<br>
The keepalive option makes sure that traffic is transmitted every N seconds. It can be used to avoid routers closing idle (keeping them "alive").<br>
<br>
If the connection is gone then the connection will be terminated after a timeout (a minute perhaps?) when the traffic is transmitted. A program doesn't get notified when a network interface goes down (at least with standard Unix programming interfaces), so it only finds out when traffic is sent.<br>
<br>
An alternative might be to "killall dropbear", "/etc/init.d/dropbear start" in /etc/ppp/ip-down.d or similar, since that part knows that the interface has gone away.<br>
<br>
Cheers,<br>

<pre class="k9mail">Hi Matt.<br /><br />Thanks for your swift reply. Could you please elaborate on what "-K" is actually meant to do (what is kept alive and how?) and how it might help me solve my problem? Documentation on Dropbear is sparse and I fail to see the connection.<br /><br />Kind regards</pre></blockquote></div></body></html>
