netdiscover - scan your local area network (LAN) [and wifi too!] like years ago.

Really usefull tool, available since I can renember... its location, and one of my usernames!

:)

now what has to be taken in consideration: this program used to ba available to root user by default but, for security reasons i presume, path to this folder was not set so to run without the / bedore command. If you want to "walk on the wild side of life", this not to be taken but as a joke please, you can

export PATH=$PATH:/usr/sbin

to run it from anywhere. Any path can be added to suit your need.
