Disable getting all schemas

[Zephyre777]

Hello,

I have implemented a client to connect to a router.

I wish to send just one rpc and get a reply after connection setup. But it turned out that at nc_connect_ssh(), it is trying to get all schemas that are supported by the router to fill in context. This process takes at least 3 min for a real router, which is a long time.

What's worse, it sent a close-session request for some strange reason. I am not sure if it has finished with getting all schemas at this point. But then nc_connect_ssh() returns and said cannot connect to server. So the client never send my rpc.

The following is the debug message at the end.

libyang[0]: List's key cannot be of "empty" type until it is in YANG 1.1 module. (path: Path "/ietf-snmp:{augment='/snmp:snmp'}/vacm/group/access/context".)

Session 6555 [DBG]: Sending message:

##

Couldn't connect to the server

I would like to know if there is a way to disable this get-all-schema at the connection setup phase?

Best regards, Zhuoyao

No, there is no way to disable getting all the schemas some way because without them the client is unable to work with the data of the server. If you have lots of YANG modules, it may take a long time for them to get downloaded but after that they are also stored locally so the next connection should take much less time in the setup.

Seems the server sent you some invalid module which is why the client disconnected.
