The +# permissions field of that table entry determines whether the login will +# be accepted or refused. +# +# Format of the login access control table is 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). A pattern of the form user@host is +# matched when the login name matches the "user" part, and when the +# "host" part matches the local machine name. +# +# 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; this +# even works for @usergroup@@hostgroup patterns. Weird. +# +# 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. +# +############################################################################## +# +# Disallow console logins to all but a few accounts. +# +#-:ALL EXCEPT wheel shutdown sync:console +# +# Disallow non-local logins to privileged accounts (group wheel). +# +#-:wheel:ALL EXCEPT LOCAL .win.tue.nl +# +# Some accounts are not allowed to login from anywhere: +# +#-:wsbscaro wsbsecr wsbspac wsbsym wscosor wstaiwde:ALL +# +# All other accounts are allowed to login from anywhere. +# |
