Re: Using DSL connection.

Thanks for the message.  I did download RPPPPoE and installed it, and I am now
connected.  One question remains though, that is, although I can use telnet and
netscape, ftp and ssh do not seem to be working at all.  Where should I look for the
cause of the problem?  Thanks!
