In fact, even starting the enlightenment config program causes ppp -auto to dial up. Same thing when sending mail from within mutt. Even though I have told sendmail to queue messages (sendmail -0 DeliveryMode=d -O HoldExpensive). Actually what it does is dial up, then stick them in the queue without delivering them. I assume that these are also caused because of DNS lookups. > > > > > > So anyway, I'd really like to be disable DNS lookups from causing ppp -auto to dial. How can I do this?

I'm not at all familiar with ndc's output so I guess you are referring to the stuff output by dumpdb - only there's so much of it. However, I've been running named with the -d1 flag and this seems to pick up all the requests in named.run. When Netscape was first installed, it reported that it couldn't find the host for 'home. netscape.com' (or something like this). I assume Netscape is configured to 'phone home, if only for the Netscape server to set a cookie... I cannot detect any current dns lookups for netscape.com. However, the following lookups are made when Netscape starts up now (output from named.run): news.force9.net usenet.force9.net usenet.plus.net.uk mail.force9.net relay.force9.net These are all for Messenger. They are produced as soon as the browser alone starts up (without even starting Mesenger). Since my ISP provides server-assigned addresses I am not sure I can put any of this stuff in /etc/hosts because the IP addresses change with each new connection. What do you suggest/ many Thanks, Ric To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
