IT is POSSIBLE this SOMEONE is DOING SOMETHING nasty!
Someone could is eavesdropping on your right now (Man-in-the-middle attack)!
It is also possible, the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
F5:0a:e2:80:47:e4:c8:9b:b9:96:19:e4:a4:0f:de:b3.
Please contact your system administrator.

RSA host key for 192.168.1.57 had changed and you have requested strict checking.
Host Key verification failed.
Rsync:connection unexpectedly closed (0 bytes received so far) [sender]
Rsync error:unexplained Error (code 255) at IO.C (+) [sender=3.0.6]

The reason is that the system has changed, causing the encryption key to change, so the local saved key fails;
the key needs to be re-saved in ~/.ssh/known_hosts.
Workaround:
Delete the key for the specified IP in the ~/.ssh/known_hosts file.
