Hello everyone,

I wrote a twisted app using the XMPP code that works fin on linux (and windows), but on Mac I get a twisted.names.error.DNSNameError, I searched google but found nothing on this, is there a known bug with Twisted on Mac?

I have Mac OS X 10.5.8, and the latest version of twisted from the website.

DNS is good at having behavior sensitive to the environment you are using it in. I'm not sure if there are any known bugs which would explain the problem you're encountering, mostly because I don't really know what problem you're encountering. ;) "twisted app using XMPP code" and "get a DNSNameError" don't say a whole lot. What API is failing? What other details can you provide? It may be a bug in Twisted, or it may be a configuration issue relating to your Mac host. Jean-Paul

Thank you, Gabriel

Here is some example code (from Twisted), this works as-is on linux but not on Mac. I tried an internal and an external XMPP server. On Mac I get this : python xmpp_client.py test@toto.com 123 2009/08/11 18:21 +0200 [-] Log opened. 2009/08/11 18:21 +0200 [-] Starting factory 2009/08/11 18:21 +0200 [-] /etc/resolv.conf changed, reparsing 2009/08/11 18:21 +0200 [-] Resolver added ('83.219.127.194', 53) to server list 2009/08/11 18:21 +0200 [-] Resolver added ('83.219.127.226', 53) to server list 2009/08/11 18:21 +0200 [-] twisted.names.dns.DNSDatagramProtocol starting on 49226 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] <__main__.XMPPClientConnector instance at 0x1003aa8> will retry in 2 seconds 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] Stopping factory 2009/08/11 18:21 +0200 [-] Starting factory 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] <__main__.XMPPClientConnector instance at 0x1003aa8> will retry in 7 seconds 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] Stopping factory 2009/08/11 18:21 +0200 [-] Starting factory 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] <__main__.XMPPClientConnector instance at 0x1003aa8> will retry in 14 seconds 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] Stopping factory 2009/08/11 18:21 +0200 [-] Starting factory 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] <__main__.XMPPClientConnector instance at 0x1003aa8> will retry in 30 seconds 2009/08/11 18:21 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] Stopping factory 2009/08/11 18:22 +0200 [-] Starting factory 2009/08/11 18:22 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] <__main__.XMPPClientConnector instance at 0x1003aa8> will retry in 83 seconds 2009/08/11 18:22 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] Stopping factory 2009/08/11 18:23 +0200 [-] Starting factory 2009/08/11 18:23 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] <__main__.XMPPClientConnector instance at 0x1003aa8> will retry in 241 seconds 2009/08/11 18:23 +0200 [twisted.names.dns.DNSDatagramProtocol (UDP)] Stopping factory ############################################################## # -*- coding: utf-8 -*- # Copyright (c) 2001-2006 Twisted Matrix Laboratories. # See LICENSE for details. import sys from twisted.internet import reactor from twisted.names.srvconnect import SRVConnector from twisted.words.xish import domish from twisted.words.protocols.jabber import xmlstream, client, jid from twisted.python import log log.startLogging(sys.stdout) class XMPPClientConnector(SRVConnector): def __init__(self, reactor, domain, factory): SRVConnector.__init__(self, reactor, 'xmpp-client', domain, factory) def pickServer(self): host, port = SRVConnector.pickServer(self) if not self.servers and not self.orderedServers: # no SRV record, fall back.. port = 5222 return host, port class Client(object): def __init__(self, client_jid, secret): f = client.XMPPClientFactory(client_jid, secret) f.addBootstrap(xmlstream.STREAM_CONNECTED_EVENT, self.connected) f.addBootstrap(xmlstream.STREAM_END_EVENT, self.disconnected) f.addBootstrap(xmlstream.STREAM_AUTHD_EVENT, self.authenticated) f.addBootstrap(xmlstream.INIT_FAILED_EVENT, self.init_failed) f.addBootstrap(xmlstream.STREAM_ERROR_EVENT, self.error) connector = XMPPClientConnector(reactor, "10.204.232.117", f) connector.connect() def rawDataIn(self, buf): print "RECV: %s" % unicode(buf, 'utf-8') def rawDataOut(self, buf): print "SEND: %s" % unicode(buf, 'utf-8') def connected(self, xs): print 'Connected.' self.xmlstream = xs # Log all traffic xs.rawDataInFn = self.rawDataIn xs.rawDataOutFn = self.rawDataOut def disconnected(self, xs): print 'Disconnected.' reactor.stop() def authenticated(self, xs): print "Authenticated." presence = domish.Element((None, 'presence')) xs.send(presence) def init_failed(self, failure): print "Initialization failed." print failure self.xmlstream.sendFooter() def error(self, failure): print "error" print failure self.xmlstream.sendFooter() client_jid = jid.JID(sys.argv[1]) secret = sys.argv[2] c = Client(client_jid, secret) reactor.run()
