hi
iptables -L shows udp port 1514 is open

since the question i asked is about how to open port in linux i will close this question and open new question regarding ossec issue

You don't "open" a port in Linux. It is OSSEC that listens for connections on a particular port. Try disabling iptables to rule out the port being blocked /etc/init.d/iptables stop.

Did you run netstat -atup ?

Don't filter just for "LISTEN" as you may have a connection that is in the "ESTABLISHED" state.
