Our technicians can attach a remote console to any of your Hetzner dedicated root servers. This remote console provides KVM (keyboard, video and mouse) over-IP functions and enables full BIOS level control of the server. It is useful for troubleshooting a server, especially in cases where you can't use SSH. You can access the boot menu and fix network configuration errors. The console has virtual media support, so you can use it to install a custom operating system by mounting an ISO file.
The name we use for one of our remote consoles is
KVM Console. This term comes from the name of the original remote consoles that we provided several years ago. We have updated the system since then, but we kept the old name.
A KVM Console is free for 3 hours. If you need it for a longer period of time, you can book it for 3 more hours for just € 8.40 (not including VAT).
Important note: Java is required when you use the KVM console features.
Since the number of KVM Consoles in each DC is limited, we recommend that you order the KVM Console in advance.
Please request a KVM Console directly via Robot. To do so, log into Robot, go to
Servers, select your server, and click on the
Support tab. You will see a support form. Here, please select
Remote Console. You can then choose if you want it immediately, or if you want to make an appointment for when you want it. You can also enter how long you want it, and you can write a note to our support team in the 'Comment' area if you want to.
Once our technicians have connected a KVM Console to your server, they will send you an email with the login details, as well as the URL of the KVM Console. You can simply click on this URL, or you can copy and paste it into your browser. You will then see the following screen:
Once you have logged in with the login details from the email, you will see the following screen:
KVM Console Preview (see screenshot above), you can click on the screen itself to open the console, or click on the
Click to open KVM Console link at the bottom.
A dialog box will pop-up asking what you want to do with the file
spider.jnlp. You need to open this with the
JAVA(TM) Web Start Launcher, which should automatically be selected.
- Lantronix support states that the KVM Console will not work fully with Java 9 or 10. To maintain functionality, stay with Java 8.
- If Java 8 is not yet installed on your computer, please visit the Java website and download the latest version and then install it.
- A security warning might pop-up. This is a general warning from Java and doesn't mean there are any security problems with the Java applet. You can accept the warning without worrying about it.
- Unfortunately, some browsers cancel the download of the applet with an error message (file incomplete / invalid certificate). Please use an alternative browser if this happens. With a current standard version of Mozilla Firefox, for example, you shouldn't have this problem.
Once the Java applet has initialized, the console should open, and you will see the screen output of the server as though you were sitting right in front of the server itself.
If the keys you are pressing on your own keyboard are not being accurately shown on the screen/console, then the keyboard layout is most likely incorrectly set. You can change this under the menu tab
Options by going to
Local Keyboard. There, you need to select the correct keyboard layout of the keyboard you are using.
confirm Ctrl+Alt+Delete button at the top left of the console, you can send the server a ctrl+alt+delete. You can use this to restart the server or to log into Windows. Once you have clicked on that button, you will need to confirm that you want to send a ctrl+alt+delete to the server.
You can choose to have the console fill your screen if you want. Simply press Ctrl+F10, or one of the buttons at the top of the console with an A or S and arrows pointing outwards. You can leave full screen mode by pressing Ctrl+F10 again.
Important time-saving note: If you want to install one of the standard Linux operating systems we provide, you can do this yourself and automatically via Robot by going to the
Linux tab of the server. Or you can can install it manually via our installimage or VNC installation.
To access the virtual media interface, please click on the
Interfaces tab, and then go to the
Virtual Media link. Here, you can enter the details of the location of the ISO file.
- The KVM Console only supports the mounting of ISO files via the SAMBA (SMB)/CIFS networking protocol.
- Mounting a file can take a significant amount of time, so please make sure you have a good connection to the location of the file. Unfortunately, there is no progress bar. You will see a notification once the file has been fully loaded.
- We cannot guarantee that mounting an ISO file and installing it will always work. For that reason, we offer the option of having our technicians burn the ISO file onto a USB stick/DVD for you.
To help our clients install Windows, we provide a number of images of Windows operating systems.
You can find the images we provide on two of our mirrors:
- http://download.hetzner.de/ is accessible from anywhere, and requires a username and password to login. You can find these login details at the end of the server activation email. This is the same email that contains the login details for the server itself.
- http://mirror.hetzner.de/ is only accessible from within the Hetzner network, and it does not require a password.
The following examples use the internal mirror, though a link to the external mirror is also mentioned. You can use the link to the external mirror to check the exact file names of the operating system images.
You can find the Windows images we have at http://download.hetzner.de/bootimages/windows/.
These Windows images are straight from Microsoft and don't include any changes from us. They do not come with a license. You can use them to install a clean Windows OS on the server, and you can then activate it with your own license key.
- You can copy the "Image File with Path" name directly from our mirror.
- You can leave the "User Name" and "Password" fields blank; you don't need them.
You can access our backup space via SAMBA/CIFs. That means you can use it to host an image which you can then mount using a KVM Console.
See also: SAMBA/CIFS on our backup space.
<username>is the username of your backup space, which you can find on Robot by clicking on the "Backup" tab of the server.
<file_name>is the file name of the ISO file.
- If you have placed the ISO file in a sub-folder, then please specify that before the file name. For example:
- The password is the one you have set for the backup space.
The ISO file doesn't have to be hosted by us. You can host the ISO file wherever you want, as long as it is reachable via SAMBA/CIFS. This could be from another server at Hetzner, from a third-party server, or even from your own computer/server at your office/home.
Important note: This can take a long time, so please be patient as the image is being mounted/uploaded.
If the options mentioned above for mounting an ISO file don't work or take too long, then there is always the option of asking our technicians to put the image onto a USB stick and attach that to the server along with the KVM Console.
Please send our technicians a link to the ISO file you have. When you order the KVM console, you can include a link to the ISO file in the "Comment" section of the support ticket. Or you can give our support team the link later when by responding to your support request for the KVM Console.
The ISO file does not necessarily have to be reachable via SAMBA/CIFS; it can simply be reachable via ftp for example, since our technicians will be connecting to it directly, and not via the KVM Console.
Once the ISO file has been mounted/attached to the KVM Console, you will need to restart the server and boot from it. You can do this can using the
KVM Console function of the KVM Console.
When booting the server, please enter the boot menu. On most motherboards, you can do this by pressing F11 during boot. Please note that some motherboards require a different function key, like F6, to enter the boot menu, so please keep an eye out for the appropriate prompt.
Once you are in the boot menu, select
PepperC Virtual Disc 1 0.01 if you have mounted the file using the KVM Console. Or, if our technicians have connected a USB stick for you, then select the appropriate option to boot from that.
JetFlashTrascend 16GB 1.00 is an example for a USB stick.
Now you can simply follow the on-screen instructions to install the OS you have mounted/attached to the KVM Console.
Loading the installation files for Windows takes around a minute if you are using a USB, but can take longer, 10-15 minutes, via a mounted ISO file (via our mirror). If you have mounted the ISO file from somewhere else, then it can take even longer.
