Strongbolt host xxxx.xxx 2(servfail)

I recently inherited a cobalt raq 3 with strongbolt on it.

After some basic setup, I have the machine running, but it will not resolve any host, such as if i

Code:

[root@missing ~]# host google.com
;; connection timed out; no servers could be reached;

my /etc/resolv.conf is

Code:

search left-nut.org
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 192.168.1.102

192.168.1.102 is the machine itself, port 53 is open, and forwarded at the router. The machine is running bind with no errors in the named.conf, or zone files. 8.8.x.x is google's public dns servers.

EDIT:
I get the connection time out when I comment out nameserver 192.168.1.102. I get the servfail error when it is not commented out. It will resolve the 2 host I have zones for, but nothing else.

Hi,

From what I've read strongbolt is based on centos, so I guess it works like any other box running linux.

The fact that you cannot reach google nameservers probably means that either there is a firewall blocking outgoing port 53 udp/tcp packets, or more likely you don't have a network interface, or gateway configured correctly. Try to ping 8.8.8.8 and see if you get an answer.
This also explains the servfail of your dns, if its configured as a forwarder for the domains it's not authoritative for.

Thanks. Was missing a default gateway setting. I had been fighting this problem too long, and hard to look at the simple things. lol
