OpenSSH for Windows

OpenSSH for Windows is a free package that installs a minimal OpenSSH server and client utilities in the Cygwin package without needing the full Cygwin installation. This is similar to the package formerly available from NetworkSimplicity.

The OpenSSH for Windows package provides full SSH/SCP/SFTP support. SSH terminal support provides a familiar Windows Command prompt, while retaining Unix/Cygwin-style paths for SCP and SFTP.

WiMAX

WiMAXWiMAX is defined as Worldwide Interoperability for Microwave Access by the WiMAX Forum, formed in June 2001 to promote conformance and interoperability of the IEEE 802.16 standard, officially known as WirelessMAN. The Forum describes WiMAX as “a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL”.

“WiMAX is not a technology, but rather a certification mark, or ‘stamp of approval’ given to equipment that meets certain conformity and interoperability tests for the IEEE 802.16 family of standards. A similar confusion surrounds the term Wi-Fi (Wireless Fidelity), which like WiMAX, is a certification mark for equipment based on a different set of IEEE standards from the 802.11 working group for wireless local area networks (WLAN). Neither WiMAX, nor Wi-Fi is a technology but their names have been adopted in popular usage to denote the technologies behind them. This is likely due to the difficulty of using terms like ‘IEEE 802.16’ in common speech and writing.”

Create a report of all the users and groups in my domain

There are many tools and utilities designed to do so, but none are native W2K GUI. There are no graphical or command line utilities that produce comprehensive reports on groups, users and permissions included with the Windows Operating System or the Resource Kit. The NET commands and the Windows Resource Kit ADDUSERS.EXE and PERMS.EXE utilities can be used to create limited administrative reports by piping the output to a text file.

Erro de protecção do NDIS

Ao instalar o Microsoft Windows95 ou Windows98 num sistema com uma CPU superior a 2,1 GHz, a instalação falha e mostra a mensagem de erro: “While initializing device NDIS: Windows protection error.” (Erro de proteção do Windows na inicialização de dispositivo NDIS).

Este erro é causado pelo código de calibração de temporização no driver NDIS que ocorre quando a CPU funciona com 2,20 GHz ou mais rápida. O problema não ocorre em CPUs de 2,10 GHz ou mais lentas.

Esta questão de temporização não afecta o Windows98 Segunda Edição.

Para informações adicionais sobre este problema, consulte o artigo de suporte Q312108 da microsoft.
