To run an FTP server you need software...
I reccommend BulletProof
, but you can find other free software out
there. Any FTP serving software will do... just make sure
to follow the instructions carefully, ESPECIALLY of you
are behind a firewall!! Another good thing to have if you
decide to run an ftp server is DynDNS
it gives you a free hostname (Ex: you.dyndns.org) which
updates automatically to your new ip address every time
it changes (like when your connection resets).
