Mac OS X 10.4.3: Connecting to Unslung 4.20 through Samba 3.0.14a hangs Finder
When trying to mount Unslung disk through Samba using dialog screen, through Network->Workgroup->NSLU2 server and clicking the Connect button, the Finder application hangs.
and you should get your disk mounted in your Mac. It worked for me.
Thanks to Asko Kauppi for pointing me on the right direction!
