Duplicate MAC Addresses

If you encounter an issue with certain components installed on your computer, such as Fortinet, that assign the same MAC address to all machines, this causes a problem in Medulla where the machines do not register in the correct entities and are reported in GLPI with a UUID that already exists for another machine:  
 In the file /etc/pulse-xmpp-agent-substitute/registeryagent.ini.local 
 add the following section and information, ensuring you use the correct case. 
 [parameters]
blacklisted_mac_addresses = 00\:00\:00\:00\:00\:00, 00\:09\:0f\:aa\:00\:01 
 In /etc/pulse-xmpp-agent-substitute/registeryagent.ini.local, add the MAC addresses to be blacklisted 
 00\:00\:00\:00\:00\:00 must be present Colons must be escaped, and addresses must be separated by commas
