Speaking of open computers, I can see a bunch of networks from my apartment, but only two are strong enough to connect to. One is encrypted, presumably someone in my building. The other is a wireless internet service at the apartment complex across the street.

They have it set up where you can join the network, but you need a username and pass to access anything but the login page and a handful of other homepages. I don't have an account, but I can see dozens of Windows File Sharing computers over it. Speaking of accounts, the network isn't encrypted, and the login page isn't SSLed. Bet I could sniff a few passwords if I cared to try... ;)

Use windows messaging?
 

You could try the Windows messenger service. It may be turned off though if they find popup messages to be annoying (likely).

In terminal type:
replace IP_Address with the IP of any machines you find on the wireless network.

I tried this to connect to my XP machine (which is not wireless) and i couldn't get it to work. Typing the exact command you gave me causes the terminal window to enter into what appears like an infinite loop. I can stop the process by hitting ctrl-c.

After studying the man pages for smbclient, it appears that I need more command options, but there are so many, that I can't figure out what to do with it.

I tried again after turning off my firewall. The process ended simply giving the error message "session request failed."

Print out in great big letters:

"Your Wireless Network Is Not Secure"

and tape it on the wall near the elevator.
