Bad Login

Download the badlogin program. It works sort of like the login program that controls access to UNIX systems, except that instead of actually granting or denying access to anything, it just prints messages, and also it is terrible.

When you run badlogin, it will prompt you for a username; use your actual username from your Chemeketa email (e.g. I would use rsurton). Then, it will prompt you for a password. Your task is to figure out what password to enter to get a message saying you have been granted access. As with the previous assignment, just getting the right answer isn't enough; I expect you to explain how you found the answer and include snippets from using gdb to gather evidence. Put together a document that includes your username and shows what password will grant you access, and how you know. When you are done, export your document as PDF and submit it to elearn.

There is another program included in the download, named extrabadlogin. It is not extra bad, so much as it is worth extra because some techniques that will solve badlogin do not work on extrabadlogin. You only need to solve badlogin for "Yes" credit, but solving both puzzles with a good writeup is worth "Wow!" credit.
