# pb-dydns

Script in PHP to update DNS type A records on porkbun.com using their API.

This can easily be modified to a different programming or scripting language and domain registrar.

## Prerequisites

- At least one domain in porkbun.com with DNS type A records already pointing to your dynamic IP address.
- Access to Porkbun API.

## How to use it

### from command line

```
$ php /path/to/pb-dydns.php domain_name
```

### as a cron job

```
$ crontab -e
```

Modify this line to fit your needs, and add it as many times as domains you want to automatically update:

```
*/10 * * * *    php /path/to/pb-dydns.php domain_name > /dev/null
```

That will run the script every 10 minutes.

Then restart cron (I'm not sure if this is necessary):

```
$ sudo systemctl restart cron
```

Entries to `pb-dydns.log` will be added, to view it you can:

```
$ cat /path/to/pb-dydns.log
```
