|
|
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
|
|
Jede Zeile der Tabelle f\(:ur die Zugangskontrolle enth\(:alt drei Felder, die jeweils durch einen Doppelpunkt \(Fc:\(Fo getrennt sind:
|
|
.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\&.
|
|
.PP
|
|
Die Gruppendatei wird nur durchsucht, wenn ein Name nicht mit dem des angemeldeten Benutzers \(:ubereinstimmt\&. Eine \(:Ubereinstimmung mit Gruppen wird nur festgestellt, wenn darin der Benutzer ausdr\(:ucklich aufgef\(:uhrt ist\&. Das Programm beachtet also nicht den Wert der Hauptgruppe des Benutzers\&.
