Unreferenced stub auto yes date December 2009 PC Network was a Local area network LAN system consisting of network card s, cable s, and a small device driver known as NetBIOS Network Basic Input Output System . It used a data rate of 2 Mbit s . The original PC Network hardware was available in two varieties, baseband and broadband. The baseband version connected computers in daisy chain style using twisted pair cables with RJ45 connectors. Interface cards had two RJ45 sockets for connecting to left and right neighbor nodes. The unused sockets at the ends of the network segment had to be fitted with Electrical termination terminator s. The more expensive and less widely used broadband version communicated over 75 Co axial cable Standard cable types RG 11 type cable on separate transmit and receive frequency ranges, using a head end device to translate between the two signals.

NWLink packages data to be compatible with client server services on NetWare Networks. However, NWLink does not provide access to NetWare File and Print Services. To access the File and Print Services the Client Service for NetWare needs to be installed. Using NWLink IPX SPX NetBIOS NWLink IPX SPX NetBIOS Compatible Transport is Microsoft s implementation of the Novell IPX SPX Internetwork Packet Exchange Sequenced Packet Exchange protocol stack. The Windows XP implementation of the IPX SPX protocol stack adds NetBIOS support. The main function of NWLink is to act as a transport protocol to route packets through internetworks. By itself, the NWLink protocol does not allow you to access the data across the network. If you want to access NetWare File and Print Services, you must install NWLink and Client Services for NetWare software that works at the upper layers of the OSI model to allow access to File and Print services . One advantage of using NWLink is that is easy to install and configure. Configuring NWLink IPX SPX The only options that are configured for NWLink are the internal network number and the frame type . Normally, you leave both settings at their default values. The internal network number is commonly used to identify NetWare file servers. It is also used when you are running File and Print Services for NetWare or using IPX routing. The frame type specifies how the data is packaged for transmission over the network. If the computers that are using NWLink use different frame types, they are not able to communicate with each other. The default setting for frame type is Auto Det ... more details

Unreferenced stub auto yes date December 2009 Pathworks was the tradename used by Digital Equipment Corporation of Maynard, Massachusetts Maynard , Massachusetts for a series of programs that eased the interoperation of Digital s minicomputer s with personal computer s. The server part of Pathworks ran on VAX VMS or Ultrix and enabled a DEC VAX or VAXcluster to act as a file and print server for client IBM PC compatible and Apple Macintosh Macintosh workstations. Pathworks server was derived from LanMan X , the portable version of OS 2 LAN Manager . Once installed onto the PCs, the Pathworks client provided the following features DECnet end node connectivity with the host systems PowerTerm 525 Terminal emulation software from Ericom File transfer software For clients running a GUI such as Windows 3.x, additional components available included an X window system server, allowing clients to access graphical apps running on VMS or UNIX hosts, and clients for DEC s ALL IN 1 email and groupware system. Although primitive by modern standards, Pathworks was very sophisticated for its time far more than just a file and print server, it made client microcomputers into terminals and workstations on a DEC network. LanMan normally ran across Microsoft s basic, non routable NetBIOS NetBIOS NetBEUI NetBIOS Frames protocol NBF protocol, but Pathworks included a DECnet stack, including layers like the LAT transport used for terminal sessions. The complexity of DECnet by 1980s PC standards meant that the Pathworks client was a huge software stack to have resident in MS DOS configuring the Pathworks client was a complex task, made more so by the need to preserve enough Conventional memory for DOS applications to run. To keep a reasonable amount of base memory free mandated the use of QEMM or a similar memory manager . Pathworks was available for both Windows and Mac computer systems.

A naming scheme is a plan for naming objects. In computing , naming schemes are often used for objects connected into computer network s. Naming schemes in computing Large networks often use a systematic naming scheme, such as using a location e.g. a department plus a purpose to generate a name for a computer. For example, a web server for a marketing department may be called marwww01 . However, smaller networks will frequently use a more personalized naming scheme to keep track of the many hosts. Popular naming schemes include trees, planets, rocks, etc. Network naming can be hierarchical in nature, such as the Internet s Domain Name System . Indeed, the Internet employs several universally applicable naming methods Uniform Resource Names Uniform Resource Name URN , Uniform Resource Locators Uniform Resource Locator URL , and Uniform Resource Identifiers Uniform Resource Identifier URI . For the technically inclined, the following article is worth perusing http www.w3.org TR uri clarification .

The Transport Driver Interface or TDI is the protocol understood by the upper edge of the Transport layer of the Microsoft Windows Kernel computer science kernel network stack. Transport Providers are implementations of network protocols such as TCP IP , NetBIOS , and AppleTalk . When user mode binaries are created by compiling and linking, an entity called a TDI client is linked into the binary. TDI clients are provided with the compiler . The user mode binary uses the user mode API of whatever network protocol is being used, which in turn causes the TDI client to emit TDI commands into the Transport Provider. Typical TDI commands are TDI SEND, TDI CONNECT, TDI RECEIVE. The purpose of the Transport Driver Interface is to provide an abstraction layer, permitting simplification of the TDI clients.

Orphan date August 2009 A Hack Trapper is an Application software application run on a sometimes deliberately unprotected machine or network with the intention of alerting the user of connection attempts. A Hack Trapper listens on certain TCP and UDP port ports which are commonly used to gain unauthorized access to a machine or data on it. When a connection is made, the user is alerted in some way. In most cases the source IP address is logged to help trace the connection. Some of these ports include Remote Desktop Protocol , Windows File Sharing, NetBIOS , as well as many Trojan horse computing Trojan Horses and Backdoor computing Backdoors . Security It has been controversial over whether Hack Trappers actually make a machine more secure or not. The idea is that the user can report the incident to the Internet service provider ISP of the connecting machine, or even law enforcement. This way the connecting machine will be less likely to try to access or interfere with the system in the future. On the other hand, some people believe them to make a computer less secure, since they will make a system much more visible to the internet.

Unreferenced stub auto yes date December 2009 LAN Manager was a Network operating system Network Operating System NOS available from multiple vendors and developed by Microsoft in cooperation with 3Com Corporation . It was designed to succeed 3Com s 3 Share network server software which ran atop a heavily modified version of MS DOS . Development History LAN Manager was based on the OS 2 operating system co developed by IBM and Microsoft. It originally used the Server Message Block protocol atop either the NetBIOS Frames protocol NBF or a specialized version of the Xerox Network Systems XNS protocol. These legacy protocols had been inherited from previous products such as MS NET for MS DOS , Xenix NET for Xenix MS Xenix , and the afore mentioned 3 Share. A version of LAN Manager for Unix based systems called LAN Manager X was also available. In 1990, Microsoft announced LAN Manager 2.0 with a host of improvements, including support for TCP IP as a transport protocol. The latest version LAN Manager, 2.2, which included an MS OS 2 1.31 base operating system, remained Microsoft s strategic server system until the release of Windows NT 3.1 Windows NT Advanced Server in 1993. Many vendors shipped licensed versions, including 3Com Corporation 3 Open HP LAN Manager X IBM LAN Server Tapestry Torus Security Vulnerability LAN Manager authentication uses a particularly weak method of Cryptographic hash function hashing a user s password known as the LM hash algorithm.
