Scapy函数错误"MemoryError“

Question

我想使用rdpcap打开一个流量捕获。

cap = rdpcap("Chall_1.pcapng")

但我收到以下错误，我不知道如何解决它。

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/scapy/utils.py", line 979, in __call__
    i.__init__(filename, fdesc, magic)
  File "/usr/lib/python3/dist-packages/scapy/utils.py", line 1124, in __init__
    RawPcapReader.__init__(self, filename, fdesc, magic)
  File "/usr/lib/python3/dist-packages/scapy/utils.py", line 1035, in __init__
    raise Scapy_Exception(
scapy.error.Scapy_Exception: Not a pcap capture file (bad magic: b'\n\r\r\n')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/valentin/Desktop/Tema3/ctf1.py", line 29, in <module>
    cap = rdpcap("Chall_1.pcapng")

    with PcapReader(filename) as fdesc:

    self.f.read(blocklen - 24)
MemoryError

Answer 1

问题是我的虚拟机上没有合适的RAM。

Answer 2

我从这个Scapy拉请求中推断，rdpcap()能够同时打开pcapng和pcapng文件。如果这不起作用，那么可能是Scapy；请在Scapy问题清单上报告。
