Capability exchange.

[Shubham-dash]

Hi @michalvasko I am having doubt on capability exchanging which are listed below :

1.) While I am connecting netopeer2-cli to netopeer2-server what changes/modifications to do so that I can get a hello message along with capability exchanging.As When we read netconf document they suggest that after connection hello message will exchange by client and server with their capabilities.

2.)Also, I am checking capabilities with the status command on netopeer2-cli side as shown below, so can u tell me the capabilities I am getting on the client-side those are of server or client.

**BUT** I am not sure that above listed lines are capabilities ? if yes then these capabilities are of server or of client 

[michalvasko]

1. Hello message includes the capabilities, they are generally the same thing (one includes the other).
2. Client should advertise only capabilities

urn:ietf:params:netconf:base:1.0
urn:ietf:params:netconf:base:1.1

based on what protocol version it understands, no others. So the capabilities you see are server capabilities.

[Shubham-dash]

@michalvasko Can you tell me how to enable the capabilities exchange during connection?

[michalvasko]

What do you mean? Capability exchange is just hello message exchange, which is a mandatory initial step of every NETCONF session, it is always "enabled".

Hi @michalvasko We are not getting messages on connecting with netopeer2-server at netopeer2-cli side

[michalvasko]

You will need to include much more details and ideally some server/CLI output as well.

I am running server command and connecting through client below are the logs :

As you can see here we are not getting any hello message or capability exchange.

[michalvasko]

Like I said, hello message is exchanged but there are no messages printed. The command status, which you have used before, prints the capabilities received from the server.

[Shubham-dash]

okay, I am getting all the capabilities using status command but please confirm through status command client capabilities can be seen or not . If not then what is the step to get client capabilities.

[jktjkt]

What do you need the client capabilities for?

[Shubham-dash]

@jktjkt actually for verifying purpose that what are the capabilities client and server both exchanging.

[michalvasko]

You cannot see client capabilities on the server but they are not really interesting, that is why. The client is supposed to send only the list of supported NETCONF versions, which are always 1.0 and 1.1 in this case.

[jktjkt]

In that case just activate verbose logging, and see the raw NETCONF protocol exchange. That should get you all the information that you're looking for.

[Shubham-dash]

@jktjkt actually for verifying purpose that what are the capabilities client and server both exchanging.
