Hello, Tim.

I've set up Bio-Linux under Debian Sarge with XDMCP and VNC: You can get 
a Bio-Linux desktop using either the Microsoft Windows VNC viewer, or in 
a web browser window using the Java VNC viewer applet. Performance is 
excellent on 2Mb broadband - I'm using a web browser at the moment to 
run GAP4. I'm using 'TightVNC':


Instructions about setting up VNC under XDMCP are attached. You need to 
tunnel port 5901 (VNC) through port 22 (SSH) to use VNC through a 
firewall, and you also need to tunnel port 80 (HTTP) through 22 (SSH) if 
you want to use the Java applet in a web browser through a firewall. BTW 
these 'complications' are necessary to ensure security for external use, 
but are not needed within a firewall.

Best wishes,
