I want to know if there is any good method of licensing a software inorder to protect it from reinstallation on diff't m/cs or after expiry date. The s/w is on UNIX platform

There's a whole area of computer science related to this topic and there's no real simple solution. If someone wants to spend enough time trying to crack your protection system they will. Best you can do is prevent the casual copier. Get the NIC number from the network card (using JNI or such like) and continually check that it matches the expected one. Also, remember to obfuscate your code to make reverse engineering harder.Date only methods are open to abuse - what's to stop a user resetting the date before running your program and then setting it back afterwards?

Regards.
