.SH "DESCRIPTION"
.PP
The
\fIlogin\&.access\fR
file specifies (user, host) combinations and/or (user, tty) combinations for which a login will be either accepted or refused\&.
.PP
When someone logs in, the
\fIlogin\&.access\fR
is scanned for the first entry that matches the (user, host) combination, or, in case of non\-networked logins, the first entry that matches the (user, tty) combination\&. The permissions field of that table entry determines whether the login will be accepted or refused\&.
.PP
Chaque ligne de la table de contr\(^ole des connexions (\(Fo\ \&login access control table\ \&\(Fc) est compos\('ee de trois champs s\('epar\('es par le caract\(`ere \(Fo\ \&:\ \&\(Fc\ \&:
.PP
\fIpermission\fR:\fIusers\fR:\fIorigins\fR
.PP
The first field should be a "\fI+\fR" (access granted) or "\fI\-\fR" (access denied) character\&. The second field should be a list of one or more login names, group names, or
\fIALL\fR
(always matches)\&. The third field should be a list of one or more tty names (for non\-networked logins), host names, domain names (begin with "\&."), host addresses, internet network numbers (end with "\&."),
\fIALL\fR
(always matches) or
\fILOCAL\fR
(matches any string that does not contain a "\&." character)\&. If you run NIS you can use @netgroupname in host or user patterns\&.
.PP
The
\fIEXCEPT\fR
operator makes it possible to write very compact rules\&.
