Problem with tracepath #2

Closed standa4 closed 7 years ago

standa4 commented 7 years ago

Hello,

when i try to trace the path to honeypot with use of tracapath command the honeyd returns the following error: 2017-06-05 11:57:22,526 Exception: Cannot send reply packet: send: Message too long Traceback (most recent call last): File "/opt/honeyd-python/honeyd/core/dispatcher.py", line 256, in icmp_reply self.pcapy_object.sendpacket(reply_eth.get_packet()) PcapError: send: Message too long

Can you look at it what could be the problem. Thank you.

Hi @standa4,

it seems that packets were not truncated properly and this resulted in replies larger than pcapy allows. Should be fixed in the 10e42dd commit. I'd like to mention that for tracepath to terminate the UDP ports should be configured to filtered state, as this behavior replies with the expected ICMP error message.
