1st of all, IMHO, if Volnei is having a permissions problem, and he is
instead getting the I/O error message he mentioned in his 1st email,
then that is a bug.

>From the manpage (4.1.6):
public
This parameter is a synonym for guest ok.
guest ok (S)
If this parameter is yes for a service, then no password is
required to connect to the service. Privileges will be those of the
guest account.
This parameter nullifies the benefits of setting restrict
anonymous = 2
See the section below on security for more information
about this option.
Default: guest ok = no
guest ok / public does not grant any particular level of privileges to
the samba guest account. The samba guest account is still mapped to
the UNIX "nobody" account by default. (see the manpage entry for
"guest account"). "force user = root" overrides that mapping.
Similarly, "writable" does not imply that every user account that can
access the share can write to it. It means that they can write to it
if they have write permissions. "writable" is simply a way of making
the entire share read-only or not read-only. Either way, users can
only read from it if they have read (and execute) permissions. IMHO,
now that "security = share" has been removed from samba, "writable"
should default to "yes".
It sounds like the following is the problem/solution:
1. You need to give write permissions on the root dir to either the
guest account mapped user ("nobody" by default), or to all users.
2. You need to set the following so that guests can write to newly
created subdirs:
directory mask = 777
The manpage on "create mask" states: This parameter does not affect
directory masks. See the parameter "directory mask" for details.
Let us know if this works,
