# ovirt-aaa-jdbc-tool -bash: ovirt-aaa-jdbc-tool: command not found I did manage to login to Cockpit using IP address: https://{ip}:9090/={ip}/system/services It had problems with hostname. I'm not sure why. It may be related with hardware firewall configuration and multiple vlans I use. Cockpit works with root and password but only if ip address is given. I did also try using login with @ sight and it didn't help. Command ovirt-aaa-jdbc-tool doesn't work. I also can't install nano, "ovirt-aaa-jdbc-tool", and mc. But internet connection is working and I can resolve DNS addresses. Maybe RHEL type of Linux is not so bad but I'm not familiar with it.
