The +permissions field of that table entry determines whether the login will +be accepted or refused. +.Pp +Each line of the login access control table has three fields separated by a +":" character: permission : users : origins + +The first field should be a "+" (access granted) or "-" (access denied) +character. The second field should be a list of one or more login names, +group names, or ALL (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 "."), ALL (always matches) or LOCAL (matches any string that does +not contain a "." character). If you run NIS you can use @netgroupname +in host or user patterns. + +The EXCEPT operator makes it possible to write very compact rules. + +The group file is searched only when a name does not match that of the +logged-in user. Only groups are matched in which users are explicitly +listed: the program does not look at a user's primary group id value. +.Sh FILES +.Bl -tag -width /etc/login.access -compact +.It Pa /etc/login.access +The +.Nm login.access +file resides in +.Pa /etc . +.El +.Sh SEE ALSO +.Xr login 1 +.Sh AUTHOR +Guido van Rooij |
