bos_addkey - Adds a new server encryption key to the KeyFile file
bos addkey -server <machine name> [-key <key>]
-kvno <key version number> [-cell <cell name>]
[-noauth] [-localauth] [-help]
bos addk -s <machine name> [-ke <key>]
-kv <key version number> [-ce <cell name>] [-n]
The bos addkey command constructs a server encryption key from the text
string provided, assigns it the key version number specified with the
-kvno argument, and adds it to the /etc/openafs/server/KeyFile file on
the machine specified with the -server argument. Be sure to use the kas
setpassword or kas setkey command to add the same key to the "afs"
entry in the Authentication Database.
Do not use the -key argument, which echoes the password string visibly
on the screen. If the argument is omitted, the BOS Server prompts for
the string and does not echo it visibly:
Retype input key:
The BOS Server prohibits reuse of any key version number already listed
in the /etc/openafs/server/KeyFile file. This ensures that users who
still have tickets sealed with the current key are not prevented from
communicating with a server process because the current key is
overwritten with a new key. Use the bos listkeys command to display the
key version numbers in the /etc/openafs/server/KeyFile file.
-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).
Specifies a character string just like a password; the BOS Server
calls a DES conversion function to encode it into a form
appropriate for use as an encryption key. Omit this argument to
have the BOS Server prompt for the string instead.
-kvno <key version number>
Defines the new key’s key version number. It must be an integer in
the range from 0 (zero) through 255. For the sake of simplicity,
use the number one higher than the current highest key version
number; use the bos listkeys command to display key version
-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
If the strings typed at the "Input key" and "Retype input key" prompts
do not match, the following message appears, and the command exits
without adding a new key:
Input key mismatch
The following command adds a new server encryption key with key version
number 14 to the KeyFile file kept on the machine "fs1.abc.com" (the
system control machine). The issuer omits the -key argument, as
recommended, and provides the password at the prompts.
% bos addkey -server fs1.abc.com -kvno 14
Retype input key:
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
