If you are an IT student and you are ‘stuck’ on an issue, say so.
Please do not try to pretend that your textbook scenario, or even worse, your cut-and-pasted homework problem is a real-world issue or problem. You will get, at best a grudging and limited response, but more likely you will get a snarky lecture on the benefits of doing your own homework.
I was a student once (ages ago), and know it’s not all fun.
A couple of requests though:
1) Use Google. Do not ask really basic questions like what Ping is, or what DNS is. Show us that we’re helping you, not doing your work for you.
2) Think. Try to solve most of the problem, and ask about the finer points. There are many ideas that work great on paper, yet fail miserably in the real world.
Cheers
