[Nagiosplug-devel] check_dns

[Richard Mayhew]

Hi, Good to hear from you,

Yup sounds like a plan, I think the best plan would be to change state if
the ip returned doesnt match either of the specified possible ips.

*grin* Think we could get a test version of this out sometime?

Thanks

Richard.

Richard,

This is a good idea. I was thinking that we should use multiple -a
arguments to specify more ip addresses (eg "check_dns -H ibm.com -a
10.10.10.1 -a 10.10.10.2").

For the comparison between the expected ips and the returned ips by the
nameserver, I presume we consider it a failure if all the ips are not
returned (order independent)?
