privacy / SSH and X11 forwarding

[Kevin T.Broderick]

On my OS 10.3.2 setup, /etc/sshd_config and /etc/ssh_config are
the appropriate files to modify, and X11 forwarding is off by default
(but can be turned on by changing those two settings--ForwardX11
in /etc/ssh_config and X11Forwarding in /etc/sshd_config.

And restarting the daemon under OS X can be as easy as hitting
"Stop" and then "Start" for "Remote Login" under System Preferences
-> Sharing.  You can probably also do it the Unix way, if you prefer
(kill -HUP `cat /var/run/sshd.pid`),

And, as someone else noted, this is *much* *much* better than
xhost +, which opens you up to X11 connections from anyone
who can get past your firewall.
