PROTOCOLS(4)							  PROTOCOLS(4)

NAME
     protocols - protocol name database

DESCRIPTION
     The /etc/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:

	o official protocol name

	o protocol number

	o aliases (optional)

     Items are separated by any number of blanks and/or tab characters.	 A
     ``#'' 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.	For example,

	  tcp	6    TCP     # transmission control protocol

FILES
     /etc/protocols

     If the NFS option is installed and NIS is running, the getprotoent(3N)
     library routines do not access this file.

SEE ALSO
     getprotoent(3N)

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