the only difficult thing should be that... how can i say... let me make a little drawing...

                                         +---------+
                                         | payload |
                                         +---------+

                           +-------------+---------+
                           | tcp options | payload |
                           +-------------+---------+

 +-------------------------+-------------+---------+

 | TCP header (fixed part) | tcp options | payload |

 +-------------------------+-------------+---------+

to do this the simpler way is to...

   libnet_build_tcp_options()
   libnet_build_tcp() <---------- here you use the payload

and between the TCP (fixed part of the) header and the payload there will appear the options... the tcp header will have the correct data offset value. :)

please correct me if i am wrong
i've prepared some powerpoint slides that amongst different things also speak about this thing... hope i'm right ;) sorry they are in Italian but graphics and source code are in english as well as soon as i've done them all i'll send a link to Mike they are no good documentation since they are in .ppt but hope that may help building the new documentation cheers
