SSH and VSCodium

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
         [email protected]
     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 [email protected] >> ~/.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
