Description Jessica 2013-05-24 19:46:12 UTC 
While testing remote tools changes, I've run into the following situation:

The connection progress just hang in eclipse then I got the error msg the connection failed with no further detailed information.  When I switch to command line to do ssh root@192.168.7.2, I got the following message.  We have fixed the problem for adding entry to known hosts, we need to support this scenario as well.

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
f1:56:c5:47:15:cc:61:97:1f:8c:3c:a2:dd:98:05:90.
Please contact your system administrator.
Add correct host key in /home/jzhang/.ssh/known_hosts to get rid of this message.
Offending RSA key in /home/jzhang/.ssh/known_hosts:18
  remove with: ssh-keygen -f "/home/jzhang/.ssh/known_hosts" -R 192.168.7.2
ECDSA host key for 192.168.7.2 has changed and you have requested strict checking.
Host key verification failed.

Hi Jessica,

The fix that treated know hosts issue, also includs a fix for this case. 
I cannot reproduce this issue.
