AIX Fast Connect Overview

Because AIX Fast Connect uses industry-standard Microsoft networking protocols, PC clients can access AIX files and printers using their native networking client software. PC users can use remote AIX file systems directly from their machines like local file systems, and access AIX print queues like local printers. AIX Fast Connect provides these services by implementing the SMB networking protocol on top of NetBIOS over TCP/IP (RFC-1001/1002). See Windows Networking Concepts for more information about these concepts.


Important features of AIX Fast Connect include:

AIX-application standard and advanced features, including:

Advanced SMB/NetBIOS features, including:


This section includes hardware and software requirements, both for the AIX server and for its PC clients.

Server Hardware Requirements

AIX Fast Connect runs on any machine that supports the AIX 4.3.3 (or later) of the operating system, except for diskless or dataless machines. This server machine must have:

Server Software Requirements

The following are the server software requirements for AIX Fast Connect:

Client Hardware Requirements

Each client PC must have an installed LAN adapter and should be physically connected to a network.

Client Software Requirements

To use Fast Connect, all client PCs must have one of the following operating systems:

To use the Web-based System Manager, a web browser with forms support (for example, Netscape) is required.

Known Conflicts with other Server Software

Like other NetBIOS servers, AIX Fast Connect cannot share ownership of the TCP/IP ports used for NetBIOS (on a single machine). The following NetBIOS-based server-software is known to conflict with AIX Fast Connect. These products should be uninstalled before installing AIX Fast Connect:

        Fileset Description
  SAMBA.* Samba server
  netbios.* NetBIOS/ix for AIX
  connect.* AIX Connections
  TAS.* TotalNet Advanced Server for AIX
  ASU.* Advanced Server for UNIX

Migrating from AIX Connections

Before uninstalling AIX Connections (and NetBIOS/ix) and before installing AIX Fast Connect, read Migrating to AIX Fast Connect from AIX Connections to preserve configuration-data from AIX Connections and NetBIOS/ix.

Also, note that AIX Fast Connect supports only NB-realm networking using NetBIOS over TCP/IP (RFC 1001/1002). AIX Fast Connect does not support IPX/SPX, NetBEUI, orNetware protocols.

Packaging and Installation

This section describes the AIX Fast Connect packaging images and installation requirements.


AIX Fast Connect packaging includes the following images:

Image Description
cifs.base Server Utilities
cifs.client Client Utilities
cifs.msg.* Server Messages (by language)
cifs.websm Web-based System Manager Utilities (AIX 5.1 or later)
cifs.advanced-demo Demo Version (for Windows and OS/2 clients)
-or- cifs.advanced Advanced Server (for Windows and OS/2 clients)
-or- cifs.basic Server (for Windows clients only)

Note: The install files, cifs.basic and cifs.advanced, are mutually exclusive. Standard distributions of AIX Fast Connect contain only one of these images.

These images contain the following filesets:

Image Fileset Fileset Description
cifs.base cifs.base.websm Web-based System Manager support (AIX 4.3.3only)

cifs.base.smit SMIT support

cifs.base.cmd Commands

Installation notes:

Configuration of Network Interfaces

Whenever the AIX Fast Connect server is started, it automatically supports RFC1001/1002 (NetBIOS over TCP/IP) on all AIX TCP/IP interfaces that are currently defined and operational ("up"). No special or additional configuration is required to support these interfaces.

Initial Configuration

During installation, AIX Fast Connect preconfigures itself as an SMB/NetBIOS file server with the following default parameters:

Parameter Initial Value
servername hostname (TCP/IP hostname)
comment "Fast Connect server on hostname"
domainname WORKGROUP
encrypt_passwords 0    (PlainText passwords)
guestlogonsupport 0    (disabled)
networklogon 0    (disabled)
share_level_security 0    (disabled)

In addition, the HOME file share is predefined, and it maps to $HOME, the AIX Fast Connect user's home directory on AIX.

Other server parameters are initially at the default values.


The following limitations apply to AIX Fast Connect:
