    Setting up Samba in 14.04

    I need help setting up samba so that I can access my PC from my android devices.
    On Saucy I used this guide which worked perfectly http://www.maketecheasier.com/instal...r-file-sharing

    I'm currently using Trusty and it doesn't work now, I can't create shares. The only difference I've noticed in that guide is that it mentions "security = user" but that line is not in the smb.conf here and manually adding it doesn't seem to do anything.

    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. 
    
    #======================= Global Settings =======================
    
    [global]
    
    ## Browsing/Identification ###
    
    # Change this to the workgroup/NT-domain name your Samba server will part of
       workgroup = HOME-DESKTOP
    
    # server string is the equivalent of the NT Description field
    	server string = %h server (Samba, Ubuntu)
    
    # Windows Internet Name Serving Support Section:
    # WINS Support - Tells the NMBD component of Samba to enable its WINS Server
    #   wins support = no
    
    # WINS Server - Tells the NMBD components of Samba to be a WINS Client
    # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
    ;   wins server = w.x.y.z
    
    # This will prevent nmbd to search for NetBIOS names through DNS.
       dns proxy = no
    
    #### Networking ####

    # This can be either the interface name or an IP address/netmask;
    # interface names are normally preferred
    ;   interfaces = 127.0.0.0/8 eth0
    
    # Only bind to the named interfaces and/or networks; you must use the
    # 'interfaces' option above to use this.
    # It is recommended that you enable this feature if your Samba machine is
    # not protected by a firewall or is a firewall itself.  However, this
    # option cannot handle dynamic or non-broadcast interfaces correctly.
    ;   bind interfaces only = yes
    
    
    
    #### Debugging/Accounting ####
    
    # This tells Samba to use a separate log file for each machine
    # that connects
       log file = /var/log/samba/log.%m
    
    # Cap the size of the individual log files (in KiB).
       max log size = 1000
    
    # If you want Samba to only log through syslog then set the following
    # parameter to 'yes'.
    #   syslog only = no
    
    # We want Samba to log a minimum amount of information to syslog. Everything
    # should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log

    # Most people will want "standalone sever" or "member server".
    # Running as "active directory domain controller" will require first
    # running "samba-tool domain provision" to wipe databases and create a
    # new domain.
       server role = standalone server
    
    # If you are using encrypted passwords, Samba will need to know what
    # password database type you are using.

    # For Unix password sync to work on a Debian GNU/Linux system, the following
    # parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
    # sending the correct chat script for the passwd program in Debian Sarge).
       passwd program = /usr/bin/passwd %u
       passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
    
    # This boolean controls whether PAM will be used for password changes
    # when requested by an SMB client instead of the program listed in
    # 'passwd program'. The default is 'no'.

    For reference, looks like it was a bug in smb.conf https://bugs.launchpad.net/ubuntu/+s...a/+bug/1261873
    I've got it working by using the configuration file from Saucy.

    Re: Setting up Samba in 14.04

    I added this just above the #### Networking #### line of the 14.04 smb.conf

    Code:
    # What naming service and in what order should we use to resolve host names
    # to IP addresses
    name resolve order = lmhosts wins bcast host

    Re: Setting up Samba in 14.04

    I had to switch from "valid users = user1 user2 ..." to "username = user1, user2 ..." to get samba working on 14.04

    Re: Setting up Samba in 14.04

    I had a line
    valid users = %s

    I changed to
    username = %s

    Is this what your saying to do?

    That is what I did based on LY6n6fH's instructions above...and it's worked for me...I changed it in the global and specific share definitions...

    yes, that does work. I shared a folder in file manager.
    Then went to a windows PC (using google chrome desktop)
    And it shows up in the network.

    I suppose a good question is why it works?
    And why does 14.04 use 'valid users' which does not work?

    I have no clue but I've had the problem for a few months at least...my guess was something in the new smb.conf was the problem but I was thinking maybe password encryption...I would have never figured this out...it appears as if someone made a change without considering the entire downstream impact which makes one wonder about the Quality System that is in place.

    Re: Setting up Samba in 14.04

    It's not that "valid users" does not work. It's because of an incomplete removal of the original Debian [homes] share. From the bug report:
    In the "#======================= Share Definitions =======================" section of smb.conf exists the original [homes] share from Debian which looks like this but is scattered throughout the section:

    [homes]
    comment = Home Directories
    browseable = no
    read only = yes
    create mask = 0700
    directory mask = 0700
    valid users = %S

    Ubuntu usually comments out this share but in this case it was incomplete. Only [homes], "comment = Home Directories", and "browseable = no" were commented out.

    This leaves "read only = yes", "create mask = 0700", "directory mask = 0700" and "valid users = %S" intact and interpreted by samba as global parameters which makes a mess of things. In this particular bug report having "valid users = %S" interpreted as a global parameter induces the originally posted error message.
    All of the [homes] share parameters must be commented out.
