问题描述

大家好，我是新来的，所以请善待。

Hello everyone i am new here so please be kind.

我最近一直在使用scapy，以便向选定的启用ipv6的服务器发送和接收ipv6数据包。代码的要点在这里：

I have been using scapy lately in order to send and recieve ipv6 packets to selected ipv6 enabled servers. The gist of the code is here:

text = line[:-1]
            #destination=getIPv6Addr(line[:-1])
            destination="2607:f1c0:1000:60e0:7992:97f7:61b2:2814"
            source="2001:630:d0:f105:5cfe:e988:421a:a7b7"
            syn = IPv6(dst=destination,src=source) / TCP(sport=555,dport=80,flags="S")#flag S is syn packet
            syn.show()
            syn_ack = sr1(syn,timeout=11)

当我执行代码时，这个是我得到的：

When i execute the code hoever this is what i get:

Begin emission:
Finished to send 1 packets.
.................WARNING: No route found for IPv6 destination :: (no default route?)
WARNING: No route found for IPv6 destination 2607:f1c0:1000:60e0:7992:97f7:61b2:2814 (no default route?)
............................................................................................................
Received 1322 packets, got 0 answers, remaining 1 packets

根据我的理解，数据包已经发送，但是从未得到响应（0个答案）。这让我想到使用wireshark来嗅探数据包。

From what i understand, the packet has been sent nevertheless a response is never gotten(0 answers). This made me think of using wireshark to sniff the packet.

与过滤器一起使用时：

ip6 net 2607:f1c0:1000:60e0:7992:97f7:61b2:2814

我意识到数据包从未发送过第一名！有谁知道为什么会发生这种情况或者在这里发生什么？

I realised the packet was never sent at the first place! Does anyone know why this is happening or what is hapening here?

问候

编辑：

通过评论仔细检查，我意识到路线列表不应该是空的。没有路由发送数据包。我不知道如何添加它们！请帮助我做的是：

On closer inspection from comments, i realized that the route list SHOULD not be empty. There are no routes to send the packet. I am not sure how to add them! Please help here is what i did:

我试图从我的设备获取所有接口。以下是我的回复：

i tried to get all the interfaces from my device. Here is what i got back:

如你所见，那里没有ipv6地址。如果没有列出ipv6地址，我该如何发送ipv6数据包？在extend中，这是来自cmd的ipconfig：

As you can see, nowhere in there there is an ipv6 address. How am i supposed to send ipv6 packets if no ipv6 address is listed? in extend, here is the ipconfig from cmd:

    Ethernet adapter Local Area Connection 4:

   Connection-specific DNS Suffix  . : ecs.soton.ac.uk

这是在VM上运行但我不认为这很重要。

This is run on a VM but i dont think it matters.

请有人帮助我这非常重要！如何配置scapy以了解如何发送ipv6数据包。为什么我在接口列表中看不到ipv6地址？

PLEASE someone help me this is very important! how can i configure scapy in order to understand how to send ipv6 packets. and why do i see no ipv6 addresses in the list above of interfaces?
