What did you get when tried Robert at thorshammer.org suggestion of
"If that works then try the IP of your netgear box."?

My /etc/resolv.conf only works when the ending lines contain this information:

### END INFO
search tx.rr.com
nameserver 24.93.41.125
nameserver 24.93.41.126

Take away the two "nameserver" lines and I can't resolve anything.
This is what happens when my Broadband line or Linksys router is down
at boot time.
DHCP writes an /etc/resolv.conf with only the "search" line in it.
Those two nameservers and IP addresses are automatically supplied by my ISP.

I run only workstations. I do not know about servers for sure.
You did say that this worked until just recently and we don't know what changed.
We''ll just have to fix it the hard way.

Alvin's suggestion makes sense. Try one at a time of those as Alvin suggests.

Another suggestion is to put the Knoppix CD in again and look at its
/etc/resolv.conf to see what works for it.
