bos_setauth - Sets authorization checking requirements for all server processes
bos setauth -server <machine name> -authrequired (on | off) [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-config <configuration file>] [-help]
The bos setauth command enables or disables authorization checking on the server machine named by the -server argument.
When authorization checking is enabled (the normal case),
the AFS server processes running on the machine verify that the issuer of a command meets its privilege requirements.
When authorization checking is disabled,
server processes perform any action for anyone,
including the unprivileged user
anonymous; this security exposure precludes disabling of authorization checking except during installation or emergencies.
To indicate to the server processes that authorization checking is disabled, the BOS Server creates the zero-length file /var/yfs/NoAuth on its local disk. All AFS server processes constantly monitor for the NoAuth file's presence and do not check for authorization when it is present. The BOS Server removes the file when this command is used to re-enable authorization checking.
Do not create the NoAuth file directly,
except when directed by instructions for dealing with emergencies (doing so requires being logged in as the local superuser
Use this command instead.
Indicates the server machine on which to enable or disable authorization checking. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).
Enables authorization checking if the value is
or disables it if the value is
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
Assigns the unprivileged identity
anonymous to the issuer.
Do not combine this flag with the -localauth flag.
For more details,
Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt file. The bos command interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see bos(8).
Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.
Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.
Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear.
Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.
Prints the online help for this command. All other valid options are ignored.
The following example disables authorization checking on the machine
% bos setauth -server fs7.example.com -authrequired off
The issuer must be listed in the /etc/yfs/server/UserListExt file on the machine named by the -server argument, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included.
