I am in a LAN and there are 3 Ubuntu, 2 Kubuntu, 2 Windows XP and 2 Windows 7. What commands or tools are available to see what PCs are connected to the LAN that it shows the name of the PC and the IP. Similar to tools like Angry IP that show all PCs in a LAN.
Note that I do not know the IPs or names of the computers connected to the LAN. So the tool or command should look for them to.
