Is there a way to stop SSH from asking for a fingerprint?
This setting will make sure that ssh will never ask for fingerprint check again. This should be added very carefully as this would be really dangerous and allow to access all fingerprints. Thanks for contributing an answer to Stack Overflow!
Can a remote host change the host fingerprint?
Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is
What happens if I accept a new SSH key?
When you do not check the host key you might land with an SSH session on a different computer (yes, this is possible with IP Hijacking ). A hostile server, which you don’t own can be then used to steal a password and all sort of data. Accepting a new unknown key is also pretty dangerous.
How can I force SSH to accept a new host?
You should never turn off StrictHostKeyChecking in any real-world system (e.g. it’s probably okay if you’re just playing on your own local home network – but for anything else don’t do it). That will force the known_hosts file to be updated to remove the old key for just the one server that has updated its key.
What to do if your SSH host key has changed?
It is also possible that a host key has just been changed. The fingerprint for the RSA key sent by the remote host is 6e:45:f9:a8:af:38:3d:a1:a5:c7:76:1d:02:f8:77:00. Please contact your system administrator. Add correct host key in /home/hostname /.ssh/known_hosts to get rid of this message.
Why did my SSH host IP change to 212.156.48.110?
To resolve this issue, you have to remove previously stored RSA key for the ip 192.152.51.10. Deletes only the target ssh host IP from know hosts. where 212.156.48.110 is replaced by the target host IP address. Cause: Happened because the target IP was already known for a different machine due to port forwarding.
