Topic: Licence (server) for VLX?

[Peter2]

Hi

I was looking around for postings regarding "licence technique - MAC Adress, User name ...", but I think for companies with some users (> 10), a lot of PC-replacement, new users, network based AutoCAD-support and so on this way could be a little bit unhandy. Solutions with dongles are also confusing, inefficient and expensive (> 300 $ to start and 70$ per dongle ..)

Is there a "simple" solution to use and manage network-licences for VLX files?

"Free" would be fine (of course), but it not absolutely necessary. Who knows and/or has experience with this solution?

Have you looked @ Instant Plus from SoftwareKey Systems, it has the ability to offer several license schemes including trial periods, annual licensing or permanent licensing, and either automatic activation with their SOLO Server option or manual activation. 

I have one license check lisp function that all the others run first to make sure all is good.

Seemed like the most reasonable route to go at the time...

I thought all the licensing software requires a exe,dll format?

how do you do this function?

Instant plus creates a license file (actually a few) and  scatters them.  You need to create an ARX file for Acad or TX file for Briscad to trigger the Server to make sure the license is current.  It works quit well, probably not bullet proof as the code to call it is in your LISP files.  Most license servers need to be wrapped which is not possible with LISP files.

So as not to require the checking of the License status with each function, I am setting a couple of variables that each function is checking (speeds things up).  My major functions actually check the license status prior to running.

Here is their website, they also offer 30-day trial period.  http://www.softwarekey.com/

Do you have a fool-proof list / diagram / sheet which tells me what is calling / or using what?
(ARX and wrapping and scattering and ... belong to the black holes of my knowledge ..)

You can try to implement the public class of the known AES (Rijndael) algorithm...

Not a help... but.....
One of these days, when I get some chance will try open my own site and try there to sell or whatever some of my old apps....
I wrote an ARX that controls the usage of any of your applications.

It is not available to protect vlx-application in any way because it is easy to decompile it and look into the source code

I know this argument, but I don't search a 100% proof solution against 100% bad clients. There are clients / users (especially in companies > 10 and with a minimum of deceny which
- don't want ("Why should I hack? My boss should buy!)
- don't are allowed ("compliance")
- don't have economic advantages ("Why spend some hours of expensive work to hack and understand for a small tool?")
- don't know how

to hack software. And here a licence can bring an obstacle to copy and copy and copy ....
