PROTOCOLS(5)              OpenBSD Programmer's Manual             PROTOCOLS(5)

NAME
     protocols - protocol name database

DESCRIPTION
     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 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)

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.

HISTORY
     The protocols file format appeared in 4.2BSD.

OpenBSD 3.0                      June 5, 1993                                1
