Samba Server Installation on Debian 8 (Jessie)

Connect to your server on the shell as root user and install the Samba packages:
#apt-get install libcups2 samba samba-common cups

Move the current smb.conf file to smb.conf.bak:

mv /etc/samba/smb.conf /etc/samba/smb.conf.bak

And then create a new file smb.conf file:

nano /etc/samba/smb.conf

With the following content:

[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = debian
security = user
map to guest = bad user
dns proxy = no
#this setting for disable share printer error message
#like: Unable to connect to CUPS server localhost:631 - Bad file descriptor 
load printers = no
printing = bsd
printcap name = /dev/null
disable spoolss = yes
Replace WORKGROUP with the workgroup name that is used on your Windows clients. If you don't know the name of the workgroup, run this command on the Windows client to get the workgroup name:
net config workstation
Then close the Samba configuration file on the server and restart Samba:

#systemctl restart smbd.service

Adding Samba Shares

Now I will add a share that is accessible by all users.
Create the directory for sharing the files and change the group to the users group:

#mkdir -p /home/shares/allusers
#chown -R root:users /home/shares/allusers/
#chmod -R ug+rwx,o+rx-w /home/shares/allusers/

#mkdir -p /home/shares/anonymous
#chown -R root:users /home/shares/anonymous/
#chmod -R ug+rwx,o+rx-w /home/shares/anonymous/

At the end of the file /etc/samba/smb.conf add the following lines:

#nano /etc/samba/smb.conf

Group share

This is a share that is accessible and writable for all members of our "users" group. Add the following config at the end of the smb.conf file.
[allusers]
  comment = All Users
  path = /home/shares/allusers
  valid users = @users
  force group = users
  create mask = 0660
  directory mask = 0771
  writable = yes

Home directories

If you want all users to be able to read and write to their home directories via Samba, add the following lines to /etc/samba/smb.conf (make sure you comment out or remove the existing [homes] section):
[homes]
   comment = Home Directories
   browseable = no
   valid users = %S
   writable = yes
   create mask = 0700
   directory mask = 0700

Anonymous share

You like to have a share were all users in your network can write to? Be careful, this share is open to anyone in the network, so use this only in local networks. Add an anonymous share like this:
[anonymous]
   path = /home/shares/anonymous
   force group = users
   create mask = 0660
   directory mask = 0771
   browsable =yes
   writable = yes
   guest ok = yes
  

Now we restart Samba:
systemctl restart smbd.service

Adding and Managing Users
In this example, I will add a user named tom. You can add as many users as you need, in the same way, just replace the username tom with the desired username in the commands.

useradd tom -m -G users

Set a password for tom in the Linux system user database. If the user tom should not be able to log into the Linux system, skip this step.

passwd tom

-> Enter the password for the new user.
Now add the user to the Samba user database:

smbpasswd -a tom

-> Enter the password for the new user.

Now you should be able to log in from your Windows workstation with the file explorer (address is \\192.168.1.100 or \\192.168.1.100\tom fortom's home directory) using the username tom and the chosen password and store files on the Linux server either in tom's home directory or in the public shared directory.
