Type netstat -a Display all connections and listening ports, netstat -b Display the executable involved in creating each connection or listening port. In some 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. netstat -e Displays Ethernet statistics. This may be combined with the -s option. netstat -n Displays addresses and port numbers in numerical form. netstat -o Displays the owning process ID associated with each connection. netstat -p proto Shows connections for the protocol specified by proto; proto may be any of : TCP, UDP, TCPv6, or UDPv6. If used with -s option to display per-protocol statistics, proto may be any of: IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6 netstat -r Displays the routing table. netstat -s Displays per-protocol statistics. netstat -v When used in conjunction with -b, will display sequence of components involved in creating the connection or listening port for all executables.
