Then you have updated your local key for connecting to the remote server for good. When prompted with something like are you sure you want to add the host key permanently to this machine? type yes. Where /Users/ben/document/key.pem is your server's key pair you had set to use (can't find it anymore? go to the hosting site to regenerate one) and 192.168.0.45 is your remote server IP you are connecting to. Now reconnect to your host via ssh, using something like this: ssh -i /Users/ben/document/key.pem Once deletion is done, save it by command Ctrl+ o and quit the file by command Ctrl+ x. No easier way just use your keyboard cursor and backspace or delete keys. You would want to deleted the line mentioned ONLY. The simplest solution would be just deleted the line mentioned (line 74) in your local pc in /var/root/.ssh/known_hosts by sudo nano /var/root/.ssh/known_hosts For security reasons the connection is not established. It says that the remote server host key has changed - therefore your previously stored local record DOES NOT MATCH any more. For instance in the earlier answer: my_mac:~ oivanche$ sudo ssh WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Remove the line from the known_hosts, save changes and reconnect.įor most of the cases, the error msg returned by the Linux would have told you what to do. If you'll read the log more carefully you'll see that the key you've got from a host is conflicting with a key you already have - in this case it's on line 74 of known_hosts file (Offending ECDSA key in /var/root/.ssh/known_hosts:74). Now any time you want to connect to your remote postgres server, simply start an ssh tunnel. Remember, port 2222 is the local port we defined that will pop out on the remote server as port 5432. Offending ECDSA key in /var/root/.ssh/known_hosts:74ĮCDSA host key for 192.168.0.45 has changed and you have requested strict checking. On the client machine (the one you made the ssh tunnel from), open a new terminal and run the following command: psql -h localhost -p 2222 -U postgres. Please contact your system administrator.Īdd correct host key in /var/root/.ssh/known_hosts to get rid of this message. SHA256:sx1Z4xyGY9venBP6dIHAoBj0VhDOo7TUVCE2xWXpzQk. The fingerprint for the ECDSA key sent by the remote host is It is also possible that a host key has just been changed. Someone could be eavesdropping on you right now (man-in-the-middle attack)! I don't know about your particular situation, but most probably this error came along with a message like this: my_mac:~ oivanche$ sudo ssh WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! # df.to_excel('result/data.Just do "sudo vi /var/root/.ssh/known_hosts" and remove the line, that holds a key for a host you're trying to connect to and reconnect again. read_sql ( 'SELECT * FROM fuga', con ) # CSV 保存ĭf.
