How to Learn Samba in LINUX

How to Learn Samba in LINUX-Linux Enterprise Application-Linux server application information. 1. smb. conf description
---------------------------------------------------------------------
# This is the main Samba configuration file. You shoshould read
# Smb. conf (5) manual page in order to understand the options listed
# Here. Samba has a huge number of retriable options (perhaps too
# Success !) Most of which are not shown in this example
#
# Any line which starts with a; (semi-colon) or a # (hash)
# Is a comment and is ignored. In this example we will use #
# For commentry and a; for parts of the config file that you
# May wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# To check that you have not made any basic syntactic errors.
#
#====================================== Global Settings ==================== ======================================
[Global] describes the overall environment
# Workgroup = NT-Domain-Name or Workgroup-Name
Workgroup = workgroup: Set the name of the workgroup. The name will appear in the network neighbors of Windows and the network servers of Linux.
Netbios name = aaa set netbios bios name
# Server string is the equivalent of the NT Description field
Server string = Samba Server server description
# This option is important for security. It allows you to restrict
# Connections to machines which are on your local network.
# Following example restricts access to two C class networks and
# The "loopback" interface. For more examples of the syntax see
# The smb. conf man page
; Hosts allow = 192.168.1. 192.168.2. 127. It strictly limits the IP address range that can access the Samba Server. By default, all IP addresses are allowed.
# If you want to automatically load your printer list rather
# Than setting them up individually then you'll need this
Printcap name =/etc/printcap printer configuration file path
Load printers = yes whether to share the printer
# It shoshould not be necessary to spell out the print system type unless
# Yours is non-standard. Currently supported print systems include:
# Bsd, sysv, plp, lprng, aix, hpux, qnx, cups
Printing = cups printer type
# Uncomment this if you want a guest account, you must add this to/etc/passwd
# Otherwise the user "nobody" is used
# Guest account = pcguest if you want to remove "pcguest" Anonymous Access #, and ensure that this user exists in/etc/passwd.
# This tells Samba to use a separate log file for each machine
# That connects
Log file =/var/log/samba/% m. log creates different log files for each user logging on to samba in this directory.
# Put a capping on the size of the log files (in Kb ).
Max log size = 0 defines the size of the log file
# Security mode. Most people will want user level security. See
# Security_level.txt for details.
Security = share security Level: share, user, server, and domain
# Use password server option only with security = server
# The argument list may include:
# Password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
# Or to auto-locate the domain controller/s
# Password server = *

# Password Level allows matching of _ n _ characters of the password
# All combinations of upper and lower case.
; Password level = 8 password level settings
; Username level = 8
# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents
Encrypt passwords = yes. The user password must be encrypted.
Smb passwd file =/etc/samba/smbpasswd when you set the password Server to Samba server, you need to use this line to specify the password file to be verified. If it is set to window NT Server, this line is not required. The most important here is the path set for the password file.
# The following is needed to keep smbclient from spouting spurous errors
# When Samba is built with support for SSL.
; Ssl CA certFile =/usr/share/ssl/certs/ca-bundle.crt
# The following are needed to allow password changing from Windows
# Update the Linux system password also.
# NOTE: Use these with 'encryption password' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
# The encrypted SMB passwords. They allow the Unix password
# To be kept in sync with the SMB password.

# You can use PAM's password change control flag for Samba. If
# Enabled, then PAM will be used for password changes when requested
# By an SMB client instead of the program listed in passwd program.
# It shoshould be possible to enable this without changing your passwd
# Chat parameter for most setups.
Pam password change = yes when the user asks to change the password, use PAM without the Local password Program/user/bin/passwd
# Unix users can map to different SMB User names

# This parameter will control whether or not Samba shocould obey PAM's
# Account and session management directives. The default behavior is
# To use PAM for clear text authentication only and to ignore any
# Account or session management. Note that Samba always ignores PAM
# For authentication in the case of encrypt passwords = yes

2. Configure the Samba server
■ 2.1 configure a share-level server
Workgroup = linux
Netbois name = aaa
Printcap name =/etc/printcap
Load printers = yes
Printing = lprng
Guest account = pcguest

Log file =/var/log/samba/% m. log
Max log size = 50
Security = share
Socket options = TCP_NODELAY SO_RCVBUF = 8129 SO_SNDBUF = 9129
[Homes]
Comment = Home Directories
Browseable = yes
Writeable = yes
Valid users = % S
Create mode = 0664
Directory mode = 0775
[Printers]
Comment = All Printers
Path =/var/spool/samba
Browseable = no
Printer name = printer
Public = yes
[Ftp]
Comment = ftp share
Path =/var/ftp
Public = yes
■ 2.2 configure a user-level server

Modify on the basis of share:
Security = share
Change to security = user
Add guest accout = pcguest
Encrypt passwords = yes
Smb passwd file =/etc/samba/smbpasswd
When the configuration file/etc/smb. after setting the user level in conf, you need to set the samba password file and create the smbpasswd account and password so that it is the same as the account and password of/etc/passwd. The method is as follows:
(1) create a local account, generate the password file/etc/passwd, and add all users in/etc/samba/smbpasswd to the file/etc/smbpasswd. Note that this process is to first create an account and password locally, and then
The password file is sent to/etc/samba/smbpasswd. The sequence cannot be reversed, that is, the passwords of local accounts are different from those of samba servers.
# Adduser pcguest
# Passwd pcguest
# Cat/etc/passwd | mksmbpasswd. sh>/etc/samba/smbpasswd
(2) Use the smbpasswd command to set up a samba server password for the account you just created. Note: When you use the smbpasswd command to modify the user password, the local system user account of the modified samba account must already exist.
# Smbpasswd pcguest
(3) restart and support samba server
#/Etc/init. d/smb restart
■ 2.3 configure domain-level servers

You only need to modify the configuration at the user level:
Security = user
Workgroup = linux
Is:
Security = domain
Workgroup = wenda worker wenda is the domain name of the master domain controller.
Add:
Netbios = linux
Password server = wendaserver login uses windows 2000 Master Domain Controller wendaserver as the password server
Comment out:
Smb passwd file =/etc/samba/smbpasswd
