Initial Setup

First Login

1. Navigate to https://termix.manticorum.com
2. Create admin account on first run
3. Important: Enable 2FA immediately after account creation

Add Your First Server

1. Click "Add Host" or "+"
2. Enter connection details:
   • Hostname: Server IP or hostname (e.g., 10.10.0.33)
   • Port: 22 (default SSH)
   • Username: SSH user (e.g., cal or root)
   • Auth: SSH key (recommended) or password
3. Test connection
4. Organize with tags (e.g., proxmox, docker, production)

Deploy SSH Keys

Termix can generate and deploy SSH keys to your servers:

1. Generate key pair in Termix
2. Use "Deploy SSH Key" feature
3. Termix will add the key to ~/.ssh/authorized_keys on target server

Organize Servers

Create folders for organization:

• By Environment: production/, development/, homelab/
• By Function: docker-hosts/, databases/, proxmox/
• By Location: local/, cloud/

Quick Import: All Home Lab Servers

A pre-configured JSON import file is available with all your home lab servers:

File: server-configs/termix/homelab-hosts-import.json

Import Instructions

1. Log into Termix at https://termix.manticorum.com
2. Go to Settings → Import/Export
3. Click Import Hosts
4. Upload homelab-hosts-import.json
5. All 12 servers will be imported with:
   • Organized folders (Infrastructure, LXC Containers, VMs, Cloud)
   • Appropriate tags for filtering
   • Docker management enabled for Docker hosts
   • File manager with correct default paths
   • System monitoring enabled
   • Database tunnel pre-configured for strat-database

After Import: Configure SSH Keys

The import uses SSH key authentication. After importing:

1. Go to each host in Termix
2. Edit host settings
3. Add your SSH private key or generate a new one in Termix
4. Use Termix's "Deploy SSH Key" feature to add keys to servers

Or use password authentication temporarily:

• Edit each host and change authType to "password"
• Add password in the password field
• Later switch to SSH keys for security

Backup

What to Backup

1. Termix database: /opt/termix/data/ (contains all settings, credentials, SSH keys)
2. Docker compose: /opt/termix/docker-compose.yml
3. Environment: /opt/termix/.env (if exists)

Backup Commands

# Full data directory (includes encrypted database)
tar -czf termix-backup-$(date +%Y%m%d).tar.gz /opt/termix

# Database only
cp /opt/termix/data/termix.db /backups/termix-db-$(date +%Y%m%d).db

Restore

# Stop Termix
cd /opt/termix
docker compose down

# Restore data
tar -xzf termix-backup.tar.gz -C /

# Start Termix
docker compose up -d

Upgrades

Update Termix

cd /opt/termix

# Pull latest image
docker compose pull

# Restart with new image
docker compose down

# Check logs for successful start
docker compose logs -f

Integration with NPM

Configure reverse proxy on NPM (10.10.0.16):

• Domain: termix.manticorum.com
• Scheme: http
• Forward Hostname/IP: 10.10.0.210
• Forward Port: 8180
• SSL: Let's Encrypt
• Websockets: ✅ MUST BE ENABLED (required for terminal sessions)
• Block Common Exploits: Enabled
• Cache Assets: Disabled (for real-time terminal)

Troubleshooting

Container won't start

# Check logs
docker compose logs

# Common issues:
# - Port 8080 already in use
# - Missing /opt/termix/data directory
# - Permissions on data directory

Can't connect to servers from Termix

# Ensure Termix container has network access
docker exec -it termix ping 10.10.0.11

# Check SSH from container
docker exec -it termix ssh -v user@server-ip

# Verify firewall rules on target servers

502 Bad Gateway on web

# Check Termix is running and listening
docker compose ps
docker compose logs

# Test local connection
curl http://localhost:8080

# Verify NPM can reach container
curl http://10.10.0.226:8080

Terminal sessions disconnect

• Ensure websockets are enabled in NPM
• Check for network connectivity issues
• Verify Termix auto-reconnect settings

Database corruption

# Stop Termix
docker compose down

# Restore from backup
cp /backups/termix-db-YYYYMMDD.db /opt/termix/data/termix.db

# Start Termix
docker compose up -d

Security Notes

• All credentials are encrypted in SQLite database
• SSH keys are stored securely within Termix
• Enable 2FA for all users
• Use SSH key authentication instead of passwords where possible
• LXC is unprivileged for better isolation
• Termix only accessible via HTTPS through NPM
• Consider restricting NPM access to internal network only

Advanced Configuration

OIDC Integration

For single sign-on with external identity provider:

1. Configure OIDC provider (e.g., Authelia, Keycloak)
2. Add OIDC settings to Termix via environment variables
3. Enable OIDC login in Termix settings

Custom Themes

Termix uses Tailwind/Shadcn UI. Themes can be customized if building from source.

Multi-User Setup

1. Create user accounts in Termix admin panel
2. Assign roles (Admin, User, Viewer)
3. Set per-user server access permissions
4. Enforce 2FA for all users
