Thanks Chris,<br><br>and to everybody:<br><br><br>I can now establish a session from computer B to computer A(server), and then, from another computer, including computerA itself, shadow session on computer B. That makes no sense to me at all. I interpreted the explanation at <<a href="http://openfacts2.berlios.de/wikien/index.php/BerliosProject:FreeNX_-_HowtoShadow#An_example_nxshadowacl">http://openfacts2.berlios.de/wikien/index.php/BerliosProject:FreeNX_-_HowtoShadow#An_example_nxshadowacl</a>> thinking that you can shadow the local user, meaning the person sitting in front of the NX server, aka computer A.<br>
<br>I need to shadow the local user because of drivers and sound requirements. Here is the scenario:<br><ul><li>I need to join a webex meeting, a remote presenter (another coworker within the company) will share his desktop and establish an audio conference on the local session.<br>
</li><li>I will be sitting next to another person in the local session.<br></li><li>The audio jack of the server PC is split in 2 ports.<br></li><li>I will shadow the local session to participate in the remote presentation, the 2 PCs are next to each other, so my coworker will have a set of headphones and I will have the other, sharing the audio directly from the source, and I will get the video from the NX session</li>
<li>If I establish a session from the NX server itself, then we get no audio because the webex meeting is not linked to the local session, even when the client runs on the server itself, the meeting was started on a remote session so that it can be shadowed.<br>
</li></ul>How, then, can I shadow the local user?<br><br>THanks,<br><br><br> <b style="color: rgb(153, 153, 153);"><span style="color: rgb(153, 153, 153);"><font size="2"><font size="2"><span style="font-family: verdana,sans-serif;"><span style="font-family: trebuchet ms,sans-serif;"><span style="font-family: verdana,sans-serif;">José Pablo Méndez</span></span></span></font><br>
