each time a handler is spawned is it client specific? in other words
when two clients send something to the server do handlers spawn for
each of them or does everything just go into a single handler?

docstring of the example:

"""
The RequestHandler class for our server.

It is instantiated once per connection to the server, and must
override the handle() method to implement communication to the
client.
"""

If you want data persistant over connections, store them in your handler
class.

class MyTCPHandler(SocketServer.BaseRequestHandler):
cnxNumber = 0
def handle(self):
# self.request is the TCP socket connected to the client
self.data = self.request.recv(1024).strip()
# just send back the same data, but upper-cased
self.request.send(self.data.upper())
cnxNumber +=1
print "handling connection N�%s" % cnxNumber

thanks JM,

at this point i switched over to this scheme and now I'm getting an
error durring instantiation of the server:
Server.py:
from Crypto.PublicKey import RSA
from ServerNegotiator import ServerNegotiator
from sharedComs import *

f = open("hostid")
tup = stringToTuple(f.readline()[0:-1])
HostID = f.readline()[0:-1]
f.close()

key = RSA.construct((long(tup[0]),long(tup[1]), long(tup[2]),
long(tup[3]),
long(tup[4]),long(tup[5])))
host = "localhost"
port = 8005

servernegotiator = ServerNegotiator(host,HostID, port, key)
servernegotiator.start()


ServerNegotiatior.py lines 185 - end
class ServerNegotiator:
def __init__(self, host, port, hostid, rsa_key, buf = 512):
negotiator = Negotiator(host, hostid, rsa_key,buf)
self.server = SocketServer.TCPServer((host, port), negotiator)

def start(self):
self.server.serve_forever()





Traceback (most recent call last):

Argument mismatch?
