Scapyでは、sr後で分析するためにの出力をディスクに保存したいと考えています。
ans, unans = sr(somePackets)
scapyunansの組み込み関数に問題はありませんが、ディスクwrpcapに保存できないようです。ans
>>> wrpcap(locationOnDisk, ans)
WARNING: PcapWriter: unknown LL type for tuple. Using type 1 (Ethernet)
Traceback (most recent call last):

sec = int(packet.time)
AttributeError: 'tuple' object has no attribute 'time'
実際、私が最も関心を持っているのは、各パケットにtime追加された属性です。sr
だから私はpickleで試しましたが、さらに悪化しました:
>>> pickle.dump(ans, open(locationOnDisk, "w+"))
