bos_listhosts - Displays the configured database servers


bos listhosts -server <machine name> [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-config <configuration file>] [-help]


The bos listhosts command formats and displays the list of a cell's database server machines from the /etc/yfs/server/yfs-server.conf file on the server machine named by the -server argument.

To alter the list of machines, use the bos addhost and bos removehost commands.


-server <machine name>

Indicates the server machine from which to display the /etc/yfs/server/yfs-server.conf file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).

For consistent performance in the cell, the output must be the same on every server machine. The bos addhost reference page explains how to keep the machines synchronized.

-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/yfs/server/KeyFileExt 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).

-principal <authentication principal>

Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.

-encrypt [<yes|no>]

Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.


Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear.

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.


Prints the online help for this command. All other valid options are ignored.


The first line of the output names the cell to which the server machine belongs. Each of the following lines names a database server machine for that cell.

The Host number assigned to each database server machine is for server-internal use only and is not the same as, nor necessarily related to, the machine's IP address. The BOS Server assigned it as part of performing the bos addhost command.


The following command displays the database server machines listed in the /etc/yfs/server/yfs-server.conf file on the machine

   % bos listhosts
   Cell name is
       Host 1 is
       Host 2 is
       Host 3 is
