Very good beginner introduction to wireshark. Could have been slightly more in depth with examples on how to detect and solve some network problems.
I normally don't want to speak badly of such services, and I hope I'm alone in this, but the Linux VM used for this course was missing Firefox and didn't have internet access, so several of the taks couldn't be completed. I passed the course quiz using my own common sense and knowledge dervied from the course at the time, but still feel as though the VM should have been up to date. Has anyone else had this experience? Overall, I felt this course was a decent introduction to Wireshark so I don't regret the undertaking. However, I think other prospective students should be aware of the aforementioned pitfalls.
