How to stream multicast from pcap file (automation)

I have 3 pcap files - UDP, RTP and RTP with FEC. The last one means that I have 3 sockets that have to go at the same time for error correction.

I tried to use tcpreplay but it doesn't work if streamed inside of 1 machine which is the purpose. Docker won't work because of the same problem, virtualization could work but the Linux kernel I'm working with makes a huge problem so I'm looking for another tool like tcpreplay that would stream to localhost.

Solution

  • bittwist uses the same lib under the hood as tcpreplay. The actual solution was:

    sudo sysctl -a | grep "\.rp_filter" | awk '{print $1 "=0"}' | xargs sudo sysctl
