Please let me know if you need any additional information.
I am able to access the head plugin in Windows 7 without any issue, but I can't able to access the same in Linux.
EDITED...................................
Port 9200 is not reachable from outside,
[root@ newvm ~]# nc -vz vmname 9200
nc: connect to vmname port 9200 (tcp) failed: Connection refused
Whereas the port is LISTENING with in the VM,
[root@vmname ~]# nc -vz vmname 9200
Connection to vmname 9200 port [tcp/wap-wsp] succeeded!
[root@ vmname ~]# netstat -nat | grep :9200
tcp 0 0 ::1:9200 :::* LISTEN
tcp 0 0 ::ffff:127.0.0.1:9200 :::* LISTEN
I have disabled the firewall and tried, but the issue still exits!
