[SOLVED] How to get rid of "REMOTE HOST IDENTIFICATION HAS CHANGED" message

Issue

I have several virtual machines installed on my computer, to which I connect via ssh:

ssh vm1@localhost

or

ssh vm2@localhost

So every time I connect to different vm I need to edit my ~/.ssh/known_hosts file in order to get rid of: “WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!” message.

Is there any way to trust automatically all VMs on localhost?

Solution

In your configuration (e.g. ~/.ssh/config) you can trash the known hosts for a specific hostname:

Host localhost
        HostName localhost
        UserKnownHostsFile=/dev/null
        StrictHostKeyChecking=no
