Build Samba using centos

Samba is mainly used to share files or devices between Windows and Linux systems. It is a software package for sharing files and printing services between computers on the network. The protocol is the client service protocol, provided by a client similar to FTP Program The smbclient command of the client Samba program is generally used in the internal network.

Samba Overview

Introduction

Samba (SMB is SErver Message BlockIs a network server used for sharing files between Linux and Windows. samba can be used to share files between Windows and Linux. It is also used to share files between Linux and Linux. However, it provides a better network file system NFS for file sharing between Linux and Linux, NFS also requires server setup. we all know that each machine in the Windows network can be a file sharing server. samba works the same way. For example, if a Linux machine is installed with the Samba server, it can act as a shared server and can also be used as a client to Access Windows shared file systems in other networks, or other Linux sabmba servers. in Windows network, we can see the shared file function, we can directly use the shared folder as a local hard disk. in Linux, Samba is used to provide a shared file system to machines on the network. It can also be used to mount the sharing of other machines on the local machine. in a sense, this is different from ftp. Samba uses the NetBIOS protocol.

 

+ Personal understanding

1. Samba should be mainly used to share files or devices between Windows and Linux systems;
2. Samba is a software package for sharing files and printing services between computers on the network;
3. The Samba protocol is a client service protocol;
4. Samba provides a smbclient command for samba client programs similar to FTP client programs;
5. Samba is generally used in the internal network;
    

Daemon

Samba has two Daemon Processes: smbd and nmbd.

1. Smbd listens to port 139 TCP* Nmbd cannot be started if this process is not enabled, and smbd cannot start smbad.
2. Nmbd listening 137 and 138 UDP fracture* Nmbd is used only when smbd is not started.

    

Build Environment

Samba is installed on centos 5.5 by default,

However, my system is 5.6. By default, Samba is not installed, and the source code is installed.
