Corona network licence

[Chris_Arko]

I've recently taken over the running of our CGI dept and we've had some issues with Corona Licencing.

We have a Licence service running on one machine as per https://coronarenderer.freshdesk.com/support/solutions/articles/5000618553-corona-licensing-server suggested set-up.  what i'm having trouble understanding is how do the other machines know where to look for that licence server?  it seems the only way i can licence the other machines is to manually fill in the FairSaaS info.  when you have many machines this is a bit of a pin to do.

This is a quote from the helpdesk page you mentioned:

The licensed computers discover the licensing server using a UDP broadcast

That means your nodes are basically shouting into the network "is anyone there who can give me a license?" - similar case is searching for a DHCP server for example. You just have to ensure that the licensing server can be reached by the nodes, especially when using any firewalls.

Since it is not directly mentioned on the helpdesk page, here is something you might want to check:

In %userprofile%\Appdata\Local\CoronaRenderer\LicensingLog.txt on a node you can see what's happening (or not) when Corona tries to obtain a license. If everything runs properly, it should look like this when using a license server:

Thank you for the speedy reply.

I checked the .txt file as you mentioned and bvecause i've manually activated the licenses it's using that.  i suspect the firewall is bloacking the nodes from looking for the network licence so may have to speak to our IT People about that.

How do i stop the nodes using the online licence and look for the Network licence.  I'm sorry if i sound like a simpleton but networks are not my thing.

the online licence

I assume you have chosen the CoronaActivation.txt method containing email+pwd? So if you want to remove a license from a node to test connectivity again, it should be enough to remove "CoronaActivation.txt" and "token-3dsmax.txt" from the directory where you already found the activation log (btw: using the licensing server is also a "online license", it just acts as a "proxy" for your nodes and will also need internet connection).


Good Luck

I just wanted to say Thank you Frood.  Everything working brilliantly now.  The main problem being that the License server wasn't running as a service!

But i unloaded the Login and password info as you mentioned and then it found the network license.

Cheers again

Glad to see it's working now. And thanks for the feedback,


Good Luck
