Avahi: Problems with Name Resolution [Solved]

[mpuppe]

I have the following setup: two real machines (host1, host2) and a virtual machine (vm) running on host1. vm is attached to a bridged adapter. All hosts get their IP addresses via DHCP.

Here is my problem: Not all names get resolved on all machines. For example:

Code: Select all

mpuppe@host1 ~ $ ping host1.local
ping: unknown host host1.local
mpuppe@host1 ~ $ ping vm.local
ping: unknown host vm.local


But:

Code: Select all

mpuppe@vm ~ $ ping host1.local
64 bytes from host1.local (192.168.0.103): icmp_req=1 ttl=64 time=1.92 ms
64 bytes from host1.local (192.168.0.103): icmp_req=2 ttl=64 time=0.392 ms
...


I made a graph to visualize the situation. A->B means

Code: Select all

mpuppe@A ~ $ ping B.local


works correctly.



I hope someone here can help me

Edit:
nss-mdns was missing on host1 (Sabayon). The vm runs Debian which installs libnss-mdns automatically with avahi.
