What is samba in linux

In Linux, samba is an open source software based on the SMB protocol. It is a software that allows the Linux system to apply the Microsoft network communication protocol. The samba software can be used for file sharing between Windows and Linux, and for resource sharing between Linux and Linux.

#The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.

1. Overview of Samba

1. Introduction to samba

Samba is available on Linux and UNIX A free software that implements the SMB protocol on the system, consisting of server and client programs.

SMB is a communication protocol for sharing files and printers on a local area network. It provides sharing services for files, printers and other resources between different computers in the local area network.

The SMB protocol is a C/S type protocol through which clients can access shared file systems, printers and other resources on the server.

samba is a software that allows Linux systems to apply Microsoft network communication protocols. The biggest function of samba is that it can be used for direct file sharing and print sharing between Linux and windows systems. samba can be used for both windows. File sharing with Linux can also be used for resource sharing between Linux and Linux.

Samba service composition

1) SMB is the core startup service of samba. It is mainly responsible for establishing a dialogue between the Linux samba server and the samba client and verifying user identity. It also provides access to the file and printing system. Only when the SMB service is started can file sharing be realized and monitor the 139 TCP port.

2) The NMB service is responsible for resolution. It is similar to the function implemented by DNS. NMB can match the workgroup name shared by the Linux system with its IP. If the NMB service is not started, it can only be accessed through IP. Access shared files and listen on UDP ports 137 and 138.

Install samba service

yum -y install samba

Check the installation status

rpm -qa | grep samba

2. samba listening port

The service corresponding to the tcp port is the smbd service, which is used to provide shared access to files and printing resources in the server
• The service corresponding to the udp port is the nmbd service, which is used to provide resolution based on NetBIOS host names

3. samba process

4. samba user

//smbpasswd 命令：
    -a Sys_User     //添加系统用户为 samba 用户并为其设置密码
    -d              //禁用用户帐号
    -e              //启用用户帐号
    -x              //删除用户帐号
 
 
[root@localhost ~]# yum -y install samba-*
[root@localhost ~]# useradd tom
[root@localhost ~]# smbpasswd -a tom
New SMB password:
Retype new SMB password:
Added user tom.

• share is used to set up anonymous access, but the current version no longer supports share, but anonymous access can still be achieved. The configuration method has changed
• 6. samba configuration file

/etc/samba/smb.conf (main configuration File)

#测试配置文件是否有语法错误，以及显示最终生效的配置。使用 testparm 命令
[root@localhost ~]# testparm
