|
|
<P>This command does not use the syntax conventions of the AFS command
|
||
|
|
suites. Provide the command name and all option names in full.
|
||
|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>upserver</B> command initializes the server portion of the
|
||
|
|
Update Server (the <B>upserver</B> process). In the conventional
|
||
|
|
configuration, its binary file is located in the <B>/usr/afs/bin</B>
|
||
|
|
directory on a file server machine.
|
||
|
|
<P>The <B>upserver</B> command is not normally issued at the command shell
|
||
|
|
prompt but rather placed into a file server machine's
|
||
|
|
<B>/usr/afs/local/BosConfig</B> file with the <B>bos create</B>
|
||
|
|
command. If it is ever issued at the command shell prompt, the issuer
|
||
|
|
must be logged onto a database server machine as the local superuser
|
||
|
|
<B>root</B>.
|
||
|
|
<P>The <B>upserver</B> command specifies which of the directories on the
|
||
|
|
local disk are eligible for distribution in response to requests from the
|
||
|
|
client portion of the Update Server (the <B>upclient</B> process) running
|
||
|
|
on other machines. If no directories are specified, the
|
||
|
|
<B>upserver</B> process distributes the contents of any directory on its
|
||
|
|
local disk.
|
||
|
|
<P>The <B>upserver</B> process can distribute a directory's contents
|
||
|
|
in encrypted or unencrypted form. By default, it does not use
|
||
|
|
encryption unless an <B>upclient</B> process requests it (this default is
|
||
|
|
equivalent to setting the <B>-clear</B> flag). When the
|
||
|
|
<B>-crypt</B> flag is provided, the <B>upserver</B> process only
|
||
|
|
fulfills requests for encrypted transfer.
|
||
|
|
<P>For the United States edition of AFS, using the <B>-crypt</B> flag
|
||
|
|
guarantees that the <B>upserver</B> process transfers a directory's
|
||
|
|
contents only in encrypted form. For the international edition, using
|
||
|
|
the <B>-crypt</B> flag completely blocks data transfer, because the
|
||
|
|
international edition of the <B>upclient</B> process cannot request
|
||
|
|
encrypted transfer (the <B>upclient</B> initialization command does not
|
||
|
|
include the <B>-crypt</B> flag).
|
||
|
|
<P>The <B>upclient</B> and <B>upserver</B> processes always mutually
|
||
|
|
authenticate, whether or not the data they pass is encrypted; they use
|
||
|
|
the key with the highest key version number in the
|
||
|
|
<B>/usr/afs/etc/KeyFile</B> file to construct a server ticket for mutual
|
||
|
|
authentication.
|
||
|
|
<P><STRONG>Cautions</STRONG>
|
||
|
|
<P>Do not use the Update Server to distribute the contents of the
|
||
|
|
<B>/usr/afs/etc</B> directory if using the international edition of
|
||
|
|
AFS. The contents of this directory are sensitive and the international
|
||
|
|
edition of AFS does not include the encryption routines necessary for
|
||
|
|
encrypting files before transfer across the network.
|
||
|
|
<P><STRONG>Options</STRONG>
|
||
|
|
<DL>
|
||
|
|
<P><DT><B><VAR>directory</VAR>
|
||
|
|
</B><DD>Names each directory to distribute in unencrypted form (because they
|
||
|
|
appear before the first <B>-crypt</B> or <B>-clear</B> flag on the
|
||
|
|
command line). If this argument is omitted, all directories on the
|
||
|
|
machine's local disk are eligible for distribution.
|
||
|
|
<P><DT><B>-crypt
|
||
|
|
</B><DD>Precedes a list of one or more directories that the <B>upserver</B>
|

|

|
|
<P><DT><B>-clear
|
||
|
|
</B><DD>Precedes a list of one or more directories that the <B>upserver</B>
|
||
|
|
process distributes in unencrypted form unless the <B>upclient</B> process
|
||
|
|
requests them in encrypted form. Use this argument only if a list of
|
||
|
|
directories headed by the <B>-crypt</B> flag precedes it on the command
|
||
|
|
line.
|
||
|
|
<P><DT><B>-auth
|
||
|
|
</B><DD>Precedes a list of one or more directories which the <B>upserver</B>
|

process distributes using a form of encryption that is intermediate in
|
||
|
|
complexity and security between the unencrypted and encrypted levels set by
|
||
|
|
the <B>-clear</B> and <B>-crypt</B> arguments. Do not use this
|
||
|
|
argument, because the <B>upclient</B> process does not have a
|
||
|
|
corresponding argument that it can use to request data transfer at this
|
||
|
|
level.
|
||
|
|
<P><DT><B>-help
|
||
|
|
</B><DD>Prints the online help for this command. All other valid options
|

are ignored.

|
|
</DL>
|
||
|
|
<P><STRONG>Examples</STRONG>
|
||
|
|
<P>The following example <B>bos create</B> command defines and starts an
|
||
|
|
<B>upserver</B> process on the host machine
|
||
|
|
<B>fs1.abc.com</B>. The last parameter (enclosed in
|
||
|
|
quotes) instructs the <B>upserver</B> process to distribute the contents
|
||
|
|
of the <B>/usr/afs/bin</B> directory in unencrypted form and the contents
|
||
|
|
of the <B>/usr/afs/etc</B> directory in encrypted form.
|
||
|
|
<PRE> % <B>bos create -server fs1.abc.com -instance upserver -type simple</B> \
|
||
|
|
<B>-cmd "/usr/afs/bin/upserver /usr/afs/bin -crypt /usr/afs/etc"</B>
|
||
|
|
</PRE>
|
||
|
|
<P><STRONG>Privilege Required</STRONG>
|
||
|
|
<P>The issuer must be logged in as the superuser <B>root</B> on a file
|
||
|
|
server machine to issue the command at a command shell prompt. It is
|
||
|
|
conventional instead to create and start the process by issuing the <B>bos
|
||
|
|
create</B> command.
