如果没有收到数据包，如何告诉 scapy sniff() 函数停止？ 我正在使用 sendp() 函数发送数据包 示例:发送 DHCP Discover 时没有发送响应。
最佳答案
Scapy 中的sniff() 函数有一个超时参数。您可以提供以秒为单位的超时。
您可以通过打印 sniff.__doc__ 找到其他选项。
rypeck@laptop:~$ scapy
>>> print sniff.__doc__
Sniff packets
sniff([count=0,] [prn=None,] [store=1,] [offline=None,] [lfilter=None,] +
L2ListenSocket args) -> list of packets
count: number of packets to capture. 0 means infinity
store: wether to store sniffed packets or discard them
prn: function to apply to each packet. If something is returned,
it is displayed. Ex:
ex: prn = lambda x: x.summary()
lfilter: python function applied to each packet to determine
if further action may be done
ex: lfilter = lambda x: x.haslayer(Padding)
offline: pcap file to read packets from, instead of sniffing them
timeout: stop sniffing after a given time (default: None)
L2socket: use the provided L2socket
opened_socket: provide an object ready to use .recv() on
stop_filter: python function applied to each packet to determine
if we have to stop the capture after this packet
ex: stop_filter = lambda x: x.haslayer(TCP)
