Re: Newbie can't log into his own wu-ftpd server from PowerBook G4 (Mac OS X 10.2.8)

To test.... connect your dialup - point to you ISP's DNS servers  - and
attempt your connections.  It's ok that it doesn't resolve - just that the
wu-ftpd gets an answer within a reasonable time.  That will confirm the
theory.

There are a number of devices that can operate as a DNS server.  Setting
it up isn't difficult...  but will take some effort.
