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 -aExample 1-3 Displaying Connected Sockets
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 TCP: IPv4 Local Address Remote Address Swind Send-Q Rwind Recv-Q State -------------------- -------------------- ----- ------ ----- ------ ----------- system-1.ssh remote.38474 128872 0 128872 0 ESTABLISHED system2.40721 remote.ldap 49232 0 128872 0 ESTABLISHED
