  1. Samba http://en.wikipedia.org/wiki/Samba_%28software%29

  2. Samba • A free software re-implementation of SMB/CIFS networking protocol • Released under the GNU General Public License • The term Samba comes from inserting one vowel, twice, into the name of the standard protocol used by the Microsoft Windows network file system, "SMB" (Server Message Block).

  3. Samba • As of version 3 • Samba provides file and print services to various Microsoft Windows clients • Can integrate with a Windows Server domain • Either as a Primary Domain Controller (PDC) • Or as a Domain Member • Can be part of an Active Directory domain • Samba runs on most Unix and Unix-like systems • E.g. Linux, Solaris, and the BSD variants, including Apple's Mac OS X Server (which was added to the Mac OS X client in version 10.2). • Samba is standard on nearly all distributions of Linux • Commonly included as a basic system service on other Unix-based operating systems as well

  4. History

  5. History • Andrew Tridgell developed the first version of Samba Unix in 1992, at the Australian National University • Used a packet sniffer to do network analysis of the protocol used by DEC PATHWORKS server software • "nbserver 1.5" was released in December 1993 • Later discovered that the protocol was largely identical to that used by other network server systems • Including Microsoft's LAN Manager software • Decided to focus on Microsoft network compatibility after that

  6. History • Originally called smbserver • Name changed because of a trademark notice from the company "Syntax“ • Sold a product named TotalNet Advanced Server, and also owned the trademark for "SMBserver" • Name "Samba" was arrived at by running the Unix command grep through the system dictionary looking for words that contained the letters S, M, and B in that order • i.e. grep -i 's.*m.*b.*' /usr/share/dict/words

  7. Features

  8. Features • Samba is an implementation of: • Dozens of services and a dozen protocols, including • NetBIOS over TCP/IP (NBT) • SMB • CIFS (an enhanced version of SMB) • DCE/RPC • More specifically, MSRPC • The Network Neighborhood suite of protocols • A WINS server also known as a NetBIOS Name Server (NBNS) • The NT Domain suite of protocols which includes NT Domain Logons • Secure Accounts Manager (SAM) database • Local Security Authority (LSA) service • NT-style printing service (SPOOLSS) • NTLM • Active Directory Logon • involves a modified version of Kerberos • A modified version of LDAP • These services and protocols are incorrectly referred to as NetBIOS and/or SMB • Samba can also see and share printers

  9. Features • Samba sets up network shares for chosen Unix directories (including all contained subdirectories) • Appear to Microsoft Windows users as normal Windows folders accessible via the network • Unix users can either mount the shares • Directly as part of their file structure • Use a utility, smbclient (libsmb) installed with Samba to read the shares with a similar interface to a standard command line FTP program • Each directory can have different access privileges overlayed on top of the normal Unix file protections • For example: home directories would have read/write access for all known users, allowing each to access their own files • Would still not have access to the files of others unless that permission would normally exist • Note that the netlogon share is the logon directory for user logon scripts • Typically distributed as a read only share from /etc/samba/netlogon

  10. Features • Configuration is achieved by editing a single file • Usually installed as /etc/smb.conf or /etc/samba/smb.conf • Using poledit Samba can also provide: • User logon scripts • Group policy implementation
