bos_setcellname - Sets the cell's name in ThisCell and CellServDB [DEPRECATED]


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


The bos setcellname command establishes the cell's name and makes the server machine named by the -server argument a member of it, by recording the value of the -name argument in two files which it creates on the local disk:


Issue this command only when the installing the cell's first AFS server machine. The OpenAFS Quick Start Guide explains how to copy over the ThisCell and CellServDB files from this or another appropriate machine during installation of additional server machines.

Be sure to choose a satisfactory cell name when issuing this command, because changing a cell's name is very complicated. Consult the OpenAFS Administration Guide for advice on choosing a cell name.


-server <machine name>

Indicates the server machine on which to set the cell name in the ThisCell and CellServDB file. It is always the first machine installed in a cell. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).

-name <cell name>

Defines the cell name, using standard Internet domain name format (the actual domain name is usually appropriate). Examples are for the Example Corporation and for the Example Organization. It must match the value of the -cell argument, if that is provided.

-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 following command defines the cell name in the ThisCell and CellServDB files on the machine as it is installed as the cell's first server machine.

   % bos setcellname -server -name


Authorization checking is normally turned off during installation, which is the only recommended time to use this command; in this case no privilege is required. If authorization checking is turned on, the issuer must be listed in the /etc/yfs/server/UserListExt 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.


This command is not supported by the AuriStor bosserver. It is provided for use with IBM AFS 3.6 and OpenAFS servers.
