTEHOST}:0.0 >&
/dev/null
endif
endif

I put this in a global startup file that gets sourced by everyone's
.cshrc file.
