How do I change the state of the device to UP or DOWN?
The syntax is as follows:
ip link set dev {DEVICE} {up|down}
Nmap
Useful parameters:
netdiscover
Discovers IP, MAC Address and MAC vendor on the subnet from ARP, helpful for confirming you're on the right VLAN at client site
netdiscover -r 192.168.1.0/24
