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
36:85:1f:c0:7c:b6:d3:65:3c:2c:06:7a:20:25:c7:1d.
Please contact your system administrator.
Add correct host key in /home/bijendra/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/bijendra/.ssh/known_hosts:23
  remove with: ssh-keygen -f "/home/bijendra/.ssh/known_hosts" -R ec2-46-137-194-78.ap-southeast-1.compute.amazonaws.com
ECDSA host key for ec2-46-137-194-78.ap-southeast-1.compute.amazonaws.com has changed and you have requested strict checking.
Host key verification failed.

In case you see these messages while you ssh into the server, the identity of that instance has changed. Clear your home_folder/.ssh/known_hosts with the entry of the instance and now ssh. Accept the new identification. Known_hosts is a file which keeps track of the remote servers which you access and enters automatically for the next time.
