* Tunnel internal NTP traffic through IPSec.Guilhem Moulin2016-05-221
| | | | | | | More precisely, between our NTP-master (stratum 1) host and the other machines (all stratum 2). Providing authentification and integrity for internal NTP traffic ensures a consistent time within our internal infrastructure.
* Set up IPSec tunnels between each pair of hosts.Guilhem Moulin2016-05-221
| | | | | | | | | | | | | | | We use a dedicated, non-routable, IPv4 subnet for IPSec. Furthermore the subnet is nullrouted in the absence of xfrm lookup (i.e., when there is no matching IPSec Security Association) to avoid data leaks. Each host is associated with an IP in that subnet (thus only reachble within that subnet, either by the host itself or by its IPSec peers). The peers authenticate each other using RSA public key authentication. Kernel traps are used to ensure that connections are only established when traffic is detected between the peers; after 30m of inactivity (this value needs to be less than the rekeying period) the connection is brought down and a kernel trap is installed.
