Andrew,
Thanks for your response and suggestions - although i'm still having
issues with the code.

*although "p" vs. "P" did get rid of the intital error.

I looked into other multithreaded examples on the web and came up with
the following:

=============================
import threading, os

def log(s):
    print s

class Pinger(threading.Thread):
    def __init__(self, address, *args, **kwargs):
        self.address = address       
        threading.Thread.__init__(self, *args, **kwargs)        

    def run(self):
        pingCard = "ping -n 10 " + self.address
        child = os.popen(pingCard).readlines()
        log(child)      


if __name__ == '__main__':
    
    PingList = ["127.0.0.1", "66.218.71.83", "64.66.148.171"]
    threadList = []
    
    # Create threads
    for i in PingList :        
        threadList.append(Pinger(i))

    # Start all threads
    for thread in threadList:
        thread.start()
============================================

when run through idle, the python shell hangs after all the ips
respond. Do I have to stop each thread individually after it executes
the ping command? other than that it seems to work....

thanks again
