1. Update and Install OpenSSH Server in WSL:

Open your Ubuntu 22.04 WSL distribution and Update the package lists.

Code

  sudo apt update

Install the OpenSSH server.

Code

  sudo apt install openssh-server

enable and start the ssh service.

Code

  sudo systemctl enable ssh --now

2. Configure SSH in WSL (Optional but Recommended):

• Edit the SSH configuration file to enhance security (e.g., change the default port, disable password authentication for key-based authentication):

Code

  sudo nano /etc/ssh/sshd_config

• Modify or add lines as needed (e.g., Port 2222, PasswordAuthentication no, PubkeyAuthentication yes).
• Save and exit the file.
• Restart the SSH service for changes to take effect:

Code

  sudo service ssh restart

3. Set Up Port Forwarding on Windows:

• Open PowerShell as Administrator on your Windows host.
• Get the IP address of your WSL instance and set up port forwarding. Replace 2222 with your chosen SSH port if you changed it in sshd_config:

Code

  $wsl_ip = (wsl hostname -I).trim()
  netsh interface portproxy add v4tov4 listenport=2222 listenaddress=0.0.0.0 connectport=2222 connectaddress=$wsl_ip

4. Configure Windows Firewall:

• Open Windows Defender Firewall with Advanced Security.
• Create a new Inbound Rule:
  • Select "Port" and click Next.
  • Choose "TCP" and enter the port number you are using for SSH (e.g., 2222).
  • Allow the connection and apply the rule to all profiles. 
  • Name the rule (e.g., "WSL SSH") and finish the wizard. 

5. Generate and Copy SSH Key (for key-based authentication):

• Generate Key on Client (e.g., your Windows machine or another remote machine):

using tapes on Hercules

group post

Instead of using "touch" to create the tape. Which, by-the-by would

not initialize the VOL1 an other header records, I'd use the hetinit

command. You have two choices. AWS format or HET format. hetinit

will create either, but defaults to het. Note also that het

formatted files must end in ".het" to be recognized by hercules as

such.

hetinit -d tape580.tape.aws 123456 owner
