Displaying the Status of Sockets

Use the netstat command to view the status of the sockets on a local host. You can specify several netstat command options as a regular user.

Display the status of connect sockets as follows:

% netstat

Display the status of all sockets, including unconnected listener sockets, as follows:

% netstat -a

The output of the netstat command shows extensive statistics. The following example shows how you would limit the output to IPv4 sockets only.

% netstat -f inet
