TCP and UDP Ports and Services B
Table B-1 lists common port numbers—well-known ports—assigned to TCP and UDP
services—well-known services—by the Internet Assigned Network Numbers
Authority (IANA). A more complete list is available in RFC 1700, Assigned Numbers.
Note – If you are configuring a filter on a PortMaster from the command line interface,
you must use the port number. The PortMaster does not have the /etc/services file and
cannot use NIS to get the equivalent information.
