We just recently set up a password-less connection between two servers. P.S.: if any Windows-savvy folks know of a more efficient way to do this, I’m all ears! Hope it still helps you or anyone else out! Just happened to run into your comment while I was looking into this myself and that’s when I connected the dots. I guess rebooting the machine would also work, but that’s a bit of a hassle compared to this method. The command removes/depopulates the variable, if I’m not mistaken (on Linux I would just overwrite the variable to be blank but that doesn’t seem to work for me in Windows), after which you can establish the connection without issues. I reckon this is just a temporary variable you’re populating with the contents of what would normally be written to your known_hosts file. For example, if you wrote “UserKnownHostsFile=NULL”, it would be: If anyone runs else runs into this issue, just use whichever string you pointed UserKnownHostsFile towards. Try using the following command in your command prompt: UserKnownHostsFile=/dev/null Disable SSH host key checking For 192.168.0.0/24 Host 192.168.0.* Disable SSH host key checking for all hosts Host * If you are sure that it is harmless and the remote host key has been changed in a legitimate way, you can skip the host key checking by sending the key to a null known_hosts file: $ ssh -o "UserKnownHostsFile=/dev/null" -o "StrictHostKe圜hecking=no" can also set these options permanently in ~/.ssh/config (for the current user) or in /etc/ssh/ssh_config (for all users).Ĭool Tip: Log in to a remote Linux server without entering password!

If you would like to bypass this verification step, you can set the “ StrictHostKe圜hecking” option to “ no” on the command line: $ ssh -o "StrictHostKe圜hecking=no" option disables the prompt and automatically adds the host key to the ~/.ssh/known_hosts file.
If your answer is ‘no’, the connection will be terminated. If your answer is ‘yes’, the SSH client continues login, and stores the host key locally in the file ~/.ssh/known_hosts. When you log into a remote host that you have never connected before, the remote host key is most likely unknown to your SSH client, and you would be asked to confirm its fingerprint: The authenticity of host ***** can't be established.Īre you sure you want to continue connecting (yes/no)?

By default, the SSH client verifies the identity of the host to which it connects.
