Handle ssh X11 forwarding in .bashrc
Authored by: emarmite on Sep 27, '05 01:30:22PM
Er, have I misunderstood this hint? To enable X11 forwarding, simply use the -X flag in ssh:

-X Enables X11 forwarding. This can also be specified on a per-host basis in a configuration file.

X11 forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the user's X authorization database) can access the local X11 display through the forwarded connection. An attacker may then be able to perform activities such as keystroke monitoring.

-x Disables X11 forwarding.

-Y Enables trusted X11 forwarding.

If you're talking about ssh'ing to an OSX server, X11 forwarding should be enabled by default. To be sure edit as sudo /etc/sshd_config, uncomment #X11 forwarding no, change 'no' to 'yes', and restart sshd.

Finally, as you don't want to do X11 forwarding by default, you can automatically enable it per host by adding the following lines to ~/.ssh/config (create the file if it's not already there):

Host testbox
ForwardX11 yes

Change testbox to be the name or IP address of the host you are accessing.

Have I missed the point of this script?

You have to do all that X11Forwarding stuff you talked about on the ssh client or none of this will work.

Even if you do all that client X11Forwarding, if your "server" is not set up do X11Forwarding correctly it still won't work. When you ssh to a "server" the server sshd process sets the DISPLAY environment variable. If your log-in script resets it, ssh X11Forwarding won't work.

Finally I wasn't talking about sshing to an OSX Server, but to an OSX machine.

Actually you want 'ssh -Y' since Tiger.

Now that's a hint! I've been racking the Brain Housing Group over this one.
