I don't know does it really make a big difference if you run a http server on
port 80 or a napster server on port ..? If you ask me most Linux geeks and
their http servers probably cause a lot less traffic than Windows losers with
their file sharing.

Anyway if you own a domain then you could use a free dns server where you could
redirect your domain to a different port than 80 anyhow, can't you? Doesn't
every user get webspace as well so you could just direct your domain to the
webspace and the webspace then to your http server on some other port than 80.

 so as to avoid the conflict of them knowing you're gonna put up a linux box. Th
en once they leave it's as easy as plugging in the network values into your linu
x box, then plugging that into the cable modem. Give the cable modem a reboot an
d all should be good. If they've gotten smarter since I last dealt with the @hom
e people, you might have to use the same nic that they used for the initial setu
p. (only in the case if they hardcode the mac address in the modem. they never u
sed to) Then don't attract attention to yourself by leaving your box open for ju
st anyone to "walk into" secure it down. Only leave the ports open that are abso
lutely necessary for your operation. Plus if you plan on using your linux box to
 do IP masquerading, I think that is technically against their policy, but with
the dawn of all of the DSL/Cable modem "routers/gateways" put out by companies s
uch as linksys, this is almost !

however it's only offered in 3 cities and is expen$ive! @home for sure does not
block ssh, around here and I know they don't block ssh or UDP 500 out east. Anyw
ays, I hope this makes sense as I've been up for about 5 minutes, and hope it gi
ves you some useful information.
