[smokeping-users] dig options to prevent bind caching?

Hi all,

we are using the dns probe to monitor local dns servers as well as name 
resolution of internet url. The internet name resolution is done with 
the url www.ibm.de

Today, we had some problems with our name servers. We used dig at the 
command line and received some timeouts, that is, no successful 
resolution. We tried this several times using different urls. At the 
same time, the rrd graphs for www.ibm.de did not show any deviation from 
the normal behaviour.

We assume at the moment, that dns caching might have ocurred. In this 
case, there wouldn't have been any real name resolution, but only a 
cache lookup.
Are we right?
Is there an option to prevent that behaviour only for the dig probe (we 
already looked at the dig options, no clue)?

Any other suggestions?

thanx for your help
