[Samba] nmblookup of client using bcast address fails

[Brian Leonard]

Hi,

I've been trying unsuccessfully over the past couple of days to get my
windows machines to recognize my linux box. I've been working through
the troubleshooting guides I can't get the query of the client machine
to work using the broadcast address:

I have the following 3 machine network:


lifebook    SUSE    192.168.1.100
renegade    WXP     192.168.1.101
maverick    W2K     192.168.1.105

I believe the broadcast address of the windows machines are also
192.168.1.255, but how do I confirm this? A ping on the broadcast
address only hits the linux machine and the Linksys switch:

lifebook:/var/log/samba # ping -b 192.168.1.255
WARNING: pinging broadcast address

Shouldn't the ping also be hitting the windows machines?
