SSH Config — ssh.proud.ph

💡 How It Works

VS Code Remote-SSH uses the Host alias as a unique connection identifier. By creating multiple aliases pointing to the same server, each VS Code window gets its own independent SSH session.

mnl	→ Primary window
mnl-2	→ Second window
mnl-3	→ Third window
mnl-4	→ Fourth window

📋 SSH Config Snippet

# x1-mnl-pph-n1 — Multiple VS Code windows (alias method)
# Ref: https://stackoverflow.com/questions/78418458

# --- Primary connection ---
Host mnl
    HostName 100.120.250.96
    User xadmin
    IdentityFile ~/.ssh/id_ed25519
    StrictHostKeyChecking no
    ServerAliveInterval 60
    ServerAliveCountMax 3

# --- Second VS Code window ---
Host mnl-2
    HostName 100.120.250.96
    User xadmin
    IdentityFile ~/.ssh/id_ed25519
    StrictHostKeyChecking no

🖥️ Setup Instructions

Open your SSH config file

Windows: C:\Users\<YOU>\.ssh\config
macOS/Linux: ~/.ssh/config

Or in VS Code: Ctrl+Shift+P → "Remote-SSH: Open SSH Configuration File"

Append the config snippet

Copy the block above (or download the file) and paste it at the end of your existing SSH config. Don't remove your existing Host x1-mnl-pph-n1 entry — these are additional aliases.

Ensure your SSH key exists

The config references ~/.ssh/id_ed25519. If you use a different key, update the IdentityFile line in each alias.
Check with: ls ~/.ssh/id_ed25519*

Connect from VS Code

Ctrl+Shift+P → "Remote-SSH: Connect to Host"
Select mnl for window 1, mnl-2 for window 2, etc. Each gets its own independent session.

# Download and append in one command
curl -sL https://ssh.proud.ph/ssh-config-snippet.txt >> ~/.ssh/config

# Verify
grep -c "^Host mnl" ~/.ssh/config

# Download and append in one command
Invoke-WebRequest -Uri "https://ssh.proud.ph/ssh-config-snippet.txt" `
  -OutFile "$env:TEMP\ssh-snippet.txt"
Add-Content "$env:USERPROFILE\.ssh\config" (Get-Content "$env:TEMP\ssh-snippet.txt")

# Verify

🚀 Open Workspace (Any Machine) FIXED

The workspace file lives on the server (/var/www/www.code-workspace). Use code --remote to connect and open it — works from any machine, any OS.

# Open VS Code → connect via SSH → load full workspace
code --remote ssh-remote+mnl /var/www/www.code-workspace

# Open a SECOND simultaneous window
code --remote ssh-remote+mnl-2 /var/www/www.code-workspace

# Third / fourth window
code --remote ssh-remote+mnl-3 /var/www/www.code-workspace
code --remote ssh-remote+mnl-4 /var/www/www.code-workspace

Prerequisite: SSH aliases must be set up first (see above). The code command must be in your PATH.

💡 Create a permanent shortcut

# Add to ~/.zshrc (one-time setup, then run: source ~/.zshrc)
alias mnl='code --remote ssh-remote+mnl /var/www/www.code-workspace'
alias mnl2='code --remote ssh-remote+mnl-2 /var/www/www.code-workspace'
alias mnl3='code --remote ssh-remote+mnl-3 /var/www/www.code-workspace'
alias mnl4='code --remote ssh-remote+mnl-4 /var/www/www.code-workspace'

# Then just type:  mnl   (opens window 1)
#                  mnl2  (opens window 2)

echo -e '\n# MNL workspace shortcuts\nalias mnl="code --remote ssh-remote+mnl /var/www/www.code-workspace"\nalias mnl2="code --remote ssh-remote+mnl-2 /var/www/www.code-workspace"\nalias mnl3="code --remote ssh-remote+mnl-3 /var/www/www.code-workspace"\nalias mnl4="code --remote ssh-remote+mnl-4 /var/www/www.code-workspace"' >> ~/.zshrc && source ~/.zshrc && echo "Done! Type: mnl"

# Run once to create shortcuts in your PowerShell profile:
@'

# MNL workspace shortcuts
function mnl  { code --remote ssh-remote+mnl   /var/www/www.code-workspace }
function mnl2 { code --remote ssh-remote+mnl-2 /var/www/www.code-workspace }
function mnl3 { code --remote ssh-remote+mnl-3 /var/www/www.code-workspace }
function mnl4 { code --remote ssh-remote+mnl-4 /var/www/www.code-workspace }
'@ | Add-Content $PROFILE
. $PROFILE

# Then just type:  mnl   (opens window 1)

# macOS/Linux — download and use
curl -sL https://ssh.proud.ph/mnl-open.sh -o ~/mnl-open.sh && chmod +x ~/mnl-open.sh

# Usage:
~/mnl-open.sh       # window 1
~/mnl-open.sh 2     # window 2
~/mnl-open.sh 3     # window 3

📝 Notes

The existing Host x1-mnl-pph-n1 entry continues to work unchanged
All aliases point to the same Tailscale IP 100.120.250.96
Tailscale must be connected on your device for these to work
If you use id_rsa instead of id_ed25519, update each IdentityFile line
