Authorization and licensing issues

Dear Administrator

Although you have already explained the concept of “open source” on the community homepage, I hope you can answer.

a. I have set up a small local area network by myself, with 6 to 800 hosts that need to pass the RUDES security certification. Do I need to pay a certain fee to use your open-source software?

b. Is there a limit on the number of trial users for the currently available download version? And are there any restrictions on concurrency?

Looking forward to your reply. Thank you.

No

It depends on the component or the plugin you are using
