I want to access my servers via SSH in VSCodium. Let’s setup a plain Debian 11 host and Home Assistant 10.

VSCodium

1. Install VSCodium extension: jeanp413.open-remote-ssh

   • Configure the extension per the instructions.

   • In file ~/.vscode-oss/argv.json add the following code to the bottom of the file and save

    {
        "enable-proposed-api": [
            "jeanp413.open-remote-ssh",
        ]
    }
   

   • reload VSCodium

Remote Hosts

The basic gist is:

1. Add SSH public key
2. SSH config: Allow TCP forwarding
3. Install dependencies (e.g. curl)

Home Assistant

1. Install Home Assistant Community Add-on: Advanced SSH & Web Terminal Note the Official add-on Terminal & SSH does not support the port forwarding.

2. Configure Advanced SSH & Web Terminal N.B. This is setup with root as the SSH user. I tried creating another user but the new user couldn’t do what I needed right away, even when adding them to the root group.

    ssh:
      username: root
      password: ""
      authorized_keys:
        - >-
          ssh-ed25519
          AAAAC3NzaC1lZDI1NTE5AAAAIIpnKCXYVleM0ikozrgmQKQ18nZUEGX+OT/X4fEJxotq
          josh@doiotyourself.com
      sftp: false
      compatibility_mode: false
      allow_agent_forwarding: false
      allow_remote_port_forwarding: true
      allow_tcp_forwarding: true
    zsh: true
    share_sessions: false
    packages:
      - gcompat
      - libstdc++
      - curl
    init_commands: []
   

3. If Home Assistant is not a host in ~/.ssh/config then add it:

    Host 192.168.107.17
        User root
   

4. Connect to Home Assistant FTW

Debian Server

1. Copy your public key to the Debian Server

    josh@debian:~$ mkdir -p ~/.ssh
    josh@debian:~$ echo ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIIpnKCXYVleM0ikozrgmQKQ18nZUEGX+OT/X4fEJxotq josh@doiotyourself.com >> ~/.ssh/authorized_keys
    josh@debian:~$ chmod -R go= ~/.ssh
   

2. Test that you can authenticate to Debian Server Using SSH Keys

3. More SSH configuration

    josh@debian:~$ su -
    Password:
    root@debian:~# nano /etc/ssh/sshd_config
   

    AllowTcpForwarding yes
    # And while we're here, let's improve security
    PermitRootLogin no
    PasswordAuthentication no
   

    root@debian:~# systemctl restart ssh
   

4. Install sudo

    # su -
    Password: 
    # apt install sudo
    # usermod -aG sudo josh
    # getent group sudo
    sudo:x:27:josh
    # logout
    ~ logout 
   

5. Install curl on Debian Server

    root@debian:~# apt install curl
   

6. Connect to Debian Server FTW
