Got a warning message while using PuTTY

Asked By 0 points N/A Posted on -


Every time I use PuTTY in Windows, I get this warning message (see below).  I get connected to the server so it seems everything’s okay.  How do I get rid of this warning message from showing up? Any work around or actual solution?  Please help.

PuTTY Security Alert

The server’s host key is not cached in the registry. You have no guarantee that the server is the computer you think it is.

The server’s rsa2 key fingerprint is:

Ssh-rsa 2048 b3:3b:5a:3c:de:a8:c6:49:f0:70:76:bf;47:8d:ac:3e

If you trust this host, hit Yes to add the key to PuTTY’s cache and carry on connecting.

If you want to carry on connecting just once, without adding the key to the cache, hit No.

If you do not trust this host, hit Cancel to abandon the connection.

There are two ways to log in to the server. By log in we mean that the identification process provided to the server.

1-      Provide your user name and password

2-      Public Key Authentication

The second method is more secure and more flexible, and little bit difficult initially to setup.

When the Putty was installed on your system, the administrator has already configured the required keys by using a tool called, PuTTYgen.

These keys have also been loaded as per requirement.

So in order to tackle the security alert ypou are receiving, is that you press “YES”, and the keys will be transferred to the respective caches, and you will NOT be receiving this alert again.

Furthermore, you will be able to directly log on to the server
