    Cannot modify folder from Windows (SAMBA)

    So I've been trying to set up a home server. I have Ubuntu 11.04 32-bit server installed right now. I am interfacing with PuTTY and Webmin.

    I am trying to share files via Samba. I can connect to the server via my Win7 network, but when I attempt to edit/create any files I get an error, "Destination Folder Access Denies, You need permission to perform this action".

    I tried setting permissions on the user account I am connecting through (testuser) to 777, but still no luck.

    Here is my Conf

    Code:
    #
    # Sample configuration file for the Samba suite for Debian GNU/Linux.
    #
    #
    # 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 most of which 
    # are not shown in this example
    #
    # Some options that are often worth tuning have been included as
    # commented-out examples in this file.
    #  - When such options are commented with ";", the proposed setting
    #    differs from the default Samba behaviour
    #  - When commented with "#", the proposed setting is the default
    #    behaviour of Samba but the option is considered important
    #    enough to be mentioned here
    #
    # NOTE: Whenever you modify this file you should run the command
    # "testparm" to check that you have not made any basic syntactic 
    # errors. 
    # A well-established practice is to name the original file
    # "smb.conf.master" and create the "real" config file with
    # testparm -s smb.conf.master >smb.conf
    # This minimizes the size of the really used smb.conf file
    # which, according to the Samba Team, impacts performance
    # However, use this with caution if your smb.conf file contains nested
    # "include" statements. See Debian bug #483187 for a case
    # where using a master file is not a good idea.

    Re: Cannot modify folder from Windows (SAMBA)

    So is there a real user account called "testuser?" If not, there should be, or you should use a different account.

    Does "testuser" own the files in /home/remote/test ? If not, open a terminal window and type:

    sudo chown testuser:testuser -R /home/remote/test
    sudo chmod -R 777 /home/remote/test

    You should also set the Samba password for testuser with smbpasswd in a terminal, too.

    Note that you can also make this share a guest account (no password) and not need to have any user account, if you don't care about password-protecting them. Here's what you could use to do it that way:

    Code:
    [MyShare]
    comment = My Home Server
    path = /shares/myshare
    guest ok = yes
    public = yes
    writable = yes
    create mask = 0777
    directory mask = 0777
    force user = nobody
    force group = nogroup
    and then do this in a terminal:

    sudo chown -R nobody:nogroup /shares/myshare

    (assuming you have your share in /shares/myshare )

    Re: Cannot modify folder from Windows (SAMBA)

    The issue may have been that I used passwd instead of smbpasswd to set up the password for "testuser".

    I followed your steps up to and including smbpasswd and it began working.

    Thanks a lot for the help!


    ================================

    edit:

    Logging in from another computer in the same network I get this guy again, I thought I had finally fixed this? What the hell.
