WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
After doing ssh are you seeing this error.No problem it can be solved.
[email protected]:/tmp# ssh 10.10.0.16 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 RSA key sent by the remote host is 13:f2:a2:87:ff:79:e5:92:79:b4:10:51:53:c2:fb:60. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /root/.ssh/known_hosts:11 remove with: ssh-keygen -f "/root/.ssh/known_hosts" -R 10.10.0.16 RSA host key for 10.10.0.16 has changed and you have requested strict checking. Host key verification failed. [email protected]:/tmp#
Why it happens ?
Answer : Because it is mismatch of fingerprint information which is saved in .known_hosts file in your system with fingerprint value available in Server.
How to solve the issue
You have to delete the particular line from ~/.ssh/known_hosts file.
see the line no. 12 in above message “Offending ECDSA key in /root/.ssh/known_hosts:11“.
In line you are getting number 11 . Hence this is the line no. in known_hosts which you have to delete.
Here we will use vi editor to directly jump into that line number
vi +11 ~/.ssh/known_hostsCursor will automatically move to line number you only have to type dd in vi editor to delete the line and then type :wq for save and exit
dd
:wq当然，这里可以把指定ip的message删除掉。再次执行scp，系统会生成最新可用的message。
