Help with Samba
 
I need to create two shares. One share is read only accessible by anyone without a username and password. The second share is Read/Write accessible by only people with a username and password.

How do I go about doing this?

I have created both share successfully using "share" security permissions in samba, but when I try to access the Read/Write directory in Windows it only allows to me connect as Guest. I am unable to enter a different username.

When I tried to change the samba security to "user". The read-only directory is only accessible with a username and password.

Please advise.

Thanks!

Security should be set to 'user'. What do your share configurations look like? They will need the following options:

# Access allowed to everyone (read only)
[share1]
path = /some/location
browseable = yes
public = yes
writable = no

# Access allowed only to valid users

[share2]
path = /some/location
browseable = yes
writable = yes
valid users = user1 user2 user3 ...


After that you'll need to add passwords for the valid users using smbpasswd:

smbpasswd -a user1

Note: user1 has to exist in the /etc/passwd file before you can set the password for it with smbpasswd.

you can add in vfs function which allow user delete file into recycle bin (By default the deleted file will lost permanently).

SlackDaemon...

I have configured just as you stated... but when I try to access share1 (read-only) it is prompting me for username and password. I am trying to access from a Windows XP machine if it makes any difference.

Thanks

Here's the smb.conf file:

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.

In that case add the following line under the global section:

[Global]

null passwords = yes


Add the following to the read-only share:

guest ok
guest only
guest account = guestuser


Next add a guestuser account as follows:

useradd guestuser
smbpasswd -n -a guestuser

Save your changes then restart the samba server.
Note that windows will still prompt for a username and password. This is unavoidable. Simply use the guestuser account without specifying a password. On subsequent tries you will no longer be prompted for a username and password.

For some odd reason Windows requires the username. The <Ok> button will remain disabled until a single character is typed in to the username field. You'll notice that accessing the same share with smbclient //hostname/sharename -N will not prompt for a username or password at all.
