I am getting below exception when I tried to connect my linux box:
(testuser) testuser- ssh -X [email protected]
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
b7:f9:rb:9s:bb:e3:f1:90:4b:af:88:77:1a:da:cf:1c.
Please contact your system administrator.
Add correct host key in /home/testuser/.ssh/known_hosts to get rid of this message.
Offending key in /home/testuser/.ssh/known_hosts:25
RSA host key for hostname.com has changed and you have requested strict checking.
Host key verification failed.
I was able to connect to the same host earlier but I am getting this error now. Should I change anything in my known_hosts file so that I can connect to the Linux box.
