I HIGHLY recommend you take advantage of SSH's ability to securely tunnel X connections, even if doing this over a lan. (It will also simplify and stabilize your firewall configuration, most likely). As close to "cook-book" as I get. The following should get you started. Please read relevant manual pages for more details. Install SSH on both machines (ensuring sshd is running on your Linux machine, to allow connections). It is not necessary to install an X server on your linux machine if all you want to do is allow client connections. Having XFree installed is enough. A functioning X server MUST be configured on your "client" FreeBSD machine. Assuming your linux machine is at 10.x.y.z, issue xhost 10.x.y.z on your FreeBSD machine to allow connections to be displayed. In X on the FreeBSD box, from a terminal, ssh to your linux box. (Note, if you absolutely must log in as root, you'll want to edit your /usr/local/etc/sshd_config to enable root logins). Check your DISPLAY variable in your remote ssh. Assuming your FreeBSD machine is at 10.x.y.p, use setenv DISPLAY 10.x.y.p:0. Note you should NOT use 127.0.0.1 or localhost here, as the remote machine will not resolve these to the FreeBSD box. Run your desired X applications, but do so over a fast connection, lest ye experience extraordinarily slow GUIs. > I have performed a half-baked scan of the documentation and > found a few references, but absolutely no details for > cook-booking the task.
