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
characters 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
delimiter, 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.
