The Samba software suite is a collection of programs that implements the SMB protocol for UNIX systems. This protocol is also known as the Common Internet File System (CIFS). The NetBIOS protocol is implemented by the nmbd daemon.
The SMB server daemon smbd provides file sharing and printing services to Windows clients. The server provides file space and printer services to clients via the SMB/CIFS protocol. The nmbd daemon is a NetBIOS name server that provides NetBIOS naming services to clients . It understands and can reply to NetBIOS over IP name service requests, like those produced by SMB/CIFS clients (windows).
