Initial Description





Filters for tcp and tcp6 lines, so omits udp and unix sockets.

Information is gathered from /proc; this uses netstat mainly to format it.

Gives output like:<tt><pre>     21 tcp LISTEN
     12 tcp ESTABLISHED
      7 tcp6 LISTEN
      1 tcp TIME_WAIT</pre></tt>









Initial Title
