SSH MITM

[KST]

Hi

I test the ssh mitm by the way this link.

I have three PC ;attacker PC,ssh server and ssh client.After all instruction are made, I connect ssh to server from client .But when I do this , I cannot login with user from server. I can only login with attacker 's username and password and get logined to attacker pc.It means that attacker pc doesnot redirect to ssh server. But I have completed all instructions described in that link.

If you have time, please check my question and answer me.
