1/16/2024 0 Comments Matlab for mac priceNetwork: The Mathworks offers a concurrent network licensing option for Matlab. Under this agreement, there are two licensing options: I found it in the comments of this article.The campus has an annual volume purchase agreement for Matlab. =system('ifconfig') b=strfind(a,'Ether') This approach to retrieve the MAC address based on the underlying OS could be easier: switch computer('arch')Ĭ=strfind(a,'en0') if ~isempty(c),a=a(c:end) endĬ=strfind(a,'en1') if ~isempty(c),a=a(1:c-1) end Again, for compatibility reasons, this may not work on old Matlab releases, so you have to use a much more complex approach, described here. The above computation produces a character array that represents the result of the concatenation of all the MAC addresses found on the machine. Retrieve the MAC adresses of the machine network adapters using Java code as follows: mac_addrs = '' As far as I know, the most reliable property is the MAC address, because its uniqueness, althrough not granted, is almost certain and it's very unfrequent to change a network adapter (there are more chances to break an hard disk actually). If you want to adapt your licensing system to every possible OS and environment, you have to use a more generic approach, based on universally accessible hardware properties: MAC adresses, hard disk serials and such things. Unfortunately, the Window Domain Controller Security ID is another identifier that is available only on machines that run under Windows. The registry approach should be the one to use if you want to maintain a certain backward compatibility with old Matlab releases. Or through the Windows registry key HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\GroupMembership. You can retrieve it using Java code within Matlab: wdc_sid = .() Use winqueryreg to access the registry.Īnother good alternative is the Window Domain Controller Security ID, which is another machine-specific unique identifier. But it will only work on Windows machines. The first solution has been provided to you through a comment: the MachineGuid value located in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography. The final key (called LKey for example) is then computed and sent back to the user. Then, once the user inserts that it in your application, your application must send it back together with the machine properties. You release a unique code (called LID for example) when the used purchases your application. So your licensing system will work on a two-steps basis. You will not be able to know the user's machine properties in advance. But keep in mind that if one or more properties of the user machine change (because he changes a device or reinstalls his OS), his license will be invalidated and you will have to provide a customer assistance service that takes care of this kind of situations. A pseudo-code example: mp1 = GetMachineProperty1() Within the application, you must implement the same logics that allowed your form to create the license code, because you will need to use them in order to validate the code itself every time your application starts. That page will be in charge to validate the machine properties, receive the payment and, finally, deliver a valid license code based on these properties. When it is clicked, the application retrieves the machine properties and passes them to the web page / form that will be opened to let the user perform the payment. Within the application, you create a Register Now button somewhere. You check against the expiration date when the application starts and, once it is reached, you throw an error and you don't let the used play with your application anymore. When it is started for the first time, you set an expiration date in the registry or in a file well hidden somewhere. before the user decides to buy your application.If one user decides to spread his license file worldwide, you are doomed because everyone could potentially take that license file and use it to unlock your application.īut if you link your license files to one or more properties of a user machine, as mentioned above, you must be able to obtain these properties either: If you don't to this, you are just going to release licenses that can be transferred from one user to another. In order to create an effective licensing system, you have to link it to one or more properties of a user machine (MAC address, OS ID, hard disk serial numbers, CPU serial numbers, etc.).
