I'm running Nagios on Solaris 9 via a Blastwave install (ie csw). According to my system, I have:
My problem is this. I have two WIndows AD servers. One of the services I checked on the AD servers was DNS. On Monday night, I re-ip'd both servers to another subnet (the same subnet for each server). Now when I check the DNS on one, it claims that the address I am searching for does not exist, while it's partner checks as working.
When I use the "broken" DNS server directly (ie a dig@) I get the correct information back. Similarly, clients using the DNS server routinely get valid information. So the indication is that the check_dns is not working for some reason, even though the DNS serve actually is.
Any ideas what might be wrong, or how I might go about fixing it?
