Linux code
=====================
Note: pfdump and other ProtocolFilters samples require package nss_tools (or libnss3-tools) for importing root certificate to mozilla storages.

linux - Linux version of filtering tools.
linux/help - API manual
linux/nfproxy - Linux version of filtering API.
linux/samples - sample applications.
passthrough - filters all TCP connections in raw packets mode.
pfdump - filters TCP connections and saves classified objects to *.bin files in the same folder.

The connections are redirected using iptables to local proxy bypassing root connections. 
Thus it is necessary to run the code with root privileges.
Also pfdump requires root rights to import certificates to all user profiles inside /home.

Building Linux code:
cd unix/linux
make

The binaries are copied to unix/linux/build.
