Chrony - Proxmox

### Configuring Chrony on Proxmox: A Step-by-Step Guide

In the latest versions of Proxmox, Chrony is included by default, which provides an efficient and accurate network time protocol (NTP) service. This guide will walk you through the process of configuring Chrony on your Proxmox server to ensure proper time synchronization.

#### Step 1: Edit the Chrony Configuration File

To begin, you'll need to modify the Chrony configuration file. Open the configuration file with a text editor using the following command:

```bash

sudo nano /etc/chrony/chrony.conf

```

#### Step 2: Update Configuration Settings

In the configuration file, locate the section for local NTP server configuration and make the following changes:

```plaintext

# Local NTP server configuration

local stratum 8

manual

allow 192.168.1.0/24

```

- `local stratum 8` sets the stratum level for the local server.

- `manual` allows for manual configuration of time.

- `allow 192.168.1.0/24` permits NTP requests from the specified IP range.

#### Step 3: Restart and Verify Chrony Service

After updating the configuration file, restart the Chrony service to apply the changes:

```bash

sudo systemctl restart chronyd

```

To verify that Chrony is running correctly, use the following command:

```bash

sudo systemctl status chronyd

```

Check the status to ensure there are no errors and that the service is active.

#### Step 4: Verify Time Synchronization

To check the synchronization status and sources, use the Chrony commands:

```bash

chronyc tracking

chronyc sources

```

- `chronyc tracking` displays the current time synchronization status.

- `chronyc sources` lists the NTP sources that Chrony is using.

By following these steps, you’ll have Chrony configured and running on your Proxmox server, ensuring accurate time synchronization across your network.
