<section1 topic='Introduction' anchor='intro'>
|
|
<p>
|
|
When one has multiple clients at different locations logged in
|
|
simultaneously, it is often desirable to control these clients from
|
|
the client you are currently using. There are a number of common tasks
|
|
one might want to perform remotely on clients: change the status of the
|
|
client, forward all received unread messages to this client, and so on.
|
|
Therefore, it makes sense to define a protocol for performing these tasks.
|
|
</p>
|
|
|
|
<p>
|
|
This document describes a protocol to perform a set of common tasks on a
|
|
remote client, by specifying a profile of &xep0050;.
|
|
</p>
|
|
</section1>
|
|
|
|
|
|
<section1 topic='Requirements' anchor='reqs'>
|
|
<p>This document addresses the following requirements:</p>
|
|
<ul>
|
|
<li>Enable users to perform a set of common tasks on a remote
|
|
client.</li>
|
|
<li>Re-use existing XMPP and Jabber protocols wherever possible.</li>
|
|
</ul>
|
|
</section1>
|
|
|
|
|
|
<section1 topic='Discovery' anchor='disco'>
|
|
<p>A client MUST advertise any remote controlling commands it supports via
|
|
&xep0030; (as described in <strong>XEP-0050: Ad-Hoc Commands</strong>).
|
|
&xep0115; can be used to query capability of remote controlling commands
|
|
in a client.
|
|
</p>
|
|
</section1>
|
|
|
|
|
|
<section1 topic='Use Cases' anchor='usecases'>
|
|
<p>This document defines a profile of <strong>XEP-0050: Ad-Hoc Commands</strong>
|
|
that enables a user to perform the following tasks on a remote client:</p>
|
|
<ol>
|
|
<li>Change status</li>
|
|
<li>Forward unread messages residing at the remote client to the
|
|
local client</li>
|
|
<li>Change run-time options</li>
|
|
<li>Accept pending file transfer requests</li>
|
|
<li>Leave groupchats</li>
|
|
</ol>
|
|
<p>
|
|
Although this document aims to define common use cases for remote controlling clients,
|
|
an implementation or deployment MAY support any subset and MAY support additional
|
|
commands not defined herein.
|
|
</p>
|
|
<p><em>Note: The text that follows assumes that implementors have read and understood <strong>XEP-0050: Ad-Hoc Commands</strong></em>.</p>
|
|
|
|
|
|
<section2 topic='Change Status' anchor='set-status'>
|
|
<p>It is common to forget changing the status of a resource when leaving the
|
|
client for a longer period. When realizing this while at another location, it
|
|
might be desirable to change the status from there, to avoid contacts
|
|
thinking that resource is attended and sending it messages.</p>

<section2 topic='Forward Unread Messages Residing at a Remote Client' anchor='forward'>
|
|
<p>A user might want to forward all the unread messages residing at
|
|
the remote client to the local client (e.g. when the remote client was
|
|
accidentally left on-line, and has received messages in the meantime).</p>
|
|
|
|
For example, suppose Romeo sends a message to Juliet, thinking she is
|
|
still on her balcony. The balcony client receives the message:
|
|
<example caption='Remote Client Receives Message'><![CDATA[
|
|
<message from='romeo@example.com/orchard'
|
|
to='juliet@example.com/balcony'>
|
|
<subject>Just saying hi</subject>
|
|
<body>Hello Juliet!</body>
|
|
</message>
|
|
]]></example>
|
|
|
|
However, Juliet is in her chamber, so she doesn't know about the message
|
|
(yet). Realizing she left her balcony client unattended, she sends a
|
|
request to the remote client to forward all unread messages.
|
|
|
|
<example caption='Local Client Requests to Forward Unread Messages Currently Residing at the Remote Client'><![CDATA[
|
|
<iq from='juliet@example.com/chamber'

|
|
sessionid='forward:20040727T0337Z'/>
|
|
</iq>
|
|
]]></example>
|
|
|
|
The client forwards all unread messages to the local client, adding
|
|
information about the origin of the message (using the 'ofrom'
|
|
&xep0033; address, and the &xep0203; timestamp of the original message).
|
|
The chamber client receives both these messages and a
|
|
confirmation that the command was completed.

A client MAY provide a more fine-grained implementation, e.g. by
|
|
presenting the requester an extra form to select which messages
|
|
have to be forwarded.

<section2 topic='Change Run-Time Options'>
|
|
<p>It might be desirable to remotely set some run-time options of
|
|
a client. For example, when neighbours complain about the sounds your
|
|
client makes while you're at another location, you could turn the
|
|
sounds off at the remote client.

<section1 topic='Error Handling' anchor='errors'>
|
|
<p>Several error conditions are possible when an entity sends a command
|
|
request to the service, as defined in the following table. If one of these
|
|
errors occurs, the service MUST return an error stanza to the requesting
|
|
entity.</p>
|
|
|
|
<table caption='Error Conditions'>
|
|
<tr>
|
|
<th>Condition</th>
|
|
<th>Cause</th>
|
|
</tr>
|
|
<!--<tr>
|
|
<td>&conflict;</td>
|
|
<td>The command cannot be completed because of a data or system
|
|
conflict (e.g., ...)</td>
|
|
</tr>-->
|
|
<tr>
|
|
<td>&feature;</td>
|
|
<td>The specific command is not supported (even though the ad-hoc
|
|
commands protocol is)</td>
|
|
</tr>
|
|
<tr>
|
|
<td>&forbidden;</td>
|
|
<td>The requesting entity does not have sufficient privileges to
|
|
perform the command</td>
|
|
</tr>
|
|
<tr>
|
|
<td>&unavailable;</td>
|
|
<td>The ad-hoc commands protocol is not supported</td>
|

<p>For the syntax of these errors, see &xep0086;. Naturally, other errors
|
|
may be returned as well.</p>

<section1 topic='Implementation Notes' anchor='implementation'>
|
|
<p>Implementations of this protocol MAY add or remove fields to forms as
|
|
they see fit. For example, when setting the status of a remote client that
|
|
supports multiple accounts, the client may choose to add a boolean field
|
|
to allow the user to specify whether the status change should be applied
|
|
globally or only to the receiving account.</p>
|
|
|
|
<p> Implementations MAY also introduce extra forms for commands. For example,
|
|
when forwarding unread messages, a client could return a form containing a
|
|
list
|
|
of short descriptions of unread messages, allowing the user to select the
|
|
messages he wants to forward.</p>

|
|
|
<section1 topic='Security Considerations' anchor='security'>
|
|
<p>The ability to complete the tasks specified herein MUST NOT be granted
|
|
to users who lack privileges to control a client. A sensible
|
|
access policy is to only allow remote controlling by other
|
|
resources of the same account used by the client. If other accounts
|
|
are to be able to remote control the client, the client needs more
|
|
complex access right management.</p>
