Remote X: Linux to Linux
Plain Ol' Vanilla X11 Forwarding
NOTE: in the X11 world, the SERVER machine is the one listening for a connection (your desktop). The CLIENT machine is the one initiating the connection (the machine you are executing the commands on). I know, it sounds backwards but, it is actually correct if you understand the X11 connection.
1) Tell your X11 Server Linux box to accept X11 connections from the Client machines with the xhost command. You can add the the command to .bashrc or .profile:
EXAMPLE: xhost +192.168.1.36
2) Start the connection from the client (the remote) machine to the server (your desktop) machine: Connect to the remote machine via ssh/telnet/rlogin/whatever and run:
DISPLAY=X11_SERVER_IP:0;export DISPLAY;APPLICATION_YOU_WANT_TO_RUN & EXAMPLE: DISPLAY=192.168.1.10:0;export DISPLAY;xterm &
X11 Forwarding Over SSH
1) Edit /etc/ssh/sshd_conf on the remote machine.
CHANGE: #X11Forwarding no TO: X11Forwarding yes CHANGE: #X11UseLocalhost yes TO: X11UseLocalhost yes
2) ensure that X11Forwarding is enabled in /etc/ssh/ssh_conf on the local machine.
3) open an X11 forwarded ssh session to the remote machine:
ssh -X USER@REMOTE_MACHINE XAPPLICATION_YOU_WANT_TO_RUN
PROBLEMS
PROBLEM: ssh connection is complaining about an “Invalid MIT-MAGIC-COOKIE”.
FIX: start a less secure ssh session:
ssh -Y USER@REMOTE_MACHINE
