ubuntu에서 무선랜 연결 후 이상한 메세지가 나온다면 이렇게 해보세요

Every time at boot I get a message “Network service discovery disabled. You current network has a .local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled.”

To disable it, you must edit the file /etc/default/avahi-daemon as root:

sudo -i
gedit /etc/default/avahi-daemon

and add this line (or change it if already exists to):

AVAHI_DAEMON_DETECT_LOCAL=0
