    Hi
    I have a query regarding socket programming . im trying to create a
    dummy IPSec (ESP)header Packet . My Packet looks like
    <code>
    struct mypkt
    {
      struct iphdr ip;
      struct _myesp esp;
      struct tcphdr tcp;
    };
    and
    struct _myesp {
      u_int32_t esp_spi; /* ESP */
      u_int32_t esp_seq; /* Sequence number */
      u_int32_t esp_iv; /* Sequence number */
      u_int8_t esp_padsize;
      u_int8_t esp_next;
      u_int32_t esp_ah; /* Sequence number */
    };
    </code>

    But the problem is that when i send a socket using RAW socket , in
    ethereal it shows IP -ESP ONLY . doesnt shows up the TCP header .
    while testing a Normal IPSec implementation shows up all three layers.

    Lemme know if i should paste complete code.
    Any help is appreciated
    Thanks
    Bob
