Introduction
When we replace the login nodes, the host keys will change, therefore upon next login you will receive a message
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 SHA256:qdZ/jPc7HODpO2BmCtJxO51jFZVt1t6fjjbtiUAZemI. Please contact your system administrator. Add correct host key in /path/to/your/home/.ssh/known_hosts to get rid of this message. Offending RSA key in /path/to/your/home/.ssh/known_hosts:252 RSA host key for euler.ethz.ch has changed and you have requested strict checking. Host key verification failed.
Currently valid keys
The currently valid host keys are:
- ED25519 : MD5:2f:c3:be:36:60:86:28:34:d8:4e:cb:27:66:66:25:a4
- ED25519 : SHA256:cbQ9er7E8tFacneNGj2ze09bQUapCuUni5JMiF+wH0A
- RSA : MD5:ab:4b:dd:24:2a:22:eb:5a:74:2a:72:ed:9c:d1:ad:6f
- RSA : SHA256:qdZ/jPc7HODpO2BmCtJxO51jFZVt1t6fjjbtiUAZemI
How to remove the old key and add the new one
Please remove the old host key with the following command
ssh-keygen -R euler.ethz.ch
