bos seta-s <machine name> -a (on | off)
[-c <cell name>] [-n] [-l] [-h]
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/lib/openafs/local/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 reenable 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 "root"). Use this command instead.
-server <machine name>
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).
-authrequired (on | off)
Enables authorization checking if the value is "on", or disables it if
the value is "off".
-cell <cell name>
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, see
Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile 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
Prints the online help for this command. All other valid options are
The following example disables authorization checking on the machine
% bos setauth -server fs7.abc.com -authrequired off
The issuer must be listed in the /etc/openafs/server/UserList file on the
machine named by the -server argument, or must be logged onto a server
machine as the local superuser "root" if the -localauth flag is
