I've been playining with nmap, autoscan, telnet and tiny-mtr a lot on my N810 lately and have found a new, and rather unexpected use for my tablet. These 'pen-testing' apps are fantastic to have on your NIT.

Someone linked to an nmap book on Amazon and I actually added it to my 'want-this-for-xmas'-list.

I got two n00bish nmap questions:

1) Last night I found myself at the local Panera coffee shop. They provide free wifi after you accept the terms on a home-page.
There were maybe 5-7 people sitting working/playing on their laptops/smartphones and I wanted to see if I could do a scan of the devices connected to the network - but both nmap (using a nmap -sP 10.0.0.0/24 scan) and autoscan just showed the router and myself.
So, on networks like these - can I ever see the other devices - and if so how?

2) The device I think is the router gave this nmap result:
Using command: nmap -O -sS 10.0.0.0/24

Starting Nmap 4.76 ( http://nmap.org ) at 2009-12-08 19:49 PST
Interesting ports on 10.0.0.4:

I'm particularly curious about the 8081 and 8082 outputs.
Anyone know what these are?
