Samba service configuration in detail (anonymous, identity, aliases, access control, mount access)

Samba service configuration in detail

Samba is a free software implementation of the SMB protocol on UNIX and Linux systems, consists of server and client programs. SMB (Server Messages Block, service information block) is a communication protocol to share files and printers on the LAN, which provides a shared service resource files and printers among different computers within the LAN is. The SMB protocol is a client / server type protocol, clients can access the shared file systems on servers, printers and other resources through the protocol. By setting "NetBIOS over TCP / IP" not only allows Samba to share resources with local area network host, but also to share resources with the computer world.

Samba anonymous access to shared services

 [root@localhost ~]# yum install samba -y
[root@localhost ~]# cd /etc/samba/
[root@localhost samba]# ls
lmhosts  smb.conf  smb.conf.example
[root@localhost samba]# mv smb.conf smb.conf.bak
[root@localhost samba]# grep -v "#" smb.conf.bak > smb.conf 
[root@localhost samba]# vim smb.conf

[global]  ##全局
        workgroup = SAMBA
        security = user 

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw
        map to guest = Bad User ##添加此项，开启匿名用户访问

[myshare]   ##添加的share文件
                path=/opt/chen   ##路径
                public=yes   ##公共访问
                browseable=yes ##能够访问
                writable=yes  ##允许有写的权限
                create mask=0644  ##设置权限
                directory mask=0755

[root@localhost samba]# mkdir /opt/chen
[root@localhost samba]# chmod 777 /opt/chen/
[root@localhost samba]# systemctl stop firewalld.service 
[root@localhost samba]# setenforce 0
[root@localhost samba]# systemctl start smb.service 

Test anonymous access to win10

Linux server back to see our shared file access is anonymous

[root@localhost samba]# cd /opt/chen/
[root@localhost chen]# ls
CHEN.txt
[root@localhost chen]# ls -l
总用量 0
-rw-r--r--. 1 nobody nobody 0 11月 14 09:55 CHEN.txt

Authentication Samba share services

[root@localhost samba]# vim smb.conf

[global]  ##全局
        workgroup = SAMBA
        security = user 

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw
        map to guest = Bad User  ##把原来的匿名访问删掉
[test]
                path=/opt/test         ##共享文件目录路径
                browseable=yes     ##能够访问，将public项去除
                create mask=0644
                directory mask=0755
                valid users=zhangsan, lisi      ##允许访问的用户
                write list=zhangsan                ##允许写入的用户

[root@localhost samba]# useradd zhangsan  ##创建用户
[root@localhost samba]# useradd lisi
[root@localhost samba]# smbpasswd -a zhangsan ##给用户设置密码
New SMB password:
Retype new SMB password:
Added user zhangsan.
[root@localhost samba]# smbpasswd -a lisi
New SMB password:
Retype new SMB password:
Added user lisi.
[root@localhost samba]# pdbedit -L  ##列出smb用户列表
zhangsan:1001:
lisi:1002:
[root@localhost samba]# cd /opt/
[root@localhost opt]# mkdir test
[root@localhost opt]# ls
chen  rh  test
[root@localhost opt]# chmod 777 test/
[root@localhost opt]# systemctl restart smb.service 

Win10 to test the authentication access

Samba sharing service account name mapping, alias account login

[root@localhost ~]# cd /etc/samba/
[root@localhost samba]# vim smbusers    ##创建账户映射配置文件

zhangsan = t01 t02   ##别名t01 t02 密码还是zhangsan用户的密码

[root@localhost samba]# vim smb.conf   ##配置Samba配置文件

[global]
                workgroup = SAMBA
                security = user

                passdb backend = tdbsam

                printing = cups
                printcap name = cups
                load printers = yes
                cups options = raw
                username map = /etc/samba/smbusers    ##添加别名的配置文件路径

[root@localhost samba]# systemctl restart smb.service   ##重启

Access to win10 test alias

Samba sharing service access control list

[root@localhost ~]# cd /etc/samba/    ##切换到Samba配置文件目录
[root@localhost samba]# vim smb.conf    ##修改配置文件

[test]
    path=/opt/test
    browseable=yes
    create mask=0644
    directory mask=0755
    valid users=zhangsan, lisi
    write list=zhangsan
    hosts deny=192.168.13.0   ##添加拒绝192.168.13段访问test
[root@localhost samba]# systemctl restart smb.service   ##重启Samba服务

Win10 control access to the test

Directly through the Windows shared folders used to mount Linux

利用Linux访问Windows共享的文件
[root@localhost ~]# smbclient -L //192.168.100.99/share    ##访问共享 
Enter SAMBA\root's password:                               ##密码
将共享的文件挂载到Linux中，直接访问文件
[root@localhost ~]# mkdir -p /opt/share01   ##创建挂载点
[root@localhost ~]# mount.cifs //192.168.100.99/share /opt/share01   ##将共享文件夹挂载到挂载点
Password for root@//192.168.100.99/share:  
[root@localhost ~]# cd /opt/share01    ##切换到挂载点
[root@localhost share01]# ls
test.txt
[root@localhost share01]# cat test.txt    ##查看共享文件夹的文件内容
this is a test!!
