The 861744Sobrien# permissions field of that table entry determines whether the login will 961744Sobrien# be accepted or refused. 1061744Sobrien# 1127356Sjkh# Format of the login access control table is three fields separated by a 1227356Sjkh# ":" character: 131598Srgrimes# 14# permission : users : origins 15# 16# The first field should be a "+" (access granted) or "-" (access denied) 17# character. The second field should be a list of one or more login names, 18# group names, or ALL (always matches). The third field should be a list 19# of one or more tty names (for non-networked logins), host names, domain 20# names (begin with "."), host addresses, internet network numbers (end 21# with "."), ALL (always matches) or LOCAL (matches any string that does 22# not contain a "." character). If you run NIS you can use @netgroupname 23# in host or user patterns. 24# 25# The EXCEPT operator makes it possible to write very compact rules. 26# 27# The group file is searched only when a name does not match that of the 28# logged-in user. Only groups are matched in which users are explicitly 29# listed: the program does not look at a user's primary group id value. 30# 31############################################################################## 32# 33# Disallow console logins to all but a few accounts. 34# 35#-:ALL EXCEPT wheel shutdown sync:console 36# 37# Disallow non-local logins to privileged accounts (group wheel). 38# 39#-:wheel:ALL EXCEPT LOCAL .win.tue.nl 40# 41# Some accounts are not allowed to login from anywhere: 42# 43#-:wsbscaro wsbsecr wsbspac wsbsym wscosor wstaiwde:ALL 44# 45# All other accounts are allowed to login from anywhere. 46# 47
