Thanksfor your response Gilles.
I have tried the latest version of the agent. However when it registers to the OCS server, it incorrectly updates the IP Network information as well as providing the wrong MAC address ... This means you cannot search for the computer by IP address in the OCS dashboard.
I believe it's likely a bug - has anyone found a simliar issue with agents on CentOS 7 talking to older OCS servers in the OCS community?
Thanks for any response!
