Hmm... strange.. I tried it with CentOS 5.2 and it worked..
I guess there is something wrong with my Samba configuration..
In my Opensuse 11.1, I could create and delete folder. But whenever I tried to copy some files, it will say no space left on device and if I click the details, it tells me "Permission Denied"..
How could I've been denied if I could create and delete the folder there.
Anyway, to access samba, usually I type "smb://192.168.1.x in the Nautilus address bar.
Thanks anyway, I'll try looking my smb config first.
:D
