On my Fedora Core 1 box, I don't think I need the -X: it's
assumed by default. This is the same on all Red Hat, I think.
You can also do it all on one line.
local$ ssh (-X) remotebox name-of-app
which will prompt for your password on remotebox and then
just run the application. This applies both to command line
applications (ssh remotebox date) and to GUI ones.
I notice you say "connect with telnet". It is possible
that sshd is not running on the box you want to connect
to with ssh, which of course will stop this working.
