When we install software on a hosting server, I want to prevent it from being copied to a new server without our knowledge In other words, I want to tie a specific copy of our software to a specific server and I am looking for the best way to do this. One thought I had would be to to read the server's UUID and compare it to an encrypted version of the UUID. Someone told me that the UUID so this wouldn't work but that is not my impression.
Are there other ways to uniquely identify the server that the software is on. I can't guarantee that the fully qualified domain name will work because not all servers have the fqdn assigned. What else can be done?
