This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
netcat (often abbreviated to nc) is a computer networking utility for reading from and writing to network connections using TCP or UDP.The command is designed to be a dependable back-end that can be used directly or easily driven by other programs and scripts.
If the port is not yet established, the port number is shown as an asterisk. Foreign Address – The IP address and port number of the remote computer to which the socket is connected. The names that corresponds to the IP address and the port are shown unless the -n parameter is specified. If the port is not yet established, the port number is ...
If a normal Nmap-portscan is used the ports will be said to be open, but this does not necessarily mean there is an open proxy. Nmap can, however, check via its scripts http-open-proxy and socks-open-proxy. An example would be: nmap -P0 --script=socks-open-proxy --script=http-open-proxy.nse -p<ports to check> <host> Or is it another type of ...
For TCP, port number 0 is reserved and cannot be used, while for UDP, the source port is optional and a value of zero means no port. A process associates its input or output channels via an internet socket , which is a type of file descriptor , associated with a transport protocol , a network address such as an IP address , and a port number.
The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.

The end user would choose Community ports or both Open and Community ports. If the end user chooses Community ports only, the end user could then decide to allow all IP's from foreign countries or just the IP's from compliant countries or no foreign IP's, all of this configuration would happen at the ISP level.
