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
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.
