Upgraded to Merlin 386.1 but got "warning: remote host identification has changed" when trying to SSH into the router

I realize that I have to delete the offending key, I've tried to do that with the "ssh-keygen -R [192.168.X.X]port#," but my mac just states that the hostname is not found. Any thoughts?

I got that too. Was coming from 384.19 and have seen that before with other FW updates.

Is it not prompting you to accept the new key?

Yes. I tried using ssh-keygen, but it didn't recognize, so I had to go into vim and delete the offending line. This is completely new to me so I had to do some searching on YT and Google, but it now works.

On a Mac you could also use Go to Folder in the Finder to delete the known_hosts file you'll find there.

Go to:

/Users/Username/.ssh/

I can confirm that. Happened while logging in with PuTTY and WinSCP too. It's not unusual after updating fw imho.

Go to:

/Users/Username/.ssh/

It is the same with Windows. Either delete known_hosts or edit the file and remove the router IP line (if like me and you 5 or so other machines I ssh into).

I don't want to delete the entire key file on my Mac so I edit it:

sudo nano /Users/YourUserName/.ssh/known_hosts
Move to line of device you want to delete and type Ctrl-k
Type Ctrl-x
Type y

Now next time you log in it will prompt you to add your new key.

On the Mac it should also be possible to run ssh-keygen -R to remove the router entry:

-R hostname | [hostname]ort
Removes all keys belonging to the specified hostname (with optional port number) from a known_hosts
file. This option is useful to delete hashed hosts (see the -H option above).

Yes, that was the first action I undertook, but unfortunately, it didn't work for some reason. I had to manually delete the offending line.
