Displays protocol statistics and current TCP/IP network connections. NETSTAT -a -b -e -f -n -o -p proto -r -s -t interval ...

Displays protocol statistics and current TCP/IP network connections.  NETSTAT [-a] [-b] [-e] [-f] [-n] [-o] [-p proto] [-r] [-s] [-t] [interval]    -a            Displays all connections and listening ports.   -b            Displays the executable involved in creating each connection or                 listening port. In some cases well-known executables host                 multiple independent components, and in these cases the                 sequence of components involved in creating the connection                 or listening port is displayed. In this case the executable                 name is in [] at the bottom, on top is the component it called,                 and so forth until TCP/IP was reached. Note that this option                 can be time-consuming and will fail unless you have sufficient                 permissions.   -e            Displays Ethernet statistics. This may be combined with the -s                 option.   -f            Displays Fully Qualified Domain Names (FQDN) for foreign                 addresses.   -n            Displays addresses and port numbers in numerical form.   -o            Displays the owning process ID associated with each connection.   -p proto      Shows connections for the protocol specified by proto; proto                 may be any of: TCP, UDP, TCPv6, or UDPv6.  If used with the -s                 option to display per-protocol statistics, proto may be any of:                 IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.   -r            Displays the routing table.   -s            Displays per-protocol statistics.  By default, statistics are                 shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;                 the -p option may be used to specify a subset of the default.   -t            Displays the current connection offload state.   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.
