Machine Setup Guide

Prerequisites for SSH Deployment

Before a machine can be deployed as a worker node via the casos UI, its SSH server must be configured to accept password-based root login.

WSL / Ubuntu Target Node

  1. Install the SSH server

    sudo apt update && sudo apt install -y openssh-server

  2. Start the SSH service

    sudo service ssh start

  3. Set the root password

    sudo passwd root

  4. Enable root login and password authentication

    sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
sudo sed -i 's/#PasswordAuthentication yes/PasswordAuthentication yes/' /etc/ssh/sshd_config
sudo service ssh restart

  5. Verify connectivity

    From another machine (or Windows PowerShell):

    ssh root@<machine-ip> -p 22

    You should be prompted for the root password and successfully log in.

Machine Record in casos

When adding the machine in the casos UI, set the fields as follows:

Field Value
IP WSL host IP (e.g. 172.22.149.109)
Port 22
Username root
Auth Type password
Password the root password you set above

Once connectivity is confirmed, click Deploy Node to begin worker node deployment.
