Well, once the connection is made to your ISP, you (presumably) have to log in somehow and allow PPP packet mode to start. How does your ISP authenticate you? (PAP/CHAP, some login chat...) How is your ppp.conf set up to handle the login sequence? Please respond with the above stuff, and I'll help if I can. > > Thanks, > > Leonard > > P.S.

Network protocols are organised in sets of layers, the lowest being the network hardware, and higher layers piling on abstraction. See 'UNIX Network Programming' by Stevens for a description of several well- known protocol stacks. John -- Well, that's like hypnotizing chickens. finger jbrann@panix.com for pgp public key
