i have two VM running RHEL 5.3. i want to setup ssh key authentication, for this purpose i have followed http://www.petefreitag.com/item/532.cfm
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 id_rsa.pub
copied the content of id_rsa.pub to remote system's .ssh/authorized_keys.
Is something wrong in this ?
