I was working on Centos and getting familiar with yum and I would like to know how to know which devices are connected to my network and see their respective IP and Mac address... Any ideas?
To 'scan' the network you can:
ping6 -n2 ff02::1%eth0.
[Edit] This is not a complete list. But it should help you get started.
Using nmap a lot of info can be regarded..
nmap -A -v -v 192.1680.0/24 gives a lot of information, even SO in some cases
nmap -sP 192.168.1.0/24 gives the MAC and IP adresses. Very Usefull too
sudo nmap -PU 192.168.1.0/24 explains every ip
