### Requirements
|
|
* DiG
|
|
|
|
### DNSSEC key
|
|
* need to create a dnssec key, so that we can authenticate clients' updates
|
|
```
|
|
# ddns-confgen -s myhost.example.com
|
|
```
|
|
* this key must be:
|
|
* added to DNS server's `named.conf` and associated to required zones
|
|
* stored in a text file in the same directory as the script as `dns.key`
|
|
|
|
### Install script
|
|
You may run `install.sh` (not as root, it includes `sudo`s) to:
|
|
* copy Systemd units templates to system directory
|
|
* enable timer for next reboot
|
|
* NOTE: if you move the script, you need to install again
|
|
|
|
### TODO
|
|
* review this README
|
|
|
|
### Issues
|
|

|
