发送数据包时未找到默认路由（scapy）

Question

this is my error

I need help in this.No route found (scapy) error

Answer 1

The no route found message is a warning not an error. This should not be a problem anyway since you're trying to send to 127.0.0.1. The exception raised is a PermissionError . That's because sending the packet requires the administrator privilege. On a unix like system you must be logged as root to do this. This is what I get on my Linux:

>>> send(IP(dst='127.0.0.1'), return_packets=True)
.
Sent 1 packets.
<PacketList: TCP:0 UDP:0 ICMP:0 Other:1>
