# To execute this run script on a development PC, you need to setup a TAP device
# first:
# netdev=wlp2s0
# tapdev=tap0
# user=developer
#
# sudo ip tuntap add dev $tapdev mode tap user $user
# sudo ip address flush dev $tapdev
# sudo ip address add 10.0.2.1/24 brd 10.0.2.255 dev $tapdev
# sudo ip link set dev $tapdev addr 02:00:00:ca:fe:01
# sudo ip link set dev $tapdev up

# connect using your favorite grpc client
