problem with SSH-KEYGEN with some server
i used the method to generate PKI keys using the description from tennis.ecs.umass.edu/~czou/linux/backupSSH.html.
The command to create public key and private key is basically ssh-keygen -t rsa. After that I then copy the public key to the server that I want to connect to. The purpose of me doing this is that I want to connect to server directly therefore without entering any password. Actually, i managed to connect to the server directly for one server without entering the passwd by using this method. But when i tried the same method with another server I had to key in my passwd. I was just wondering, are there any settings in the server which may have caused this method not to work? Any help will be appreciated.thx
