This could be any number of things, what services are you running on the server? My guess would be something trying to resolve a hostname. I can't think of an easy way to find out what is causing the dialout, but here are my suggestions. 1) If it exists have a look in /proc/net/ip_conntrack (Existance depends on whether or not it was compilied into the kernel. 2) Use ipchains/iptables to log (and perhaps deny) any outbound traffic on the ppp link, this will at least show you what it is trying to connect to at the other end. 3) Iptraf (or the like) may also be a helpful program. > This is my connect string : > usr/sbin/pppd connect /usr/sbin/chat -v -f /etc/ppp/default > This is my options file: > /dev/ttyS1 57600 crtscts noipdefault demand defaultroute idle 1500 You might want to add persist to the options, else pppd will drop the connection after it is finished the current transfer. You might also want to set maxfail to 0, otherwise it will default to 10 and I believe shutdown should it fail to connect ten times in a row. Cheers, Malcolm V.
