I'd like to be able to find out which process is currently using a certain port in Linux. Is there any way to do this?

    On Windows, the command is : netstat -anb – djangofan Dec 11 '09 at 21:39

You have a couple of options:

lsof -i tcp:80

will give you the list of processes using tcp port 80.


sudo netstat -nlp

will give you all open network connections.

    lsof -i | grep {username} is also very useful, i.e. lsof -i | grep apache – LawrenceC Oct 30 '11 at 3:20

    For anyone wondering, -n : don't resolve names, -l : display listening server sockets, -p : display PID/Program name for sockets. – yellavon May 12 '14 at 15:18
  • I usually add -P to lsof -i tcp:$PORTNUMBER so that the port gets printed back to me as a number. – js. Jun 23 '15 at 8:42
netstat -lp

    on mac you have to add a protocol option to -p. so something like: netstat -lp tcp. – vrish88 May 25 '10 at 14:59

I am using "CentOS 7 minimal" which has nor netstat neither lsof. But a lot of linux distributions have the socket statistics command (i.e. ss).

Here is an example of execution:

# ss -tanp | grep 6379
LISTEN   0    128   *:*   users:(("redis-server",pid=2531,fd=4))

In Linux, To find a process running on a port, do below:

lsof -i :<port_number>


lsof -i :8080
