Need help with a DNS problem
Hi,
A few months ago I posted the enclosed message and was given the fix to turn off ipv6
support,
which has worked fine for me ever since (i.e, add the line 'install ipv6
/bin/true' to /etc/modprobe.conf)
Recently the DNS problems I described have come back... I did upgrade a new kernel using
yum.
I still see the ipv6 line in my /etc/modprobe.conf file so I am at a loss. Any ideas as
to what may
be causing resolver "dropouts"??
Regards and Help!

Howdy,
I am having a strange issue on my new Fedora Core 2 install with DNS.
I have three systems connected to ADSL via a Netgear WGR214v2 Router,
with one running Redhat 9, one running FC1, and the other my new FC2 system.
The Redhat system is running dhcpcd and has no problem getting addresses.
The FC1 system is running dhclient and had no problem getting addresses.
The new FC2 system is also running dhclient and fails to get addresses for only
a *few* names I've encountered so far. And dig will give me an answer for those
names, but nslookup will fail. I have looked up everything I know and compared
the FC1 and FC2 systems and they look to be configured the same.
For example,
% dig myfidelity.members.fidelity.com
; <<>> DiG 9.2.3 <<>> myfidelity.members.fidelity.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 3837

Server: 192.168.0.1

** server can't find myfidelity.members.fidelity.com: NXDOMAIN
Oh, and I forgot to mention that every now and then nslookup will return an address for
myfidelity.members.fidelity.com,
but that is not the typical case.
Any ideas?
Regards,
Allen
