```sh
# Create two nodes
$ ockam node create n1
$ ockam node create n2

# Send a message to the uppercase service on node 2
$ ockam message send hello --to /node/n2/service/uppercase
HELLO

# A more verbose version of the above would be,
# assuming n2 started its tcp listener on port 4000.
$ ockam message send hello --to /ip4/127.0.0.1/tcp/4000/service/uppercase
HELLO

# Send a message to the uppercase service on node n2 from node n1
$ ockam message send hello --from /node/n1 --to /node/n2/service/uppercase
HELLO

# Create a secure channel from node n1 to the api service on node n2
# The /service/api is a secure channel listener that is started on every node
# Send a message through this encrypted channel to the uppercase service
$ ockam secure-channel create --from /node/n1 --to /node/n2/service/api \\
