[ovirt-users] oVirt SSH rate limit and disable SSH passwd auth

Hello, 1. Is it possible to disable ssh root password authentication in a working oVirt cluster without any problems? (host and ovirt-engine) /etc/ssh/sshd_config PasswordAuthentication no The SSH public authentication key is set on the host. 2. I tried setting ssh rate limit using firewall-cmd but it doesn't work for some reason. I can log in more than once. firewall-cmd --permanent --add-rich-rule='rule family="ipv4" priority="-1" service name=ssh limit value=3/m accept' There is best practice for this? Thanks Peter
