bos_removekey - Removes a server encryption key from the KeyFile file
bos removekey -server <machine name>
-kvno <key version number>+ [-cell <cell name>]
[-noauth] [-localauth] [-help]
bos removek -s <machine name> -k <key version number>+
[-c <cell name>] [-n] [-l] [-h]
The bos removekey command removes each specified encryption key from
the /etc/openafs/server/KeyFile file on the machine named by the
-server argument. Use the -kvno argument to identify each key by its
key version number; use the bos listkeys command to display the key
Before removing a obsolete key, verify that the cell’s maximum ticket
lifetime has passed since the current key was defined using the kas
setpassword and bos addkey commands. This ensures that no clients still
possess tickets encrypted with the obsolete key.
-server <machine name>
Indicates the server machine on which to change the
/etc/openafs/server/KeyFile 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).
-kvno <key version number>+
Specifies the key version number of each key to remove.
-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
The following command removes the keys with key version numbers 5 and 6
from the KeyFile file on the system control machine "fs1.abc.com".
% bos removekey -server fs1.abc.com -kvno 5 6
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
