LinuxCBT Samba

LinuxCBT Samba
Samba is the de-facto UNIX/Linux-based software for seamlessly integrating UNIX/Linux environments with MS Windows networks via Samba’s implementation of the SMB protocol suite. Samba allows your UNIX/Linux system to emulate a Windows workstation/server in the network neighborhood/my network places browse list. Consequently, your UNIX/Linux-based system appears to be a Windows-based system featuring file & print shares. Additionally, Samba adds many features not included with stock MS Windows systems.

Let LinuxCBT Samba Edition help to solidify your understanding of Samba and ancillary components.
Recommended Prerequisites:
* Familiarity with MS Windows networking (File & Print shares)
* Access to a GNU/Linux-based PC to install Samba and ancillary components used
* Access to a MS Windows-based system connected to the same network
