NETGROUP(5)		    BSD	File Formats Manual		   NETGROUP(5)

NAME
     netgroup -- defines network groups

SYNOPSIS
     netgroup

DESCRIPTION
     The netgroup file specifies "netgroups", which are	sets of	(host, user,
     domain) tuples that are to	be given similar network access.

     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 an-
     other netgroup or a specification of a tuple as follows:

	   (host, user,	domain)

     where the host, user, and domain are character string names for the cor-
     responding	component.  Any	of the comma separated fields may be empty to
     specify a "wildcard" value	or may consist of the string "-" to specify
     "no valid value".	The members of the list	may be separated by white-
     space; the	"\" character may be used at the end of	a line to specify line
     continuation.  The	functions specified in getnetgrent(3) should normally
     be	used to	access the netgroup database.

     If	`files'	is specified for the `netgroup'	database in nsswitch.conf(5),
     (or no `netgroup' entry is	specified), then these functions operate on
     the db(3) version of the netgroup (netgroup.db) file which	can be gener-
     ated using	netgroup_mkdb(8).  If `nis' is specified then the NIS maps
     `netgroup', `netgroup.byhost', and	`netgroup.byuser' are used.

     Lines that	begin with a # are treated as comments.

FILES
     /etc/netgroup.db  the netgroup database.

SEE ALSO
     getnetgrent(3), exports(5), nsswitch.conf(5), netgroup_mkdb(8)

COMPATIBILITY
     The file format is	compatible with	that of	various	vendors, however it
     appears that not all vendors use an identical format.

BUGS
     The interpretation	of access restrictions based on	the member tuples of a
     netgroup is left up to the	various	network	applications.
