How do I find out what ports my UDP is listening to?

Check Listening Ports with netstat

1. -t - Show TCP ports.
2. -u - Show UDP ports.
3. -n - Show numerical addresses instead of resolving hosts.
4. -l - Show only listening ports.
5. -p - Show the PID and name of the listener's process. This information is shown only if you run the command as root or sudo user.

Is netstat real time?

Does netstat show hackers?

What is TCP vs UDP?

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.

How do I get a list of UDP ports?

In the above command, the flag:

1. -t – enables listing of TCP ports.
2. -u – enables listing of UDP ports.
3. -l – prints only listening sockets.
4. -n – shows the port number.
5. -p – show process/program name.
