Open ports
- As a shell user there is a range of ports you may use to run services, this range is port 5000 to 5500. (Both tcp and udp)
Help! Someone is using my port!
- Ports are shared resources, if you're not using yours for a bit, someone else may take the port you were using before.
- If you have a good reason to lay claim to a specific port, please contact an admin and we'll see what can be done.
port command
- There is a custom made command available from your shell to check which ports are in use.
- This is the 'port' command.
Usage of the port command:
- port -a will show you the available ports
- port -s <port> will check if that port is available to you
Examples of how to use the port command:
- Find out if port 5001 is in use:
coolfire@Lydia:~$ port -s 5001 State for port 5001: In use Process info: - Done. coolfire@Lydia:~$
- What you can see here is that port number 5001 is in use already.
- You are not given any information about what process is running on the port as you are not root.
