NAME

services − Internet services and aliases

DESCRIPTION

The services file is a local source of information regarding each service available through the Internet.  The services file can be used in conjunction with or instead of other services sources, including the NIS maps “services.byname” and the NIS+ table “services”.  Programs use the getservbyname(3N) routines to access this information. 

The services file contains an entry for each service.  Each entry has the form:

service-name   port/protocol   aliases

service-name This is the official Internet service name. 

port/protocol This field is composed of the port number and protocol through which the service is provided (for instance, 512/tcp). 

aliases This is a list of alternate names by which the service might be requested. 

Fields can be separated by any number of SPACE and/or TAB characters.  A ‘#’ (pound-sign) 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.
