I developed some software which I want to license. In Windows its pretty much easier as you can make expiration trial and keys for activation. Please dont go into it can be cracked and stuff, everything can, but the average user will not, or it will take him time on which he ratter just paid. Now I have it running on linux as well but I dont know how I can make the same license model in Linux. Is there a way to make license server check on Linux and trial expirations? Its seems there very few softwares actually on a trial period for Linux, mostly because as its open source everyone can modify everything. My installer basically creates some php, databases, etc. Im interested on license check from the server for Linux and how to block the full thing if its fails.
I wanted to update, that what im asking is not how to protect the files, you can do this with encoding, but if someone knows a script to verify license, or is it that in Linux the all free moto just makes developers not interesting into licensing for Linux it may be.
Actually there are some commercial softwares in Linux, for example Visual Paradigm and Intellij IDEA. These softwares save license information on per user basis (in home directory). In Linux it's pretty easy to find a particular software's settings as they usually saved in their own folders and these folders are very easy to delete.
