SMB (server message block) Service message block Protocol

 

Nfs network can be used for linux-based sharing.FileSystem
Samba is required between linux and windows.
Samba uses netbios (network basic input and output system)
Netbeui (netbiosExTenEdUser interface)


Samba is controlled by two daemon
Nmbd is used to manage working groups, netbios name parsing, and other udp port 137,138


Smbd is used to manage the directories shared by samba hosts, file tCp139,445

Features:
1. Support for more detailed Access Control
2. cross-platform (linux and windows) File Sharing

The configuration is as follows:

[Root @ li ~] # Yum list |GrepSamba
This system is not registered with RHN.
RHNSuPport will be disabled.
Samba-common.i386-Public toolkit, including samba. conf and test tool testpa for detecting its syntaxRm
Samba. i386 -- samba Server
Samba-client.i386-client tool commands
Samba-swat.i386-graphical samba Configuration tool for web interfaces
[Root @ li ~] # Yum install samba *-y


Server-side master configuration file:/etc/samba/smb. conf
File/etc/samba/lmhosts corresponding to netbios Name and ip address
Password to store files:/etc/samba/passdb. tdb -- use samPasswd-A is added to the user.

[Global] -- Define global Parameters
Workgroup = MYGROUP -- Define a workgroup
Server sTrIng = Samba Server Version % v -- defines the Server description
Security = user -- defines the working mode: share, user, domain, ads
Passdb backend = tdbsam -- use the local. tdb file to save the account and password
Load printers = yes -- load the printer
Cups options = raw -- printer type
[Homes] -- reserved Resource Name
Comment = Home Directories
Browseable = no
Writable = yes
[Printers] -- reserved Resource Name
Comment = All Printers
Path =/var/spool/samba
Browseable = no
Guest OK = no
Writable = no
Printable = yes


Security =
Share without password, including anonymous users
User uses samba's own password database
Server, domain, ads use the password of the external host

Shared directory Parameters

Whether browseable is visible
Public allows all users who can log on to the console to view
Guest OK is the same as public. You can use either of them.
Writable?
Whether read-only is read-only. This parameter conflicts with writable at the same time, and the Setting Value in the future is the main one.

Lab 1:

Use the linux client tool for testing:
Smbclient-Ftp-Like client to access SMB/CIFS resources
On servers

[Root @ li ~] # Smbclient-L // 10.1.1.45
Password: -- press enter to log on as an anonymous user, but no shared resources are displayed. Only basic information about the server is displayed.

[Root @ li ~] # Smbclient-L // 10.1.1.45-U a -- use the user name to log on, Login Failed
Password:
SessionSetUp failed: NT_STATUS_LOGON_FAILURE


Cause:
1. security = user mode by default. This mode specifies that the password is required for access to the user, except for anonymous users.
2. the samba account has two requirements: 1. The requirement is system user 2.CommandAdd it to the samba Service

Smbpasswd-change a user's SMB password

[Root @ li ~] # Smbpasswd-a -- Add User a to the samba user
