PROTOCOLS(5)		  FreeBSD File Formats Manual		  PROTOCOLS(5)

NAME
     protocols -- protocol name	database

DESCRIPTION
     The protocols file	contains information regarding the known protocols
     used in the 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 hash mark (`#') indicates the beginning of a comment; subsequent	char-
     acters up to the end of the line are not interpreted by the routines
     which search the file.

     Protocol names may	contain	any printable character	other than a field de-
     limiter, newline, or comment character.

FILES
     /etc/protocols

SEE ALSO
     getprotoent(3)

HISTORY
     The protocols file	format appeared	in 4.2BSD.

BUGS
     A name server should be used instead of a static file.  Lines in
     /etc/protocols are	limited	to BUFSIZ characters (currently	1024).	Longer
     lines will	be ignored.
