re: Dennis Peterson [email protected] "nslookup geneslinuxbox.net.multi.uribl.com" is only going to tell someone where the first (of probably many) layered DNS servers are. Ubuntu 12.04 (LTS) takes this to an extreme by running a cacheing name server on the desktop. i.e.:
Unfortunately, I'm not aware of a traceroute like equivalent for DNS that will let me query intermediate caches without already knowing where the intermediate caches are. (I happen to know where most of my intermediate caches are.) "nslookup" on Ubuntu 12.04 (LTS) shows: $ nslookup geneslinuxbox.net.multi.uribl.com Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find geneslinuxbox.net.multi.uribl.com: NXDOMAIN (I happen to think Ubuntu's design here is brain damaged.) I queried Google's public name servers at 8.8.4.4 and 8.8.8.8 and they're returning the right value (NXDOMAIN), as are Comcast's at 75.75.76.76 and 75.75.75.75 . The DNS servers listed for the domain OITC.COM are configured so that they ignore me when I ask about things they're not authoritative for, which is the right thing to do - but they might give you different answers. --- Richard Conto On Thu, Feb 6, 2014 at 4:51 PM, TR Shaw <[email protected]> wrote: > $ nslookup geneslinuxbox.net.multi.uribl.com > Server: 10.0.1.1 > Address: 10.0.1.1#53 > > ** server can't find geneslinuxbox.net.multi.uribl.com: NXDOMAIN > > On Feb 6, 2014, at 4:48 PM, Dennis Peterson wrote: > > > I'm not part of your problem or your solution.
