netgroup
— defines
network groups
netgroup |
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 another netgroup or a specification of a tuple as follows:
(host, user, domain)
where the
host,
user, and
domain
are character string names for the corresponding 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 whitespace; 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 generated 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.
The file format is compatible with that of various vendors, however it appears that not all vendors use an identical format.

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