python: how to send packets in multi thread and then the thread kill itself

Question

I have a question. I\'d like to send a continuous streams of byte to some host for certain amount of time (let\'s say 1 minute) using python.

Here is my code so far

I don't know how to do this with the "thread" module, but I can do it with the "threading" module. I think this code accomplishes what you want.

For documentation on the threading module: http://docs.python.org/library/threading.html

#!/usr/bin/python

import time
from threading import Thread
import threading
import sys

test_time = 10
killed = False

class SillyThread( threading.Thread ):
    def run(self):
        global killed
        starttime = time.time()
        counter = 0
        while (time.time() - starttime) < test_time:
            if killed:
                break
            counter = counter + 1
            time.sleep(0.1)
        print "I did %d loops" % counter

class ManageThread( threading.Thread ):
    def run(self):
        global killed
        while True:
            var = raw_input("Enter something: ")
            if var == "quit":
                killed = True
                break
        print "Got var [%s]" % var

silly = SillyThread()
silly.start()
ManageThread().start()
Thread.join(silly)
print "bye bye"
sys.exit(0)

Note that I use time.time() instead of time.clock(). time.clock() gives elapsed processor time on Unix (see http://docs.python.org/library/time.html). I think time.clock() should work everywhere. I set my test_time to 10 seconds because I don't have the patience for a minute.

Here's what happens if I let it run the full 10 seconds:

leif@peacock:~/tmp$ ./test.py
Enter something: I did 100 loops
bye bye

Here's what happens if I type 'quit':

leif@peacock:~/tmp$ ./test.py
Enter something: quit
Got var [quit]
I did 10 loops
bye bye

Hope this helps.
