samba-2.0.3-19990228 (SMB)

WHAT IS SMB?

This is a big question.

The very short answer is that it is the protocol by which a lot of PC-related machines share files and printers and other informatiuon such as lists of available files and printers. Operating systems that support this natively include Windows NT, OS/2, and Linux and add on packages that achieve the same thing are available for DOS, Windows, VMS, Unix of all kinds, MVS, and more. Apple Macs and some Web Browsers can speak this protocol as well. Alternatives to SMB include Netware, NFS, Appletalk, Banyan Vines, Decnet etc; many of these have advantages but none are both public specifications and widely implemented in desktop machines by default.

The Common Internet Filesystem (CIFS) is what the new SMB initiative is called. For details watch http://samba.org/cifs. 

WHY DO PEOPLE WANT TO USE SMB?

1. Many people want to integrate their Microsoft or IBM style desktop machines with their Unix or VMS (etc) servers.
2. Others want to integrate their Microsoft (etc) servers with Unix or VMS (etc) servers. This is a different problem to integrating desktop clients.
3. Others want to replace protocols like NFS, DecNet and Novell NCP, especially when used with PCs.

WHAT CAN SAMBA DO?

Here is a very short list of what samba includes, and what it does. For many networks this can be simply summarised by "Samba provides a complete replacement for Windows NT, Warp, NFS or Netware servers."

• a SMB server, to provide Windows NT and LAN Manager-style file and print services to SMB clients such as Windows 95, Warp Server, smbfs and others.
• a NetBIOS (rfc1001/1002) nameserver, which amongst other things gives browsing support. Samba can be the master browser on your LAN if you wish.
• a ftp-like SMB client so you can access PC resources (disks and printers) from unix, Netware and other operating systems
• a tar extension to the client for backing up PCs
• limited command-line tool that supports some of the NT administrative functionality, which can be used on Samba, NT workstation and NT server.

  For a much better overview have a look at the web site at http://samba.org/samba, and browse the user survey.

  Configure

• It's a simple example /etc/smb.conf

  [global] workgroup = hoge server string = Samba Server coding system = EUC password level = 8 guest accout = guest status = yes dead time = 360 log file = /var/log/samba/log.%m log Level = 1 [homes] comment = Home Directories read only = no browseable = no create mode = 0655 [Public] comment = Public Directory path = /home/samba/ public = yes writable = yes create mode = 0655 write list = @users #[CD-ROM] #comment = WinServer CD-ROM Drive #path = /mnt/cdrom #public = yes #writable = no #printable = no

  How to start

  # /etc/rc.d/init.d/smb restart

  How to test

  # testparm | less

  Printer

• Check lpd process

  # ps ax | grep lpd   288  ?  S    0:00 lpd

• /etc/smb.conf

  [global] ... load printers = yes ... [printers]    comment = All Printers    path = /var/spool/samba    browseable = no # Set public = yes to allow user 'guest account' to print    guest ok = no    writable = yes    printable = yes

• /etc/printcap

  canon BJC-80v:\         :sd=/var/spool/lpd/lp:\         :mx#0:\         :sh:\         :lp=/dev/lp1:

  Samba Web Administration Tool

• Edit /etc/services

  swat            901/tcp                         # Add swat service used via ined

• Edit /etc/inetd.conf

  swat    stream  tcp     nowait.400      root    /usr/sbin/swat swat

• Restart

  /etc/rc.d/init.d/inetd restart

  WINS (Windows Internet Name Service)

• To be WINS Server

  [global] wins support   = yes domain master   = yes local master    = yes preferred master= yes os level        = 65

• To be WINS Client

  [global] wins support   = no wins server     = 192.168.2.1

  Primary Domain Controler

• To be a Primary Domain Controler /etc/smb.conf

  [global] workgroup       = hoge domain logons   = yes security        = user encrypt passwords = yes logon path      = \\%N\%U\Profiles smb passwd file = /etc/samba/smbpasswd [homes] writable        = yes browseable      = no hide dot files  = yes [Profiles] writable        = yes browseable      = no [netlogon] comment         = Network Login Service path            = /home/samba/netlogon writable        = no share modes     = no browseable      = no [cdrom] comment         = CD ROM path            = /mnt/cdrom read only       = yes public          = yes writable        = yes browseable      = no hide dot files  = yes

• To be a file server /etc/smb.conf

  [global] workgroup       = hoge security        = share [share] path            = /home/samba/ read only       = yes public          = yes

  Mount a SMB filesystem

  mount -t smbfs -o Options Source Destination
  

  Options

  Option	Description	Example
  username	specifies the username to connect as. If this is not given then the environment variable USER is used.	username=hogeuser
  password	specifies the SMB password. If not given then smbmount will prompt for a passeword, unless the guest option is given.	password=hogesecret
  ro	mount read-only	ro
  rw	mount read-write	rw

  mount -t smbfs -o username=hogeuser,password=hogesecret,ro //hoge-server/mp3 /home/mp3
