When working with a remote access PuTTY client in Windows, an error may occur due to incompatibility of key formats:
Unable to use key file (OpenSSH SSH-2 private key (old PEM format))
To eliminate this error, the key must be converted by the PuTTYgen tool. Download the utility through the website, open it, and select the "Conversions" tab in the top panel. In the menu that opens, press "Import key" and select the key.
To convert Keys after import, click "Save private key." The key will be saved in a new format (.ppk) with the selected name. If necessary, you can also set the password for the key.
Every dedicated server you ordered includes unlimited KVM access (KVM stands for Keyboard, Video, and Mouse, also it can be named KVM over IP — a virtual remote console for your server). Using this you can work with BIOS and OS directly without our tech support.
For all standard dedicated server plans KVM Virtual Media feature is available. It allows you to upload to the server any files — it’s usually used for ISO images for OS installation. You can then mount it via virtual DVD-ROM.
You can also power cycle your server via KVM web-interface, IPMIview app, or My account.
You can always add authorized users to Your account. Those users would be able to manage services and payments as well as send support requests via tickets and webchat.
To add a new user just click on the
Add user button at the top right of the users’ list.
You’ll need to fill out the following mandatory fields: login and password, email or phone number, name, and last name. As an option, you can add more information.
Please note, that when the new user addition form is opened, some fields may be already filled out. It depends on your browser’s autofill settings, for example, login and password may be filled out with your ones. It makes sense to verify and update it as needed before submitting the form.
Click on the
Add user button at the bottom, and the new user should appear in the authorized users’ list.
To delete a user, please click on
del button in the corresponding row in the users’ list.
You can manage access to your server’s IPMI from the Internet in your Account at Host-telecom.com. Access restriction is implemented due to security reasons.
Here’s what you can do:
- Completely block access to the IPMI address
- Allow access from specific IP(s) and set the expiration time.
- Allow access from specific IP(s) permanently (no expiration date)
- Add both temporary and permanent access rules
- Allow unrestricted access (we strictly do not recommend this option due to security reasons!)
Once you logged in your Account you can use
"IPMI management" menu (picture 1).
You get a list of all your servers equipped with IPMI controller and can select a checkbox for the server you want to change access to. To open the access configuration please click on
"Open/prolong access" button (picture 2).
Please note that servers without IPMI controller are not displayed on this page.
You can choose between the temporary, permanent or unlimited type of access (1) to be open and also input the IP address (2). The system automatically fills out your current IP for your convenience. You can manually set any other IP though (picture 3).
You can add multiple IPs - one in a row, or add (/24) subnet if you provide 3 out of 4 octets (for instance,
After you click on the
"Run" button, all changes take place after 1 minute.
Set the period of time (3) for the temporary access (by default it’s 30 minutes, the maximum is 24 hours).
Please note that for your convenience you can create lists of IP address and then use it for providing/revoking access in bulk (4).
You can also update the list of IPs and extend access time if it’s already configured for some server. ‘New’ time is added to the remainder and applied to the whole IP address list.
Be careful! Technically you can allow unrestricted access to your server’s IPMI, but we strongly recommend not to do that because of security reasons. In this case, your IPMI address is accessible from any IP on the Internet.
You can combine temporary (if it’s required occasionally) and permanent (for IPs that you constantly use to operate the server) types of access for a server.
If you configure both temporary and permanent access to your server from the same IP, it’s granted with permanent access.
To revoke any type of access, please select server(s) and click on
"Close access" button. Changes take place after 1 minute (picture 4).
You can use SuperMicro IPMIView app to work with IPMI KVM-console. It has a richer feature set compared to web-interface. It’s available for Linux and Windows and as a cross-platform Java app.
The tool is available on the official SuperMicro website (sign in required) or FTP: ftp:// ftp.supermicro.com/utility/IPMIView/
You need Java support on your machine to use KVM console, no matter what you use - web-interface or IPMIView.
You can face the following issues if IPMI web-interface of your servers freezes:
- Virtual Media ISO files mounting works incorrectly
- IPMI web-interface does not work or works incorrectly
- Java applet does not start or starts incorrectly
- Java-applet doest not connect to console or connects incorrectly
You can reset IPMI using your account’s dashboard or IPMIView app
Use the following steps to reset IPMI from your account’s dashboard:
- log in to your account
- Go to
Servers and equipmentmenu (on the left)
IPMI cold resettask and run it
UI may slightly differ in different versions
Run IPMIView app and then choose
IPMI device tab at the bottom.
On the screen you'll see
Cold Reset button. If you push it, the IPMI controller will be reset (your server will be not).
IPMI (Intelligent Platform Management Interface) is the controller that is built into all the servers that we offer for rent.
It enables power management, remote connection (KVM), ISO mounting, server health monitoring - everything is remote and no direct access is required.
Once we prepare and issue a server for you, you’ll be able to configure it and set up the operating system.
IPMI operates independently from OS and benefits from a dedicated wired connection and IP address. Thanks to that, even if your OS is not accessible, you can still control your server remotely.
Remote access to IPMI is restricted by default due to security reasons. In order to access it, you need to whitelist your IP(s) in the Account settings. You can find more details in the following guide…
Connection to the IPMI server is implemented with the help of the web-interface or IPMIView Program. We will tell you how to install the operating system using both options and you will be able to choose the one that is convenient for you. We recommend the IPMIView program.
IPMI controller IP address, as well as access credentials, can be found in your Account or in the email, addressing initial server’s provisioning.
Just copy & paste the IP address into your browser’s address bar and use the credentials to authenticate when prompted.
In the top menu, go to
Remote Control, then choose
Console Redirection and then press the
Launch Console button.
After that, you’d need to download and then run Java app. Depending on your operating system configuration, it may require security exception approval.
The window will appear, in which you will need to choose
Virtual Media and then
Device 1 tab choose the
ISO file in the
Logical Drive type drop-down list and path to your ISO image file (use
Open image button).
Once it’s done, press
Plug In button to
plug your image.
After that, you need to restart your server to boot from the ISO file you mounted. Go to
Power control section and click on
Set Power Reset.
Keep in mind that you can connect up to (3) images simultaneously using tabs
Device 2, and
Device 3 (although it depends on a specific type of server you use).
This section can be useful for the installation of additional drivers.
Macro menu section allows sending
Ctrl-Alt-Del and other special keyboard combinations.
