Weird DNS issue, NRPE [ Edited ]

[#1]

HI,

Today I changed DNS servers on our CentOS nagios install and all of my checks are still communicating except for one.It uses check_cpu_stats via NRPE.The check actually succeeds when I use the IP address of the host, but fails when I use the hostname (or FQDN).So, DNS right? The weird thing is an nslookup resolves the host correctly, using the new name server.I thought it was a cache issue, but the correct IP seems to be showing. Also, other NRPE checks on the same host (using DNS name) succeed.I'm puzzled! Any input or thoughts are greatly appreciated!

Please help.

I did not find the right solution from the internet.

What's the relation to infoblox?

From your description, it is not clear how your DNS is setup. If you are using Infoblox servers for your DNS, you may want to open a case with Infoblox Support and they can help you debug this issue. If you are not using Infoblox for your DNS services, then you would want to request help from your ISP.
