    I have a Windows XP, and 2 Kubuntu systems linked together and a Xubuntu laptop. When I do not have the Xubuntu laptop connected I can see each Kubuntu system Samba shares from either or, I can get anything off the Windows XP system. I can not share files between the Kubuntu systems it will linkup open the hard drives but then it says 0 items (0 folders, 0 files). If I put the Xubuntu laptop in the loop I can share files from the Xubuntu to either of the Kubuntu sytems or from Xubuntu to XP but I can never transfer files from Kubuntu to Kubuntu.

    Does anyone have any idea what I need to do to be able to transfer files from the 2 Kubuntu systems? Thanks in advance.

    Do you see any errors in the logs on the Kubuntu systems?

    I'm sorry falko, I'm still a newbie please explain how I would check the logs in Kubuntu

    The log files are located in the /var/log directory. Open your file browser and go to that directory, and then open the files in a text editor.

    Samba problems

    Hello Falko,

    This is what I found in /var/log/samba folder log.adamsdaylocalhost which is the name of the Kubuntu system I am trying to connect with from linuxlocalhost the other Kubuntu system. When I checked the adamsdaylocalhost system log.linuxlocalhost I found the same error message

    [2009/01/21 19:57:29, 0] auth/auth_util.c:create_builtin_administrators(792)
    create_builtin_administrators: Failed to create Administrators
    [2009/01/21 19:57:29, 0] auth/auth_util.c:create_builtin_users(758)
    create_builtin_users: Failed to create Users

    This is the log.smbd

    [2009/01/21 20:07:40, 0] lib/util_sock.c:get_peer_addr(1224)
    getpeername failed. Error was Transport endpoint is not connected
    [2009/01/21 20:07:40, 0] lib/util_sock.c:get_peer_addr(1224)
    getpeername failed. Error was Transport endpoint is not connected

    Is there another log I should check?

    Thanks for the help

    Samba Problems

    Hey Falko,

    Sorry about being so long about getting back to you about this, my wife had serious surgery Monday along with some other health problems. Please find below the content of the netstat -tap and the smb.conf file

    Thanks again for the help.

    # 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
    # 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 commentary 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.

    Not a solution, but Security Issue in smb.conf

    I'm pretty new to all this as well, but in your smb.conf file, (someone correct me if I'm wrong) I don't think it's a good idea to have:

    invalid users = root
    in there. invalid users = guest or nobody, etc, but root?

    though root being what it is, would that give everyone not authenticated root access to the shares?
