1. How do I display remotely on my computer?

On your OS X workstation, launch X11 (/Applications/Utilities/X11)
and type ssh -X [username]@[remote_machine]. Enter your password when prompted. Try something like xclock & to see if the display works. Note, if ssh -X doesn't work, try ssh -Y which may be more comatible in some cases.
2. Is there dial-up access/ppp for KITP from my laptop? Ask the KITP Helpdesk to setup a PPP account for you on the KITP modems and to obtain the dial-in phone number . Use your current Unix username and password to get in. For Win95/98 and Mac computers the setup is straightforward. If you have a Linux box, or special dialup software, you might be asked for a port password after dialing up. If this is the case, contact the helpdesk, and they'll drop by with the password.
