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 information:
Items are separated by any number of blanks and/or tab characters. The port number and protocol name are considered a single item; a ``/'' is used to separate the port and protocol (e.g. ``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.
