LAB 1: Footprinting a Network

One of the most astounding side-effects of the Internet is how readily accessible information is about individuals, organizations, and computer systems. This assignment is designed to give you some experience in obtaining this information.

Materials Needed:

1. Computer running either Windows or Linux/Unix
2. Internet connection
3. Sam Spade (http://www.samspade.org/ssw/download.html)

NETWORK SYSTEMS

• Use NSLookup to determine the IP address of cpsc.ColumbusState.edu and crta.info (you may substitute your computer on your campus)

______________________________ ______________________

• Determine who administers these computers and any other information readily available. You may use any websites or tools like ARIN, Neotrace, Whois (http://www.networksolutions.com/en_US/whois/ ), or other open source public information. Describe how you found the information. You now have all kinds of information that would allow you to take advantage of vulnerabilities at that site.

• cpsc.ColumbusState.edu,

• crta.info,

• sail-1.ColumbusState.edu,
