Hi Jorge,
When I get these errors I look for this line in the error message:
Offending key in /home/jcastro/.ssh/known_hosts:1
That tells me to delete line ":1" in this file "/home/jcastro/.ssh/known_hosts"
on my host machine. When you rerun your ssh command it will generate a
new ssh key in the known_hosts file for that target.
Best regards,
Matt

Hi Stuart,
When I type
ssh<target_ip> -l root
in my machine this is what I get:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
db:96:32:6c:d1:45:d3:c8:a0:8d:0a:b3:a7:d4:f8:b6.
Please contact your system administrator.
Add correct host key in /home/jcastro/.ssh/known_hosts to get rid of this
message.
Offending key in /home/jcastro/.ssh/known_hosts:1
RSA host key for 192.168.100.85 has changed and you have requested strict
checking.
Host key verification failed.
The dropbear is currently working in the target

What I'm not sure is how to change the host key and how can I find it.
Thanks for nay help.
