A fellow Maemo member has ported the NetDiscover tool to the N900. See Hawaii's port and download it at: http://www.knownokia.ca/2010/10/quic...r-on-n900.html

Netdiscover is an active/passive address reconnaissance tool, mainly developed for those wireless networks without DHCP server, when you are wardriving or walkwalking with the N900. It can be also used on hub/switched networks (but we don't have a LAN connection on the N900...)

Built on top of libnet and libpcap, it can passively detect online hosts, or search for them, by actively sending arp requests, it can also be used to inspect your network arp traffic, or find network addresses using auto scan mode, which will scan for common local networks.

If anyone has any similar networking or penetration testing tools working on the N900 (outside those tools publicly available on the usual repositories) then please share.
