Re: No DNS cache - Wirezfree - 04-22-2016
If you are feeling really geeky,
and want to test dns out.??
namebench is available in synaptic...
Re: No DNS cache - firenice03 - 04-22-2016
One other to try...
Check /etc/nsswitch.conf file... Look for..
Code:
hosts: files mdns4_minimal [NOTFOUND=return] wins dns mdns4Within that line, "wins" is mentioned..
Change the order to:
Code:
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 winsAs suggested here:

Update: Another thought
Something else to try, try turning off IPv6

Wirez: I gave namebench a spin (I ran it when the problem first arose as well). But I don't see any report. It ran twice in GUI mode, finally I killed it, with nothing to show for it. I did run raw pings on the nameservers back then, and found them all close in speed.
Fire: I found the 'mdns4" spec missing from that line and added it. Otherwise the desired order was already there. I think I'd like to leave IP6 in place, as soon it probably will be necessary.
Thanks guys.

paul1149,
In reply #5, you mentioned you think this is solved. If so, could you mark this thread as such?
Re: No DNS cache - paul1149 - 04-22-2016
Done. Sorry, I forgot about that.

@paul1149
Do you have Chrome Browser installed.??
IIRC it will only show results if it detects you have Chrome browser default.??
Re: No DNS cache - paul1149 - 04-22-2016
That's a pretty weird qualification, it seems. I have a couple of chromium derivatives, one set as the system default.
Re: No DNS cache - Wirezfree - 04-22-2016
O.K, not sure then why it won't show results... mmm

If running better you're probably good... If you're feeling squirrelly you could disable (1) then enable (0) - for testing..
This is what gave me the idea..

yeah its Windows, but same idea ;D ;D ;D ;D
Re: No DNS cache - paul1149 - 04-23-2016
I've been getting a little bit of regression on this (though it's still a lot better than it was, and some of it might be evening cable lag), so I decided to give that a try. Under the network connection I set IP6 to "Ignore", which grayed out the rest of the settings, so I guess that equals "off". I didn't see any change in dns speed, though, even after rebooting.
