I have several PI's with rasbian installed on it. When i try to ping an raspbian pi from another raspbian pi, i only get
ping: unknown host radio.local
When i do the same on my ubuntu, it works. When i ping raspbmc.local (another pi) from an raspbian pi, it also works:
PING raspbmc.local (192.168.0.17) 56(84) bytes of data.
64 bytes from raspbmc.local (192.168.0.17): icmp_req=1 ttl=64 time=9.52 ms
I have installed the package avahi-daemon on the radio pi.
Because i can ping the raspbmc.local, but not the radio.local, i guess there is a configuration issue on the radio.local.
