I’m not able to SSH access with an error showing “Host
Identification Has Changed”, what can I do?
If you see an error message similar to below as shown in Figure 58:
Figure 62 Host ID change warning
It indicates you’ve used a different LinkIt Smart 7688 board or upgraded a new firmware and tried
to access system console using SSH. The new firmware or different board creates a new host
identification which is different from the previous one, hence the error. To fix this issue, you need
to remove the old host ID. Here’s how:
1)
In your Terminal, open the known hosts file. This example uses vi editor, but you can use
any editor you prefer.
$
is the terminal command prompt and is not part of the command.
$ vi ~/.ssh/known_hosts
2)
Find the line or move the cursor to where
myLinkIt.local
is located, as shown below in
Figure 63 Known hosts file
3)
Type
dd
(vi) to delete this entry.
4)
Save and exit the editor by typing
:wq!
(vi)
5)
Now try ssh
again and you should be able to access system console.
