Hey Alex,
I imported some DNS tests with commands similar to this
Method = DNS
Title = DNS: Yahoo
Server = <DNS SERVER ADDRESS>
Protocol = UDP
Port = 53
Timeout = 60
Hostname = http://www.yahoo.com
Interval = 3600
and they all come up bad.
Now if I go into the GUI and click on one of the tests and click EDIT and then click APPLY the test will come up green and ok.
