As written, you have a local varaible running in method run that gets set
and never changes.  The class variable you're looking for is Server.running,
like this:

import time, threading

class Server(threading.Thread):
    running = 0

    def run(self):
        Server.running = 1
        while Server.running:
            print "do something here..."

    def stop(self):
        Server.running = 0

server = Server()
print server.running        # should print "1"
