   tags: network/vpn/wireguard, observability/logging, programming/go

   [ permalink ]

   Wirelogd relies on the latest handshake to determine if a peer is active or inactive. While there is trafic the handshake should be renewed every 2 minutes. If there is no trafic handshake is not renewed. Based on this behavior we assume that if there is no new handshake after a while, the client is probably inactive.

    tags: cloud-computing, cloud-computing/aws, network, network/firewall, network/ip

    [ permalink ]

    Use case:

    • Set up an AutoScaling Group with exactly 1 min/max/desired instance
    • Attach an Elastic IP to the active instance

    Usually for interoperability reasons and/or IP-based network rules (80's firewall anyone?).
