who is on my network???

Hey,
Okay, it's not actually MY network but another wireless network I came across... I wanna know how I can find out who is on the network and what they're doing, if possible.
After trying various 192.168.x.x combinations I came across the router and found what model it was... I then went to google and found out the default password, so to say the least I'm in the router.
So now from here where do I go? I'm not trying to be mischivous (spelling?) but I wanna see what all I can do. Is there any way to find out who is on the network and possibly see their computer? I live in an apartment complex and I think if I could access some stuff I could find out whose router it is.
Also, there's 2 other wireless networks I can tap into as well, however I am unable to access their router. Is there anything for this scenario?

Look for something like "DHCP Client List" in the router it will give you a rough idea of who is on your network

Sweet! Yeah turns out I'm the only one on the network right now, *shrugs* I aint complaining because my bittorrent is running 3 downloads at about 106kbs each, so... lol

I appreciate the help. What about those other ones that I do not have access to the router?

you could try something like ettercap

Set a scanner to go through the subnet, then you'll find out which systems are online.

Hmmm, that sounds nice... But a scanner, could you name some?

nmap

Okay, I'm trying nmap, but how am I scanning my own network for connections?
Should I run it like this...?

nmap 192.168.1.*

And also, do I have to forward ports and if so which one(s)?

un4given -- a couple things you could try....

Are you in linux? if so do a "ping -b 192.168.1.255

Try nmap -sP -vvv 192.168.1.*

Both of these will return ping echos....

If you wanna do os detection and such, you could try

nmap -sS -vvv- -O -A 192.168.1.*

;)
