] "sas.ne2.attbb.net" into both the "HTTP Proxy" and "SSL
] Proxy" fields of the Edit-Preferences-Advanced-Proxies
] section, and put "8000" in both respective "Port" fields.

] ", .ne2.attbb.net". In Internet Explorer, it is

] are supposed to put in "*.ne2.attbb.net". Netscape is

Fucking Comcast. Instead of registering a MAC once, they do some kind of dynamic registering thing where you have to go through proxies etc to "Register" your connection. I have to do this every year or so. It varies. The comcast support chick was giving me alot of flak about Linux, so Fuck her. Basically just setting up proxies so they can see where on the network you are coming from. More of a note to myself when I have to do thing again, but here are the instructions for doing it under Linux
