pickle.PicklingError: Can't pickle<br>:...

python-nmap 0がインストール.14後、簡単なテストの実行に失敗しました.

pickle.PicklingError: Can't pickle <function scan_progressive at 0x01C255B0>: it
's not found as nmap.nmap.scan_progressive

コードは次のとおりです.

import nmap
nma = nmap.PortScannerAsync()

def callback_result(host, scan_result):
    print '------------------'
    print host, scan_result

nma.scan(hosts='192.168.18.0/24', arguments='-sP')

while nma.still_scanning():
    print("Waiting ...")
    nma.wait(2) 

最初はコードが間違っていると思っていたが、nmapインストールディレクトリのexampleを見つけた.py実行、同じエラーが発生しました.追跡を繰り返した結果、pickleで発見された.pyファイル745行にエラーが投げ出されました.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\opt\Python27\lib\site-packages
map
map.py", line 413, in scan
    target=self.scan_progressive,
AttributeError: 'PortScannerAsync' object has no attribute 'scan_progressive'

それからnmapのソースnmapを読みます.py、やっと402行で、方法scan_progressiveはscanメソッドの内部に定義され、pickleが失敗した.
解決方法:
メソッドScan_progressiveは外に定義し、nmap.py 413行から

target=scan_progressive,

から次のように変更されました.

target=self.progressive,

でいいです.
