I am trying to map one local domain with IP address by using Local DNS Server in Netborder SS7 Gateway - but gateway anyway is sending requests to the IP address resolved by external DNS Server, rather than Local DNS Settings.
I’m setting the IP Address/Domain through web-interface, then - when I’m checking the hosts file - it looks good:
10.1.1.10 company-call.domain.com company-call
So, domain company-call.domain.com - should be resolved on 10.1.1.10, and this can be proven by the ping utility:
But, when I’m checking with tcpdump - gateway is using IP Address resolved by External IP Address rather than from the local hosts file. How can i force the Gateway to use information from the hosts file?
This is resolv.conf file content:
[root@gw ~]# cat /etc/resolv.conf search domain.local options timeout:1 nameserver 127.0.0.1 nameserver 10.1.1.1
I tried also without “nameserver 127.0.0.1” - but the problem is the same.
Also, I didn’t found any DNS service running locally:
[root@gw ~]# netstat -lnp | grep '53' unix 2 [ ACC ] STREAM LISTENING 12534 2968/master private/local unix 2 [ ACC ] STREAM LISTENING 12538 2968/master private/virtual
