[Twisted-Python] How can I call internet.MulticastServer() to enable listenMultiple?

I am refactoring and repacking all the ZeroConf / MulticastDNS stuff I have seen and been re-writing to be a "Service" I want to be able to start it from a .tac file. I can't find any documenation of explict example of how to start it using internet.MulticastServer() here is what I am trying <snip imports and other housekeeping code> zc = zeroconf.DebugZeroConfService() serviceCollection = service.IServiceCollection(application) internet.MulticastServer(5353, zeroconf.IZeroConfFactory(zc)).setServiceParent(serviceCollection) when I do this I get the 2005/04/01 13:25 EST [-] twisted.internet.error.CannotListenError: Couldn't listen on any:5353: (48, 'Address already in use'). I tried internet.MulticastServer(5353, zeroconf.IZeroConfFactory(zc), listenMultiple=True).setServiceParent(serviceCollection) but that throws this error 2005/04/01 13:26 EST [-] AttributeError: ZeroConfFactoryFromService instance has no attribute 'makeConnection' I have 4 TCP services running this way and I copied the Echo stuff pretty directly ( see the naming convention even ) can someone tell me what the correct syntax / idiom should be? -- If you don't know what you want, you probably need a nap.

[Twisted-Python] ANN: Twisted Trial v3.0 / Twisted VFS v0.1
by Christopher Armstrong 01 Apr '05

01 Apr '05

Hi Twisted, One of the key problems that trial solves is the traversal of Python modules and files, which is duplicated in at least two places in Twisted: Twisted Conch's SFTP, Twisted Core's FTP, and Twisted Web's Resource model. Creating a unified resource hierarchy in Twisted has long been a goal of the Twisted team, and every attempt has been mostly a failure. At the Australian Twisted Sprint, we've recently come to the realization that trial effectively already does this! So today we're starting to implement a new VFS system that unifies all of these systems into a single twisted.vfs module. This will enable things such as more secure remote file system access, a better internal design of Trial, and remote access to your unit tests. Some other things we plan to do: * 3d visualisation of any vfs implementation. * Run trial on any VFS implementation. Just have it serve Python code! * Any VFS-using protocol should be able to access your unit tests and run them. Just hit http://localhost/twisted/trial/test and it'll recursively run all the tests in twisted.trial.test. * Integration with Imagination. We'll be making heavy use of Facets in these new features. Keep your eyes peeled for code arriving in Twisted trunk in the next few days. -- Twisted | Christopher Armstrong: International Man of Twistery Radix | -- http://radix.twistedmatrix.com | Release Manager, Twisted Project \\\V/// | -- http://twistedmatrix.com |o O| | Founding Member, Hobart Hacking Society w----v----w-+ -- http://hackingsociety.org/chapters/hash

Maybe getTimeoutCancelFunction()? Jp

It's called Ni!Mail (http://www.nimail.org), and it's based on Twisted/Nevow. It's really at is early stage (I've just released a version 0.1 which is very basic), and I didn't intend to advertize on it so soon, but I've got a strong motivation to improve it. If you want to see what it looks like for now, you can go here: http://www.nimail.org/demo/ (login : demo(a)nimail.org, pass : demo). I would enjoy to see what you think of it. -- Thomas Herve [sorry for my basic english]
