Then, if you only need parameters, but no action on packet, you can use ULOG target : http://gnumonks.org/projects/project_details?p_id=1 You can write your own "listener" and have it listen to ulog socket. Or you can send packet to userland using QUEUE target, treat it with your own application and maybe reinject it. You can find sample code at : http://gnumonks.org/projects/project_details?p_id=3 http://gnumonks.org/projects/project_details?p_id=2 -- Cédric Blancher <blancher@xxxxxxxxxxxxxxxxxx> IT systems and networks security - Cartel Sécurité Phone : +33 (0)1 44 06 97 87 - Fax: +33 (0)1 44 06 97 99 PGP KeyID:157E98EE FingerPrint:FA62226DA9E72FA8AECAA240008B480E157E98EE
