       bos_addhost - Adds a database server machine to the CellServDB file


       bos addhost -server <machine name> -host <host name>+
           [-cell <cell name>] [-noauth] [-localauth] [-help]

       bos addh -s <machine name> -ho <host name>+
           [-c <cell name>] [-n] [-l] [-he]


       The bos addhost command adds an entry for each database server machine
       specified with the -host argument to the /etc/openafs/server/CellServDB
       file on the machine named by the -server argument.


       After executing this command (and waiting for the Update Server to
       propagate the changes, if it is used), restart the database server
       processes on all database server machines to force election of a quorum
       that includes the new set of machines listed in the
       /etc/openafs/server/CellServDB file. The IBM AFS Quick Beginnings
       explains in more detail how to add and remove database server machines.

       It is best to maintain a one-to-one mapping between hostnames and IP
       addresses on a multihomed database server machine (this is actually the
       conventional configuration for any AFS machine). The BOS Server uses
       the gethostbyname() routine to obtain the IP address associated with
       the hostname specified by the -host argument. If there is more than one
       address, the BOS Server records in the CellServDB entry the one that
       appears first in the list of addresses returned by the routine. The
       routine possibly returns addresses in a different order on different
       machines, which can create inconsistency.


       -server <machine name>
           Identifies the server machine on which to change the
           /etc/openafs/server/CellServDB file. Identify the machine by IP
           address or its host name (either fully-qualified or abbreviated
           unambiguously). For details, see bos(8).

           In cells that use the Update Server to distribute the contents of
           the /etc/openafs/server directory, it is conventional to specify
           only the system control machine as a value for the -server
           argument. Otherwise, repeat the command for each file server
           machine. For further discussion, see bos(8).

       -host <host name>+
           Specifies the fully-qualified host name (such as "") of
           each database server machine to register in the CellServDB file.

       -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
           are ignored.


       The following command adds the database server machines ""
       and "" to the /etc/openafs/server/CellServDB file on the
       machine "" (the system control machine).

          % bos addhost -server -host


       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
