mydns + resolving external domains

Hi All,

I followed the hot to forge to install ispconfig 3 and followed the link "http://www.howtoforge.com/mydns_mydnsconfig_dnsmasp_on_ubuntu_edgy" for mydns to resolve external domain like google,yahoo etc. This is not working at all.

Please advice on this.

Tks

You need put resolver IP in mydns.conf at line:

recursive = your resolver

 

Hi

Tks for the reply. But domains hosted locally should be resolved by the local mydns. When I put recursive to a DNS IP the ispconfig server tries to resolve local hosted domains also from that. how to avaoid tha please?

and what's the syntax to add more than one resolvers?

 

you have to use the , e.g. : recursive = 192.168.0.1 , 192.168.0.1

 

I tried both my VPS providers internal + external DNS IP in the recursive option, both without any results. All was working fine and it just died out of the blue.

 

Try 145.253.2.75.

 

Code:

root@us1:~# cat /etc/resolv.conf
#nameserver 64.85.160.4
#nameserver 209.165.240.227
#nameserver 208.67.222.222
nameserver 145.253.2.75
root@us1:~# ping google.com
ping: unknown host google.com

 

Code:

root@us1:~# ping google.com
ping: unknown host google.com
root@us1:~# ping -c 1 203.16.214.27

I just can't seem to get it to resolve external DNS's. I've got 3 other VPSs all setup using the same guide, even one in the same DC.

 

What happens if you use your router's local IP address in /etc/resolv.conf? Normally router's run a DNS server/cache.

 

It's hosted in a kansas city DC. The first two IP's in the resolv.conf are the internal/external DNS server's for my VPS provider.

 

Maybe a stupid idea, but has you VPS provider setup some form of firewall?
Or do the dns'es have stopped answering to your server?

I know, our company does block ip's querying our DNS'es more then avg. (eg. 35.000x a day)
