# NTP Server

Your node can serve as NTP server. 

## Client Access Restrictions
To allow access you need to configure which networks/hosts are allowed to contact `chrony` in the Hiera list `ntp_server::allow`:

```
ntp_server::allow:
  - '129.129.0.0/16'
  - '10.10.10.10'
```

## Management Access for Unprivileged Users

A user which belongs to the group `chrony` is allowed to control the NTP server with `chronyc`.
