Hi,

I am trying to write a simple app, that will intercept all connection  
creation/close (any TCP connection and hopefully also any UDP  
reception/emission).

I tried simply copying examples (I'm on Ubuntu 14.04 x64 with a 3.13-032  
kernel) like this one :

https://git.netfilter.org/libnetfilter_conntrack/plain/utils/conntrack_events.c

However, when I launch it (using sudo so it's as root) and then create a  
tcp connection (to localhost using telnet, confirming the connection was  
created), nothing shows up.

What am I missing ? Do I need to enable auditing in the kernel/iptables  
somehow ?

Thanks,

Hassan
