This directory contains several helper tools mentioned in ../README: p0f-sendsyn.c - a tool for gathering new SYN+ACK signatures p0f-sendsyn6.c - the same, for IPv6 destinations p0f-client.c - simple API client tool for p0f -s mode Note that IPv6 addresses need to be passed to the utilities in a fully-expanded form (i.e., no ::). To build any of these programs, simply type 'make progname', e.g.: make p0f-sendsyn If that fails, you can drop me a mail at lcamtuf@coredump.cx.
