services - service name data base
The services 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 [alias(es)] [#comment]
Items are separated by any number of blanks, tab characters, or both. The port_number and protocol_name are considered a single item; a slash (/) is used to separate them. A pound symbol (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines that search the file.
