NAME

       services - Internet services and aliases

SYNOPSIS

       /etc/inet/services

       /etc/services

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(3SOCKET) 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 number sign (#) indicates the beginning of a comment;  any  charac-
       ters that follow the comment character 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, a NEWLINE, or a comment character.

       Any changes to a port assignment do not affect the actual port registration of the service.

FILES

       /etc/nsswitch.conf      configuration file for name-service switch

SEE ALSO

       getservbyname(3SOCKET), inetd.conf(4), nsswitch.conf(4)

NOTES

       /etc/inet/services is the official SVR4 name of the services file.  The symbolic link /etc/services exists for BSD compatibility.
