netstat is notprimarily a *nix command. it's also in windows 95, 98, and NT(to my knowledge, i haven't tried any of the newer ms platforms).

However, since MS doesn't seem to particularly like people pokin' around, it's not really documented, kinda like ipconfig.

the syntax is:

netstat -a -e -n -s -p proto -r interval

the switches are:

  • -a Displays all connections and listening ports.
  • -e Displays Ethernet statistics. This may be combined with the -s option.
  • -n Displays addresses and port numbers in numerical form.
  • -p proto Shows connections for the protocol specified by proto; proto may be TCP or UDP. If used with the -s option to display per-protocol statistics, proto may be TCP, UDP, or IP.
  • -r Displays the routing table.
  • -s Displays per-protocol statistics. By default, statistics are shown for TCP, UDP and IP; the -p option may be used to specify a subset of the default.
  • interval Redisplays selected statistics, pausing interval seconds between each display. Press CTRL+C to stop redisplaying statistics. If omitted, netstat will print the current configuration information once.

hope this helps. =)
