+## Client side configuration
+You should run the client side ssh command in a loop because it is tuned to terminate as soon as errors are detected. Don't worry, this is well tested. If you are old school you simply put this into `/etc/rc.local`:
+
+```
+#!/bin/bash
+
+(while true; do
+        ssh ...
+        sleep 30
+done) &
+disown
+
+exit 0
+```
+Don't forget to mark the script as executable: `chmod +x /etc/rc.local`
