Nagios Support Forum

Hello,

My DNS server showing blacklisted in Nagios system but when it checked from the various web site and showing this ip is not listed. Please suggest me on the same.

CHECK_RBL CRITICAL - (3 servers timed out: spamguard.leadmon.net, bhnc.njabl.org, bl.technovision.dk) (dnsbl.solid.net)

Thanks,
Imran Khan.

The blacklist check is not critical due to your server being blacklisted, but due to timeouts trying to reach the blacklist servers:

Can your nagios server ping these servers, or in general just reach the internet?

Hello,

Correct. My server is not blacklisted, getting server time out error with RBL list domains.
I have removed dnsbl.solid.net domain from the check_rbl command definition after that this error gone from the nagios system.

Thanks,
Imran Khan.

No problem. Enjoy the week.
