Installation
yum install net-tools
Finding out what processes are listening and on what sockets
netstat -nl --program
The --program option will list the PID/process path.
Scan Open Ports and Shut Down Services
netstat -tulpn
Options
-n
Show numerical addresses instead of trying to determine symbolic host, port or user names.
-l
Show only listening sockets (these are omitted by default).
-p
Show the PID and name of the program to which each socket belongs.
-a
Show the state of all sockets; normally sockets used by server processes are not shown. With the routing table display (option -r), show protocol-cloned routes (routes generated by a RTF_PRCLONING parent route); normally these routes are not shown.
