I appear to be having a few problems with the setting up of a DNS. We have
a reasonably sized network
of ~150 machines, and have a local DNS which does lookups for those, and
passes the rest out onto the
net. This is not the problem, this bit works fine. The problem being that
the DNS query to the outside
world doesn't force the router (A cisco 761, with demand set to threshold 0,
time 0 ) to dial and connect.
Any suggestions for why it won't call? (is this a router config problem, or
All I can think of is that the router requires a tcp request to dial (afaik
DNS is udp?)
So far, my idea is to have ipchains log requests for dns lookup, and have
some monitor script ping a known
outside to force the connection whenever the dns does stuff. The problem
with this is that is the link is already
up, its pointless.
Anyway. If anyone can help, i'd really like to hear about it. I doubt any
suggestions could be much worse than mine
Thanks in advance
