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
Apparently that doesnt work anymore, and I havent had time to figure out the
new way. I think smbclient isn't even part of Samab3 (it could find it
after installing it).
