Samba
Samba is an Open Source/Free Software suite that provides seamless file services to SMB/CIFS clients. Samba runs on most Unix and Unix-like systems, such as GNU/Linux, Solaris, and the BSD variants, including Apple's Mac OS X. It is standard on virtually all distributions of Linux and is commonly included as a basic system service on other Unix-based systems as well.
