Verifying Which Ports Are Listening centos

1: access your server and type the commands

nmap -sT -O localhost

if nmap is not installed then first installed the nmap utility and then run the command again

yum install nmap

2: cat /etc/services | grep 834

3: netstat -anp | grep 4444

4: lsof -i | grep 834

hope this will help some one.
