<P>Defines AFS server encryption keys
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>KeyFile</B> file defines the server encryption keys that the AFS
|
|
server processes running on the machine use to decrypt the tickets presented
|
|
by clients during the mutual authentication process. AFS server
|
|
processes perform privileged actions only for clients that possess a ticket
|
|
encrypted with one of the keys from the file. The file must reside in
|
|
the <B>/usr/afs/etc</B> directory on every server machine. For more
|
|
detailed information on mutual authentication and server encryption keys, see
|
|
the <I>IBM AFS Administration Guide</I>.
|
|
<P>Each key has a corresponding a key version number that distinguishes it
|
|
from the other keys. The tickets that clients present are also marked
|
|
with a key version number to tell the server process which key to use to
|
|
decrypt it. The <B>KeyFile</B> file must always include a key with
|
|
the same key version number and contents as the key currently listed for the
|
|
<B>afs</B> entry in the Authentication Database.
|
|
<P>The <B>KeyFile</B> file is in binary format, so always use the
|
|
appropriate commands from the <B>bos</B> command suite to administer
|
|
it:
|
|
<UL>
|
|
<P><LI>The <B>bos addkey</B> command to define a new key
|
|
<P><LI>The <B>bos listkeys</B> command to display the keys
|
|
<P><LI>The <B>bos removekey</B> command to remove a key from the file
|
|
</UL>
|
|
<P>In cells that run the United States edition of AFS and use the Update
|
|
Server to distribute the contents of the <B>/usr/afs/etc</B> directory, it
|
|
is customary to edit only the copy of the file stored on the system control
|
|
machine. In cells that run the international version of AFS, edit the
|
|
file on each server machine individually.
