NAME
     services - service name data base

SYNOPSIS
     /etc/services

DESCRIPTION
     The services file contains information regarding the known
     services available in the DARPA Internet.  For each service
     a single line should be present with the following informa-
     tion:

          official service name
          port number
          protocol name
          aliases

     Items are separated by any number of blanks and/or tab char-
     acters.  The port number and protocol name are considered a
     single item; a ``/'' is used to separate the port and proto-
     col (for instance, ``512/tcp'').  A ``#'' indicates the
     beginning of a comment; characters up to the end of the line
     are not interpreted by routines which search the file.

     Service names may contain any printable character other than
     a field delimiter, newline, or comment character.

EXAMPLE
     The following is an example of an /etc/services file:

     #
     # Network services, Internet style
     #
     # $Header: $
     #
     echo      7/tcp
     echo      7/udp
     discard   9/tcp  sink null
     discard   9/udp  sink null
     systat    11/tcp users
     daytime   13/tcp
     daytime   13/udp
     netstat   15/tcp
     qotd      17/tcp quote

     telnet    23/tcp
     smtp      25/tcp mail

BUGS
     A name server should be used instead of a static file.  A
     binary indexed file format should be available for fast
     access.
