Hi,
it seems there is a problem in libnetconf that is not present in libnetconf2. That is quite expected and the solution is obvious, use libnetconf2. I am sorry, but our support of libnetconf has ended years ago.

Regards,
Michal

Hi Team,

I am using callhome netconf-server(netopeer ) , and want to use ubuntu as callhome netconf-client. Is there any application for callhome netconf-client on ubuntu/linux.

Any help is much appreciated.
Thanks.

Please do not ask duplicate questions and do not reply in irrelevant issues, you should have created a new one. But to answer, you can use our netopeer-cli, or any other NETCONF client (that supports Call Home), there should be more around.
