We recommend several steps before you install any software layer onto the new environment.
This is an important security step if you are intending on using your server for production projects.
1. Get server IP and root password
After successful payment is approved, your server will be set up within 2 minutes.
A. Login to the Hosting Portal
Bookmark login: https://console.hostjane.com/client/login
In your Dashboard under Services, find your Ubuntu server.
|Package||Label||Term||Date Created||Date Renews||Options|
|Ubuntu||host.domain.com||1 month @ $0.00||Jan 1||Feb 1||Manage|
We offer 24×7×365 support
If you cannot see your Ubuntu service, open a support case.
B. Click the Manage option
This is the button in the last column under Services.
Here is the next screen that will display:
|Creation Date||Next Invoice|
|Jan 1||Feb 1|
|Billing Cycle||Recurring Amount|
C. Click Statistics in the side menu
The Main IP is your virtual machine’s IP address.
The Default Password is the root password.
For security, HostJane does not send this to you by email.
You must login to your hosting account to review these credentials.
2. Login with SSH
Login to your server with PuTTY on Windows or an OpenSSH client in linux and MacOS devices:
ssh -l root [Your_Server's_IP]
Your_Server’s_IP with the server IP address given in Statistics.
3. Create a new user
For security reasons it’s best not to use the root user for everyday administrative tasks.
The solution is to create a new user.
Enter the following:
Replace janedoe with the unique name of your new user.
You will be automatically asked to set a new password for janedoe, and to reenter the password to confirm.
Press Enter to proceed with default information, otherwise enter values for your:
- Full name
- Room number
- Work phone
- Home phone
4. Install sudo on Ubuntu
Add janedoe to the sudo group to assign super-user privileges to the user.
usermod -aG sudo janedoe
Your new user can now have root privileges using
5. Set up public SSH keys
We recommend you set up an SSH key pair to secure your server.
SSH key setup is easy and free, but if you’re not comfortable doing this we recommend hiring a system administrator on HostJane Marketplace.
After you’ve set up your SSH keys, open another terminal on your local machine.
Add your SSH key to janedoe‘s home directory via the new terminal.
With the SSH key now installed, log back into your cloud server using your new janedoe user.
ssh -1 janedoe Your_Server's_IP
Login should be successful.
Close all other open terminals.
6. Switch to new user to enter home directory
Substitute janedoe for the user you created in step 3.
su - janedoe
Create a new directory .ssh and restrict permissions:
Ensure there are no spaces between / and .ssh
chmod 700 ~/.ssh
Use nano, the command-line text editor, to edit the authorized_keys file in .ssh directory by typing:
chmod 600 ~/.ssh/authorized_keys
Type exit to switch back to the root user.
7. Verify the configuration
Check that janedoe can successfully log into the server using SSH.
If successful, you will login to your server using your private key and will not be prompted for a password.
8. Disable root login
Only disable root logins if you have set up SSH keys on the server, otherwise you’ll be locked out.
Edit the SSH daemon file to prevent unauthorized users logging into your server using password authentication.
Login by SSH to your server with your new super-user, for example, janedoe
Use nano, the command-line text editor, to open the SSH daemon file:
sudo nano /etc/ssh/sshd_config
Find PermitRootLogin, it will look like this:
Set it to no using your cursor
ctrl + O then Enter to write the changes to SSH daemon
Now close the file with
ctrl + x
9. Reload SSH
To save the changes, restart the SSH service:
sudo systemctl restart sshd
You are now ready to start using your new cloud server!
