Can't connect to my aTV jailbroken

Hi,

I jailbreak my aTV 2 v5.0 and install aTV Black. I wanted to connect into SSH to install app for my keyboard + mouse in bluetooth,

but I had this message:

 

Tamatoa$ ssh root@192.168.1.68

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Someone could be eavesdropping on you right now (man-in-the-middle attack)!

It is also possible that the RSA host key has just been changed.

The fingerprint for the RSA key sent by the remote host is

cc:98:89:f3:66:2b:62:c7:77:b7:1f:02:f7:9e:06:ac.

Please contact your system administrator.

Add correct host key in /Users/Tamatoa/.ssh/known_hosts to get rid of this message.

Offending key in /Users/Tamatoa/.ssh/known_hosts:1

RSA host key for 192.168.1.68 has changed and you have requested strict checking.

Host key verification failed.

 

I don’t know what to do now!
Need some help :D
