PROTOCOLS(4)                                         PROTOCOLS(4)



     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 ``#'' 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
