Netcat for NT is the tcp/ip "Swiss Army knife" that never made it into any
of the resource kits. It has proved to be an extremely versatile tool on
the unix platform. So why should NT always be unix s poor cousin when it
comes to tcp/ip testing and exploration? I bet many NT admins out there
keep a unix box around to use tools such as Netcat or to test their systems
with the unix version of an NT vulnerability exploit. With Netcat for NT
part of that feeling disempowerment is over.
LwIP是瑞士計算機科學院(Swedish Institute of Computer Science)的AdamDunkels等開發的一套用于嵌入式系統的開放源代碼TCP/IP協議棧。LwIP的含義是Light Weight(輕型)IP協議。LwIP可以移植到操作系統上，也可以在無操作系統的情況下獨立運行。LwIP協議的基礎是在減少對硬件資源占用的前提下完成TCP/IP協議的主要功能
