Samba is the standard Windows interoperability suite of programs for Linux and Unix.
Samba is Free Software licensed under the GNU General Public License, the Samba project is a member of the Software Freedom Conservancy.
Since 1992, Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol, such as all versions of DOS and Windows, OS/2, Linux and many others.
Samba is an important component to seamlessly integrate Linux/Unix Servers and Desktops into Active Directory environments. It can function both as a domain controller or as a regular domain member.
Since ArcaOS 5, a Netdrive plugin based on Samba 4.x, which supports SMB2+ has been included.
