NETSTAT

Netstat is an application available with some computer operating systems that displays information about the networking subsystem. Uner Linux, the default for
netstat is to display a list of all open sockets. Under Linux netstat can be usefully used by web site system adminstrators to view the number of concurrent connections to the web server, for example with the command:
netstat -na
grep ^tcp
wc which filters out any non-tcp connections by using the grep program. Further, a simple count of the number of concurrent connections can be retrieved by again using netstat and piping its output through grep, so:
netstat -na
grep ^tcp
wc -l
