Can you include the full command line you are running, the full source file you are working with (or, preferably, a shorter one that demonstrates the same problem), and the full text of the error you receive, including the traceback if there is one?

# Here is the script finger.tac (exact copy of tut. step 11)

from twisted.application import internet, service
from twisted.internet import protocol, reactor, defer
from twisted.protocols import basic
class FingerProtocol(basic.LineReceiver):
    def lineReceived(self, user):
        self.factory.getUser(user
        ).addErrback(lambda _: "Internal error in server"
        ).addCallback(lambda m:
                      (self.transport.write(m+"\r\n"),
                       self.transport.loseConnection()))
class FingerFactory(protocol.ServerFactory):
    protocol = FingerProtocol
    def __init__(self, **kwargs): self.users = kwargs
    def getUser(self, user):
        return defer.succeed(self.users.get(user, "No such user"))
application = service.Application('finger', uid=1, gid=1)
factory = FingerFactory(moshez='Happy and well')
r = internet.TCPServer(1079, factory)
r.setServiceParent(service.IServiceCollection(application))

# here is the command line:
#G:\Python23\Lib\site-packages\twisted\scripts\twistw.py  -ny
finger.tac -l c:\finger.log

As I stated no traceback and no output!
