Update your public ip information in a git repository.
How to use
- Create a GitHub repository
- Clone it locally
cdinto that directory
- If it works, you should see some IP information in the GitHub repository.
- Run automatically as a cron job (e.g. every hour).
When traveling, I do not have access to my home computer. It is a powerful machine with a fast internet connection.
Also, I do not have a static public ip assigned to that network. The machine does get a static ip from the router. The router does port forwarding on a specific range.
SSH is running on it and it listens on a specific port, exposed in the router.
Whereever I am, I can now
ssh to my home computer and do tasks that require more performance (e.g. AI training etc).
Just in case the public ip is going to change, I will see it in my GitHub repository.
Getting a static ip from the router
For posterity, this is my
auto lo iface lo inet loopback auto enp5s0 iface enp5s0 inet static address 192.168.2.xxx netmask 255.255.255.0 gateway 192.168.2.1 dns-nameservers 18.104.22.168 192.168.1.1
## Listening for ssh connections In `/etc/ssh/sshd_config`, change the `Port` value to whatever value you want
**Do use SSH keys for authentication, instead of passwords.** ## Connecting ```sh ssh -A <username>@<public-ip> -p <port>
I added the cron job by running
crontab -e and writing in that file:
SHELL=/bin/sh PATH=/home/testing/.nvm/versions/node/v6.7.0/bin:/home/testing/bin:/home/testing/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bi # Min Hour Day Month Weekday Command */10 * * * * /johnnysapps/ip
/johnnysapps/ip script contains. This is executed every 10 minutes. In case the electricity goes down, I assume the laptop battery will resist for an hour or so until the electricity is back.
echo "Adding the ssh key" ssh-add /home/testing/.ssh/id_rsa echo "Changing directory" cd /johnnysapps/notebook ls echo "Getting the ip" date > last_updated.txt machine-ip
You can install the package globally and use it as command line tool:
# Using npm npm install --global machine-ip # Using yarn yarn global add machine-ip
machine-ip --help and see what the CLI tool can do.
$ machine-ip --help Usage: machine-ip [options] Update your public ip information in a git repository. Options: -v, --version Displays version information. -h, --help Displays this help. Documentation can be found at https://github.com/IonicaBizau/machine-ip#readme.

💖 Support my projects
I open-source almost everything I can, and I try to reply everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).
However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:
