Send Email Containing IP Address On Boot

What does it do?

This code will extract the ip address of your Pi and then send an email containing the ip to the specified email address. This is inspired by the need to access the Pi via SSH or other network protocols without a monitor and moving from network to network. This assumes a Gmail SMTP server. You may need to alter a bit for other servers (beyond scope here)

What do you need?

A working, and network enabled Raspberry Pi

What skill level is required?

Medium Level. You should be comfortable navigating a linux system and be comfortable using sudo (if you want to use this script, odds are you are quite comfortable at the command prompt).

Overview of this guide

You need to

  • Create a python script and store it in a Directory
  • Make python script executable
  • Edit /boot/boot.rc

Let's Do It

Create the python script

Copy and paste the following code into a text editor (I'm a nano man myself)

import subprocess
import smtplib
import socket
from email.mime.text import MIMEText
import datetime
# Change to your own account information
to = 'me@example.com'
gmail_user = 'test@gmail.com'
gmail_password = 'yourpassword'
smtpserver = smtplib.SMTP('smtp.gmail.com', 587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo
smtpserver.login(gmail_user, gmail_password)
today = datetime.date.today()
# Very Linux Specific
arg='ip route list'
p=subprocess.Popen(arg,shell=True,stdout=subprocess.PIPE)
data = p.communicate()
split_data = data[0].split()
ipaddr = split_data[split_data.index('src')+1]
my_ip = 'Your ip is %s' %  ipaddr
msg = MIMEText(my_ip)
msg['Subject'] = 'IP For RaspberryPi on %s' % today.strftime('%b %d %Y')
msg['From'] = gmail_user
msg['To'] = to
smtpserver.sendmail(gmail_user, [to], msg.as_string())
smtpserver.quit()

Save this script using a nice name like 'startup_mailer.py' and make note of its path (like /home/pi/Code/startup_mailer.py)

For good measure, make the script executable

sudo chmod +x startup_mailer.py

Edit /boot/boot.rc

Using your text editor once again, edit /boot/boot.rc (this assumes you have already renamed this file to boot.rc If not, see RPi_Advanced_Setup). For example:

sudo nano /boot/boot.rc

Add the following at the end of the file, making changes to the path for your directory tree and save.

#Script to email ip address upon reboot
python /home/pi/Code/startup_mailer.py

Finish up

Reboot your Pi and you should receive an email with your ip address
