Re: open-source tool for filter out stats from dns logs

2013-01-02 Thread Carlos Vicente
Have you looked at DSC? http://dns.measurement-factory.com/tools/dsc/ It doesn't parse logs, but reads actual packet traces, and it reports many good statistics, with nice colored graphs. cv On Sat, Dec 29, 2012 at 11:56 AM, Gaurav Kansal wrote: > Dear Team, > > > > I want to collect some stat

So, if I understand you correctly, if I were to sign my authoritative zone and my caching nameserver, which is "bogus" for this zone, is dnssec enabled, and also validating, and no other validating nameserver is querying this bogus nameserver, then it's OK? cv On Thu, May 19, 2011 at 11:16 PM, Ma
