Warning: Can’t Load Net::Whois::IP Module, Whois Queries Desabled

In going through all the tools with Alex on Backtrack I have discovered a few bugs and missing modules or libs. I will be writting posts on how to fix them but I will also be adding the fix’s to Backtrack svn as well. This morning I was writting the article on Dnsenum by my buddy Barbsie and I ran into a missing perl module.

Use JavaScript To Require Data To Be Entered Into A Form Field Before It Can Be Submitted

I needed a simple way to require data in a form field before it could be submitted. There are chunks of JavaScript code all of the Internet that allow you to do this easily so I selected one and added it to my form with ease. One small issue I had was it required that the name attribute be modified for it to work which caused an issue with the application I was adding it to. The issue was the name attribute was modified thus it would not save the data to the proper database table column. Below I explain how to add this bit of JavaScript to your form and modify your form for it to function properly.
