Xymon Server DNS

Hi All,

I imagine this is quite a simple one, and I'm overlooking something...but here goes...

I have Xymon 4.2.3 installed on Ubuntu; upgraded from Hobbit and it's been in production for almost a year now (including the time spent as hobbit). As our monitored network has grown, obviously the amount of lookups has increased with it. To try and speed up the tests I setup the Xymon server as a DNS server (slave for our domain, and forwarder onto the ISP DNS servers). Locally it works fine i.e. nslookup queries itself, and I can dig the DC and domain (again queried locally); from a remote machine I can also query the DNS on the Xymon server. However, Xymon reports the DNS service as down.

Any ideas?

Cheers, Phil
