Hi,

Is this what you are saying:

Twisted Server + OpenSSH client == WORKS

Twisted Server + Xshell client == WORKS

OpenSSH Server + SecureCRT client == WORKS

Twisted Server + SecureCRT client == FAIL

I don't have SecureCRT client, so don't know the solution to this problem.

You might want to try searching the SecureCRT site and see if there are any clues

hi:
Oh, I'm sorry, It is my server-side code has bugs with Twisted(16.6.0) Conch, that i have fixed it . But 'Message Authentication Code did not verify (packet #3)' error will occurs with the SecureCRT(8.0.0 or 7.3.4) client. If I connect OpenSSH_5.3p1 (or OpenSSH_6.6.1p1 ) sshd server through the SecureCRT client, it is fine. Of course， if I connect Twisted SSH server by using the Xshell client with hmac-sha2-512 options or “ssh -m hmac-sha2-512”，it is OK. I do not know if it is SecureCRT client bug or twisted problem. http://stackoverflow.com/questions/41296412/securecrt-hmac-sha2-512-message-authentication-code-did-not-verify-packet-3
