.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 MACaddress
Specifies the host's MAC address (e.g. 11:22:33:44:55:66)
.PARAMETER IPaddress
Specifies the host's IP address or subnet address (e.g. 192.168.0.255)
.PARAMETER Port
Specifies the UDP port (9 by default)
.PARAMETER NumRetries
Specifies number of retries (3 by default)
.EXAMPLE
PS> ./wake-up.ps1 11:22:33:44:55:66 192.168.100.100
