[hibernate-dev] Ansible set-up, error "unknown key type ecdsa"

Sanne, When running Ansible to update the CI slaves on OS X, I get the following error: TASK: [jenkins-slave | Ensure cimaster is a known host] *********************** unknown key type ecdsa fatal: [209.132.178.232] => lookup_plugin.pipe(ssh-keyscan -t ecdsa 54.174.65.136) returned 255 Can we use another key type than "ecdsa"? Apparently the SSH coming with OS X has no support for it (see [1]) and I'd prefer to use the default version rather than having to install another one. Thanks, --Gunnar [1] http://apple.stackexchange.com/questions/77731/ecdsa-ssh-key-on-10-8-2
