Samba is a free software that implements the SMB protocol on Linux and UNIX systems and consists of server and client programs.SMB (Server Messages Block) is a communication protocol for sharing files and printers on a local area network. It provides file and printer sharing services between different computers in the local area network.The SMB protocol is a client/server protocol through which clients can access shared file systems, printers, and other resources on the server.By setting "NetBIOS over TCP/IP", Samba can share resources not only with local area network hosts, but also with computers around the world.

security = user
passdb backend = tdbsam
map to guest = bad user ##All anonymous users are named guest
[DATA] ##Name of data group
comment = weixin data
path = /westos
guest ok = yes ##Allow anonymous users to log on
; writable = yes ##File Writable
write list = @student ##Writable users in student group
browseable = no ##Hide directories but can be called
valid = student ##Callable User
2. On Client (172.25.254.89)

mount -o username=student,password=123//172.25.254.103/student/mnt/ ##Log on as a student user
df ##Check if mounting was successful
2. Permission Control
1. On the server side
mkdir /westos ##Add Directory
useradd westos ##New Users
smbpasswd -a westso ##Change Password
setfacl -m u :student:rwx /westos ##Read and write to user student
setfacl -m g :student:rwx /westos ##Read and write permissions to users of group student s
usermod -G student westos ##Set user westos group to student2. On the client side:
mount -o username=westos,password=(Password) //172.25.254.103/DATA /mnt
cd /mnt
touch fie{1..4} ##Test for Read and Write
rm -fr file13. Multi-user mounted on client superuser identity
yum install -y cifs-utils
vim /root/smbfile(Any file name)
> username=student
Password=lee
monut -o credentials=/root/smbfile,multiuser,sec=ntlmssp //172.25.254.103(Server)
cd /mnt
ls ##test
//Switch normal user test:
su - kiosk
df
cd /mnt/
ls ##Test, no files can be viewed normally, with permission restrictions
