Samba - allows Linux to transfer files with Windows clients

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
# password protected
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 service smbd restart 

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.

        path = /home/brb
;       writeable = no
;       browseable = yes
        guest ok = yes
  • (2020-04-27) Ubuntu 18.04. (2022-03) Ubuntu 20.04. This is following the class "Building an Ubuntu Home Server" in
    1. mkdir /mnt/stored/shared
    2. chmod 444 /mnt/storage/shared # optional
    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 (required)
    9. sudo useradd user2 # optional
    10. sudo passwd user2 # optional
    11. sudo smbpasswd -a user2 # optional
    12. sudo ufw allow 139/tcp # depends
    13. sudo ufw allow 445/tcp # depends

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.

On Android, FE explorer, click "+". Enter Display Name, Host Name IP, Path, Port 445, User Name/PW. Save. It works.

Permission denied on soft-link folders

(Works on Ubuntu 22.04) How do you make samba follow symlink outside the shared path

allow insecure wide links = yes

follow symlinks = yes
wide links = yes
sudo service smbd restart

Example of /etc/samba/smb.conf

workgroup = WORKGROUP
server string = Samba Server %v
netbios name = ubuntu
security = user
map to guest = bad user
dns proxy = no
logging = [email protected] file
allow insecure wide links = yes

comment = share files
path = /home/XXX/Path1
readonly = yes
# create mask = 0444
# directory mask = 0444
follow symlinks = yes
wide links = yes

comment = tai chi video
path = /Path2/
read only = yes
writable = no
browsable = yes
guest ok = yes
