37.Os
38.Sh NAME
39.Nm services
40.Nd service name data base
41.Sh DESCRIPTION
42The
43.Nm
44file contains information regarding
45the known services available in the
46Internet.
47For each service a single line should be present
48with the following information:
49.Bd -unfilled -offset indent
50official service name
51port number
52protocol name
53aliases
54.Ed
55.Pp
56Items are separated by any number of blanks and/or tab characters.
57The port number and protocol name are considered a single
58.Em item ;
59a ``/'' is used to
60separate the port and protocol (e.g.\& ``512/tcp'').
61A ``#'' indicates the beginning of
62a comment; subsequent characters up to the end of the line are
63not interpreted by the routines which search the file.
64.Pp
65Service names may contain any printable
66character other than a field delimiter, newline,
67or comment character.
68.Sh NIS INTERACTION
69Access to the NIS
70.Pa services.byname
71map can be enabled by adding a single ``+'' on a line by itself
72in the
73.Pa /etc/services
74file.
75This causes the contents of the NIS services map to be inserted
76at the location where the ``+'' appears.
77.Sh FILES
78.Bl -tag -width /etc/services -compact
79.It Pa /etc/services
