The first thing a hacker does when he goes to a coffee shop is connect to the network and ifconfig and see what dhcp gave him. If his IP is something like 192.168.9.105, then he has an idea of the network range and then will attempt a host discovery. He will first try the default -sS nmap option just to look for low hanging fruit. If anything shows up with -sS or -sT then he knows those might be easier targets. If nothing appears then he steps up his scans. Nmap is the premier open source scanner. There was a tut about it posted on this site and thats how I found this place from slashdot, but now its gone. No worries because there are many free nmap tuts out there. Make sure its free, I saw this one dude trying to sell the "secret" of nmap and thats total bs. The only secret is to download and start working with it and not just read about it!
