Dial on demand problem

Hi all,

I have configured my RedHat Linux AS 2.1 server to dial automatically (DoD). Anytime there is data my server will dial automatically, and everything is OK. But nowadays, I recognise that, my server dial automically without data. It makes me embarressing because no data needed to transfer but my server still dial. I guess some reasons following:
+ when anyone login my server (maybe telnet), as usual this user receives a mail "You have a new mail", so it make my server dial automatically.
+ when my server synchronize time, it sends packets by NTP protocols.
+ when sending packets to update routing table, like RIP protocols.

please help me to avoid this issue, I only want my server dial automatically when data needed to be transferred.

send me to
Thank you in advance!
