Hi All, Please pardon me if it is the wrong list to ask how-to etc. I am having an issue with the Signed SSH keys. I am being asked for the passphrase for my signed public key, even though I don't have any. I am running CentOS7 with OpenSSH_6.4p1, OpenSSL 1.0.1e-fips 11 Feb 2013. 1) I have ca server with ca user keys (ca-user-key.pub) 2) I created user ssh rsa keys (user-id-org and user-id-org.pub). 3) I signed the "user-id-org.pub" with "ca-user-key.pub" and generated "signed-user-id-org.pub". 4) I copied " ca-user-key.pub" to the destination server (dest1.domain.com) and changed "TrustedUserCAKeys /etc/ssh/ ca-user-key.pub" in /etc/ssh/sshd_config. 5) I am trying to get into "dest1.domain.com" using the " user-id-org " as well as "signed-user-id-org.pub". [ ssh -i user-id-org -i signed- user-id-org.pub user1@ dest1.domain.com ] However, I am being asked for the passphrase for signed-user-id-org.pub which I don't have. Below is the output the I pasted from the terminal. [root@lab-linux1 .ssh]# ssh -i user-id-org -i signed-user-id-org.pub user1@ dest1.domain.com Enter passphrase for key '/root/.ssh/ signed-user-id-org .pub': Enter passphrase for key '/root/.ssh/ signed-user-id-org .pub': Permission denied (publickey,gssapi-keyex,gssapi-with-mic). But, If I change the ssh key names to id_rsa, id_rsa.pub and id_rsa-cert.pub with simple using either " id_rsa " or " id_rsa-cert", I can do SSH with out any issues and without any prompting. I am confused here and I don't understand why I have to use only the id-rsa as opposed to any name that I am pointing using the file path. Failed scenarios: 1. I tried giving the options using -o i.e (ssh -o 'IdentityFile /root/.ssh/id_rsa' -o 'CertificateFile /root/.ssh/signed-cert.pub' root@xxxxxxxxxxxxxxx). · command-line: line 0: Bad configuration option: certificatefile 2. Tried by changing the ~/.ssh/config or /etc/ssh/ssh_config · same problem, it says Bad configuration option: certificatefile 3. Tried renaming the files to test_id_rsa and test_id_rsa.pub and test_id_rsa-cert.pub. · Asking for the passphrase of the signed cert. Successful Scenarios: 1. When I rename all the keys to the default named id_rsa, id_rsa.pub and id_rsa-cert.pub. · No issues, I could ssh into the servers using either private key or signed key. [assuming the file names are being automatically taken from a switch case in the code base.] What Should I do? - Can anyone suggest me how to get around this issue. I want to use my own naming convention and my custom location to the keys? Any help is appreciated and Thanks in advance.
