Finding Network Status of specific process name

Question

I am looking for the cleanest way on linux to find the port status for a port being used by a specified program name via the command line. I have seen that netstat -p lists all pids but haven't seen anything corresponding to specific process names. Any help would be appreciated.

Answer 1

Theoretically you should see the program name with the paramter -p and the PID. Be aware that you need root rights to display the program name of processes which arent running under your user.

-p without root permissions:

$ netstat -lnp
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      -               
tcp        0      0 0.0.0.0:21              0.0.0.0:*               LISTEN      -               
...
...

-p with root permissions

$ sudo netstat -lnp
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1553/apache2    
tcp        0      0 0.0.0.0:21              0.0.0.0:*               LISTEN      1392/vsftpd
