I take it by your email address that you are dialing into the iprimus network in Australia. I had problems connecting linux to iprimus dialup routers, and was informed by iprimus that the "do not support linux". The problems I had were constantly breaking dialup connections and problems establishing reasonably long lasting TCP connections (no RST or FIN packets. The stream just stopped). I would suggest turning on debugging on your PPP connection. Go pppconfig and under your connection choose advanced, and then switch debugging on. >From the debug info in syslog I saw constant CCP negotiation errors and problems (Compression Control Protocol). I fixed this by forcing off BSD and deflate compression on the connection. Edit /etc/ppp/options and add in these lines bsdcomp 0 deflate 0 noccp restart ppp and make sure that the CCP errors no longer appear in your ppp debug output. Although this removes the compression, it won't slow your link to much as you think as the modems will still have their LAP-M or whatever its called. Basically when iprimus says "we don't support linux" they mean, "we don't debug our dialup routers, if windows dials OK, then its OK, right!" Let us know how you go. Kind Regards Crispin Wellington
