Most modern systems have WOL (Wake On LAN). Here is some Python code
that will do WOL.

# Wake-On-LAN

import struct, socket

def WakeOnLan(ethernet_address):
  '''
  Example usage: WakeOnLan('0:3:93:81:68:b2')
  '''

  # Construct a six-byte hardware address

  addr_byte = ethernet_address.split(':')
  hw_addr = struct.pack('BBBBBB', int(addr_byte[0], 16),
    int(addr_byte[1], 16),
    int(addr_byte[2], 16),
    int(addr_byte[3], 16),
    int(addr_byte[4], 16),
    int(addr_byte[5], 16))

  # Build the Wake-On-LAN "Magic Packet"...

  msg = '\xff' * 6 + hw_addr * 16

  # ...and send it to the broadcast address using UDP

  s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
  s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
  s.sendto(msg, ('<broadcast>', 9))
  s.close()
# End of code #

This would only work on the same network so if you're not, it's more
complicated. A low-tech way of doing it is to use a hardware device that
can be controlled via TCP/IP or even DTMF (telephone). I have a power
controller device that will listen for certain DTMF tones and either
power on or power off the unit that is attached to it.
