Re: WAS: a few question about IP-MASQ, IS: weird dial-ups



Hi,

I have a similar config, but use diald instead. I have the same effect,
too. I found out that all those dial-up's are to talk to the
name-server. It seems to me that the problem is that some programs want
to do a reverse lookup on who's trying to connect and it seems that
/etc/hosts isn't enough. Try using mailq from a remote machine. My Linux
ALWAYS dials the net for a reverse lookup, fails of course (my net is
192.168.11.0), and then mailq prints error msg on syslog that it
couldn't find out who is 192.168.11.10 or something like it.

I think setting up your own caching DNS server should solve the problem
though I didn't yet get around doing it.

Please mail me if you find any solution/hints to this problem
