Gracefully Shutdown OpenVPN Server Ubuntu
If you are an OpenVPN server administrator, you might need to shut down your server at some point. It could be due to maintenance, upgrading, or other reasons. In this article, we will show you how to gracefully shut down your OpenVPN server on Ubuntu. When you shut down OpenVPN without following the correct procedure, you can end up with various issues such as connection errors, data loss, and corrupted files. So, it is essential to know the proper steps to avoid these issues.
The first step in shutting down your OpenVPN server gracefully is to stop the VPN service. You can do this by logging in to your server and using the systemctl stop openvpn command. This command stops the OpenVPN service, which disconnects all connected clients from the server. If you want to ensure that all clients have disconnected before shutting down the server, you can run the netstat -tulpn | grep openvpn command to check active connections.
After stopping the OpenVPN service, the next step is to remove the iptables rules that were created when the VPN service started. You can do this by running the iptables -D INPUT -p tcp –dport 1194 -j ACCEPT command. This command removes the rule that allows incoming connections on port 1194, which is the default OpenVPN port. If you are using a different port, you need to adjust the command accordingly.
Once you have removed the iptables rule, you can shut down the server using the shutdown -h now command. This command shuts down the server immediately. However, before running this command, make sure that all other services on your server are stopped, and there are no active users. Otherwise, you might end up losing unsaved data and causing damage to your system.
In conclusion, shutting down an OpenVPN server on Ubuntu is a simple process, but it is essential to follow the correct procedure to avoid any issues. To do this, you need to stop the VPN service, remove the iptables rule, and shut down the server using the proper command. By following these steps, you can ensure that your server shuts down gracefully without causing any harm to your system.
Step 1: Disable New Connections
| Command | Description | Example |
|---|---|---|
systemctl stop [email protected] | Stops the OpenVPN server service for the server configuration. | systemctl stop [email protected] |
iptables -I INPUT 1 -p tcp --dport port_number -j REJECT | Blocks new TCP connections on the specified port_number. | iptables -I INPUT 1 -p tcp --dport 1194 -j REJECT |
ufw deny from ip_address | Denies all incoming traffic from the specified ip_address. | ufw deny from 192.168.0.2 |
If you have a firewall installed, you may need to add rules to block incoming traffic on the OpenVPN port. This will prevent new connections from being established while you shut down the server. You can use the following command to block incoming TCP traffic on the OpenVPN port: |
|
Step 2: Wait for Connected Clients to Disconnect
| Client IP Address | Connected Since | Status |
|---|---|---|
| 192.168.1.100 | 10:00 AM | Active |
| 192.168.1.101 | 10:15 AM | Active |
| 192.168.1.102 | 10:30 AM | Active |
| 192.168.1.103 | 10:45 AM | Idle |
| 192.168.1.104 | 11:00 AM | Idle |
After you have disconnected from the remote server, you need to wait for any connected clients to disconnect as well. This is an important step, as abruptly closing the connection while clients are still connected can lead to data corruption or loss.
Make sure to keep an eye on the connected clients table for any active or idle connections. An idle connection means that the client is still connected, but there has been no activity for a certain period of time.
Once all clients have disconnected, you can safely shut down the server without any risk of data loss or corruption.
Step 3: Stop OpenVPN Service
Once all connected clients have disconnected, the next step is to stop the OpenVPN service. This can be done using the appropriate command for your operating system. On Linux, for example, you can use the command systemctl stop openvpn to stop the service.
It’s important to properly stop the OpenVPN service to ensure that all data has been written to disk and that there are no lingering processes or connections. This will prevent any data corruption or loss when the server is shut down.
After the OpenVPN service has been stopped, you can proceed to shut down the server. This can be done using the appropriate command for your operating system. On Linux, you can use the command shutdown -h now to initiate a shutdown immediately.
