=head1 DESCRIPTION
|
|
|
|
The B<bos addhost> command adds an entry for each database server machine
|
|
specified with the B<-host> argument to the F</usr/afs/etc/CellServDB>
|
|
file on the machine named by the B<-server> argument.
|
|
|
|
=head1 CAUTIONS
|
|
|
|
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
|
|
F</usr/afs/etc/CellServDB> file. The I<OpenAFS Quick Start Guide> 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 B<-host> argument. If there is more than one
|
|
address, the BOS Server records in the F<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.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-server> <I<machine name>>
|
|
|
|
Identifies the server machine on which to change the
|
|
F</usr/afs/etc/CellServDB> file. Identify the machine by IP address or its
|
|
host name (either fully-qualified or abbreviated unambiguously). For
|
|
details, see L<bos(8)>.
|
|
|
|
In cells that use the Update Server to distribute the contents of the
|
|
F</usr/afs/etc> directory, it is conventional to specify only the system
|
|
control machine as a value for the B<-server> argument. Otherwise, repeat
|
|
the command for each file server machine. For further discussion, see
|
|
L<bos(8)>.
|
|
|
|
=item B<-host> <I<host name>>+
|
|
|
|
Specifies the fully-qualified host name (such as C<db1.abc.com>) of each
|
|
database server machine to register in the F<CellServDB> file.
|
|
|
|
=item B<-cell> <I<cell name>>
|
|
|
|
Names the cell in which to run the command. Do not combine this
|
|
argument with the B<-localauth> flag. For more details, see L<bos(8)>.
|
|
|
|
=item B<-clone>
|
|
|
|
Register the host given by B<-host> as a non-voting clone site, which
|
|
prevents the host from becoming a sync-site. This is an advanced feature
|
|
and should be used with caution.
|
|
|
|
=item B<-noauth>
|
|
|
|
Assigns the unprivileged identity C<anonymous> to the issuer. Do not combine
|
|
this flag with the B<-localauth> flag. For more details, see L<bos(8)>.
|
|
|
|
=item B<-localauth>
|
|
|
|
Constructs a server ticket using a key from the local
|
|
F</usr/afs/etc/KeyFile> file. The B<bos> command interpreter presents the
|
|
ticket to the BOS Server during mutual authentication. Do not combine this
|
|
flag with the B<-cell> or B<-noauth> options. For more details, see
|
|
L<bos(8)>.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.

|
=head1 EXAMPLES
|
|
|
|
The following command adds the database server machines C<db2.abc.com> and
|
|
C<db3.abc.com> to the F</usr/afs/etc/CellServDB> file on the machine
|
|
C<fs1.abc.com> (the system control machine).
|
|
|
|
% bos addhost -server fs1.abc.com -host db2.abc.com db3.abc.com
|
|
|
|
=head1 PRIVILEGE REQUIRED
|
|
|
|
The issuer must be listed in the F</usr/afs/etc/UserList> file on the
|
|
machine named by the B<-server> argument, or must be logged onto a server
|
|
machine as the local superuser C<root> if the B<-localauth> flag is
|
|
included.
