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 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
/etc/nsswitch.conf

configuration file for name-service switch

NOTES

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