To setup FINK on the Durham network you need to make sure that it can talk to the outside world bia the Durham proxies.
First, you need to download Fink.
It's pretty straightforward and just follow the instructions on the download website. You should also install the FINK Commander (GUI based FINK)
This all works fine until it tries to speak to the outside world (when you get to the "scanpackages" step).
You need to set up the correct proxies for Durham. Although there is a place in the Fink Preferences (in the FINK Commander) to do this, it does not allow FINK to tunnel through the firewall for updates etc.
To do it properly, go to the command line and type "fink configure". This will run a terminal-based routine that will ask you a whole bunch of questions. For most of them you can just use the default (just press enter without entering anything). The only thing you have to do is that when it asks "Enter the URL of the HTTP proxy to use..." you enter:
When it asks if you should use the same proxy for ftp you should reply \"Y\" (for Yes!).
