It's also the most secure and simple way to run X programs remotely. This is usually as simple as running it with the -X option. Check the X11 and TCP forwarding section of the ssh man page for details. If you want the party at the other end to also see what you're running, keep reading. > 2) Show them a program I'm running on mine. Both console and X. In console, you want to be using screen - kind of a window manager for the terminal. Run your programs inside screen, and the other party will be able to log in to your machine with ssh, and connect to your screen session in a listen-only mode. Again, check the man page for details. An alternative that I've never used before is vtgrab. The easiest way I've found in X is with VNC - an alternative to straight X11 that will feel very familiar (but a little slower) if you've ever used Microsoft's terminal server. The vncserver will start a seperate X server that you will both need to connect to. There's a program called rfb which will export your current desktop, and it also has a listen-only mode. > 3) Do it securely over the Internet. You can tunnel console, X and vnc traffic over ssh. Read the ssh man page or the full online manual at the OpenSSH website for details on TCP forwarding. Or you can look in to setting up a VPN connection. Much more flexible, but will take a bit more work to get off the ground. For two Linux machines, I'd suggest freeswan (http://www.freeswan.org/), because it's what I know best. Somebody else may have other suggestions. > 4) Transfer files (besides attaching to email). Do I need to set up an > ftp server on both machines? No. The ssh package will include sftp - essentially ftp over ssh. It will also have scp, to securely copy files back and forth. > 5) Can I do 1, 2, and 3 for more than one person (I'm the Alpha Geek in > my family). Both screen and vnc will let multiple clients connect. Bandwidth may start to become an issue with multiple vnc clients. -- Pete -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
