How can you tell if there is problems with the first name server and it rolls to the second/third one? Is it logged?
Generally, no. Every query is resolved independently, because the resolver libraries are compiled into everything that knows how to talk to a nameserver and, only with rare exception, programs don't keep state internally. So if you ping www.joyner.ws, you'll open resolv.conf, try the first nameserver, wait 30 seconds for it to fail, then you'll try the second. Control-c, run ping again (which makes it resolve the name again, it's a separate process from the first time you ran it, obviously), and it'll go through the same process again. The big obvious thing is that stuff is really slow, and takes 30-45 seconds every time you look up a name.
Is there a command use to test resolving through a specific name server?
Sure, any of the command-line DNS look up tools are capable of this. Try looking up www.joyner.ws against the name server 209.42.192.253, as follows:
host www.joyner.ws 209.42.192.253 dig www.joyner.ws @209.42.192.253 (or god forbid) nslookup www.joyner.ws -server 209.42.192.253 Enjoy! Aaron S.
