Hi
Starting twistd xmpp-router and trying to connect to it with a component
from the wokkel examples
"""
An XMPP Ping server as an external server-side component.
This ping server assumes the domain C{'ping'}.
"""
import sys
from twisted.python import log
from twisted.application import app, service, internet
from twisted.internet import reactor
from wokkel import component
from wokkel.ping import PingHandler
# Configuration parameters
EXT_HOST = 'localhost'
EXT_PORT = 5347
SECRET = 'secret'
DOMAIN = 'ping'
LOG_TRAFFIC = True
# Set up the Twisted application
application = service.Application("Ping Component")
router = component.Router()
pingComponent = component.Component(EXT_HOST, EXT_PORT, DOMAIN, SECRET)
pingComponent.logTraffic = LOG_TRAFFIC
pingComponent.setServiceParent(application)
pingHandler = PingHandler()
pingHandler.setHandlerParent(pingComponent)
produces the following traceback:

After some fiddling around it seems that the code at line 282 in
twisted\words\protocols\jabber\xmlstream.py presets the sid of the
stream to a str instead of a unicode(str). After changing line 282
from
self.xmlstream.sid = randbytes.secureRandom(8).encode('hex')
to
self.xmlstream.sid = unicode(randbytes.secureRandom(8).encode('hex'))
everything works as advertised.
Is there somebody around who could tell me what to do with this fix, I'm
certainly a beginner diddling with XMPP.
Thanks a bunch, Werner
