don't worry about this because telnet of a session does this automatically for
you.
see man page.
" environ arguments...
The environ command is used to propagate environment variables
across the telnet link using the TELNET ENVIRON protocol op-
tion. All variables exported from the shell are defined, but
only the DISPLAY and PRINTER variables are marked to be sent
by default. The USER variable is marked to be sent if the -a
or -l command-line options were used."

setenv DISPLAY

try and see ~/.profile file for initialization script for shell.
echo(ing) localhost and localdomain what are the valuse of them or
echo localhost.localdomain
or do
echo $DISPLAY
as this should correspond to your ip address from where you are telnetting.
