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 map "services.byname". 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
characters 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
