Reverse DNS Failure

[wneville]

Hello,

In one of our servers we can nslookup x.x.x.x and get the DNS name resolved. However, in another server reverse DNS is not working. We need this to work in order to get host names from Autodiscovery jobs. Any idea why this may be working on one and not the other?

Cheers

Hello @wneville

Thanks for reaching out, the DNS server is responsible for name resolution, and recommend taking a look at the DNS server config/logs. Are you able to resolve this same server from any other on your network?

If the IP address on the server is static you can add the name/address to '/etc/hosts' so that your Nagios XI is able to resolve using the local config.

Thanks,
Perry

Thanks Perry! All set on our end and you may close this. Apologies!

Excellent @wneville, I will go ahead and lock this one up then.

Thanks,
