⌘ Server Commands

🏥Health Check ▶

Verify Meridian is alive and the session is active.

Connect & Check

ssh aiciv@37.27.237.109

tmux list-sessions

systemctl status meridian-session.service --no-pager

systemctl status meridian-telegram.service --no-pager

exit

Healthy: You should see an active tmux session like "meridian: 1 windows (created ...)"
Unhealthy: "no server running on /tmp/tmux-1000/default" means Meridian needs a restart.

📺Live Monitoring ▶

Watch exactly what Meridian is doing in real time.

Connect & Attach

ssh aiciv@37.27.237.109

tmux list-sessions

tmux attach -t meridian

IMPORTANT: Always detach with Ctrl+B then D. Never close terminal while attached.

Quick Peek (without attaching)

tmux capture-pane -t meridian -p | tail -30

🔄Restart Procedures ▶

Full clean restart when Meridian is unresponsive or stuck. Takes approximately 60-90 seconds.

🔑Mac SSH Key Setup ▶

One-time setup to enable password-less SSH from your Mac.

Step 1: Check for Existing Keys

ls ~/.ssh/id_ed25519.pub ~/.ssh/id_rsa.pub 2>/dev/null

If a key file is listed, skip to Step 3. If nothing shows, create one in Step 2.

Step 2: Generate New Key

ssh-keygen -t ed25519 -C "meridian-access"

Step 3: Copy Key to Server

ssh-copy-id aiciv@37.27.237.109

Step 4: Create Quick Alias

echo "alias meridian='ssh -t aiciv@37.27.237.109 bash /home/aiciv/civ/tools/connect-meridian.sh'" >> ~/.zshrc && source ~/.zshrc

After setup, just type meridian in any terminal to connect.

⚡One-Word Terminal Setup ▶

After SSH key setup, create a magic word that instantly connects you to Meridian's live session.

Server-side: Create connect-meridian.sh

#!/bin/bash # connect-meridian.sh — placed on the server at /home/aiciv/civ/tools/ SESSION=$(tmux list-sessions -F '#{session_name}' 2>/dev/null | head -1) if [ -z "$SESSION" ]; then echo "No active Meridian session found." exit 1 fi echo "Attaching to Meridian session: $SESSION" tmux attach -t "$SESSION"

Mac-side: Add Alias

echo "alias meridian='ssh -t aiciv@37.27.237.109 bash /home/aiciv/civ/tools/connect-meridian.sh'" >> ~/.zshrc && source ~/.zshrc

The -t flag is critical. The alias MUST include -t in the SSH command for tmux to work properly.

Usage

meridian

Type meridian in any terminal → instantly see what Meridian is doing. Disconnect safely with Ctrl+B then D.
