NAME
       protocols - protocol name database

DESCRIPTION
       The protocols file contains information about the known protocols
       used in the networks.  Each protocol should have a one-line entry in
       the protocols file with the following information:

           official protocol name
           protocol number
           aliases (optional)
           # comment (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 that search the file.  Use only decimal
numerals to specify protocol numbers.

Names in the protocols file may contain any printable character other than a
field delimiter (blanks, tabs, CR, ESC), New Line, or comment character.

If your system is using the Network Information System (NIS), see Chapters 3
and 4 in Managing ONC (Trademark)/NFS® and Its Facilities on the DG/UX
(Trademark) System for information on how to update the protocols database.
