I have 2 redhat machines and they are redhat 5 and redhat 4. I setup rlogin for both machines so can rlogin from either of machines to the other. Let's call redhat 5 is pc5 and redhat 4 is pc4.
So far rlogin works for me. When i'm in pc5 and want to connect to pc4 by use this command below:
rlogin -l username 192.168.1.4
after i got log in, I can't open a graphic application from terminal line which I can do it when i was in pc4.
The error message is : Gtk-WARNING **: cannot open display.
The purpose is I want to run graphic application A in pc4 when i am in pc5 instead of log in pc4 then run it. Any idea ? Thanks
