[dns-operations] Access to DNS-Logs

[Michael Friedrich]

Hi,

that is why you are using the judy library [1] with specialized dynamic 
arrays in the ncap module mod_urstate right?

Considering the fact that the ncap can be enhanced and enriched by 
several modules, loaded dynamically at runtime, maybe someone could 
catch up by building a module which is buffering data output to a 
database. I haven't looked up into this direction but I'm pretty sure 
there also will be performance and memory issues. And besides - if 
you're on Linux do not try to pipe ncaptool output into a parsing perl 
script (not the one provided but a much more enhanced version with 
qr-matching)... it was worse than expected...

Either way dnsmezzo looks nice and I will watch it ;-)

Kind regards,
Michael
