Detecting Listening Network Ports
Detecting Listening Network Ports
One of the most important tasks is to detect and close network ports that are not needed.
To get a list of listening network ports (TCP and UDP sockets), you can run the following command:
netstat -tulp
Running a port scan from another server. (make sure that you have permissions to probe a machine):
# nmap -sTU
