Re: IPSec on Linux Kernel

Hi,Fabio,

  - Assuming that you intend to deal with IPV4, I suggest that you will
start by looking at the ah4.ko module sources, which are in net/ipv4/ah.c,
especially at the ah_output() and the ah_input() methods.

(for ipv6 there are the ah6.c in net/ipv6).

- May I ask: are you aware that the Authentication Header protocol deals
only with authentication and not with encryption? and as a result, the ESP
protocol, which supports authentication and also, when needed, encryption, is
much more widely used?
