sudo apt-get install -y samba samba-common python-glade2 system-config-samba
sudo cp -pf /etc/samba/smb.conf /etc/samba/smb.conf.bak
sudo sh -c 'cat /dev/null  > /etc/samba/smb.conf'
sudo nano /etc/samba/smb.conf
sudo service smbd restart
testparm

sudo addgroup smbgrp
sudo useradd till -G smbgrp
sudo smbpasswd -a SOMEEXISTEDUSER
sudo mkdir -p /samba/secured
cd /samba
sudo chmod -R 0770 secured
sudo chown root:smbgrp secured
sudo nano /etc/samba/smb.conf

sudo netstat -pant | grep smbd   # mine shows 139 & 445
  • I have trouble to connect to the samba server though connecting it itself from the samba server works fine.

Use Dash and search for 'samba'. It will ask for the user's password first. The samba password can also be set by

sudo smbpasswd -a USERNAME

A non-gui way to configuration samba is adding the following to the end of /etc/samba/smb.conf file, sudo nano -w /etc/samba/smb.conf (-w means no-wrap). Any line beginning with a semicolon (“;”) or a hash (“#”) character is ignored.

[brb]
        path = /home/brb
;       writeable = no
;       browseable = yes
        guest ok = yes
  • (2020-04-27) Ubuntu 18.04. This is following the class "Building an Ubuntu Home Server" in lynda.com
    1. mkdir /mnt/stored/shared
    2. chmod 444 /mnt/storage/shared
    3. sudo apt install samba
    4. sudo nano /etc/samba/smb.conf. Scroll down to the bottom and add
    5. [fileshare]
        comment = share files
        path = /mnt/storage/shared
        readonly = yes
        create mask = 0444
        directory mask = 0444
      
    6. testparm
    7. sudo systemctl restart smbd
    8. sudo smbpasswd -a CurrUserName
    9. sudo useradd user2 # optional
    10. sudo passwd user2 # optional
    11. sudo smbpasswd -a user2 # optional
    12. sudo ufw allow 139/tcp
    13. sudo ufw allow 445/tcp

On Windows PC, go to start and open 'Run' then enter ip with double backslash. Like this (\\192.168.1.XX). On macOS/Linux, "Connect to Server" in the file browser, smb://192.168.1.XX/fileshare.
