Connect to a dedicated server

Last update: November 12 2024

Connect to a dedicated server

You can connect to a dedicated server to remotely manage it:

• SSH — for servers running the Linux operating system;
• RDP — for Windows servers;
• VNC — for macOS servers;
• via KVM console — for servers with any operating system and for servers of the Chipcore Line value-added IP-KVM connection for 3 hours.

If you order a server without an operating system, you can manually install the OS.

View parameters for connection⁠

Parameters for connecting to a dedicated server can be found in control panels:

• user name (login) and password — in section Servers and hardware → Servers → server page → tab Operating system → fields Login и Password;
• public IP address of the server — in section Servers and hardware → Servers → server page → tab Operating system → field IP.

If you forget your server password, you can reset and restore it.

Connect via SSH⁠

The SSH protocol is used to connect to Linux servers.

To connect to the server, you can enter a username and password or use a pair of SSH keys. We recommend using SSH keys instead of login and password — you can connect using keys only from the computer where the private key is stored.

You can store public SSH keys in the control panel in the SSH key store.

From Linux/macOS

1. Optional: Create an SSH key pair and place the public SSH key on the server.

2. Open the CLI.

3. Connect to the server:

   ssh <username>@<ip_address>

   Specify:

   • <username> — user name (login). You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login;
   • <ip_address> — the public IP address of the server. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field IP.

4. Enter the password. The password can be viewed in control panels under Servers and hardware → Servers → server page → tab Operating system → field Password.

   If the server OS was installed from a Linux image prepared by the Selectel team, the number of authorization attempts is limited. After 10 unsuccessful password attempts from one IP address, that IP address will be blocked for 24 hours. If you have forgotten your server password, you can reset and restore it.

   If you are using SSH keys, you do not need to enter a password.

From Windows

In Windows 10, you can connect to a dedicated server in the same way as in Linux and macOS — via the command line (cmd.exe).

In earlier versions of Windows, use PuTTY.

1. Optional:Create an SSH key pair and place the public key on the server.

2. Set PuTTY and run it.

3. Click on the tab Session.

4. In the field Host Name enter the public IP address of the server.

5. In the field Port Specify the port for SSH connection (by default 22).

6. In the field Connection type select the SSH connection type.

7. If you are using a pair of SSH keys, open the tab SSH — Auth, press Browse and download the private key file.

8. Click Open.

9. Confirm the connection and enter the login and password to log in to the server. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login и Password.

   If the server OS was installed from a Linux image prepared by the Selectel team, the number of authorization attempts is limited. After 10 unsuccessful password attempts from one IP address, that IP address will be blocked for 24 hours. If you have forgotten your server password, you can reset and restore it.

   If you are using an SSH key pair, you do not need to enter a password.

Connect via RDP⁠

The RDP protocol is used to connect to dedicated Windows servers.

From Windows

1. Open the menu Start → Connecting to a remote desktop.
2. In the field Computer enter the public IP address of the server. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field IP.
3. Click Connect.
4. Enter a username. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login.
5. Enter the password. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Password.
6. Click OK.

From Linux

1. Install an RDP client (rdesktop, Remmina, etc.). Read more in Selectel's blog article RDP remote access clients for Linux.

2. Open the CLI.

3. Connect to the server (example for rdesktop):

   rdesktop <ip_address> -u <username> -p <password>

   Specify:

   • <ip_address> — the public IP address of the server. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field IP;
   • <username> — user name (login). You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login;
   • <password> — password. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Password.

From macOS.

1. Set Microsoft Remote Desktop and run it.
2. To create a connection, tap +.
3. In the field PC name enter the public IP address of the server. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field IP.
4. In the field Username enter the user name. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login.
5. In the field Password enter the password. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Password.
6. Click Save.
7. Double-click the created connection in the list.

Connect via VNC⁠

To connect on a local computer, you can use a client for VNC. The standard port for connection is 5900.

The VNC protocol is used for remote access to dedicated Windows, Linux, and macOS servers:

• Use RealVNC Viewer to connect to macOS servers from Windows or Linux;
• Use a suitable client to connect to Windows and Linux servers from different operating systems:

	Installed on Windows	Installed on Linux	Installed on macOS
RealVNC Viewer	✓	✓	✗
TigerVNC	✓	✓	✗
UltraVNC	✓	✗	✗
Remoute Ripple	✓	✓	✗
Remmina	✗	✓	✗
Finder	✗	✗	✓

From macOS.

1. Start the Finder.

2. Open the menu transition → Connecting to the server.

3. In the field Server address enter:

   vnc://<ip_address>

   Specify <ip_address> — the public IP address of the server. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field IP.

4. Click Connect.

5. Enter your user name and password. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login и Password.

   • <port> — port for VNC connection (default is 5900).

4. In the field Username enter a user name. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login.

5. In the field Password enter the password. You can look in control panels under Servers and hardware → Servers → server page → tab Operating system → field Password.

6. Click OK.

Connect via KVM console⁠

Connect via the KVM console to the control panels can be connected to a dedicated server with any operating system.

To connect via KVM console to Chipcore Line servers, order an additional service IP-KVM connection for 3 hours. For more information on working with the KVM console, please refer to the instruction manual Manage the server through a KVM console.

1. В control panels go to Servers and hardware → Servers.
2. Open the tab Server list.
3. In the server card, click . KVM console will start in a new browser tab. If required, Expand the KVM console window.
4. If you have an X8DTU motherboard, synchronize the cursor.
5. If the KVM console asks for permission to start, confirm the permission by pressing Run.
6. If the KVM console prompts for authorization, move the cursor sequentially to the Username и Password and click on username и password in the lower right corner of the window. The values in the fields will be inserted automatically. If you do not see the button in the lower right corner, reconnect to the console.
7. If the KVM console control panel appears in front of you, from the left menu, select the Remote control. On the remote access page, tap Launch H5Viewer.
8. Authorize on the server. View login (username) and password (password) can be in control panels under Servers and hardware → Servers → server page → tab Operating system → field Login и Password. The password is available for review 24 hours from the start of the OS installation or configuration change. If you are connecting to a Windows server, make sure that the English layout is enabled on the server when entering the password.
