title: DDNS Using Njalla
|
|
---
|
|
|
|
Go to your domain on njalla:
|
|
|
|
|
|
|
|
Then press "Add record" and select "Dynamic" and write your subdomain in
|
|
the input box. It should now be added to your records. Click on the record,
|
|
you should now see something like the following:
|
|
|
|
|
|
|
|
With this, then your JSON file should contain:
|
|
|
|
```json
|
|
{
|
|
"jellyfin.example.com": "48esqclnvqGiCZPbd"
|
|
}
|
|
```
|
|
|
|
Add this as a secret file to your secrets (See [this page](/wiki/secrets)
|
|
for secrets management). This could be done, for example, in the following way:
|
|
|
|
- Writing the specified JSON to `/data/.secret/njalla/keys-file.json`
|
|
- Setting the owner as root:
|
|
- `sudo chown root:root /data/.secret/njalla/keys-file.json`
|
|
- Setting the permissions to 700 (read, write, execute for file owner, root):
|
|
- `sudo chmod 700 /data/.secret/njalla/keys-file.json`
|
|
|
|
And finally adding it to your nix configuration:
|
|
|
|
```nix
|
|
nixarr.ddns.njalla = {
|
|
enable = true;
|
|
keysFile = "/data/.secret/njalla/keys-file.json";
|
|
};
|
|
```
|
|
|
|
After rebuilding, you can check the output of the DDNS script:
|
|
|
|
```sh
|
|
sudo systemctl status ddnsNjalla.service
|
|
```
|
|
|
|
Where you should see something like:
|
|
|
|
```
|
|
Mar 03 21:05:00 pi systemd[1]: Starting Sets the Njalla DDNS records...
|
|
Mar 03 21:05:02 pi ddns-njalla[26842]: {"status": 200, "message": "record updated", "value": {"A": "93.184.216.34"}}
|
|
Mar 03 21:05:02 pi ddns-njalla[26845]: {"status": 200, "message": "record updated", "value": {"A": "93.184.216.34"}}
|
|
Mar 03 21:05:02 pi systemd[1]: ddnsNjalla.service: Deactivated successfully.
|
|
Mar 03 21:05:02 pi systemd[1]: Finished Sets the Njalla DDNS records.
|
|
Mar 03 21:05:02 pi systemd[1]: ddnsNjalla.service: Consumed 560ms CPU time, received 11.7K IP traffic, sent 3.0K IP traffic.
|
|
```
|
|
|
|
Then run the following to get your public IP address:
|
|
|
|
```sh
|
|
curl https://ipv4.icanhazip.com/
|
|
```
|
|
|
|
And if you check your njalla domain page, you should see your public IP on
|
|
your Dynamic DNS record!
|
|
|
|
And after waiting a little you should be able to connect to your ip, using
|
|
the set domain.
