I have the private and public keys.
I have all sesion sniffed.

I'm afraid that's not enough. SSH implements forward secrecy [1],

- From your wikipedia reference:

"In an authenticated key-agreement protocol that uses public key
cryptography, perfect forward secrecy (or PFS) is the property
that ensures that a session key derived from a set of long-term
public and private keys will not be compromised if one of the
private keys is compromised in the future."

I assume if the attacker has the public and private keys from not just
one, but both ends, that PFS is not an obstacle.
