For my education, I browse old question and see their answers.
I found this one dealing with how to detect wifi access point on a large network and with no accepted answer. This reminded of my reading of a very interesting chapter in Fyodor's Nmap book dealing exactly with this issue and describing an advanced used of nmap to this goal relying on several criterions to reduce the false positives.
I found that both the reference to this book and a summary description of this technique would be helpful,.
However by mistake I added this answer to a wrong question linked to this one but I deleted this wrong answer immediately to post it under the right question.
But my new answer was also deleted by the moderation team accusing me of spamming.
I honestly thought that deleting my wrong post was the way to do and did not intend any spamming. How should I proceed next time I put my answer under the wrong tab (during my researches I may have many SE tabs in my browser)?
And as a side note I'm not sure to understand why the moderators are so sure that my answer is so useless that it needs to be trashed away, but if you think so you are the boss here :( ...
