AccessNFS Gateway for Windows Server:
The First NFS Gateway
for Windows Integration

AccessNFS Gateway was the first NFS® gateway for Windows NT®/2000 Servers in the Industry. Time-tested, industry-proven and enterprise-ready.

With Gateway, a Windows NT/2000 Server attaches to NFS file and print resources using the industry-standard NFS protocol, then reshares these devices as standard Windows networking SMB connections. Administrators gain centralized network control. Users gain easy, secure, and transparent access to NFS resources without learning new commands. Files remain on the NFS host system, so Windows and UNIX users gain access to files without duplicating data. Individual Windows user identities are mapped to NFS accounts as they are passed through the Gateway, ensuring security and maintaining file access privileges.

AccessNFS Gateway was built using the same technology found in DiskAccess™ for Windows - SSC's premier NFS client product. AccessNFS engineers and Microsoft jointly developed the underlying mini-redirector technology used in DiskAccess. This technology redefines how installable file systems such as NFS work with the Windows operating system, simplifying system administration, improving speed, and providing seamless integration. With the ease and transparency of Gateway, SSC sets a new standard for integrating mixed networking environments.

Save by buying only what you need. If you have a 200-user site, you may need to provide NFS access for all of your users - but only for a handful of clients at any one time. Using AccessNFS Gateway, you can provide access for a specific number of users at a given time. Because AccessNFS Gateway allows a large base of Windows users to access UNIX and other NFS-based file servers through a single Windows Server, you can purchase only as many seats as you need or add to your Gateway user base as needed. This server-based product is offered in numerous configurations of client seats - a flexible and cost-effective solution to your NFS client needs. And the configurations are licensed concurrently, meaning that they're available for any combination of users as the need is determined.

SSC has redefined the way Network File System (NFS) operates in a Windows environment, setting the standard for Windows and UNIX interoperability.  SSC understands the need to share data between Windows and UNIX systems. AccessNFS Gateway and our other AccessNFS Solutions were developed to meet the demanding needs of the corporate user.

Installation is simple AccessNFS Gateway takes advantage of Microsoft's native TCP/IP protocol stack and utilities, ensuring quick installation, broad support for network adapters, and the fewest compatibility problems with third-party applications. Once Gateway is installed, the administrator authenticates and maps the NFS directory and print resources of one or more systems to equivalent Windows shares. Then when Windows clients browse the Windows Server, these shares appear as native Windows Server resources. And AccessNFS Gateway can be accessed by a wide variety of Windows clients - including MS-DOS®, Windows 3.1, Windows for Workgroups, Windows 95, Windows NT, 2000, XP and Windows 2003 systems. AccessNFS Gateway is compatible with all standard NFS server implementations and requires no additional software on the NFS host system. Account control is centralized and flexible The Windows administrator controls access to Windows shares. Windows user security identities (SIDs) are mapped to NFS user identities (UIDs) on a one-to-one or many-to-one basis - allowing individual Windows users to appear as unique users or many Windows users to appear as a single NFS user account. In addition, an automapping feature links Windows accounts to NFS accounts by automatically associating like names between systems. Unauthorized users can be blocked or passed through with anonymous access privileges. NFS administrators can limit directory access to the Windows Server and control file access privileges through user (UID) and group (GID) identification.

Administration is easy
When it's time to upgrade AccessNFS Gateway or add additional seats, you need only update the server - completely eliminating the hassle of updating NFS client software on every node. Because NFS clients do not need to be deployed on every system, client systems do not have to run dual-protocol stacks or deal with memory or disk limitations.

NFS access is secure
AccessNFS Gateway eliminates clear-text NFS PC client password schemes, relying instead on the secure, encrypted C2 security native to the Windows network environment. The Windows NT/2000 Server provides a secure pass-through to the NFS-based server. The client can browse and mount as needed. Gateway is a boon for campus and dial-in sites - users have remote, secure access to NFS resources, maintaining separate identities as they pass through the Gateway. Access to Windows mounts is controlled by the Windows administrator, and NFS connection and file access privileges are controlled by the NFS server administrator.

AccessNFS Gateway is built on DiskAccess technology
Like SSC's premier NFS client software, DiskAccess for Windows, AccessNFS Gateway fully incorporates NFS into the Windows environment. You can streamline your operations by accessing resources more easily, reducing NFS server load, improving overall network performance, and minimizing NFS implementation and support costs. Working transparently with Network Neighborhood and Explorer, the Gateway easily mounts and accesses multilevel (deep) mount points. AccessNFS Gateway maximizes throughput with full support for NFS version 3 and 64K read-and-write packets. In addition, Gateway's multithreaded design ensures top performance under the multitasking 32-bit Windows NT/2000 operating system. Performance can be improved by dividing users among several Gateway servers or using higher speed processors, multi-processor systems, switched networks, or higher speed networks.

AccessNFS Gateway - the right NFS solution for you
Now you can tailor your NFS connectivity to meet your company's unique requirements. If your users need occasional access to NFS resources, AccessNFS Gateway is your NFS solution. Or if some of your users need frequent connection to NFS resources, install DiskAccess on their workstations. AccessNFS Gateway is an innovation in NFS connectivity because - for the first time - you determine the perfect fit.
