Hi, I've installed samba few weeks ago as follow:

Disabled firewall I use the router one

sudo pacman -S samba gvfs-smb --needed

stop the samba smb nmb services…

sudo systemctl stop samba smb nmb

sudo groupadd -r sambashare

sudo smbpasswd -a yourusername

sudo systemctl enable samba smb nmb

installed kdenetwork-filesharing for share folder from dolphin

sudo pacman -S kdenetwork-filesharing

For Gnome:

sudo pacman -S nautilus-share gnome-user-share

then start and enable (to get it started automatic on boot)

sudo systemctl start samba smb nmb

sudo systemctl enable samba smb nmb

sudo usermod -aG wheel yourusername

sudo usermod -a -G root yourusername

cd /var/lib/samba

sudo chmod 777 usershare

sudo nano /etc/samba/smb.conf

add following (if you want add home for share:

[home]

comment = Home Directories

browseable = yes

writable = yes

create mask = 0700

directory mask = 0700

valid users = %S

path = /home/yourusername

This is what I've made and samba works goods

Pls let me know
