* Configure the RPi to send an email to a predetermined address once its network interface is up.
However, none of them are actionable out of the box, and they require some packages to be installed on the RPi in order to work. You can however [https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=79151 push your Pi's IP to your computer/phone on boot], or note down your Pi's MAC and then scan with nmap/[https://play.google.com/store/apps/details?id=com.overlook.android.fing Fing] to find it, or even scan the subnet without your Pi connected, and then again with your Pi connected (then look at the difference between the two scans to see where your Pi is).

Assuming that you have a Zeroconf client (e.g. Avahi, Bonjour) on the machine you will use to SSH into your RPi, it would be nice to be able to use it to automatically resolve the IP address of your RPi. If both your computer and the RPi are on the same LAN (Zeroconf does not work across LANs), it would allow to use the hostname of your RPi instead of its IP address.
The problem is that there is no Zeroconf client in the default Raspbian installation, so it will have to be bootstrapped using the script above. Simply replace the "your code goes here" section line by the following:
<pre>
Basically, you have to install a DynDNS client on your RPi using the same technique as above and configure it according to the requirement of the DynDNS service you use.
As an example, using OVH's DynDNS service you can install <code>ddclient</code> on your RPi by replacing the "your code here" section line of the script above with:
<pre>

''Note: if you have not guessed it already, you have to adapt the values for ''<code>login''</code>, ''<code>password'' </code> and the domain name to match your case, and the values above are fictional.''
