ping with tcpflow and tcpdump

When I use tcpflow icmp and ping I have no answer, but when I use tcpdump icmp aand ping I'm getting answer. Is something wrong with my tcpflow configuration or it should be like that?

Solution

  • When I use tcpflow icmp and ping I have no answer

    Uh... How about this: tcpflow captures data from TCP connections and ICMP messages (e.g., pings & etc) are not part of TCP connections.
