I posted this to you several days ago.

The file you are seeking is located in the computer you are loging in FROM not 
the server.

Look at my previous message:

Hi All

I just spent half a day trying to fix this problem on the wrong computer. In 
justification of the time I was not using SSH directly but fish which uses 
SSH so I was not getting the error messages. Once I tried it connecting using 
SSH I fixed the problem in 5 minutes

In Linux SSH has a computer verification file for computers that have 
permission to log in at /home/<user>/.ssh/known_hosts:2

Explanation. I trashed the HD in one box [a test box with no data in it]. 
After re installation of HD, & configuration I found that I could SSH from 
the  new system but could not SSH from computers which had previously 
connected to the box with the new HD and system. 

I removed contents of above fine saved and was able to immediately log-in.

Hope this helps.
