Connect to a cloud server

You can connect to a cloud server:

• via SSH — to a server with the Linux operating system;
• via RDP — to a server with the Windows operating system;
• via the console in the control panel — to servers with any operating system.

To be able to connect to a cloud server via SSH or RDP, the server must have internet access:

• via a public IP address and cloud router;
• or via a public subnet.

View connection settings

You can view the settings for connecting to a cloud server in the control panel:

• public IP address — from the top menu, click Products → Cloud Servers → server page → Ports tab → in the port card, click next to the public IP address;
• username (login) and password — from the top menu, click Products → Cloud Servers → server page → Console tab → Login and Password.

If you forgot your server password, you can reset and recover it.

Connect via SSH

The SSH protocol is used to connect to cloud servers running Linux.

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

You can store public SSH keys in the control panel; to do this, add your public SSH keys to your user profile.

From Linux/macOS

1. Optional: create an SSH key pair and place your public SSH key when creating a cloud server or on an existing server.

2. Open the CLI.

3. Connect to the server:

   ssh <username>@<ip_address>

   Specify:

   • <username> — username (login). You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Login field;
   • <ip_address> — public IP address of the server. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Ports tab → in the port card, click next to the public IP address.

4. Enter the password. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Password field.

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

From Windows

On Windows 10, you can connect to a cloud server in the same way as on 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 your public SSH key on the cloud server: when creating the server or on an existing server.

2. Install PuTTY and launch it.

3. Open the Session tab.

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

5. In the Port field, specify the port for the SSH connection (default is 22).

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

7. If you are using an SSH key pair, load the private key file.

   7.1. Open the Connection → SSH → Auth → Credentials tab.

   7.2. In the Private key file for authentication field, click Browse.

   7.3. Load the private key file.

8. Click Open.

9. Confirm the connection and enter the login and password to access the server. You can view the login and password in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Login and Password fields.

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

Error during reconnection

If you use SSH keys to connect, the SSH key is saved to the ~/.ssh/known_hosts file upon your first authorization on the server. If you reconnect, the error REMOTE HOST IDENTIFICATION HAS CHANGED may appear.

To fix the error:

• delete the host information by IP address:

  ssh-keygen -f "/home/root/.ssh/known_hosts" -R "<ip_address>"

• or connect to the server using the command:

  ssh -o UserKnownHostsFile=/dev/null root@<ip_address>

Connect via RDP

The RDP protocol is used to connect to cloud servers running Windows.

From Linux

1. Install an RDP client — for example, rdesktop or Remmina.

2. Open the CLI.

3. Connect to the server using your RDP client. Example command for rdesktop:

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

   Specify:

   • <ip_address> — public IP address of the server. You can copy it in the control panel: from the top menu, click Products → Cloud Servers → server page → Ports tab → in the port card, click next to the public IP address;
   • <username> — username (login). You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Login field;
   • <password> — password. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Password field.

From macOS

1. Install Microsoft Remote Desktop and launch it.

2. To create a connection, click +.

3. In the PC name field, enter the public IP address of the server. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Ports tab → in the port card, click next to the public IP address.

4. In the Username field, enter the username. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Login field.

5. In the Password field, enter the password. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Password field.

6. Click Save.

7. Double-click the created connection in the list.

From Windows

1. Open the Start menu → Remote Desktop Connection.

2. In the Computer field, enter the public IP address of the server. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Ports tab → in the port card, click next to the public IP address.

3. Click Connect.

4. Enter the username. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Login field.

5. Enter the password. You can view it in the control panel: from the top menu, click Products → Cloud Servers → server page → Console → Password field.

6. Click OK.

Connect via the console in the control panel

You can connect to a cloud server with any operating system through the console in the control panel.

The console is a browser-based VNC client; we recommend using it only when it is impossible to connect to the server via SSH or RDP. Copying text from the console is not available; you can paste text using the Ctrl+V shortcut.

1. In the control panel, from the top menu, click Products and select Cloud Servers.

2. In the server row, click .

3. Enter the username (login). You can view it in the Login field.

4. Enter the password. You can view it in the Password field.
