What program is using which port?

I sometimes need to check that certain ports are free aka not occupied by other processes.
To find out I do a:

Code: Select all

sudo fuser -v 8080/tcp

This will show what program is using the port 8080 - in my case it is:

Code: Select all

~/ sudo fuser -v 8080/tcp
                     USER        PID ACCESS COMMAND
8080/tcp:            nobody     2151 F.... monitorix-httpd


Monitorix - so I cannot use this port to share my files etc with others.

If the port is not taken this command will report nothing as in blank.
