That's a completely unfounded assertion. First of all, I don't need
anyone's permission to to a scan. Period. It's a common but nonetheless
wrong claim that a scan (which is merely a way to determine which
services are running on a specific host) would require someone's
permission. Second, you can use nmap in several ways. You may very well
probe one specific service instead of running a full-scale scan. Third,
finding out what causes specific (suspicious) entries in my logs
qualifies very well as network troubleshooting. At least in my book.

There's not only nothing on nmap, but nothing on port-scanners or port-
scanning in general.

Not every ISP has theses statements, and anyone who agrees to conditions
like that deserves what they get. Besides, the terms of an ISP contract
hardly qualify as "legal trouble".

If my ISP would suspend my account because of someone complaining about
a portscan, they'd find themselves in court faster than they can spell
"lawsuit".
