I installed the NessusWX client on Windows.

I launch the Nessus console, I do "Communications", Name=<IP address_Linux_Nessus_Server>.
Port number = 1241 (default)

Encryption=unencrypted.

Authentication
Login=admin password=mypassword


Then on the client I am getting
Error:Server doesn't support NTP/1.2 protocol. Connection terminated.

Any idea what I am missing here ? Is the NTP/1.2 the Network Time Protocol ? I am browsing through the "Help" files and it doesn't mention how to enable NTP on the Nessus server (Linux) software.
