Dunno about your system, or TELNET, but a `who` gives:

matt                 ttyp3       Jul  4 09:14   (thomas:0.0)
henry                display     Jul  4 07:37

The (thomas:0.0) says that I'm rlogin'd from thomas. On my 'own' system,
it doesn't list me coz of xdm not updating the /etc/utmp file (rickin' nickin'
rackin' %$%!$%). Use `tty` to work out which line in `who` "you" are (if any),
then see if `who` tells you the host or display name & extract it for setting
DISPLAY (this doesn't work perfectly for rlogins from the second or subsequent
screens, though this setup is not common?). Use ":0" if no host given.
    I leave the shell script for this to the reader. :-)
