I have upgrade the libssh version from 0.7.7 to 0.9.5. but the netopeer2-server is output error as below.

currently the libnetconf2 version is v1.1.46, whether the libssh0.9.5 is mismatch with libnetconf2 v1.1.46? because the call-home is normal for libssh0.7.7

I have never seen this error

[ERR]: LN: SSH key exchange error (Could not sign the session id).

so I do not think I can help. But you using libssh 0.7.7 and libnetconf2 1.1.46 tells me you are using an old distribution and an old libnetconf2 version so I guess it is time to update both. I am quite sure it will work then.

thanks for your remind. I will re-compile the libnetconf2&netopeer2 base on the libssh0.9.5
