Creating an SSH key on Linux

First, open the terminal (command line) app, then run the following command to generate a 4096 bit SSH key:

1. Login into your virtual machine via VNC or PuTTY or via SSH.
2. Insert into the command line the following command:
   ssh-keygen -b 4096
   The command will output the following result and prompt you to save the newly created key.
3. In order to view the generated SSH-key, input the following command:
   cat .ssh/id_rsa.pub

PuTTY is a popular SSH client for Windows. You can use it to remotely connect to a Linux server. Its companion software, PuTTYgen, can be used to create SSH keys.
First, download the PuTTYgen software, which we will use to generate the key.
Next, run the software and select RSA as the key type, enter 4096 as the number of bits to generate, and then click the GENERATE button.

Click the Save private key button and select a secure location to keep it. You can name your key whatever you’d like, and the extension .ppk will be automatically added.

Insert your SSH key into VM-manager panel.

At first, please login into your HOSTRY member area. Then access your VM-manager account:

Then go the SSH Keys section. Click on the SSH keys Add icon

Add User to Wheel Group

This group called “Wheel” limits the list of users who can use root

# pw group mod wheel -m user.example

Edit the sudoers file

First, you need to check the sudoers file with visudo extension

# visudo

Look for a wheelset. Remove comment if line is off. When you’re ready to save the file, it should look like this

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

Save and exit vi. ESC type, then : W Q, then ENTER

IMPORTANT! The visudo utility performs a syntax check before making changes to the file. The wrong sudoers file can break your system. Never edit /etc/sudoers directly. For example, if you make a mistake, you will see this when exiting visudo.
