I've been following the instructions here: <a href="https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Identity_Management_Guide/host-keys.html#installing-host-keys">https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Identity_Management_Guide/host-keys.html#installing-host-keys</a> and here: <a href="https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/openssh-sssd.html">https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/openssh-sssd.html</a> I have my host's public key set, it shows up in the web UI, and I have these lines added to the end of the /etc/ssh/ssh_config file on the client machine (that is also a member of the IdM domain): ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p -d LINUXTEST.LIBERTY.EDU %h UserKnownHostsFile2 .ssh/sss_known_hosts I have reloaded the SSH service on the client. I go to connect from my client to my linuxtest server (which happens to be my IdM server), and I get this: [<a href="mailto:karmstrong@linuxclient">karmstrong@linuxclient</a> ~]$ ssh <a href="mailto:karmstrong@linuxtest.liberty.edu"> karmstrong@linuxtest.liberty.edu</a> The authenticity of host 'linuxtest.liberty.edu (<no hostip for proxy command>)' can't be established. RSA key fingerprint is ad:22:28:8d:91:81:3c:07:47:9d:5a:0d:09:33:18:e1. Are you sure you want to continue connecting (yes/no)? no Host key verification failed. The public key fingerprint matches what is set on the host's page in the IdM interface. I do not have a known_hosts in the karmstrong .ssh directory. I have also tried adding the FQDN, and FQDN,ip address into the SSH key on the IdM server through the Web UI, but I still get the bit about not finding an IP for the proxy command to use when it tries to authenticate the host. I have also verified that there is a PTR record in DNS for the host itself, so I believe that it is not a name resolution error. Am I missing something? -Kenny </body> </html>
