# PeerTester

Test your DN42 peers by sending packets with the random source IPs ``172.20.0.53`` / ``fd42:d42:d42:54::1`` and your host's IP as destination IP.

Works on layer 3 (tun) interfaces. The application automatically sends test packets on all interfaces by default.

This will test:

- Forwarding setup of your peer

- Peer's installation of routes received via BGP

- Misconfigurations of your peer such as NAT

- Unexpected forwarding paths (via TTL measurements)

- State and latency of the tunnel

## Important setup notes

- The `dst4` and `dst6` IP addresses should be announced via BGP and *not* be IP addresses used for the peer tunnels.

- If the status of a peering is not shown as `OK` for either IPv4 or IPv6, then the latency values returned are invalid and informational only.

## Usage

````

Usage of ./peertester:

  -daemon

        run as a daemon and accept interface lists via unix socket

  -dst4 string

        destination IPv4 address (the address this host can be reached from) or CIDR to find address from 'lo'

  -dst6 string

        destination IPv6 address (the address this host can be reached from) or CIDR to find address from 'lo'

  -interface string

        optional comma-separated target interface(s). Use '-' to read from stdin. If not specified, packets are sent on all interfaces

  -json

        output as JSON
