NAME

wakeonlan - Perl script to wake up computers

SYNOPSIS

wakeonlan [-h] [-v] [-i IP_address] [-p port] [-f file] [[hardware_address] ...]

DESCRIPTION

This script sends 'magic packets' to wake-on-lan enabled ethernet adapters and motherboards, in order to switch on the called PC. Be sure to connect the NIC with the motherboard if neccesary, and enable the WOL function in the BIOS.

The 'magic packet' consists of 6 times 0xFF followed by 16 times the hardware address of the NIC. This sequence can be encapsulated in any kind of packet. This script uses UDP packets.

OPTIONS

-h

Displays the help information.

-v

Displays the script version.

-i ip_address

Destination IP address. Unless you have static ARP tables you should use some kind of broadcast address (the broadcast address of the network where the computer resides or the limited broadcast address). Default: 255.255.255.255 (the limited broadcast address).

-p port

Destination port. Default: 9 (the discard port).

-f file

File with hardware addresses of wakeable computers. For an example check the file lab001.wol in the examples subdirectory.

EXAMPLES

Using the limited broadcast address (255.255.255.255):

    $ wakeonlan 01:02:03:04:05:06
    $ wakeonlan 01:02:03:04:05:06 01:02:03:04:05:07

Using a subnet broadcast address:

    $ wakeonlan -i 192.168.1.255 01:02:03:04:05:06

Using another destination port:

    $ wakeonlan -i 192.168.1.255 -p 1234 01:02:03:04:05:06

Using a file as source of hardware and IP addresses:

    $ wakeonlan -f examples/lab001.wol
    $ wakeonlan -f examples/lab001.wol 01:02:03:04:05:06
