.SYNOPSIS
Wakes up a computer using Wake-on-LAN
.DESCRIPTION
This PowerShell script sends a magic UDP packet to a computer to wake him up (requires the target computer to have Wake-on-LAN activated).
.PARAMETER macAddr
Specifies the host's MAC address (e.g. 11:22:33:44:55:66)
.PARAMETER ipAddr
Specifies the host's IP address or subnet address (e.g. 192.168.0.255)
.PARAMETER udpPort
Specifies the UDP port (9 by default)
.PARAMETER numTimes
Specifies # of times to send the packet (3 by default)
.EXAMPLE
PS> ./wake-up-host.ps1 11:22:33:44:55:66 192.168.100.100
✅ Magic packet sent to IP 192.168.100.100, UDP port 9, 3x - wait a minute until the computer fully boots up.
