https://bugs.winehq.org/show_bug.cgi?id=37271 Bug ID: 37271 Summary: Applications get IP address of 127.12.34.56 when lo0 is up Product: Wine Version: 1.7.26 Hardware: x86-64 OS: Mac OS X Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: jere(a)krischel.org My testing is specifically with Artemis 2.1.1, but it seems to be true for other applications as well. When running Artemis 2.1.1 under a standard OSX Mavericks 10.9.4 install, the application reports an IP address of 127.12.34.56. If I specifically shut down the loopback interface (lo0), it reports the IP address of the box properly (192.168.1.104). This behavior is *not* seen on Ubuntu 14.04.1, which has a loopback interface, but seems to prioritize it differently than OSX. I checked the routing table before and after shutting down the loopback interface, and this is the line that disappears on OSX after lo0 is down: Destination Gateway Flags Refs Use Netif Expire localhost localhost UH 0 0 lo0 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
