NAME
     services - Internet services and aliases

SYNOPSIS
     /etc/inet/services

     /etc/services

DESCRIPTION
     The services file  is a local source of information  regard-
     ing  each  service  available through the Internet. The ser-
     vices 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
