Simple tcpliveplay test #540
Comments

Thanks for outlining the problem. I'm labeling this as a bug for now, but will not assign to myself. Tcpliveplay was developed through a Cisco project before I was involved in Tcpreplay. I'll see if I can find the original author and see if he is interested in maintaining this code. If not, I'll either have to dive into it myself, get another volunteer to step in or make some drastic decisions about the future of Tcpliveplay. |

Thanks a lot for the quick replay. |

I would suggest trying tcpliveplay version 3.4.4. I think that was the last version touched only be original developer. Mainly security fixes have gone in since then. If it does work for you, let me know and I can do |
|
Thanks! I'll check and let you know. |

The Ubuntu tcpreplay package version 3.4.4-2+deb8u1build0.16.04.1 doesn't have the tcpliveplay file.

@riramar my mistake. I started maintaining (and now own) 4.0.0 and didn't realize that tcpliveplay was not distributed with 3.4.4. I am now the lone maintainer of Tcpreplay and don't know the entire history of Tcpliveplay. I'll ask the previous maintainers what version it was supported. I suspect support was dropped before 3.4.4, but the source code was not in the release tarballs. I may have to drop it as well, unless I can fix this bug. Sorry, I don't know of an alternative. I think I saw something once in GitHub, but I cannot remember where. |

No problem @fklassen ... I really appreciate your quick replies. |

I am having the exact same issue on Kali with this version:
Is there any news to this topic? @riramar did you solve the situation for yourself? Thanks a bunch! |

I have just downloaded and built the latest version from github and fail also with the other available injection methods:
and
Here is the output of one run:
What I can see in a parallel wireshark session is, that my machine is sending out a TCP SYN packet and the server is responding with a SYN ACK. No ACK is given by my machine. After a few seconds, the server resends the SYN ACK a couple of times. Finally the program aborts, claiming that the server did not respond. Opening a TCP session with telnet to the same port works just fine. There are no iptables rules, except for the one suppressing the RST from the kernel, as per tcpliveplay documentation. Kernel version is 5.4.0-kali2-amd64. |

I discussed with an early maintainer, and unless we find a volunteer to take on |
I'm trying a simple test with tcpliveplay but it seems tcpliveplay doesn't handle TCP handshake properly.
Let me describe the steps from my testing.
# tcpdump host 104.31.95.22 -n -s 65535 -w http.pcap# curl http://104.31.95.22Could you please help me to perform this simple test?
Thanks!
