gapo/RPi-IP-mailer

This is to send the IP address of the Raspberry Pi to your mail ID.

RPi-IP-mailer is a shell script to send your IP address to an email account from your Raspberry Pi. It offers easy workflow when you're working with the Raspberry Pi in a headless configuration ( i.e. Just WiFi-Dongle without keyboard, mouse or monitor)

Install Dependencies

The following are dependencies.

$ sudo apt-get update
$ sudo apt-get install mailutils
$ sudo apt-get install sendmail

Check whether the command works

Run this command

$ ifconfig | mailx -s "Hello from your Raspberry Pi" yourmail@gmail.com

Replace yourmail@gmail.com with your email address. You should now recieve a mail.

Download

Easiest way would be

$ curl --remote-name https://raw.githubusercontent.com/gapo/RPi-IP-mailer/master/ip_mailer.sh
$ sudo mv ip_mailer.sh /etc/init.d/.
$ sudo chmod 700 /etc/init.d/ip_mailer.sh

Configuring /etc/hosts file

Edit your /etc/hosts file to ensure the first line is as below. If this is not set correct, sendmail does not work.

$ sudo vim /etc/hosts

Replace HOSTNAME with your hostname, The first line should be

127.0.0.1    localhost.localdomain   HOSTNAME

Adding to the Pi

NOTE: There is another way to add it by calling the script from /etc/rc.local. Both work.

Register script to be run at startup:

$ sudo update-rc.d ip_mailer.sh defaults 19

ENABLING AUTO-LOGIN (FOR HEADLESS OPERATION)

This is no longer required.

Edit the inittab file:

sudo nano /etc/inittab

Scroll down to:

1:2345:respawn:/sbin/getty 115200 tty1

and change to

#1:2345:respawn:/sbin/getty 115200 tty1

Under that line add:

1:2345:respawn:/bin/login -f pi tty1 </dev/tty1 >/dev/tty1 2>&1

Save and exit.

Removal

If you ever want to remove the script from start-up, run the following command:

$ sudo update-rc.d -f ip_mailer.sh remove 

To Do

• Figure way out to ensure it runs without login. (Is this even possible)
• Sort the dependencies. Do we really need this many.
