In new server today created a authorized_keys file in /root/.ssh/ directory. After doing ssh first time got the error – Agent admitted failure to sign using the key
For solving this issue use the command ssh-add in client machine
Given below are the outputs from terminal. The solution pretty much straight simple.
sharad@mypc:~$ ssh email@example.com Agent admitted failure to sign using the key. firstname.lastname@example.org's password: sharad@mypc:~$ ssh-add Identity added: /home/sharad/.ssh/id_rsa (/home/sharad/.ssh/id_rsa) sharad@sharad-sapplica:~$ ssh email@example.com Last login: Tue May 28 08:52:15 2013 from 192.168.156.23 [root@server1 ~]#
