backup_addhost - Adds a Tape Coordinator entry to the Backup Database


backup addhost -tapehost <tape machine name> [-portoffset <TC port offset>] [-localauth] [-butc_noauth] [-cell <cell name>] [-config <configuration file>] [-help]


The backup addhost command creates a Tape Coordinator entry in the Backup Database. The entry records

Each Tape Coordinator must have its own port offset number, and the command fails if a Backup Database entry already exists for the requested port offset number. To display existing Tape Coordinator entries, use the backup listhosts command.


-tapehost <tape machine name>

Specifies the fully-qualified hostname of the machine for which to create a Tape Coordinator entry in the Backup Database. The machine must have an entry in either the cell's naming service (such as the Domain Name Service) or the host file (/etc/hosts or equivalent) on the machine where the command is issued.

-portoffset <TC port offset>

Specifies the Tape Coordinator's port offset number. Provide an integer from the range 0 through 58510, or omit this argument to use the default value of 0 (zero). The value must match the port offset number recorded for the same combination of Tape Coordinator and tape device or file in the /Library/Auristor/Tools/var/yfs/backup/tapeconfig file on the Tape Coordinator machine named by the -tapehost argument.


Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt file. The backup command interpreter presents it to the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more details, see backup(8).


Assigns the unprivileged identity anonymous to the issuer for all connections to Tape Controllers butc. This option should only be used when the Tape Controller is incapable of authenticated connections.

-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 backup(8).

-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 creates an entry in the Backup Database that assigns port offset number 4 to a Tape Coordinator running on the machine

   % backup addhost -tapehost -portoffset 4

The following command creates a Backup Database entry that assigns port offset number 0 to a Tape Coordinator on the machine

   % backup addhost


The issuer must be listed in the /etc/yfs/server/UserListExt file on every machine where the Backup Server is running, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included. =head1 SEE ALSO
