protocols -- protocol name data base
The protocols file contains information regarding the known protocols
used in the DARPA Internet. For each protocol a single line should be
present with the following information:
official protocol name
protocol number
aliases
Items are separated by any number of blanks and/or tab characters. A
``#'' indicates the beginning of a comment; characters up to the end of
the line are not interpreted by routines which search the file.
Protocol names may contain any printable character other than a field
delimiter, newline, or comment character.
/etc/protocols The protocols file resides in /etc.
getprotoent(3)
A name server should be used instead of a static file.
The protocols file format appeared in 4.2BSD.
