NAME
services —
service name data base
DESCRIPTION
Theservices file contains information regarding the
known services available in the Internet. For each service a single line
should be present with the following information:
official service name port number protocol name aliases
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; subsequent characters up to the end of the line are not interpreted by the routines which search the file.
Service names may contain any printable character other than a field delimiter, newline, or comment character.
NIS INTERACTION
Access to the NIS services.byname map can be enabled by adding a single ``+'' on a line by itself in the /etc/services file. This causes the contents of the NIS services map to be inserted at the location where the ``+'' appears.
FILES
- /etc/services
- The
servicesfile resides in /etc.

HISTORY

BUGS
