I don't know if I can answer your question without further details on your setup, but maybe the following will point you in a general direction to look for the answer. The basic "problem" is you Demand Dialer is being triggered by something wanting an outside connection (bet you have already figured that out <g>). The usualy suspects when this happens apparently independently are DNS queries or attempts to get E-Mail from an outside server. Actually, the E-Mail request involves a DNS lookup too most of the time. I had one instance in Corel Linux where a dhcp client would always "trigger" a dial-out on boot up. This can be a hard problem to track down, and often proves to be a quite serious exercise in Deductive Reasoning! <g> I have even tried shutting down various add-on "services" not needed for the basic functioning of the system (like Exim, Apache, Samba, etc), to find the one that might be causing the dial-out. The fact that this happens on regular intervals would point to some sort of E-Mail query, IMHO. It also could be a result of a CRON job. In addition to this computer's Mail programs (Exim, Sendmail, Fetchmail, etc.), I would suggest you check ALL your E-Mail CLIENTS (Netscape, Outlook, KMail, etc) that have a capability to be setup to check for E-Mail automatically every few minutes. You should check ALL the computers on your LAN for this condition, as any computer on a network behind an IPMasq machine with Demand Dialing setup "should" be able to trigger a dial-out. A simple way to see if it is another computer is to disconnect the others and see if it still happens. You can hook them back up one-by-one to narrow it down to the culprit. A while back, my son was running a Napster-like program that checked his favorite sites periodically. He never told me he had it running & the first "clue" was un-explained dial outs. I would also check all your CRON scripts and make sure they are setup the way you want. Finally, take a look at the Demand Dialing scripts to see if there is a "re-dial" option that is set. It may be named something else. HTH & Cheers! -Don Spoon-
