It just seems to me that all the recent DA installs have to contact the license server at some point.
Yes, every version after 1.643 is using the new licening system so indeed DA installs contact the license server regularly. Lot of users still use that too and it's legal to use an old version.
But the license server can not determine if a license is valid or not. Hmmz.. how can I give a good example.
I don't know if this is a good one but I will try. Also I don't want to give out too much info about how system might be tricked, to prevent others from getting idea's here. So it's a bit of a hard one to make this clear and make it better argumental.
Oke suppose you sell me your internal licenses. Now I change the netblock and I start using the licenses.
How can the licensing server determine that I'm having rented a server of you on a different netblock or that I just am abusing the licenses because I should have been able to buy them without servers? Licensing server all doesn't know that. It knows there is an account, which x licenses so x ip's can be used so x amount of license keys can be used.
There is some more trickery to this but I won't go giving better examples or additional options about this one in public.
So as you can see, the licensing system can't determine that I'm using in fact illegal licenses at the moment. There sure are other tricks to find out. But since there are many many many licenses out there, it's an enormous work anyway.
So it's not like using the same license on multiple servers, it's using licenses from company's who stopped or using licenses from company's illegaly selling them or selling part of their licenses.
In fact it's legal to use the same license on 2 servers, but only when moving servers. And for sure you're not the only one testing things. Nothing wrong with testing. But there is a difference between testing and abusing. We don't abuse.
If it was so easy to stop that abuse, they would have done it already. But they are too friendly.
And as you can see from the few complaints here, did you see how hard it is to even get decent verification info that they are indeed valid owners? How they talk and talk and turn around continuously but without giving the information? And even if giving information, it's not the same what DA is asking for?
And then we're just here on the forum with 2 persons until now. This gives me (imho) an impression as to what is going on in the ticket system, because they also open multiple tickets as you could read.
So well.. if you would have a very good idea how to catch those, I think DA would be very interested.
