.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.ps1 11:22:33:44:55:66 192.168.100.100
