Is there any network tools to capture the devices in a network? Ip address and mac address stuff.
For instance, if there is a network without an DHCP server running how to find the DNS, internet gateway and may be computers ...

This can be very handy, since its very hard to try out all the ip numbers with ping test!

If you mean devices connected to your WLAN AP, you may try kismet (though I'm not sure if it's suitable for this task)

Check here:

But the easiest way is just to use nmap with all the ips in your subnet (normally it's just 255 computers maximum).

With nmap you also see what the devices offer (DNS, HTTP, etc.)

Use the nmap which is in extras.

The version in devel and testing has some issues.

autoscan: http://autoscan-network.com/download/maemo/

IDK if it's Maemo5 compatible.

fping is better than ping but although I got it compiled it wouldn't run on Maemo4.

nmap way:
Code:
sudo nmap -O $(netstat -rn | grep UG | awk '{print $2}')/24
EDIT: -O is for OS detection. Don't use this parameter with N810, it will crash Maemo. Use AutoScan instead.
