 It is essentially a collection of tools contained within an organized code structure that is interface-able. These tools are wrapped up in such a way, that the user does not need to know or fully understand the inter-workings of their undertakings; only how to implement them. He/she can install the software and follow on-screen instructions to accomplish ordinarily complex and/or extensive tasks such as starting a web server, monitoring network traffic, or assigning rights and privileges to users for network resources. These tools will not be solely exclusive to the project and will hopefully find their way into others projects as they will find "code leverage" just as useful.

 Not all Ethernet cable is created equally. What’s the difference, and how do you know which you should use? Let’s look at the technical and physical differences in Ethernet cable categories to help us decide.
 

 Contains an excellent table on trouble shooting
It has some detailed explanations on the basics of TCP/IP and how to actually handle it.
 

 MikroTik has been developing, installing and selling wireless routers since 1995. MikroTik's newest software product, MikroTik RouterOS v3, is a software router system which makes it easy for any VAR, ISP, or network admin to make a PC router for wireless, wide area, or local area networks.

When troubleshooting, you will almost always at least once need information from links posted here.
 

 Aircrack is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, thus making the attack much faster compared to other WEP cracking tools. In fact, aircrack is a set of tools for auditing wireless networks.
 

 All of your MX record, DNS, blacklist and SMTP diagnostics in one integrated tool. Input a domain name or IP Address or Host Name. Links in the results will guide you to other relevent tools and information. And you'll have a chronological history of your results.
