Samba Installation 24.04LTS

Install Samba and the required services.

apt install samba

Stop the samba service

 systemctl stop smbd.service

First we will create a samba user and set a password for Windows users to authenticate. If we want multiple users we can repeat this process.

adduser --disabled-login smbuser
adduser --disabled-login smbadmin
smbpasswd -a smbuser
smbpasswd -a smbadmin

Now we will create a group to assign to the various shares we are going to create for admin access (read write)

groupadd -g 10000 smbadmins

We now need to add the users into this group.

usermod -a -G smbadmins smbadmin

We can also add sysadmin to this group to give it samba RW permissions

usermod -a -G smbadmins sysadmin

Now we need to create the share directory and set its permissions.

chown -R smbadmin:smbadmins /path/to/your/share

Change the file permissions

chmod -R 2775 /path/to/your/share

This will set the group sticky bit so that new files / folder will inherit group permissions.

Modify smb.conf

sudo nano /etc/samba/smb.conf

You can run a testparm command to check the samba configuration.

testparm

Then restart the samba service.

systemctl start smbd.service
