Overview

Samba on LINUX for zSeries
Allows you to consolidate your entire file/print system onto a single machine. This can help you significantly reduce costs and simplify administration while achieving enhanced scalability, availability and reliability.

Enabling UNIX and Microsoft Windows to coexist
Samba is a suite of programs that work together to allow clients to access a server's file space and printers via the Server Message Block (SMB) and Common Internet Filesystem (CIFS) protocols which can be run on almost every variant of UNIX.

Open Source

Samba is an open source software available free-of-charge according to the rules of the GNU Public License. It enables UNIX and Windows to coexist successfully on the same network, on the level of file and print sharing. It allows UNIX systems to move into a Windows 'Network Neighborhood'. With Samba, UNIX servers act like any other Windows server, offering their resources to SMB/CIFS clients so UNIX servers appear just like a PC server.

Functions

Operates with a Linux server to function as a file/print server for Windows networks
Acts as a NetBIOS name server (NBNS), otherwise known as Windows Internet Name Service (WINS)
Participates in NetBIOS browsing and master browsing elections 1
Provides a gateway for the synchroni- zation of UNIX and Windows NT� passwords
Enables users with Samba client software to access any shared directory or printer on Windows NT servers or Samba servers and allows UNIX machines to access Windows NT files
Enables users, through the Samba File System (SMBFS), to mount a shared resource from a Windows NT server or a Samba server in their directory structure. (Only available on Linux.)

1 Available later this year.

Function Overview

Windows 95/98, Windows NT, Windows 2000 and OS/2 Warp clients do not require extra software to access a Samba server. These operating systems all support NetBIOS over TCP/IP (NBT) which is all that is required to access a Samba server.

Features

Provides a Windows-like SMB file and print server
Participates in an existing domain (pass-through authentication)
Supports browsing, either as the domain or local master browser
Provides a NetBIOS name resolution service (similar to Microsoft WINS)
Offers a web-based configuration tool (SWAT)
Supports a command line SMB client (similar to FTP)
Offers a tar extension for backing up client PCs.

Samba's two key programs

smbd and nmbd translate file attributes, file names, user authentication and network architecture between UNIX, Linux and Windows systems.

Share level security

In share level security, the client only needs to provide a password to access a share. A username is not required and any files contained in the share can be accessed.

User level security

In user level security, the client must provide a username and password to access a share. Additionally, user level security can protect individual files within a share.

Windows servers

Samba implements most of the functions implemented by Windows servers, thus allowing resources to be easily shared with Windows clients of all types.

IBM @server zSeries 900

Designed to avoid or recover from failures - high availability is realized through very high component reliability and design features that assist in providing fault avoidance and tolerance as well as permitting concurrent maintenance and repair.
Scalability - zSeries servers are configurable in numerous ways, offering unparalleled flexibility to speed deployment. In addition, hundreds of Linux images can be hosted using z/VM or the S/390 Virtual Image Facility for Linux.
Application flexibility - Linux for zSeries supports the new 64-bit z/Architecture and extends choice of application flexibility.
On-demand flexibility - The z900 can automatically direct resources to priority work through Intelligent Resource Director. This combined with z/OS provides the ability to intelligently manage numerous operating system images with dynamic workload management and physical resource balancing across logical partitions.
