In Windows it asks for username & password & in Ubuntu it asks for username, domain & password.

I entered root's and local user's password it says NOT ACCESSIBLE.

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


## Browsing/Identification ###

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

# What naming service and in what order should we use to resolve host names
# to IP addresses

#### Networking ####

# 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

#### Debugging/Accounting ####

# that connects

# 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.

# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

  • Accessing Samba shares requires that you authenticate to the machine hosting the share with credentials for the sharing host, not the client accessing it. Have you tried authenticating with the username/password combo for the share host?

  • Cant understand "authenticating with the username/password combo for the share host?" please can you be more specific... Jan 4 '14 at 3:50
  • To access the Samba share, you have to use a username and password pair that exist on the machine that the share sits on (the host). It looks like you posted your Samba config file - are you trying to access a share on your Ubuntu machine, or a share on Windows machine?

  • i can access both windows and ubuntu shares but when i try to access my ubuntu pc from any other windows or ubuntu pc it asks for username and password. Jan 4 '14 at 5:58
  • That is how it should be. Now that we clearly understand what's going on, we can work towards a solution. I'll work on posting an answer for you shortly.

First make sure you are a root user so open up terminal and type. note this is for my server yours will use a different names but the actions will be the same.

geoff*testserver:-$ sudo passwd root
 [sudo] password for geoff:
 Enter new unix password:
 Retype new unix password:
 passwd: password updated successfully

ok you can now take control as a root user next. now you need to give the server a static ip address so type in

geoff*testserver:-$ su

root*testserver:/home/geoff* ifconfig         (this will show all the nics)

so take note of the bcast number and the netmask number now we will setup the static ip address.

root*testserver:/home/geoff* vi /etc/network/interfaces

you will now look for the line iface eth0 inet dchp

press INSERT on your keyboard and change dchp to static then add the details so your script will look like this.

iface eth0 inet static

when you have finished press escape the type :wq this will write and save the script. now you will restart the network type in

root*testserver: /home/geoff* /etc/init.d/networking restart

now see if all is well by doing an update so type

root*testserver: /home/geoff* apt-get update

you should see lots of lines of data scroll the screen this will confirm you configured the network and you can receive updates. if you only get errors you need to go back and fix it try different gateway. ok all good so far. next install

root*testserver: /home/geoff* apt-get install openssh-server samba smbclient cifs-utils ntp ntpdate

click y for the install now we will create the shared directories

root*testserver:/home/geoff* cd
 root*testserver:# mkdir /files

now we can make our folders i will make two

root*testserver:# mkdir /files/public
root=testserver:# mkdir /files/geoff

now we make them useable so type in

 root*testserver:# chmod 777 /files/public
 root=testserver:# chmod 777 /files/geoff

do this for every folder you make

so the next part we will edit samba this is important so take care

root*testserver:# vi /etc/samba/smb.conf

you will now be in the samba configuration file when we have done the edits your files will be on you network to everyone.

scroll down to workgroup setting and edit this to your network name this is important to windows machines , I have set mine to BLACKBIRD

dont forget to press INSERT on your keyboard so you can edit the files. ok scroll down and remove the hash tag from " wins support " and change the value from no to yes.

scroll down and remove the semi colon from "resolve name order"

scroll down and remove the hash tag from "security = user"

then scroll down again all the way to the bottom till you cant go any further then type in the following so we can enable the share folders

[ Geoff's files]
 comment = Geoff's files
 path = /files/geoff
 browseable = yes
 read only = no
[ Public files]
 comment = Public files
 path = /files/public
 browseable = yes
 read only = no

now hit the escape key on your keyboard the type :wq this will write and save your edit.

now we will add a samba password some computers will ask for this so,,

root*testserver:# smbpasswd -a geoff
 New SMB password
 Retype new SMB password:

Ok all is now complete restart your server your folder will be visible to all on your network , please note this is LINUX where spaces and uppercase and lowercase matters good luck..

  • OKzz i can access those folders from ubuntu machine but i can't access them from windows pc Jan 6 '14 at 12:04

    I realise it's an old thread I'm commenting on here but Ubuntu comes without a root password set to increase security and by setting one, especially as part of an answer for something totally different, you're decreasing security. A better way to switch to a root shell is to run sudo su.

I had to add a Samba password for my user before I could enter and access any shares the PC advertised:

smbpasswd -a [username]

Even though you've set security = user, by default Samba doesn't check against your system password file.


Looking at your smb.confentry, the first thing that jumps out at me is in the Domains section where you have:

    domain logons = yes
    domain master = yes
;   local master = yes
    preferred master = yes
    os level = 64

which indicates that you have configured Samba to act as a Primary Domain Controller (PDC). Unless you are running a group of Windows computers which need resource controls (very unlikely), this is not needed. You can disable that function by inserting a semi-colon ; at the start of each line I listed, just like one is already there for ; local master = yes. You will need to edit the file with sudo privileges by opening a Terminal session and using sudo pico /etc/samba/smb.conf. (I prefer pico for most of my command line text editing, but you can use the editor of your liking.) Once you make and save the changes, issue sudo service samba restart to have Samba restart and load the changed configuration.

  • ok now i am accessing shared folder from windows and it ask for username and password then i have to create users in ubuntu and give him smbpassword?? Jan 6 '14 at 6:47
  • @BishwanathDas If you have a user account on the Ubuntu machine besides root enter that username and password pair to access the share.

  • Using the same not working... it says \\share1 is not accessible contact system administrator (in windows) Jan 8 '14 at 6:04

If your SMB server is old (e.g. case Win Server 2003) and your Ubuntu is new enough (18), you might have to add vers=1.0 to the mount option. I upgraded from Ubuntu 16 to 18 and found my old SMB shares wouldn't mount without explicitly adding that mount option.
