Ping hostname doesn't work

[Antonino89]

Hi guys,

I have 3 virtual servers, after i edited the /etc/hosts file i'm not able to ping the hostname of the other servers on the cluster but i can ping the IP address.

root@Server1:~# more /etc/hosts
Server1 192.168.100.11
Server2 192.168.100.12

127.0.0.1 localhost
Server3 192.168.100.13

root@Server1:~# ping 192.168.100.13

/etc/hosts is based on "IP name" pairs not "name IP".
