SSH Connection to VirtualBox Docker WSL2: Troubleshooting

Troubleshooting SSH Connection to VirtualBox VM, Docker Container Running on WSL2

Establishing an SSH connection to a VirtualBox VM or Docker container running on WSL2 can sometimes be challenging. This article aims to help you troubleshoot and resolve common issues that may arise during the process.

1. Verify WSL2 and VirtualBox Configuration

First, ensure that your WSL2 and VirtualBox configurations are correct. To do this, follow these steps:

1. Check that WSL2 is enabled on your system.
2. Install the VirtualBox extension pack to enable USB 2.0/3.0 support.
3. Create a new VM in VirtualBox and configure it to use WSL2 as the boot driver.

2. Configure SSH on the VM

After configuring VirtualBox, ensure that SSH is properly set up on the VM. To do this, follow these steps:

1. Install an SSH server on the VM, such as OpenSSH.
2. Configure the SSH server by editing the /etc/ssh/sshd_config file.
3. Start the SSH server by running service ssh start or systemctl start sshd.

3. Check Network Settings

Check that the network settings for the VM and the Docker container are correct. To do this, follow these steps:

1. Ensure that the VM and the Docker container are on the same network.
2. Check that the IP addresses and port numbers are correct.
3. Verify that the firewall settings allow incoming SSH connections.

4. Test the SSH Connection

After configuring the network settings, test the SSH connection by running the following command:

ssh -p 22 @

5. Troubleshoot Common SSH Connection Issues

If you are still unable to establish an SSH connection, try the following troubleshooting steps:

1. Check the SSH logs for error messages.
2. Ensure that the SSH server is running and listening on the correct port.
3. Verify that the user account and password are correct.
4. Check that the firewall settings allow incoming SSH connections.
5. Try restarting the SSH server and the VM.
