the idea was to get my external IP and then have it delivered to me somehow.. all i could think about was to email it to my self somehow, but then i got this idea to use the script to post the IP to a text file which is located on a shared folder on Ubuntu One so every time I run the script it would get my IP address and then post it to a txt file on Ubuntu One folder that gets updated on the cloud across all connected devices and its accessible from the internet using my account. I wanted to share this simple way i thought of and maybe someone out there would find it helpful.
Requirements:-
*note that the requirements could be changed if you modified the script with your commands*
– lynx web browser which is a text based web browser. more info about it Here. It can be easily installed on Ubuntu using the following command:-
sudo apt-get install lynx
– Ubuntu One account and configured on the computer with auto sync of any folder.
That’s it really, next thing is to write or copy the following script in a text file using any text editor such as gedit and save the file with the name you like ending with .sh
#!/bin/bash
echo $(date) >> Ubuntu One/ip.txt
lynx -dump “http://www.whatismyip.com/” | grep ‘Your IP Address Is:’ >> Ubuntu One/ip.txt
after you save it make sure to give it permission to run as an executable which is easily done with a right click > properties > permissions > allow executing the file as program.
as you can see in the script.. it visits the site “whatismyip.com” then greps the line which contain “Your IP Address Is:” and then append it to ip.txt in the Ubuntu One folder along with the date and time.
the next thing would be to make the script run at start-up and enjoy knowing your external IP always from anywhere easily.
if you have any suggestions or another way or feature you might think of, please do share it with me 🙂
