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\&. .SH "DATEIEN" .PP /etc/login\&.defs .RS 4 Konfiguration der Shadow\-Passwort\-Werkzeugsammlung .RE .SH "SIEHE AUCH" .PP \fBlogin\fR(1)\&.
