cannot login using SSH

Question

cannot login using SSH

general

I just signed on with Linode, booted up Lucid and downloaded a backup image for practise. Then after logging off, I get the following when I try to login. What do I do now???

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

@ 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

f2:4b:8f:25:53:………………………….

Please contact your system administrator.

Looks like you changed the host key on your Linode when you downloaded the backup. Remove the old key from the computer you are using to access your Linode. It's in ~/.ssh/known_hosts on Linux/Unix/MacOS. On Windows – I don't know where it is.

Edit: Stupidity.

Okay. I was booted into the Finnix profile for whatever, so I just rebooted back into the main profile and then in the terminal, deleted the last line in .ssh/known_hosts. Then I could login with ease.
