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:

   scp new_license.lic root@dalidou:/opt/Siemens/LicenseServer/License_Ugslmd.lic
   

3. Restart the service:

   ssh root@dalidou "systemctl restart siemens-lmgrd"
   

4. Verify:

   ssh root@dalidou "cd /opt/Siemens/LicenseServer && ./lmutil lmstat -a"

   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

# Check if running
ssh root@dalidou "ps aux | grep lmgrd"

# 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"
