Abstract

Use the GNU toolchain, including strace and gdb to analyze a simple network application.

Assignment

Using your Ubuntu virtual machine and the GNU toolchain, complete the following. All activities must

be done using the Linux command prompt in the bash shell.

Provide a single document detailing the activity, including your process, methods, and results. All

screenshots should be nicely resized and annotated. Your document should show what you did, how

you did it$,$ display the results, and explain what happened.

Include all of the commands used during your work in separate text file to be included with your

submission.

Introduction

Compile and run the provided application. The application is a network server. Start the server, then use

NetCat to access the server. After runing and understanding the behavior of the program, use Strace and

GDB to gather more information.

Activity

Compile and run the provided source code. When compiling, be sure to include debugging symbols.

Use netstat, strace, gdb$,$ and other tools to analyze the running process. Document the actions and

activites of this program. Clearly document what it does and how this can be determined.

In addtion to netstat, strace, gdb$,$ and nc$,$ find $2$ other GNU tools to analyze the behavior of the

provided program. These should be simple command line utilities covered in text or lecture.

Conclusion

In addition to your own conclusion, include the following:

Discuss how we can confirm the actions and activites of unknown or untrusted executables. What

additional methods could be employed?
