Problem in logging in freerunner through ssh

[Marcus Bauer]

Paul Bonser answered already with the fix.

I'll add the reason: whenever you connect to an unknown system, you are
asked if you want to accept the key like this:

-----------------------------------------------------------------
The authenticity of host '192.168.0.202 (192.168.0.202)' can't be
established.
RSA key fingerprint is d8:c1:d2:ac:e9:57:9f:ed:1d:ee:b3:fa:62:04:8c:6c.
Are you sure you want to continue connecting (yes/no)?
-----------------------------------------------------------------

and when you answer 'yes' the public key will be saved to your
~/.ssh/known_hosts file. This prevents the so called
man-in-the-middle-attack. Search google or wikipedia for more details.

If you reflash your phone, the public key changes (it is unique and
generated on the first boot) and your ssh believes there is an attack.
Somewhere on the wiki is a description how to shut this behaviour off,
but I hope nobody will ever inactivate this vigilance.

HTH, best regards,
Marcus
