(Fedora: Lesson 11)

{ Basic Samba Configuration }

• What is Samba? 
  • The name Samba comes from SMB (Server Message Block), the name of the standard protocol used by the Microsoft Windows network file system. SMB is a protocol for sharing files, printers, serial ports, and communications abstractions such as named pipes and mail slots between computers.

   

  • Samba provides file and print services for various Microsoft Windows clients and can integrate with a Windows Server domain, either as a Primary Domain Controller (PDC) or as a domain member.

   

  • It can also be part of an Active Directory domain.  

   

  • Samba runs on most Unix and Unix-like systems, such as GNU/Linux, Solaris, AIX and the BSD variants, including Apple's Mac OS X Server (which was added to the Mac OS X client in version 10.2).
