However, if you cannot use the authenticator app, an alternative, more complex way of achieving the same result with use of MFT will be shown as well. It is recommended that before you start with this tutorial, you already have Google Authentication set up, as shown on the act-ssh landing page, because we will use this method to authenticate to act-ssh when copying the public key. In this step by step tutorial we will set up ssh key authentication to act-ssh – we will create an ssh key pair on the home machine and than we will copy the public key to the UoR systems. With these two pieces of information, you can choose one of several methods to edit the known_hosts file and get connected with our systems again.Act-ssh with MobaXterm – step by step guide Offending RSA key in /Users/me/.ssh/ known_hosts:10 These two lines give us the relevant information. In the example above, the message indicates that there is an entry for the server located on line 10 of the known_hosts file that needs to be removed. If you are unable to get past this error message, you will need to remove the old host key entry inside the known_hosts file. RSA host key for has changed and you have requested strict checking. Offending RSA key in /Users/me/.ssh/known_hosts:10 Please contact your system administrator.Īdd correct host key in /Users/me/.ssh/known_hosts to get rid of this message.

The fingerprint for the RSA 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)! WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

The CAT periodically updates the SSH host keys on its servers for security purposes, which can result in users seeing an error message similar to below when attempting to connect with an MCECS Linux system.
