It dials out as soon as something tries to send a packet out. Guessing (because this is what my machine does...) I'd say that you aren't running DNS, but do have your ISP's DNS server(s) defined in /etc/resolv.conf. There are 2 parts of the usual 'daily' shell script which will cause name resolution - 'mailq' and the 'netstat' command (I forget the parameters). Naturally, in order to resolve a hostname, the machine will send a request to your ISP - waking up ppp. 2 solutions - You could remove the offending steps from '/etc/daily' or, do what I do - set the modem to dial silently. That way it didn't wake me up... :-) > > It may have been sendmail trying to do uucp, but my uucp log shows no > activity for the past three days. > > Brian > John -- Beavis and Butt-Head; Vladimir and Estragon for the '90s. finger jbrann@panix.com for pgp public key
