Since June 2007 Hetzner Online offers VNC installations through the Robot.
VNC is software that shows the screen output of a remote computer (running the VNC server software) on a local computer (running the VNC viewer software), and it can send keyboard and mouse movements that are made on the local computer to the remote computer. Thus, the remote computer can be installed as though you are sitting directly in front of the remote computer and monitor.
During this process, all data is copied over the network. Since the needed data is located on Hetzner's download servers, the installation of the packets should not take longer then when installing from a CD or DVD.
However, you need a VNC client (http://en.wikipedia.org/wiki/Virtual_Network_Computing) to access the installation routine.
To start a VNC installation, click on the VNC tab of your server in Robot. Here you will see a dropdown list of available operating systems, as well as the architecture and the language. After selecting the configuration you want, and pressing the activate button, a password will be displayed with which you can login to the VNC installation, a few minutes after you restart the server. VNC address would be:
- CentOS 6.10
- CentOS 7.7
- CentOS 8.1
- Fedora 31
- openSUSE 15.1
The VNC installation of openSuSE is done in two steps. First, the languages, the time, the partitions, the packages, etc. are selected and the boot loader is installed. After installation, the system will reboot and automatically setup a VNC connection again. You can login (again) with the previously used password. In this second step, the installation is completed, which usually requires only minimal user interaction. The system then reboots normally and is accessible via SSH.
UltraVNC are used as VNC clients, then under certain circumstances disconnections can happen. In these cases try the following configurations:
- Hextile Encoding
- Color Level Low (256 colors)
During the installation a firewall is activated automatically. By default, only a small handful of ports are approved - including SSH. Instead of iptables firewalld is now the default firewall. Settings on the firewall can be changed using the following program:
Fedora 25 can not be installed on the Virtual server CX10 since more than 1GB RAM is required for the installation.
