some service is causing DNS query and therefore dial out

[DJ Boris]

hi there,

I am having a problem tracking down "something" that triggers a dial out on
my

FreeBSD 4.7-RELEASE FreeBSD 4.7-RELEASE #0: Wed Oct  9 15:08:34 GMT 2002
root at builder.freebsdmall.com:/usr/obj/usr/src/sys/GENERIC  i386

It is somethign trying to do a DNS query

Apr 24 00:01:42 fbsd ppp[45]: tun0: TCP/IP: OUT UDP:
xxx.xxx.xxx.xxx:1040 ---> xxx.xxx.xxx.xxx:53 (44/72)

Apr 24 00:01:42 fbsd ppp[45]: tun0: TCP/IP: OUT UDP:

xxx.xxx.xxx.xxx:1040 ---> xxx.xxx.xxx.xxx:53 (39/67)

Apr 24 00:01:42 fbsd ppp[45]: tun0: TCP/IP: OUT UDP:
xxx.xxx.xxx.xxx:1040 ---> xxx.xxx.xxx.xxx:53 (50/78)

Apr 24 00:01:42 fbsd ppp[45]: tun0: TCP/IP: OUT UDP:
xxx.xxx.xxx.xxx:1040 ---> xxx.xxx.xxx.xxx:53 (50/78)


I have sendmail but I have removed the "-q" flag so I only call that from
ppp.linkup file. how can I track down what this service is? can anyone give
me any ideas? this server is alone on the LAN at the moment?

I have a DNS server running but I have heartbeat-interval set to 0.

I have spent hours looking through the logs and tracking the times but I
don't seem to be able to identify what is causing this.

can someone help me out here? what conf files do I need to give you?

thanx a lot
