I've got 12 servers in datacenter, but can login by SSH into one of them (facade server), other servers available only from it. In hosts file we have ip list each of available servers.

milkov@devel:/var/www/davel$ cat /etc/hosts
192.168.1.4 data1
192.168.1.7 data2
192.168.1.5 bground1
192.168.1.6 bground2
192.168.1.10 frontend1
192.168.1.11 frontend2
...

Question: How to know which one of servers serve this domain? How to find servers internal ip-address by external IP.

  1. How to find servers internal ip-address by external IP.

    You do not. Simple.

    THis is like asking "how do I find out who is the owner of a fuel station based on the phone number of the next shop". No correlation.

    Ineternal and External IP addresses are mapped by administrative decision - and that is it. Without access to the configuration file there is no way to get the relationship. Because there is no intrinsic one.

  2. I'm sure you have a few servers that you suspect that could be serving this domain. What I suggest you do, is connect to those. After remoting in visit a site like www.whatismyip.com and it will show you the external IP mapped to that internal IP. There are only 12 servers so should not take too long.
