I used the example Browser to test the set-up.\n`from zeroconf import ServiceBrowser, Zeroconf\n\nclass MyListener(object):\n\n```\ndef remove_service(self, zeroconf, type, name):\n    print(\"Service %s removed\" % (name,))\n\ndef add_service(self, zeroconf, type, name):\n    info = zeroconf.get_service_info(type, name)\n    print(\"Service %s added, service info: %s\" % (name, info))\n```\n\nzeroconf = Zeroconf()\nlistener = MyListener()\nbrowser = ServiceBrowser(zeroconf, \"_tntsrv._tcp.local.\", listener)\ntry:\n    input(\"Press enter to exit...\\n\\n\")\nfinally:\n    zeroconf.close()`\nRunning from withing Ubuntu, it returns all the available services (as expected).\n\nI noticed that if I change `HOST_ONLY_NETWORK_MASK` from `255.255.255.255` to `255.255.255.0` the opposite happens, where it works under Windows but not under Ubuntu.\n\nThis seems to ocurr in line 1603\n`if addr.get('netmask') != HOST_ONLY_NETWORK_MASK`\n\nI'm not experienced enough to find a common ground, but is there any posibility so that it'll work under both systems?\n","author":{"url":"https://github.com/basic-settings","@type":"Person","name":"basic-settings"},"datePublished":"2016-09-28T11:26:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/84/python-zeroconf/issues/84"}
