You're trying to insert unescaped data. One of those variables is a string that has a single quote in it somewhere, indicated by "s foremost network protocol analyzer, and is the de facto (and often de jure) st" in the error message. My guess is that first 's' shown is part of a possessive noun, and the reason it's failing is because of the apostrophe (a single quote).

Your script is completely open to SQL injection. Escape them strings!!
