[Fedora Core 4 (kernel 2.6.17)] I am interested to understand whether the IPsec implementation outputs any log information. I am particularly interested in any log output under conditions of replay attack. I have simulated a replay attack (using ethereal and tcpreplay) - I noted that the incoming ping packets were ignored, but I could find no log of the 'replay attack'. I looked in the syslog, but perhaps I am looking in the wrong place - or maybe there is a kernel option that needs to be enabled.
I understand that IPsec is implemented in the kernel - I'm struggling to find any documenation that might describe the function of the IPsec implementation (e.g. regarding logging, configuration etc.). Perhaps someone could point me in the right direction.
Thanks, Richard
