Name

services − service name file

Description

The services file is an ASCII file that contains information regarding the known services available in the DARPA Internet. For each service, a single line should be present with the following information:

official service name

port number

protocol name

aliases

Each service name is separated from the next by a new line. Items are separated by any number of blanks or tab characters or both.  The port number and protocol name are considered a single item; a backslash (\) is used to separate the port and protocol (for example, 512/tcp). A number sign (#) indicates the beginning of a comment; characters up to the end of the line are not interpreted by routines that search the file.

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

The services database may be distributed in a network by a naming service, such as Yellow Pages or BIND/Hesiod.  See the Guide to the Yellow Pages Service or the chapter on Hesiod in the Guide to the BIND/Hesiod Service for setup information.
