SERVICES(5N) COMMAND REFERENCE SERVICES(5N) NAME services - service name data base DESCRIPTION The services file contains information regarding the known services available on the local network. 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; 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.

The nameserver(8N) does not provide this information since it is not machine specific. SEE ALSO getservent(3N). Printed 5/12/88 3
