When analyzing network or security problems we are often pushed to ask details about the original problem which are more or less private.
As a practical example, this question on Ask Different VMWARE has internet, but OSX not can't receive an efficient answer without a complete TCP/IP configuration at the origin of the problem.
The risk of putting on the Stack Exchange web server such a private information depends highly on the people directly (here for example, users with fake or real names) or indirectly involved (here for example, the manager of the hotel network).
What is the best practice to ask for or to publish, more or less private or sensitive information?
