Describe the top 3 gotchas of using traceroute to diagnose network problems. :) That's something you're not likely to look up if you're in the middle of a connectivity event.... ------------------------------------------------ It's these types of questions that're hard for some in an interview even though they know their stuff. One might get nervous wondering if (s)he gave the interviewer the three that they're looking for and stumble on the next question even though the next question seems easy to the interviewer. I'd ask the question a little differently: I have a network problem between 2 sites and there is a firewall between them that is blocking ICMP and nothing else. How would you complete a traceroute to troubleshoot? (Use BSD or tcptraceroute, for example) Then, it turns the questioning into operational. scott

Yes, but it's different to knowing stuff by heart that you can just research. Note that I do not mention any specific search tool, I barely even use the largest search engines. The "top 3 gotchas of using traceroute" is something I would expect to be part of basic skills that someone with at least mid level knowledge in the field would possess. But how exactly traceroute does its thing is something I personally like to read about but not remember word for word.
