<p class="MsoNormal">I am trying to have a RasPi create a a reverse tunnel to a server so I can manage it. This should be simple enough. For some reason I have not yet been able to determine, the connection keeps dropping out. Even with autossh.<o:p></o:p></p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<p class="MsoNormal">My first problem is, what has replaced /etc/network/if-up.d/ in systemd?<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I know systemd defines things differently, but no amount of searching has given the the answer to "How to get systemd to run a script when the network is up".<o:p></o:p></p>
</div>
<p class="MsoNormal">Next is, how do I figure out *why* the connection drops? I've got autossh dumping its error messages to a log file that remains annoyingly empty, I just don't get it. I've run this same thing (autossh -f /path/cert -R 1234:here:22 foo@bar)
numerous times and it just, well, works! Only thing different in this case is that the RasPi is on a VPN that can hiccup (which the Pi detects and restarts). Thing is, with autossh, I would expect it to re-connect back to me one the Pi has finished slapping
ithe VPN around (regardless of any systemd muck).<o:p></o:p></p>

</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Internet connection to the location is also woeful, so any video chat/desktop share is fraught; or I'd use TeamViewer or something access Cygwin on a local lappy. Luckily there is an IT adept out at the location
for the next few days.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Any help gratefully received!<o:p></o:p></p>
