While your article is interesting re building better debugging skills, I wonder how many of the tools mentioned require root access or more than just user access.
Is tcpdump or strace available to those who don't have control over the machine? Or is there a variant that would be available ?
You need root for tcpdump. I don't think you need it for strace. In these situations, you want to reproduce the issue in an environment, where you have root access.
