Often times, it can be useful to inspect the state of socket connections made by applications.

You can use the tool ss to inspect and even kill connections.

$ ss # See a list of all sockets
$ ss -t -p # See all TCP sockets with process information
$ ss -K -t '( dport = :6514 )' # Kill all TCP connections open to destination port 6514
$ ss # See a list of all sockets
$ ss -t -p # See all TCP sockets with process information
$ ss -K -t '( dport = :6514 )' # Kill all TCP connections open to destination port 6514
