When I test diald, I find that in most situation link come up on requests
of the netbios (you have samba installed?). Standart filter of the diald
ignore netbios-ns packets (137 TCP port, in diald-config versions you
must put number of the NETBIOS_NS_TIMEOUT, without this diald will accept 
any netbios requests). But I find that diald accept every 10-15 min
requests like 192.168.1.254,138 (port 138) (netbios-dgn in /etc/services).
To check it - turn debug level in diald.conf to see filtering results. Any
way you will find which computer on which port starting connection and put
this to diald filter.
