ssh key auth problem


i have two VM running RHEL 5.3. i want to setup ssh key authentication, for this purpose i have followed but the problem is when i try to access remote system it prompts me to enter Passphrase

Enter passphrase for key '/root/.ssh/id_rsa':
STEPs performed on system1 
 [root@linux .ssh]# ssh-keygen  -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Saving the key failed: /root/.ssh/id_rsa.

[root@linux .ssh]# vi

copied the content of to remote system's .ssh/authorized_keys.

Is something wrong in this ?

Saving the key should not have failed.

I am assuming that you did not use a passphrase when you created your keys ... so if you are getting prompted for a passphrase, then that means the system is using a different key (which is most likely since you got that error).

Not so strange: the certificate apparently was protected by a passphrase. So, your local ssh client asked you to enter the passphrase. When you did so (correctly), it submitted the key to the host and it was accepted. "Working as designed..."
