06 Accessing a Linux dedicated server

Connecting to a Linux dedicated server from a Windows computer

• Launch the PuTTY client;
  
  
• in the Host Name (or IP address) field, enter the IP address of the dedicated server;
  • leave the Port field and the Connection Type option unchanged;
• click Open;
• on the next screen, accept the key fingerprint by clicking Yes. This saves the connection key between the dedicated server and the computer you are using, so you will not need to save it again for subsequent access;
• if you click No, you will see the following message every time you access the dedicated server;
  
  
• in the prompt that appears, enter the dedicated server credentials (in the format admin123456 and the corresponding password);
• depending on the operating system installed on the Linux dedicated server, proceed as described below:
