Post RSA host key for 172.17.5.60 has changed


hi
i installed red hat on one of the system currently and when i tried to ssh on it it gave the following problem

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
bf:4a:dd:58:66:1d:ce:ed:f6:5d:cd:21:0b:d6:43:a3.
Please contact your system administrator.
Add correct host key in /home/student/.ssh/known_hosts to get rid of this message.
Offending key in /home/student/.ssh/known_hosts:5
RSA host key for 172.17.5.60 has changed and you have requested strict checking.
Host key verification failed.
what could be the apparent cause of it and how can i remove the same ny suggestions

did you read the dump, or just write it all off as jibberish?

Greetings
Basically, the SSH erver you contacted either renewed the authenicated/encyption key or reinstalled, which would also renew the key. If you're sure that the server is who/what you're contacted then deleted the known_hosts file and continue.

RSA key

In Linux go under:
$ cd /home/oracle/.ssh/
$ vi known_hosts
Delete the entry for "172.17.5.60" then SAVE and Exit.
