in theory
in the real life you have no control of the order in
whci namesvers from /etc/resolv.conf are used and mostly
theay are all get the request and the faster response is used
mixinig different dns-views leads to rendamloy get different
results and if your ISP's namesevrer is a crap with unstrustable
responses for NXDOMAIn you are playing games with your network
It looks like it is random ... I took all the dns server addresses
out of the router leaving only 127.0.0.1. That leaves my local dns
plus whatever Viasat uses which is terribly slow today. I never saw
anything like this before.
Some sites have a bunch of look ups, like "weather.com" which I have
been testing with because it does a lot of them. It is obvious when
it hits the ISP dns server and sits there for 20 - 30 seconds, maybe
more worst case, the local is instantaneous. I can't be certain but
that's how it looks to me based on what you have told me ...
I rebooted this computer just to be safe and shows resolv.conf:
[bobg@box7 ~]$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.1.1
nameserver 127.0.0.1
nameserver 184.63.128.68
I guess that's ok? The last one is the ISP dns, or at least I don't
think I have that entered anywhere. 192.168.1.1 is presently a
Buffalo wireless router running dd-wrt. It is the dhcp server.
A call to Wildblue tech support produces a warning of long wait
times. I guess there are others complaining. I wont learn anything
there today except that they are probably swamped with complaints.
Thanks,
Bob
