SAMBA Browsing and connecting problem

Distributor ID: Ubuntu
Description: Ubuntu 16.04.1 LTS
Release: 16.04
Codename: xenial

Installed SAMBA, as I am connecting to some Windows servers. I get this error “Failed to retrieve share list from server: Connection timed out” When trying to browse the network. Also running Mint, works perfectly on Mint. Why am I having this problem.

Sometimes the network computers doesn’t even populate when I browse the workgroup. smb://workgroup/ other times it does. Any changes i can make to smb.conf to fix this issue? Using Samba Server Configuration Tool 1.2.63 to manage samba shares and users. Smb.conf looks like this:

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

#================== Global Settings ==================


Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = linux

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


The specific set of interfaces / networks to bind to
This can be either the interface name or an IP address/netmask;
interface names are normally preferred
; interfaces = 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


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
through syslog you should set the following parameter to something higher.
syslog = 0

Do something sensible when Samba crashes: mail the admin a backtrace
panic action = /usr/share/samba/panic-action %d


Server role. Defines in which mode Samba will operate. Possible
values are “standalone server”, “member server”, “classic primary
domain controller”, “classic backup domain controller”, “active
directory domain controller”.

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.
; passdb backend = tdbsam

obey pam restrictions = yes

This boolean parameter controls whether Samba attempts to sync the Unix
password with the SMB password when the encrypted SMB password in the
passdb is changed.
unix password sync = yes

For Unix password sync to work on a Debian GNU/Linux system, the following
parameters must be set (thanks to Ian Kahan <[email protected] 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’.
pam password change = yes

This option controls how unsuccessful authentication attempts are mapped
to anonymous connections
map to guest = bad user


The following settings only takes effect if ‘server role = primary
classic domain controller’, ‘server role = backup domain controller’
or ‘domain logons’ is set

It specifies the location of the user’s
profile directory from the client point of view) The following
required a [profiles] share to be setup on the samba server (see
; logon path = \%N\profiles%U
Another common choice is storing the profile in the user’s home directory
(this is Samba’s default)
logon path = \%N%U\profile

The following setting only takes effect if ‘domain logons’ is set
It specifies the location of a user’s home directory (from the client
point of view)
; logon drive = H:
logon home = \%N%U

The following setting only takes effect if ‘domain logons’ is set
It specifies the script to run during logon. The script must be stored
in the [netlogon] share
NOTE: Must be store in ‘DOS’ file format convention
; logon script = logon.cmd

This allows Unix users to be created on the domain controller via the SAMR
RPC pipe. The example command creates a user account with a disabled Unix
password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos “” %u

This allows machine accounts to be created on the domain controller via the
SAMR RPC pipe.
The following assumes a “machines” group exists on the system
; add machine script = /usr/sbin/useradd -g machines -c “%u machine account” -d /var/lib/samba -s /bin/false %u

This allows Unix groups to be created on the domain controller via the SAMR
RPC pipe.
; add group script = /usr/sbin/addgroup --force-badname %g


Using the following line enables you to customise your configuration
on a per machine basis. The %m gets replaced with the netbios name
of the machine that is connecting
; include = /home/samba/etc/smb.conf.%m

Some defaults for winbind (make sure you’re not using the ranges
for something else.)
; idmap uid = 10000-20000
; idmap gid = 10000-20000
; template shell = /bin/bash

Setup usershare options to enable non-root users to share folders
with the net usershare command.

Maximum number of usershare. 0 (default) means that usershare is disabled.
; usershare max shares = 100

Allow users who’ve been granted usershare privileges to create
public shares, not just authenticated ones
usershare allow guests = yes
username map = /etc/samba/smbusers
security = user
; encrypt passwords = yes
; guest ok = no
; guest account = nobody

#================== Share Definitions ==================

Un-comment the following (and tweak the other settings below to suit)
to enable the default home directory shares. This will share each
user’s home directory as \server\username
; comment = Home Directories
; browseable = no

By default, the home directories are exported read-only. Change the
next parameter to ‘no’ if you want to be able to write to them.
; read only = yes

File creation mask is set to 0700 for security reasons. If you want to
create files with group=rw permissions, set next parameter to 0775.
; create mask = 0700

Directory creation mask is set to 0700 for security reasons. If you want to
create dirs. with group=rw permissions, set next parameter to 0775.
; directory mask = 0700

By default, \server\username shares can be connected to by anyone
with access to the samba server.
Un-comment the following parameter to make sure that only “username”
can connect to \server\username
This might need tweaking when using external authentication schemes
; valid users = %S

Un-comment the following and create the netlogon directory for Domain Logons
(you need to configure Samba to act as a domain controller too.)
; comment = Network Logon Service
; path = /home/samba/netlogon
; guest ok = yes
; read only = yes

Un-comment the following and create the profiles directory to store
users profiles (see the “logon path” option above)
(you need to configure Samba to act as a domain controller too.)
The path below should be writable by all users so that their
profile directory may be created the first time they log on
; comment = Users profiles
; path = /home/samba/profiles
; guest ok = no
; browseable = no
; create mask = 0600
; directory mask = 0700

comment = All Printers
browseable = no
path = /var/spool/samba
printable = yes
; guest ok = no
; read only = yes
create mask = 0700

Windows clients look for this share name as a source of downloadable
printer drivers

path = /home/wvb
writeable = yes
; browseable = yes
valid users = wvb

Im having the same issue with fresh install. I have a ubuntu 16.04 file server (just using for samba share files) and can connect just fine to the ubuntu file server from windows machines but cannot connect from ubuntu-mate computer. I have the default settings without any changes made.

I can see the workgroups, then the computers in the workgroups but when trying to connect to the ubuntu file server it shows:

Then after a long wait i get this:

Any help would be awesome...

Ok found this on the web and added it to smb.conf. Fixed the issue I was having with samba client. Added right under the [global] section.

client use spnego = no

Hope this helps someone else. :grinning:

Hi @van_bosch,

is there anything for you here?:

Thanks for all the info. I tried all recommendations, and could not get SAMBA going properly. I ended up installing Mint 18, and this resolved my issue. I needed a solution as I use my machine as a daily driver and SAMBA must work. Thanks however for all the feedback.

Will be good if Ubuntu Mate team can include SAMBA by default in future distros and make sure it works properly.
