You can connect to your VPS using SSH. It is a network protocol that is applied to have a secure connection between you and a server. It allows you to perform functions like data transfer, remote command execution, command-line login, and authentication. All these and more can be done with data encryption that eliminates the risks of any outside intrusions. 

 

Install PuTTY first and then install a Windows program. Then launch PuTTY and fill in details in the configuration window that opens on your screen. Enter your IP address which you can find in the welcome email r3esolution sent you. Your default port number is 22 and set Connection Type to SSH. Create a file name and save to save all the configurations done so far.

 

The configuration window is replaced by a black terminal window with a "Security Alert". This is to only reconfirm that it is not a fraudster trying to access your account. The entire process is as follows:

 

1. PuTTY connects to OpenSSH 

 

2. OpenSSH attests itself to the PuTTY by sending a Host Key. 

 

3. PuTTY searches for the authenticity of the Host key. 

 

4. If everything is okay, and recheck if you entered the IP address correctly, click yes. PuTTY saves your Host key in its host database in the Windows registry. 

 

5. This completes the server authentication. 

 

Now you must send your login details via the SSH encrypted connection. User your username and then type the password.  When you type the password, the cursor will not move, however, every key is recorded and sent to the server. All the Linux distros run this way. Once done, the client authentication process is over. The command line or Prompt line indicatesusername@hostname:~#.  The command line may differ with each Linux distribution.
