Using a twisted pair cable or a switch should make no difference. How are you testing ?
zeroconf networking (aka bonjour) is basically 3 things: 1) automatically assigning an ip when no dhcp is available (169.254.0.0/16), this feature is also available on Windows, you can check that you have an ip like this with (ip addr or ifconfig in a shell) 2) resolving hostname when no dhcp is available using HOSTNAME.local (you can test using ping HOSTNAME.local, you work work with your hostname, and the hostname of other macosx / linux host) 3) discovering services on the network (eg: shared music by itunes), you can test by sharing some musics with itunes on your mac or with rhythmbox on linux, and the shared music should appear on the other mac/linux box you can also test by installing "avahi-utils" package and using "avahi-browse -a" from the shell, it will discover available host and services on your network -- Ubuntu offers no "zero configuration network" or so (unlike Apple) https://bugs.launchpad.net/bugs/146737 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
