I can try that. I'm not sure how to use Samba3, though. I was trying to help a friend use Samba, but I was use to Sama2, and Samba3 apparently recquires a smb.conf file. You use to be able to just do everything from the command line, like (I think): smbclient //server/share /mnt/pnt -o username=3D<username>,password=3D<password> Apparently that doesnt work anymore, and I havent had time to figure out th= e new way. I think smbclient isn't even part of Samab3 (it could find it after installing it).
