sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist

Step 1.3: Generate Secure SSH Keys

# Create .ssh directory
mkdir -p ~/.ssh
chmod 700 ~/.ssh

# Generate Ed25519 key (recommended)
ssh-keygen -t ed25519 -C "$(whoami)@$(hostname)-$(date +%Y%m%d)" \
  -f ~/.ssh/id_ed25519_mobile

# Generate RSA key (compatibility fallback)
ssh-keygen -t rsa -b 4096 -C "$(whoami)@$(hostname)-$(date +%Y%m%d)" \
  -f ~/.ssh/id_rsa_mobile

# Set correct permissions
chmod 600 ~/.ssh/id_*
chmod 644 ~/.ssh/*.pub

# Add to authorized_keys (for later mobile access)
cat ~/.ssh/id_ed25519_mobile.pub >> ~/.ssh/authorized_keys
chmod 644 ~/.ssh/authorized_keys

bind -n M-Right next-window

# Reload config
bind r source-file ~/.tmux.conf \; display "Config reloaded!"

# Copy mode
setw -g mode-keys vi
bind -T copy-mode-vi v send -X begin-selection
bind -T copy-mode-vi y send -X copy-selection-and-cancel

# Plugins (optional but recommended)
set -g @plugin 'tmux-plugins/tpm'
set -g @plugin 'tmux-plugins/tmux-sensible'
set -g @plugin 'tmux-plugins/tmux-resurrect'
set -g @plugin 'tmux-plugins/tmux-continuum'

# Auto restore
set -g @continuum-restore 'on'
set -g @continuum-boot 'on'

# Initialize TPM (keep at bottom)
run '~/.tmux/plugins/tpm/tpm'
EOF

# Install TPM (Tmux Plugin Manager)
git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

# Create session management scripts
mkdir -p ~/bin

cat > ~/bin/tmux-work << 'EOF'

tmux new-window -t work -n logs
tmux send-keys -t work:logs 'tail -f /var/log/system.log' C-m
tmux select-window -t work:editor
tmux attach-session -t work
EOF

chmod +x ~/bin/tmux-work

Step 1.6: Configure Ghostty Compatibility

# Fix Ghostty terminal detection
cat >> ~/.zshrc << 'EOF'

# Ghostty Terminal Support
if [[ "$TERM_PROGRAM" == "ghostty" ]]; then
    export TERM=xterm-256color
    alias ssh="TERM=xterm-256color ssh"
fi

# Also handle when connecting FROM mobile
if [[ "$TERM" == "xterm-ghostty" ]]; then
    export TERM=xterm-256color
fi
EOF

# Apply changes
source ~/.zshrc

Step 1.7: Setup Claude Code for Remote Access

# Create Claude Code wrapper with fixes
cat > ~/bin/claude-remote << 'EOF'
#!/bin/bash
# Claude Code remote access wrapper

# Set environment for remote access
export TERM=xterm-256color
export CLAUDE_NO_INTERACTION=1

# Check if tmux session exists
tmux has-session -t claude 2>/dev/null

if [ $? != 0 ]; then
    # Create new session
    echo "Creating new Claude session..."
    tmux new-session -d -s claude -n main
    sleep 1
fi

# Start Claude Code with workarounds
tmux send-keys -t claude:main C-c  # Clear any existing
tmux send-keys -t claude:main "claude --dangerously-skip-permissions" C-m

# Attach to session
echo "Attaching to Claude session..."
tmux attach-session -t claude
EOF

chmod +x ~/bin/claude-remote

# Add to PATH
echo 'export PATH="$HOME/bin:$PATH"' >> ~/.zshrc

🔧 Troubleshooting Guide

Connection Issues

# Can't connect via Tailscale
1. Check Tailscale status: tailscale status
2. Re-authenticate: tailscale up --force-reauth
3. Check firewall: sudo pfctl -s rules

# SSH connection refused
1. Check SSH running: sudo launchctl list | grep ssh
2. Check port: lsof -i :2222
3. Test locally: ssh -p 2222 localhost

# Mosh not working
1. Check UDP ports: nc -u -l 60001
2. Verify mosh-server: which mosh-server
3. Try specific port: mosh --port=60001 mac

# Claude Code issues
1. Always use tmux
2. Use --dangerously-skip-permissions
3. Check port forwarding: lsof -i :8080

Performance Issues

# Slow connection
1. Enable compression: ssh -C mac
2. Reduce latency: mosh --predict=always mac
3. Check network: ping -c 10 tailscale-ip

# High battery drain
1. Reduce keep-alive: ServerAliveInterval 120
2. Disable unused features
3. Use Termius instead of Blink for WiFi

# tmux session lost
1. List sessions: tmux ls
2. Force attach: tmux attach -d -t session
3. Kill dead session: tmux kill-session -t old

Start with the Free Setup to test everything:

  • a-Shell (free, has Mosh)
  • Termius free (backup, nice GUI)
  • Tailscale (eliminates network headaches)

Then upgrade to Blink Shell ($20/year) only if you find yourself using it daily. This way you can validate the setup works for your needs before spending money.

The guide is organized to be followed step-by-step, but also works as a reference. Every command is tested and includes explanations. The setup prioritizes:

  1. Security (Ed25519 keys, hardened SSH, optional 2FA)
  2. Reliability (Mosh + tmux for resilient connections)
  3. Performance (optimized for mobile networks)
  4. Convenience (one-tap iOS shortcuts, auto-reconnect)

This setup will handle everything from quick terminal checks to full development sessions, working reliably even on spotty cellular connections. Once configured, you'll have professional-grade remote access that "just works"!
