smb

sudo apt-get update
sudo apt-get install samba

mkdir /home/user/share/
sudo mousepad /etc/samba/smb.conf

At the bottom of the file, add the following lines:

[share]
comment = SMB share on user
path = /home/user/share/
read only = no
browsable = yes
writeable = yes
guest ok = no
public = no
valid users = smbuser1

sudo chmod -R 0755 /home/user/share/
sudo chown -R nobody:nogroup /home/user/share/

Create & modify users? for example «smbuser1»:

useradd smbuser1
passwd smbuser1

* These settings can be viewed or altered in the /etc/default/useradd file.
The useradd command will make changes to the /etc/passwd, /etc/shadow, /etc/group and /etc/gshadow files
see too https://linuxconfig.org/useradd

smbpasswd -a smbuser1
type&retype on screen password

* file /etc/passwd

for modify:
smbpasswd -a smbuser1
sudo smbpasswd -a smbuser1

for delete:
# smbpasswd -x smbuser1
then:
# userdel -r smbuser1

Username used must belong to a system account, else it won’t save.

Now that we have our new share configured, save it and restart Samba for it to take effect:

sudo service smbd restart

or For RHEL/CentOS 6:
service smb reload

For RHEL/CentOS 7:
systemctl reload smb

Update the firewall rules to allow Samba traffic:

sudo ufw allow samba

so:
sudo apt-get install ufw

Win:

\\ip-address\share

* cmd -> netstat

Linux & mac:

smb://ip-address/share

# ip addr — to view ip address
