bos_removekey(8)

NAME
bos removekey - Removes a server encryption key from the KeyFile file

SYNOPSIS
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]

DESCRIPTION
The bos removekey command removes each specified encryption key from the /usr/afs/etc/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 version numbers.

CAUTIONS
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.

OPTIONS
Indicates the server machine on which to change the /usr/afs/etc/KeyFile file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see the bos(8) manpage.

In cells that use the Update Server to distribute the contents of the /usr/afs/etc 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 the bos(8) manpage. Specifies the key version number of each key to remove. Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see the bos(8) manpage. Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see the bos(8) manpage. Constructs a server ticket using a key from the local /usr/afs/etc/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 the bos(8) manpage. Prints the online help for this command. All other valid options are ignored.

EXAMPLES
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

PRIVILEGE REQUIRED
The issuer must be listed in the /usr/afs/etc/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 included.
