Dear Developer's,<div><br></div><div><div style>I am doing my master of science thesis at Politecnico di torino, Italy. My thesis concentrates on developing an efficient intrusion detection system for Wireless Sensor Networks. Basically concentrating on the protocols (<b> IEEE 802.15.4, 6LoWPAN </b>and its application level protocol <b>COAP(Http)</b> ) . I have been trying to analyse SNORT and SURICATA ( Both doesnt support decoding these protocols ). Found SURICATA has some better capabilities, hence decided to work with this. But to start with I have some problems.</div>
<div style><br></div><div style>Problem:</div><div style><ul><li style="margin-left:15px">Currently I have an sensor node which sniff the IEEE 802.15.4 traffic and forward them to a virtual Interface ( TUN/TAP ). </li><li style="margin-left:15px">
I tried to run Suricata on that interface , I got the error</li></ul></div><div style><blockquote class="gmail_quote" style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

<li style="margin-left:15px">Wireshark can dissect almost all the protocols which I need. Is there any way we can use it for developing decoder for Suricata?</li></ul><div>It would be a great help for me to start and contribute for this opensource community through my thesis.</div>
