12/12   Is it possible to keep the same key each time SSH is changed/
        upgraded?
        \_ They key has never changed.  The problem lies in the
           fact that soda has a really really old key the 2 ssh programs
           treat the keys differently.  Really old version of ssh created
           1023 bit keys instead of 1024 and ssh has continued to lie about
           the keysize.  OpenSSH's sshd, on the other hand tells the truth.
           This confuses your ssh client.  -mikeh
           \_ I think that you can fix this by editing the length field for
              the key in your $HOME/known_hosts file.
