Network disconnect is introduced by removing default gateway, easily reversible condition. On my local machine it takes 30 seconds for peers to reconnect after connectivity is restored. As you guess this is not an accident, and there is 30 seconds timeout for dial expiration. This dial expiration is used in p2p.Server to guarantee that peers are not dialed too often. Additionally I added small script to Makefile to run such tests in docker environment, usage example: ``` make docker-test ARGS="./t/destructive/ -v -network=4" ```

// Package netlink provides a simple library for netlink. Netlink is

// the kernel. It can be used to add and remove interfaces, set up ip
|
|
// addresses and routes, and confiugre ipsec. Netlink communication
|
|
// requires elevated privileges, so in most cases this code needs to
|
|
// be run as root. The low level primitives for netlink are contained
