<p class="MsoNormal"><span>Thanks for the reply.<u></u><u></u></span></p>
<p class="MsoNormal"><span>My use case is that syslog-ng is running in one namespace but I wanted to send the logs to the remote server which is reachable in another namespace.<u></u><u></u></span></p>
<p class="MsoNormal"><span>Can we specify the outgoing namespace in destination network() in syslog-ng configuration.<u></u><u></u></span></p>

<p class="MsoNormal">Sorry if I misunderstood your question.<br>
Do you mean does syslog-ng use Linux namespaces?<br>

</div>
<p class="MsoNormal" style="margin-bottom:12pt">AFAIK it does not.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">If you mean that a remote host(e.g. server) has network namespaces, I think that should work, as that's transparent to a different host (e.g. client).<u></u><u></u></p>

<p class="MsoNormal">Can you elaborate your use case, please?<u></u><u></u></p>
