Any good ideas

[The Buda]

Recently I set up linux on my old computer, got it running nice and solid (as all linux boxes should) set up the apache, FTP, set up my router to send all incoming requests for http, ftp, and telnet to my linux box and updated all my errata.

I tried to access form my computer directly to the linux box and bingo, another triumph. Same thing with the router. But alas, poor yorkic, in the outside world can not access my server, for you see Comcast doesn't allow it.

Comcast doesn't allow http, ftp, irc, mail, dhcp, or any otehr useful servers to run on it's network. All I have left is a dollar, a dream, and the ability to access my machine from the outside world with telnet.

So what are my options here. What good is my machine as a server. can I use telnet to secretly make somesort of download server. Can I use this server in any way shape or form with my webpage on the outside world? The way I see it now, it's good for practicing perl on, compiling the one or wo programs a year that I right, and rebooting from the otehr side of the apartment just becuase I think it's cool that I can type reboot -n and hear the beep of the reboot a few seconds later.

so ...

1) how is DSL in an old apartment building where wires have not been updated in lets say 15 years.

2) what good is my server if i don't find a way to conect it to the outside world. is telnet good for anything worth spending my time setting up?

You can run an ftp server on port 21 just as easilly as running a telnet server.

(Admins try firewall ports off but the thing they don't seem to realise is that people are just going to move their other services to the unblocked ports. In the short term it blocks the ports but in the long term it just creates chaos for themselves.)
