Issue Summary

GUID duplication on Linux-based WAVE servers can block servers from merging and may disrupt the WAVE Sync service on non-merged servers. 

This article explains how to identify duplicate GUIDs and generate a new GUID by recreating the mediaserver.conf file.

Resolution

Verify the Server GUID

To verify the server GUID:

1. Click the Linux version of a Start ()button in the lower left corner of the screen.
    
2. Enter Terminal then click the Terminal () icon.
    

3. Enter ls /usr/local/src/hit/scripts/ and press Enter.
   
   

   IMPORTANT: If the script version on your device is less than version 1.03,
   upgrade the operating system on that WRN. 

4. Enter cat /opt/hanwha/mediaserver/etc/mediaserver.conf and press Enter.
    
5. Repeat the cat command (in step 4) on both servers and compare the GUID.
   
   Example: serverGUID={985fec24-20af-6355-d06d-8e4b416261c1}
   
   Proceed to the next step if both servers have the same GUID.

Generate a New GUID

To generate a new GUID:

1. Enter sudo -s 
    
2. Enter the Linux password (with no spaces) and press Enter.
    
3. Enter systemctl stop hanwha-mediaserver and press Enter.
    
4. Enter nautilus to open a GUI and press Enter.
    
5. In Nautilus, navigate to /opt/hanwha/mediaserver/etc
    
6. Locate the mediaserver.conf and delete it.
    
7. Return to the Terminal window and enter sudo -s 
    
8. Enter the Linux password and press Enter.
    
9. Enter systemctl start hanwha-mediaserver and press Enter.
   
   The WAVE server service will generate a new mediaserver.conf file with a random GUID to allow for merging with another WRN.
