GOAL:
What are TCP/IP ports?
GOAL:
What are privileged ports?
GOAL:
What are unprivileged ports?
FIX:
Ports are a means of identifying and separating network based services. There are 65536 ports.
Port numbers 0 through 1023 are called privileged ports, and for UNIX require root privileges to open. This is different than connecting to the port. This is why any server listening on these ports must have root access at some point.
Ports 1024 through 6555 are generally used for the client side of the connection and do not require root privileges to open. They are therefore, generally known as unprivileged ports. It is possible. however, to run servers on these ports.
