Traceroute on IPv6 Network #27

Closed KiritoMiao closed 3 years ago

KiritoMiao commented 3 years ago

Hi, when I try traceroute to any IPv6 address, this lib just put the dst as the only hop. I have turnoff the firewall on this machine.

Command:

Python 3.6.8 (default, Nov 16 2020, 16:55:22) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import icmplib
>>> hops = icmplib.traceroute('2001:470:1:18::115')     
>>> print(hops) 
[<Hop 1 [2001:470:1:18::115]>]

Hi!

Thank you for taking the time to report this issue. It's a great idea to include the tcpdump capture 👍 I think I know where the problem is coming from. I need to do some tests. I will release a fix soon.

ValentinBELYN commented 3 years ago

I just released icmplib 2.0.1 which should fix your problem. Can you try again ? Thanks 😃

KiritoMiao commented 3 years ago

Hello,

It still have some kinds of error that result put only the target's ipv6 in the final hop. I attached the log stuff under this response and hope they can help.

Strange... I have looked at the tcpdumps overall and they look correct. Do you have a firewall activated on your computer?

Can you run the following Python script and give me the result?

from icmplib import PID, ICMPv6Socket, ICMPRequest, ICMPLibError

sock = ICMPv6Socket()

for i in range(1, 15):
    request = ICMPRequest(
        destination='2607:f8b0:4007:80c::200e',
        id=PID,
        sequence=i,
        ttl=i)

    try:
        print(f'[{i}] Request: {str(request.__dict__)}')
        sock.send(request)
        reply = sock.receive(request)
        print(f'[{i}] Reply: {str(reply.__dict__)}')

    except ICMPLibError as err:
        print(err)

sock.close()

Finally, can you provide me with the pcap file created by tcpdump when you run the script? Thanks!

Hello, I have tested on some machines and the pcap/log is attached in the zip file

Data.zip

Hi @KiritoMiao 👋 Happy New Year!

Sorry for the delay. I'm quite busy now. I have analyzed your files and it looks like the socket is failing to get the ICMPv6 error messages used for the traceroute function. However, in your tcpdump captures, we can see these messages. I don't know yet if this is a kernel limitation or not.

I need some time to do my research and testing.

ValentinBELYN commented 3 years ago

Good news! I have found the cause of the problem and I will release a fix this weekend.

This is a problem related to the IPv6 header which is badly handled when the message is not an ICMP Echo Reply.

ValentinBELYN commented 3 years ago

I just released icmplib 2.0.2 which should definitely fix your problem. Can you test?
