set up a rabbit mq server on a remote server named openwrt

docker run -d --name rabbitmq -p 5672:5672 -p 15672:15672  rabbitmq

set up port forward on windows

inspired by remote port forward on VSCODE

ssh -L 5672:127.0.0.1:5672 openwrt -N -v -v

access rabbit mq server as if it is on windows

then run Send.java

switch back to Recv.java
