- Samba can use the system user name but it doesn't use the system account password. That is, we need to set up a Samba password for our user account
- It is fine to use an existing directory to share

- What Ports Need To Be Open For Samba To Communicate With Other Windows/Linux Systems? Ans: 139 & 445.
- Share 'between' ubuntu and Windows
- Start and stop the samba daemons
$ ps -ef | grep smbd # see if the Samba daemon (smbd) $ ps -ef | grep nmbd # see if the NetBIOS name server daemon (nmbd) is running $ sudo service smbd stop # does not stop nmbd $ sudo service nmbd stop $ sudo service smbd start $ sudo service nmbd start
sudo apt-get install samba samba-common sudo apt-get install python-glade2 sudo apt-get install system-config-samba
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
- Share between ubuntu and linux On the client file manager, type smb://192.168.1.XX/
- https://help.ubuntu.com/community/Samba
- (2020-04-27) Ubuntu 18.04. (2022-03) Ubuntu 20.04. This is following the class "Building an Ubuntu Home Server" in lynda.com
- mkdir /mnt/stored/shared
- chmod 444 /mnt/storage/shared # optional
- sudo apt install samba
- sudo nano /etc/samba/smb.conf. Scroll down to the bottom and add
- testparm
- sudo systemctl restart smbd
- sudo smbpasswd -a CurrUserName (required)
- sudo useradd user2 # optional
- sudo passwd user2 # optional
- sudo smbpasswd -a user2 # optional
- sudo ufw allow 139/tcp # depends
- sudo ufw allow 445/tcp # depends
[fileshare] comment = share files path = /mnt/storage/shared readonly = yes create mask = 0444 directory mask = 0444
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.
Raspberry pi
How to Setup a Raspberry Pi Samba Server.
- 1) sudo apt update; sudo apt-get install samba samba-common-bin
- 2) mkdir /home/pi/shared
- 3) sudo nano /etc/samba/smb.conf
[pimylifeupshare] path = /home/pi/shared writeable=Yes create mask=0777 directory mask=0777 public=no
- “create mask” and “directory mask” – This option defines the maximum permissions for both files and folders. Setting this to 0777 allows users to read, write, and execute. Note when I create a new dir using mkdir, the permission is 755.
- 4) sudo smbpasswd -a pi # samba username/password
- 5) sudo systemctl restart smbd

create mask, directory mask, UMASK
- Understanding UMASK with Linux and Samba
- How to create a Samba share
- create mask = 0660: files in the share are created with permissions to allow all group users to read and write files created by other users.
- directory mask = 0770: as before, but for directories.
- This has nothing to do with Samba. This is related to file permissions.
Remove and re-install Samba
$ sudo apt-get remove --purge samba $ sudo apt-get remove --purge smbclient libsmbclient $ sudo apt-get install samba $ sudo apt-get install smbclient libsmbclient
SambaCry vulnerability and check Samba version
To check your samba version
$ smbd -V Version 4.3.11-Ubuntu
sudo mount -t cifs \ -o username=YOURUSERNAME,password=YOUPASSWORD \ //server_name_or_ip/shareName \ # shareName is different from a folderName /mnt/folder_to_mount_to/
Permission denied on soft-link folders
(Works on Ubuntu 22.04) How do you make samba follow symlink outside the shared path
[global] allow insecure wide links = yes [share] follow symlinks = yes wide links = yes
sudo service smbd restart
Example of /etc/samba/smb.conf
[global] workgroup = WORKGROUP server string = Samba Server %v netbios name = ubuntu security = user map to guest = bad user dns proxy = no logging = syslog@0 file allow insecure wide links = yes [share] comment = share files path = /home/XXX/Path1 readonly = yes # create mask = 0444 # directory mask = 0444 follow symlinks = yes wide links = yes [taichiVideo] comment = tai chi video path = /Path2/ read only = yes writable = no browsable = yes guest ok = yes
