[Samba] Problems getting list of shares

[Steve Gehrman]

I'm trying to do something that should be simple, but my current  
solution isn't working 100%

All I need is a list of smb shares on the network.

I'm doing this:

/usr/bin/nmblookup -M -- -

and then use this on each ip returned:

/usr/bin/smbclient -g -p 139 -NL <ip addr>

That works for most cases but it fails to find all the shares  
(compared to the mac Finder)
