I'm not able to use Nmap due to my ISP's terms of service

Well I'm trying to learn to use Nmap but my isp doesn't allow portscanning as it goes against the terms of service. I was wondering if anyone has had the same problem and if they had found a way around it? I was also wondering if i can at least run metasploitable 2 on virtual machine and still use nmap without any problems?

I would say to give this article a read...has some good info.

https://nmap.org/book/legal-issues.html

Also this article takes into account the legality of port scanning: https://www.sans.org/reading-room/white ... canning-71

I would say depending on where you live, it can be questionable, but not necessarily illegal. It's sort of in that gray area of U.S. law.

What does the TOS say exactly about port scanning? Do they mention just their servers specifically or just using it in general? I don't believe they could tell you were using nMap to do scans but i'm not 100% on that.

Last but not least, you might look into nMap idle scans (https://nmap.org/book/idlescan.html) and if possible, get permission from the owner of the server your scanning =P

Terms of service violations are bullshit under the CFAA aren't they?

Scanning your system shouldn't be a problem.

As genghis_ hinted at; the ISP's terms of service only applies to things outside your network. If you run Metasploitable in a virtual machine on your computer or even if you run it in your own network and scan it there only, it's not a violation. Almost anything you would do circumventing the restriction on the public network could be seen as a violation, you'll have to make your own choice if you're willing to bet the gray legal area (depending on where you live) is safe enough for you.

Easiest way around is just use Starbucks or something internet, provided they are not constricting things such as that. There are also always VPNs. Side note: I'm not recommending you break laws. I have no earthly idea how legal/illegal this is. It seems pretty gray area. It just depends on why you are port scanning I guess.

This is grey area, but making fake names on facebook and logging into a cafe's free unsecured WiFi from outside can put you in jail, so there are some laws not worth following. Decide on your own ethics. I wouldn't take a risk though.

That depends entirely on what you see or agree to when connecting to the network. I doubt if anyone ever monitors the traffic of some of the smaller businesses though.
