Agent admitted failure to sign using the key
I'm working on centos6.5(32bit) and I have tried to ssh log in without Password Using ssh-keygen & ssh-copy-id? the steps that I have done:
first I created the key:
[root@dd ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
8f:48:0b:04:3a:e1:90:f4:9f:de:2a:33:63:ea:a8:82 [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
|+o. |
|+o.. |
|o. .. |
| . .. . |
| .o. S |
| .o.o o |
|. .o.. . |
|E * . |
|*oo =. |
+-----------------+
then I copy the key to the remote host:
[root@dd ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.1.3
[email protected]'s password: My_Password
Now try logging into the machine, with "ssh '[email protected]'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
then I try to login but it fails (with key):
[root@dd ~]# ssh 192.168.1.3
Agent admitted failure to sign using the key.
[email protected]'s password:
and as a verbose logging:
[root@dd ~]# ssh -v [email protected]
