</PRE>
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>bos listkeys</B> command formats and displays the list of server
|
|
encryption keys from the <B>/usr/afs/etc/KeyFile</B> file on the server
|
|
machine named by the <B>-server</B> argument.
|
|
<P>To edit the list of keys, use the <B>bos addkey</B> and <B>bos
|
|
removekey</B> commands.
|
|
<P><STRONG>Cautions</STRONG>
|
|
<P>Displaying actual keys on the standard output stream (by including the
|
|
<B>-showkey</B> flag) is a security exposure. Displaying a checksum
|
|
is sufficient for most purposes.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B><B>-server</B>
|
|
</B><DD>Indicates the server machine from which to display the <B>KeyFile</B>
|
|
file. Identify the machine by IP address or its host name (either
|
|
fully-qualified or abbreviated unambiguously). For details, see the
|
|
introductory reference page for the <B>bos</B> command suite.
|
|
<P>For consistent performance in the cell, the output must be the same on
|
|
every server machine. The <B>bos addkey</B> reference page explains
|
|
how to keep the machines synchronized.
|
|
<P><DT><B><B>-showkey</B>
|
|
</B><DD>Displays the octal digits that constitute each key.
|
|
<P><DT><B><B>-cell</B>
|
|
</B><DD>Names the cell in which to run the command. Do not combine this
|
|
argument with the <B>-localauth</B> flag. For more details, see the
|
|
introductory <B>bos</B> reference page.
|
|
<P><DT><B><B>-noauth</B>
|
|
</B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
|
|
issuer. Do not combine this flag with the <B>-localauth</B>
|
|
flag. For more details, see the introductory <B>bos</B> reference
|
|
page.
|
|
<P><DT><B><B>-localauth</B>
|
|
</B><DD>Constructs a server ticket using a key from the local
|
|
<B>/usr/afs/etc/KeyFile</B> file. The <B>bos</B> command
|
|
interpreter presents the ticket to the BOS Server during mutual
|
|
authentication. Do not combine this flag with the <B>-cell</B> or
|
|
<B>-noauth</B> options. For more details, see the introductory
|
|
<B>bos</B> reference page.
|
|
<P><DT><B>-help
|
|
</B><DD>Prints the online help for this command. All other valid options
|
|
are ignored.
|
|
</DL>
|
|
<P><STRONG>Output</STRONG>
|
|
<P>The output includes one line for each server encryption key listed in the
|
|
<B>KeyFile</B> file, identified by its key version number.
|
|
<P>If the <B>-showkey</B> flag is included, the output displays the actual
|
|
string of eight octal numbers that constitute the key. Each octal
|
|
number is a backslash and three decimal digits.
|
|
<P>If the <B>-showkey</B> flag is not included, the output represents each
|
|
key as a checksum, which is a decimal number derived by encrypting a constant
|
|
with the key.
|
|
<P>Following the list of keys or checksums, the string <TT>Keys last
|
|
changed</TT> indicates when a key was last added to the <B>KeyFile</B>
|
|
file. The words <TT>All done</TT> indicate the end of the
|
|
output.
|
|
<P>For mutual authentication to work properly, the output from the command
|
|
<B>kas examine afs</B> must match the key or checksum with the same key
|
|
version number in the output from this command.
|
|
<P><STRONG>Examples</STRONG>
|
|
<P>The following example shows the checksums for the keys stored in the
|
|
<B>KeyFile</B> file on the machine
|
|
<B>fs3.abc.com</B>.
|
|
<PRE> % <B>bos listkeys fs3.abc.com</B>

<P><STRONG>Privilege Required</STRONG>
|
|
<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on

the machine named by the <B>-server</B> argument, or must be logged onto a

server machine as the local superuser <B>root</B> if the
