Reverse DNS stopped working after upgrade to 5.7

[damindd]

We have a few reverse DNS services that quit working after upgrading to 5.7.

The check command is check_xi_service_dnsquery

The Command View is $user1$/check_dns -H 10.0.0.2 -a 'name = dnsname.com.' -s dnsserver_IP


Did something change with check_xi_service_dnsquery requiring a different format?

Thanks.

Additional info:

check_dns v2.3.3 (nagios-plugins 2.3.3)

bind-export-libs.x86_64 32:9.11.4-16.P2.el7_8.6

Results from manual run:
[root@nagiosxi /]# /usr/local/nagios/libexec/check_dns -H 10.0.0.2 -a 'name = server1.domain.com.' -s 10.0.0.5
DNS CRITICAL - expected 'name = server1.domain.com.' but got ''

Hi @damindd,

It looks there was a minor syntax change in the latest version of the plugin. Try adjusting your check command as follows and let me know if that works on your system ( remove the name = from the expected address and add the -q any option to the command string).

Code: Select all

check_dns -H 10.0.0.2 -a 'server1.domain.com.' -s 10.0.0.5 -q any
