My DNS server showing blacklisted in Nagios system

[imran_khan]

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:

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

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

Code: Select all

ping spamguard.leadmon.net
ping bhnc.njabl.org
ping dnsbl.solid.net
ping google.com

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.
