When you don't have a static IP addres at home, but still want a DNS entry to make your home network reachable.
This script updates a DNS record at TransIP, with your current IP address.
This script uses the python REST API module for TransIP, which can be found here: https://github.com/reinoud/transip_rest_client
To get this to work, you should have the following:
- have an account at TransIP
- have an domain name at TransIP
- on the API page:
- turn API on
- generate a keypair and copy the Private Key that is shown once
- save it in a file called privatekey.txt
- convert the private key to an RSA private key (you need openssl tools installed):
openssl rsa -in privatekey.txt -out rsaprivatekey.txt
For example, when you own the example.com domain and you want to have
home.example.com point to your home server. Let's assume your TransIP
username is myusername.
Run the dyndns.py script as follows:
./dyndns.py -u myusername -k rsaprivatekey.txt -n home -d example.com
I have this script running as a cron job on my server.
When your dynamic IP address changes, it takes some time to update the DNS records. So your server should be unreachable for a little while.
Using the transip_rest_client, can be as simple as copying the following folder
to the same folder as the dyndns.py script resides:
