But now when there is a problem reaching the DNS server (I have two in
/etc/resolv.conf) it spikes up to...
DNS lookups completed 1202825989.913910 40.001908
Is there any way to set the DNS resolution timeout to something
smaller? Has anyone tried running bind9 on the Hobbit box itself and having
it hold cache locally?
Hobbit does have a tendency of hitting DNS servers pretty hard. I would
definitely recommend using a local caching DNS server on your Hobbit
box. It is dead simple to setup, and it makes DNS lookups a lot faster
and more reliable.
As far as the timeouts are concerned, the bbtest-net(1) man-page lists
this option:
--dns-timeout=N (default: 30 seconds)
This assumes you're using Hobbit's built-in resolver library, C-ARES. If
you're running bbtest-net with the --no-ares option, there is no way
Hobbit can control the DNS lookup settings.
