This milestone we have changed which server the extension downloads depending on the OS support, the following test plan is to ensure successful connection over the different scenarios

Using Docker, set up a legacy VM on localhost that you can SSH into.

1. Run docker run -p 2222:22 -it centos:7

2. Run these commands. The last command will run the SSH server and block:

   > yum install openssh-server -y
   > echo 'root:mellon' | chpasswd
   > sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
   > sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
   > ssh-keygen -A
   > /usr/sbin/sshd -D
   

3. In VS Code, run Remote - SSH: Connect current window to host. Add a new host using the command ssh root@localhost -p 2222.

4. Connect to the host, using the password mellon when prompted. (If asked for an SSH key password, just hit enter so that it asks you for the root user password instead). Verify it works.

5. In your user settings, set remote.SSH.useExecServer: false

6. Reload the window and repeat step 4
