bos_setauth - Sets authorization checking requirements for all server
bos setauth -server <machine name> -authrequired (on | off)
[-cell <cell name>] [-noauth] [-localauth] [-help]
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 bos(8).
Prints the online help for this command. All other valid options
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
KeyFile(5), NoAuth(5), UserList(5), bos(8), bos_restart(8)
