Dependencies on port numbers

You must note the following when selecting the port number:

• Port numbers lower than IPPORT_RESERVED (1024) are reserved for privileged users.

• Port numbers in the range from 1024 to PRIVPORT# must differ from port numbers with fixed assignments for privileged applications (see "Dependencies on the BS2000 transport system BCAM").

• Certain port numbers are reserved for some standard applications. These worldwide applicable assignments are stored in the /etc/inet/services file. For local networks, this file can be extended to specify assigned port numbers.
