Excellent
remote control and
screen sharing software system published by
Farallon (aka
Netopia).
Timbuktu has been around for yonks, as early as the early 1990s as far as I remember. The app works as both client and server in one on any class of Mac OS or Doze computer.
A simple connection menu allows communication with another Timbuktu box via IP Address, AppleTalk or whatever that Doze stuff is. Once authenticated (a highly tokenised process, which enhances security) the remote desktop appears in a window. It's cursor is your cursor. Whatever you can do via software on the connected-to computer can be done by you via this window.
Very very useful to run headless servers in a multi platorm environment (with the most notable exception of Linux, of course, as Timbuktu has not been ported. But hell, that's what The X Window System was built for...)
Recommended.
