Create a local fleet for tests

Installation

The following software is required:

• jq
• docker
• docker-compose
• qrencode

Be sure that NAT is configured in the router you're connected to, since this uses the external IP address to connect the peers

Usage

go run main.go

By default it will attempt to create 1 bootnode, 1 mailserver and 1 whisper node. You can control the number of mailservers and whisper nodes by using the flags --mailservers N and --whisper N, where N is the number of nodes to create.

WARNING this will overwrite the following files:

• fleets.json
• vendor/status-go/services/mailservers/fleet.go

The program will create the required nodes, and modify the fleet files. Afterwards you need to rebuild status-go and status-desktop, so it uses the local fleet nodes instead of the default eth.prod nodes.

Once you're done with the fleet, press CTRL+C to shutdown the fleet

Simulating network conditions

With https://github.com/tylertreat/comcast, you can test common network problems. Use the following command to setup some rules:

comcast --device=wlp2s0 --latency=250 --target-bw=1000 --default-bw=10000 --packet-loss=10% --target-addr=your_ip_address --target-proto=tcp,udp --target-port=30310:30320

latency is specified in milliseconds, target-bw and default-bw are in Kbit

Replace the device flag with a valid value from ifconfig and target-addr with your IP address. After you're done with testing, use:

comcast --device=wlp2s0 --stop
