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 key changed because I reinstalled that machine so there is not really anyone trying nasty things, I just need to get rid of that line (84). In order to open the file in vim at that line I used:
$ vim +84 /home/giallu/.ssh/known_hosts
followed by "dd" (delete line) and ":wq" (save and exit)
That's all for today's vim trick...
