Samba

https://ubuntu.com/tutorials/install-and-configure-samba#1-overview

sudo apt update
sudo apt install samba

Add the following lines into this file /etc/samba/smb.conf replace values as you wish

[sambashare]
    comment = Samba on Ubuntu
    path = /home/username/sambashare
    read only = no
    browsable = yes

restart the service

sudo service smbd restart

Update the firewall rules to allow Samba traffic

sudo ufw allow samba

Since Samba doesn’t use the system account password, we need to set up a Samba password for our user account Username used must belong to a system account, else it won’t save.

sudo smbpasswd -a username
