[SLUG] Strange behaviour of Samba3 with wireless clients

[Carlo Sogono <carlo.sogono@xxxxxxxxxxxxx>]

I have built my own wireless AP with Ubuntu 7.10 and an Atheros-based 
wireless card. My problem is that I can't access any of the Samba shares 
with my wireless clients...they can all search for the server, get 
prompted for a login then it just hangs and eventually times out.

The same clients, when using their LAN ports to connect to the same 
server are able to do everything. I have experimented with the smb.conf 
file to include the wireless AP's device (ath0), subnet and even 
allowing it to bind on all interfaces. During those times, samba *does* 
bind on the device/device's IP when doing 'netstat -tln'.

I have also checked my firewall settings. The rules I have for my local 
LAN on eth1 is identical to ath0 so I don't see a problem there. In fact 
I can do everything on my wireless clients except Samba.

Here are some details of my setup:
Ubuntu 7.10 server
eth0 - ADSL modem; running pppoe
eth1 - local LAN
ath0 - wireless LAN
madwifi drivers for Atheros chips
hostapd to handle WPA2+PSK authentication
iptables for IP filtering

Am I missing something here? Thanks in advance.
