How Do I fix this problem with terminal. I am a complete NOOB and have no idea how to set up commands properly. I was trying to jailbreak my device and add cydia to it on 8.1 but i ran into an issue with terminal while performing an "ssh"

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

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 a host key has just been changed.

Add correct host key in /Users/JO3/.ssh/known_hosts to get rid of this message.

how exactly do I fix this?

"Host key verification failed" means that the host key of the remote host was changed.

Ssh stores the host keys of the remote hosts in ~/.ssh/known_hosts. You can either edit that text file manually and remove the old key (you can see the line number in the error message), or use

ssh-keygen -R hostname

If you do not want to manually mess with the lines use this command and it should fix the issue...

To correct it, simply go to your Terminaland type in the following command,

sed -i '1d' ~/.ssh/known_hosts

I’m using ‘1’ because the error from above says that my offending line is line 1):

known_hosts:1

Also, I am assuming you have administrator access as you will need the same...
Hope this helps...
