## Server Installation (Already Done on Dalidou)

### Location
```
/opt/Siemens/LicenseServer/
├── lmgrd           # FlexNet license manager
├── saltd           # Siemens vendor daemon (v5)
├── ugslmd -> saltd # Symlink for compatibility
├── lmutil          # License utilities
├── License_Ugslmd.lic  # License file
└── logs/
    └── lmgrd.log   # Server log
```

### Systemd Service
```bash
# Service file: /etc/systemd/system/siemens-lmgrd.service
sudo systemctl status siemens-lmgrd   # Check status
sudo systemctl start siemens-lmgrd    # Start
sudo systemctl stop siemens-lmgrd     # Stop
sudo systemctl restart siemens-lmgrd  # Restart
```

### Manual Commands
```bash
cd /opt/Siemens/LicenseServer

# Check license status
./lmutil lmstat -a

# Check specific feature
./lmutil lmstat -f NX93300

# View log
tail -50 logs/lmgrd.log

# Start manually (if systemd not working)
./lmgrd -c License_Ugslmd.lic -l logs/lmgrd.log
```

### Firewall
```bash
# Port 28000 is open
sudo ufw status | grep 28000
```

## Updating the License File

When you receive a new license from Siemens:

1. **Edit the SERVER line** to match dalidou:
   ```
   SERVER dalidou ANY 28000
   VENDOR ugslmd
   ```

2. **Copy to dalidou:**
   ```bash
   scp new_license.lic root@dalidou:/opt/Siemens/LicenseServer/License_Ugslmd.lic
   ```

3. **Restart the service:**
   ```bash
   ssh root@dalidou "systemctl restart siemens-lmgrd"
   ```

4. **Verify:**
   ```bash
   ssh root@dalidou "cd /opt/Siemens/LicenseServer && ./lmutil lmstat -a"
   ```

## ThinkPad Setup (When Repaired)

On your ThinkPad, follow the same **Client Setup** steps above:

1. Set `SPLM_LICENSE_SERVER` environment variable:
   ```
   28000@dalidou;28000@100.80.199.40
   ```

2. Make sure **Tailscale** is installed and connected

3. Test with Siemens Licensing Tool

That's it - no license server installation needed on the ThinkPad!

## Troubleshooting

### License server not responding
```bash
# Check if running
ssh root@dalidou "ps aux | grep lmgrd"

# Check log for errors
ssh root@dalidou "tail -50 /opt/Siemens/LicenseServer/logs/lmgrd.log"

# Restart
ssh root@dalidou "systemctl restart siemens-lmgrd"
```

### Can't connect from laptop
1. Check Tailscale is connected: `tailscale status`
2. Ping dalidou: `ping 100.80.199.40`
3. Check firewall: `ssh root@dalidou "ufw status"`

### "All licenses in use" error
Only 1 seat per license - close NX on other machines first.
