       bos_setrestricted - place a server in restricted mode


       bos setrestricted -server <machine name> -mode 1
           [-cell <cell name>] [-noauth] [-localauth] [-help]


       The bos restricted command places the server in restricted mode. This mode increases the
       security of the bos server by removing access to a number of bos commands that are only
       used whilst configuring a system.

       When a server is in restricted mode, access to bos_exec, bos uninstall, bos install, bos
       create, bos install, bos delete, bos prune is denied, and the use of bos getlog is


       Once a server has been placed in restricted mode, it may not be opened up again using a
       remote command. That is, bos setrestricted has no method of setting an unrestricted mode.
       Once a server is restricted, it can only be opened up again by sending it a SIGFPE, which
       must be done as root on the local machine.


       -server <machine name>
           Indicates the server machine to restrict.

       -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 bos(8).

           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 are ignored.


       The issuer must be listed in the /etc/openafs/server/UserList file on the machine named by
       the -server argument, or must be logged in as the local superuser "root" if the -localauth
       flag is included.

       As noted above, this command cannot be run against servers which are already in restricted
