DNS lookup fails connecting to server on same network

[Dan Lund]

The file shouldn't update on reboot, it should only update when
dhclient (or whatever DHCP client style is used in your distro) snags
an IP and DNS information from the DHCP server.  Pretty much that's
what determines what goes into the /etc/resolv.conf.

I mean, you could edit the /etc/dhclient.conf (again, assuming your
using dhclient for DHCP initialization), or just edit the
/etc/resolv.conf, toss it to ./etc/resolv.conf.saved and if it goes
fubar then copy the /etc/resolv.conf.saved to /etc/resolv.conf.
(VERY ad-hoc and amateur but a quick fix)

In theory though, you should be able to bounce between DHCP address
changes network to network without a problem.  This is the exception
because DHCP update is causing a problem somehow.  The main culprit is
probably one of the router's DNS server address allocations perhaps.

Great I wait until the end of this then read your using Debian. hah...
I forget how that works but if I remember right it uses dhcpcd...

Thanks,

If you need more than 3 levels of indentation, you're screwed anyway,
and should fix your program.
