    Unable to access Windows shares on an all Lucid network

    I marked this solved when I discovered, after much reconfiguring, I had a faulty Netgear router - I just thought I'd save you reading all this to find the answer. Cheers

    I have 3 machines at home all running Lucid. All have Samba and shared folders but I can't access files on any machine from any other. This worked ok when they were running Karmic. I'm also unable to set up printing across the network from the two machines without local printers. The main machine has 2 printers connected via USB, the others are using WiFi. I'm not using firewalls on any machine.

    Filesharing
    On any machine I go to Places, Network and Nautilus opens at network:/// and shows me 'Windows Network' I open that and see the Workgroup folder which I open and see the folder is empty. (I did see the 3 machines before I completely removed Samba and re-installed a few minutes ago)

    Printing
    On one of the remote machines I go to Add Printer, Select Device, Network Printer, Windows Printer via Samba, Browse but I can't see the machine with the printers attached in the Workgroup. Another clue is that when I look at the printer properties, policies on the main machine all 3 boxes are ticked, Enabled, Accepting jobs (but it says Not published) and Shared.

    Basically guys, the more things I try the worse it gets. Can someone put me right?

    Re: Unable to access Windows shares on an all Lucid network

    Pick one machine ... say the one with the printer ... and make sure the following services are running:
    Code:
    sudo service cups status
    sudo service nmbd status
    sudo service smbd status
    If any of them are not running start them:
    Code:
    sudo service cups start
    sudo service nmbd start
    sudo service smbd start
    Check to see if anything has changed and if not post the output of the following commands:
    Code:
    smbtree
    Code:
    net usershare info
    Code:
    testparm -s

    please post the output of the following commands:
    Code:
    cat /etc/samba/smb.conf
    
    
    nmblookup -A 192.168.1.0/24 # assuming your gateway is 192.168.1.1, adjust appropriately
    
    smbclient -L {one of the hostnames from previous command} -I {that machine's ip}

    d3v1150m471c,
    Some for you too. How do I go about finding gateways and IPs?

    oy@HPdc7700:~$ cat /etc/samba/smb.conf
    #
    # 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: Unable to access Windows shares on an all Lucid network

    [1] Well, for one thing you have no shares defined.

    "net usershare info" would have told us how your usershares or nautilus-shares are defined and the output os null. And testparm -s would have told us if you have any classic shares and there aren't any of those either.

    [2] If you're going to use Samba as pass-through to cups you need to make a modification of your smb.conf:
    [printers]
    comment = All Printers
    browseable = no
    path = /var/spool/samba
    printable = yes
    guest ok = yes
    read only = yes
    create mask = 0700
    [3] Your machine name is too long
    \\DELL-INSPIRON-L Dell-Inspiron-Laptop server (Samba, Ubuntu)
    cli_start_connection: failed to connect to DELL-INSPIRON-L<20> (0.0.0.0). Error NT_STATUS_UNSUCCESSFUL
    By default samba will use the hostname to anounce itself to the network but it has to be less than or equal to 15 characters in length.

    The fastest way to fix this is to add a line to the [global] section of smb.conf:
    Code:
    netbios name = Dell-Laptop
    It doesn't have to be that exact name but make it <= 15 characters in length.
    EDIT: Sorry, I should have been clearer about where to make that change. It should be none on Dell-Inspiron-Laptop's smb.conf not on HPdc7700.

    Then restart samba:
    Code:
    sudo service smbd restart

    Re: Unable to access Windows shares on an all Lucid network

    There are two things from your output that I just can't figure out:

    [1] "net usershare" and testparm show no shares yet smbtree show this:
    \\HPDC7700\shared
    Is that by any chance the printer? Or did you create a nautilus-share as root. If you do the following command do you get an output:
    Code:
    sudo net usershare info
    [2] testparm error:
    Global parameter usershare allow guests found in service section!
    For the life of me the only reference to it in your smb.conf is where it should be.

    Re: Unable to access Windows shares on an all Lucid network

    Code:
    ifconfig # will tell you your ip
    your router's ip address is your gateway. don't mistake this for your modem. if you don't know your router's ip you can right-click your network tray icon and go into connection information (while connected) and it will be your "default route". it'll probably be something like 192.168.1.1

    please see my responses on this thread as it may tell you what you need to know.

    http://ubuntuforums.org/showthread.php?p=10022515#post10022515


    it contains my additions to smb.conf (that file is otherwise not modified) and I touched on nautilus-share as well. i use my firewall to manage my samba security because it's easier especially with the dhcp on my network and sometimes the windows machines i share with have a myocardial infarction when they've encountered my samba security in the past.
