[Python-es] Causa de este error en un server en python

[Horacio]

Buenas para probar ciertas páginas, tengo un server http simple hecho
en python que atiende en el puerto 8080 con este código...
---------------------
webdir = '.'   # where your HTML files and cgi-bin script directory live
port   = 8080    # http://servername/ if 80, else use http://servername:xxxx/
host = "xxx.yyy.zzz.www"

import os, sys
from BaseHTTPServer import HTTPServer
from CGIHTTPServer  import CGIHTTPRequestHandler

if len(sys.argv) > 1: webdir = sys.argv[1]             # command-line args
if len(sys.argv) > 2: port   = int(sys.argv[2])        # else default ., 8080
print 'webdir "%s", port %s' % (webdir, port)

# hack for Windows: os.environ not propagated
# to subprocess by os.popen2, force in-process
if sys.platform[:3] == 'win':
    CGIHTTPRequestHandler.have_popen2 = False
    CGIHTTPRequestHandler.have_popen3 = False          # emulate path after fork
    sys.path.append('cgi-bin')                         # else only adds my dir

os.chdir(webdir)                                       # run in HTML root dir
srvraddr = (host, port)                                  # my
hostname, portnumber
srvrobj  = HTTPServer(srvraddr, CGIHTTPRequestHandler)
srvrobj.serve_forever( )                                # serve
clients till exit


--------------------
El mismo está en un servidor con ip pública,,, cada tanto veo esto en
los log que devuelve...

A que se debe, como lo puedo corregir? o es una respuesta a un atacante?
