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
...
Also I've domain megaplan.tvigle.ru (IP 79.142.100.36).
Question: How to know which one of servers serve this domain? How to find servers internal ip-address by external IP.
PS: Sorry about my Eng. lng
