SOLVED After network change, no DNS to jails?

[AnejoDave]

So I moved. On a new network, I re-IP my Freenas, and the jails to new static IPs on the new network...but the jails don't seem to be able to reach their respective sites to check for updates. Odd.

Ping Google from the shell, that works.

Code:

 
[@FreeNAS ~]# ping google.com											   
PING google.com (172.217.6.110): 56 data bytes								 
64 bytes from 172.217.6.110: icmp_seq=0 ttl=53 time=20.501 ms				   
64 bytes from 172.217.6.110: icmp_seq=1 ttl=53 time=20.055 ms				   
64 bytes from 172.217.6.110: icmp_seq=2 ttl=53 time=20.279 ms				   
64 bytes from 172.217.6.110: icmp_seq=3 ttl=53 time=20.356 ms				   
^C

4 packets transmitted, 4 packets received, 0.0% packet loss					 
round-trip min/avg/max/stddev = 20.055/20.298/20.501/0.161 ms

Ping Google from the shell of a jail.... well, shit.

Code:

@sabnzbd_1:/ # ping google.com											 
ping: cannot resolve google.com: Host name lookup failure					   

Okay, how about pinging an external IP from the jail.... Yup, that works...

Code:

@sabnzbd_1:/ # ping 8.8.8.8												 
PING 8.8.8.8 (8.8.8.8): 56 data bytes										   
64 bytes from 8.8.8.8: icmp_seq=0 ttl=44 time=30.363 ms						 
64 bytes from 8.8.8.8: icmp_seq=1 ttl=44 time=30.763 ms						 
64 bytes from 8.8.8.8: icmp_seq=2 ttl=44 time=29.738 ms						 
^C

round-trip min/avg/max/stddev = 29.738/30.288/30.763/0.422 ms				   

All of my jails produce the same results, and the mail system can't reach out to send me mail, either.

Any thoughts on whats wrong?

Check the /etc/resolv.conf in your jail. You'll likely need to update it.

 

[pschatz100]

Has your gateway been properly set up after the network change? Make certain that your DNS servers are assigned correctly for the new network.

I had set the new gateway everywhere it asked for it. Monkey was right, the resolv.conf file wasn't updating.
