.Dt NETGROUP 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm netgroup
|
|
.Nd defines network groups
|
|
.Sh SYNOPSIS
|
|
.Nm netgroup
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm netgroup
|
|
file
|
|
specifies
|
|
.Dq netgroups ,
|
|
which are sets of
|
|
.Sy (host, user, domain)
|
|
tuples that are to be given similar network access.
|
|
.Pp
|
|
Each line in the file
|
|
consists of a netgroup name followed by a list of the members of the
|
|
netgroup.
|
|
Each member can be either the name of another netgroup or a specification
|
|
of a tuple as follows:
|
|
.Bd -literal -offset indent
|
|
(host, user, domain)
|
|
.Ed
|
|
.Pp
|
|
where the
|
|
.Sy host ,
|
|
.Sy user ,
|
|
and
|
|
.Sy domain
|
|
are character string names for the corresponding component.
|
|
Any of the comma separated fields may be empty to specify a
|
|
.Dq wildcard
|
|
value
|
|
or may consist of the string
|
|
.Dq Li -
|
|
to specify
|
|
.Dq no valid value .
|
|
The members of the list may be separated by whitespace;
|
|
the
|
|
.Dq \e
|
|
character may be used at the end of a line to specify
|
|
line continuation.
|
|
The functions specified in
|
|
.Xr getnetgrent 3
|
|
should normally be used to access the
|
|
.Nm netgroup
|
|
database.
|
|
.Pp
|
|
If
|
|
.Sq files
|
|
is specified for the
|
|
.Sq netgroup
|
|
database in
|
|
.Xr nsswitch.conf 5 ,
|
|
(or no
|
|
.Sq netgroup
|
|
entry is specified), then these functions operate on the
|
|
.Xr db 3
|
|
version of the
|
|
.Nm netgroup
|
|
.Nm (netgroup.db)
|
|
file which can be generated using
|
|
.Xr netgroup_mkdb 8 .
|
|
If
|
|
.Sq nis
|
|
is specified then the
|
|
.Tn NIS
|
|
maps
|
|
.Sq netgroup ,
|
|
.Sq netgroup.byhost ,
|
|
and
|
|
.Sq netgroup.byuser
|
|
are used.
|
|
.Pp
|
|
Lines that begin with a # are treated as comments.
|
|
.Sh FILES
|
|
.Bl -tag -width /etc/netgroup.db -compact
|
|
.It Pa /etc/netgroup.db
|
|
the netgroup database.

|
|
.Sh COMPATIBILITY
|
|
The file format is compatible with that of various vendors, however it
|
|
appears that not all vendors use an identical format.
|
|
.Sh BUGS
|
|
The interpretation of access restrictions based on the member tuples of a
|
|
netgroup is left up to the various network applications.
