trt-scapy.py - v0.0
===================

  Another implementation of the  M.  Zalewski  0trace  tool  which performs hop
enumeration within "established" TCP connections. Trt-Scapy  is  based  on  the
Scapy tool (http://secdev.org/projects/scapy/)  from  P.  Biondi  and  performs
enumeration for TCP "established"  connections and UDP DNS requests streams.
Refer to the original http://lcamtuf.coredump.cx/soft/0trace.tgz.

TCP to www.ebay.com on the TCP 80 port and  ttl  game  with  0trace  (refer  to
