 This is the probe definition:

+ DNS

binary = /usr/bin/dig
lookup = www.yahoo.com
pings = 5
step = 180

 As far as I can tell by looking at the code, smokeping simply runs
 /usr/bin/dig @server lookuphost, which should simply issue a UDP probe.

 Hhm. It looks like the remote server cannot resolve Internet queries.
 WTH have our NOC been up to? Need to investigate ...
