Installing Nautilus File Sharing Plugin on Ubuntu 24.04 LTS

To enable the Nautilus Samba/CIFS file-sharing feature, you must install the Nautilus file-sharing plugin on Ubuntu 24.04 LTS.

First, update the APT package database cache with the following command:

$ sudo apt update






To install the Nautilus file-sharing plugin on Ubuntu 24.04 LTS, run the following command:

To confirm the installation, press Y and then press .





The Nautilus file-sharing plugin is being installed on Ubuntu 24.04 LTS. It will take a while to complete.





At this point, the Nautilus file-sharing plugin should be installed.









Adding the Ubuntu Login User to the sambashare Group

Once the Nautilus file-sharing plugin is installed, you must add the login user of your Ubuntu system to the sambashare group. Otherwise, you won’t be able to share any directory/folder of your Ubuntu system using the Nautilus file-sharing plugin.

To add the login user of your Ubuntu system to the sambashare group, run the following command:

$ sudo usermod -aG sambashare $(whoami)




For the changes to take effect, reboot your Ubuntu system.

$ sudo reboot








Setting a Samba Share Password for the Login User of Ubuntu

You must also set a samba share password for the login user of your Ubuntu system to access the shared directories/folders from other devices.

To set a samba share password for the Ubuntu login user, run the following command:

$ sudo smbpasswd -a $(whoami)




Type in a samba share password for the Ubuntu login user and press .





Retype the samba share password for the Ubuntu login user and press .





A samba share password should be set for the Ubuntu login user.









Sharing a Directory with Nautilus File Manager on Ubuntu 24.04 LTS

To share a directory/folder with the Nautilus file manager on Ubuntu 24.04 LTS, right-click (RMB) on the directory/folder and click on Sharing Options.





To share the directory/folder, tick Share this folder.





You will find a few sharing options:

Share name^[1]: The default share name should be the name of the directory/folder being shared. You can also set a custom name for the share.

Comment^[2]: An optional short description of the share.

Allow others to create and delete files in this folder^[3] and Guest access^[4]: If you want to allow everyone (without needing to enter a correct username/password) full access (read+write) to this share, tick both of these options. If you want to allow everyone read access to this share, only tick Guest access^[4].

Once you’re done configuring the share options, click on Create Share^[5].





Once the directory/folder is shared, you will see a green indicator in the directory/folder as marked in the screenshot below.









Finding the IP Address of Ubuntu

To access the Samba/CIFS share from other devices, you must know the domain name or IP address of your Ubuntu 24.04 LTS system.

To find the IP address of your Ubuntu system, run the following command:

$ hostname -I




The IP address of your Ubuntu system should be printed.

In my case, the IP address of my Ubuntu system is 10.10.10.111.









Accessing the Samba/CIFS Share from Other Linux Devices

To access a Samba/CIFS share from other Linux devices, you need to access the share URL from the file manager in the following format:

smb:///




Here, is the domain name or IP address of the Samba/CIFS server and is the name of the Samba/CIFS share you want to access.

For example, to access the Samba/CIFS share MyShare from the Samba/CIFS server (my Ubuntu system) with the IP address 10.10.10.111, you will need to access the share URL smb://10.10.10.111/MyShare from the file manager of your Linux distribution^[1].

Once you attempt to access the Samba/CIFS share, you will be prompted for the username and password. Type in the login username and password^[2] and click on OK^[4].

If you want the file manager to remember the login username and password of the Samba/CIFS share so that you won’t have to type in the username and password in the future, make sure to tick Remember password^[3]before clicking on OK^[4].





You should be able to access the Samba/CIFS share and all the shared files.









Accessing the Samba/CIFS Share from Windows 10/11

To access a Samba/CIFS share from Windows 10/11, you need to access the share path from the File Explorer in the following format:

\\\




Here, is the domain name or IP address of the Samba/CIFS server and is the name of the Samba/CIFS share you want to access.

For example, to access the Samba/CIFS share MyShare from the Samba/CIFS server (my Ubuntu system) with the IP address 10.10.10.111, you will need to access the path \\10.10.10.111\MyShare from the File Explorer of your Windows 10/11 system^[1].

Once you attempt to access the Samba/CIFS share, you will be prompted for the username and password. Type in the login username and password^[2] and click on OK^[4].

If you want Windows 10/11 to remember the login username and password of the Samba/CIFS share so that you won’t have to type in the username and password in the future, make sure to tick Remember my credentials^[3]before clicking on OK^[4].





You should be able to access the Samba/CIFS share and all the shared files.
