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?

Many people want to integrate their Microsoft or IBM style desktop machines with their Unix or VMS (etc) servers.
Others want to integrate their Microsoft (etc) servers with Unix or VMS (etc) servers. This is a different problem to integrating desktop clients.
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.

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
