What you can do is have your program listen to a local port and then redirect traffic to this local UDP port 53. If you have a DNS server listening on this port, you're done. This is a basic stup for transparent proxying. -- 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
