[Rohan-Kar]

I have tried some command to create remote connection in server side i have tried
server side
`
python3 -m http.server --bind 127.0.0.1 5000

ockam node create server_sidecar
ockam tcp-outlet create --at /node/server_sidecar --from /service/outlet --to clientip:5001`

and client side
`ockam node create client_sidecar

ockam secure-channel create --from /node/client_sidecar --to serverip:5001
| ockam tcp-inlet create --at /node/client_sidecar --from 127.0.0.1:7000 --to -/service/outlet
`
but in client side second command getting error . error: invalid value 'serverip:5001' for '--to ': unregistered protocol prefix . Please guide me .

Hi @Rohan-Kar can you please try without a - in front of /service/outlet in --to -/service/outlet?

@etorreborre Thanks for the guidance i check with the the command
ockam secure-channel create --from /node/client_sidecar --to serverip:5001 getting error this line error: invalid value 'serverip:5001' for '--to <ROUTE>': unregistered protocol prefix "serverip:5001"

The - in front of /service/outlet is required, it represents the output from the command before the pipe. The secure-channel create command outputs a route to the secure channel. So -/service/outlet represents: route to the outlet via the secure channel that was created in the previous command.

@Rohan-Kar the --to value has to be an Ockam Route to another Ockam node's secure channel listener, it can't be just ip:port. Here'a a full example you can try https://docs.ockam.io/#quick-start

@Rohan-Kar please let us know in case the quick start example doesn't work for you.
