---

Install samba using distro’s package manager. Enable in systemctl.

sudo dnf install samba
sudo systemctl enable smb --now

Setup Firewall

• Create a UFW application profile for Samba at /etc/ufw/applications.d/samba

[Samba]

• Enable Samba traffic from selected subnets.

sudo ufw allow from $SUBNET to any app Samba

Setup Samba User

sudo smbpasswd -a $USER

Create and Designate a Directory to Share

mkdir ~/share
# SELinux rules. Replace "jack" with the name of your user
sudo semanage fcontext --add --type "samba_share_t" "/home/jack/share(/.*)?"
sudo restorecon -R ~/share

Update /etc/samba/smb.conf

Note: update /home/jack/share as necessary.

[share]
        comment = My Share
        path = /home/jack/share
        writeable = yes
        browseable = yes
        public = yes
        create mask = 0644
        directory mask = 0755
        write list = user

Restart Samba Service

sudo systemctl restart smb

Mounting the Share with Permissions

sudo mount -t cifs \
-o username=${USER},password=${PASSWORD},uid=$(id -u),gid=$(id -g) \
//server-address/sharename \
/mount/path/on/machine

Mounting the Share Automatically with /etc/fstab

• Create a credentials file for the Samba share in ~/.smb

user=myuser
password=mypassword
domain=WORKGROUP

• Create a backup of /etc/fstab

sudo cp /etc/fstab /etc/fstab.bak

• Append the following to /etc/fstab

//ip/sharename/ /mount/path cifs    credentials=/home/myuser/.smb,uid=userid,gid=groupid 0 0

• Apply the changes to /etc/fstab

sudo systemctl daemon-reload
sudo mount -a
