   The only problem is, I haven't figured out a good way to get DISPLAY
   set correctly using the rlogin method.

You need my xdsp script, and the code in my .login file:


BTW, the fact that the .login code checks for both xt?. and xt. has some
history; it isn't terribly important now.

xdsp (note that this requires a variable XDISPLAY that contains your
"real" DISPLAY variable, since it's usually unix:?.? on your local
machine.  It relies upon the fact that TERM is passed across rlogin and
rsh.  A similar hack works for some versions of telnet.):

#!/bin/sh
TERM=xtu.$XDISPLAY
export TERM
exec rsh $*

Put this in your .login:

# This hair unpacks the TERM variable into DISPLAY
if (($TERM =~ xt?.*) || ($TERM =~ xt.*)) then
  setenv DISPLAY `echo $TERM | sed 's/xt[^.]*\.//'`
  setenv XDISPLAY $DISPLAY
  echo $DISPLAY | egrep '.*:[0-9]\.[0-9]$' >& /dev/null
  set term = xterm
  setenv TERM xterm
endif
