Hi!
Has anyone created a test to check if a specific IP is in a DNS based
black list?
It could be done with a DNS based test but you want the test to fail if
the entry is found and not if the entry is not found, i.e. Argus should
complain when the IP address is listed.
I guess that could be done with something like
Service UDP/DNS {
zone: 2.0.0.127.ix.dnsbl.manitu.net
class: IN
query: A
test: answer
nexpect: 127.0.0.2
}
but is there a more "elegant" way for multiple DNSBLs?
We want to keep an eye on the IP addresses of our mail servers and if
they are listed in the various black lists.
Greetings
