NAME

protocols — protocol name data base

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 (“#”) 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.

FILES

/etc/protocols

The protocols file resides in /etc.

SEE ALSO

HISTORY

The protocols file format appeared in 4.2BSD.

BUGS

A name server should be used instead of a static file.
