Configure UFW Firewall for Cockpit on Ubuntu 22.04
This section of the guide walks you through setting up the Uncomplicated Firewall (UFW) to permit access to the Cockpit. As port 9090 is where Cockpit listens by default, you need to make sure that the firewall rules permit incoming connections on this port.
Step 1: Check UFW Status
It is imperative that you verify the UFW firewall's current status before making any changes. Use the following command to achieve this:
sudo ufw status
You must first enable the firewall if it is not currently active. Use the following command to enable UFW:
sudo ufw enable
Step 2: Allow Cockpit Through UFW on Ubuntu
Enter the following command in your terminal to set the UFW firewall to accept incoming connections for Cockpit:
sudo ufw allow 9090
If the command runs successfully, the output should look like this:
Output
Rules updated Rules updated (v6)
This output updates IPv4 and IPv6 rules, allowing traffic on port 9090.
Step 3: Verify UFW Configuration For Cockpit on Ubuntu
It is crucial to confirm that the firewall is configured correctly and permits access to the Cockpit. Use this command to verify that the UFW rules are followed:
sudo ufw status
Port 9090 should be visible in the output as being open to incoming connections:
Output
Status: active
To Action From
-- ------ ----
9090 ALLOW Anywhere
9090 (v6) ALLOW Anywhere (v6)
Now that the firewall is set up properly, Cockpit should be reachable on port 9090, allowing you to move forward with the remaining setup and configuration steps.
Accessing the Cockpit Web Interface on Ubuntu 22.04
We'll guide you through the process of logging into the Cockpit web interface in this section. You can use the user-friendly web interface of Cockpit to manage your Linux server after you've installed, configured, and granted access via the firewall.
Step 1: Open Your Web Browser
Any device on the same network as the Cockpit server must have a web browser in order to access the Cockpit web interface. Popular web browsers like Microsoft Edge, Mozilla Firefox, and Google Chrome are available for use.
Step 2: Navigate to the Cockpit Web Interface
Enter the hostname or IP address of the Cockpit-running server in the address bar of your web browser, followed by the port number (by default, 9090) on which Cockpit is listening. The URL ought to resemble this:
https://<your-server-ip-or-hostname>:9090
For instance, if the IP address of your server is 192.168.1.100, you would type:
https://192.168.1.100:9090
Step 3: Accept the SSL Warning (Optional)
Because Cockpit by default uses a self-signed SSL certificate, your web browser might display a security warning. You can proceed without risk by acknowledging the warning and creating an exception for the Cockpit web interface, as this is standard. Depending on the web browser you're using, there are different steps to complete this.
Step 4: Log In to Cockpit on Ubuntu
