I need to run this CSA in order to gain access to the network. I don't
trust the network much either, but I am always using OpenVPN, which I
trust completely. Currently I can access the network, and ergo my vpn
without this, but after the 26th that all changes.

I will definitely look into grsec but it seems complicated. Regardless I
require a viable solution and I will take the steps necessary,
regardless of complication.

Is there a way to try and trace what the binary wants to do? I'm aware i
could run strace on it and ethereal to capture what it transmits... But
is there more I can do?
