RHEL 6 / CentOS 6 / Scientific Linux 6 Neither RHEL, CentOS nor Scientific Linux (RHEL/CentOS/SL 6) does not ship with a version of OpenSSH that is compatible with Moonshot (they ship with a non-Moonshot-enabled v5.3 of OpenSSH). To get Moonshot support for it, you must install a specific Moonshot-enabled version (v5. 9). We have a precompiled version available in our repositories.
