SSH authentication


Hi frenz,

I m using SSH client to get connected to other PC. When I tried to connect it very first time, it asked me that it should enter this PC into an authentication list permenently or not. So I give "yes"
After that, that PC got some error and Linux was re-installed. Now it has same IP address as it had before. But when I m trying to do SSH, it gives an error that host has sent "ee:23:df:...." this authentication key and it is not matching. And thus it is not allowing me to do ssh..
So, what should I do now? Do i have to edit any file related to authentication?
Plz help me...

There will be file in </home-directory/.ssh/known_hosts>

edit this file to remove the entry for that machine,on which Linux was re-installed

This security check is to revent MTM attacks.In your case you have reinstalled Linux so no problem,you can go ahead and remove the key for that machine from the file I mentioned above

regards
