Shawn, like some others have said: break the problem set into smaller more managable units. Get PPP working on the machine with the modem, then get your routing to other machines working. PPP can be troublesome, too many options amongst too many components(ppp, chat, modem-inits, authentification, ...). General strategy is to get modem connection up first by hand using minicom, observe type of authentification (can you enter username,password? or does binary ppp string pop out?) then invoke pppd with various guesses at options (pppd-command line, etc/ppp/options, etc/ppp/options.ttysX). Turn on pppd debug logging options: debug, kdebug 7. Look at /var/log/messsages for clues. Once link is established, try pinging the ip number of your DNS server, or the remote modems ip address. cheers, Karl. Shawn Fertch wrote: > Still looking for an answer to this.
