Hi,
I have deployed AES-GCM as cipher in my server and the kex method are ecdh-sha2-nistp521 signing: ecdsa-sha2-nistp521 cipher suite: aes128-gcm@openssh.com When I try to use dbclient to talk to my server I have encountered Received out-of-order kexdhreply error It works fine while using OpenSSH to talk to the server. I did a deep investigations. It seems like from the OpenSSH the client side should follow this process: SSH_MSG_KEXINIT SSH_MSG_KEX_ECDH SSH_MSG_NEWKEYS SSH_MSG_SERVICE_ACCEPT Somehow while using dbclient It switches back to SSH_MSG_KEXINIT after SSH_MSG_NEWKEYS so it never reaches SSH_MSG_SERVICE_ACCEPT I have attached log below. Any helps will be super grateful |
