<p>Hi,</p>
<p><br>
</p>
<p>I Just did ..</p>
<p><br>
</p>
<p>pfring_open("<font color="#ff0000">eth0, eth1</font>"...)..OK</p>
<p>pfring_set_direction(rx_and_tx_direction) .. OK (not sure if I
actually needs this one)<br>
pfring_set_socket_mode(send_and_recv_mode) ..OK <br>
</p>
<p>pfring_enable_ring() .. OK</p>
<p>pfring_recv(blocking) .. I'm getting packets from the interfaces</p>
<p><br>
</p>
<p>However,<br>
</p>
<p>When I try to send data using pfring_send() I'm getting -1.</p>
<p>Note that my little test is actually sending the same packet that
was received from pfring_recv()</p>
<p>Not very smart but its just a test :)</p>
<p>Kernel module parameters : min_num_slots=65536
enable_tx_capture=0<br>
</p>
<p>What did I do wrong ?</p>
<p><br>
</p>
<p>And if it was sending successfully, through which interface would
it be sending from?</p>
<p>Since I was open multiple interfaces using pfring_open()</p>
<p><br>
</p>
<p>10x</p>
