The next step varies based on your chosen setup, we assume you have an SSH daemon running and either:

Have a non-root user already established on your VPS (by default when the VPS image was provisioned)
Have a non-root user created as part of your OS installation
Have root access to your VPS, or OS (installed on VM, or dedicated hardware)

In both of the first two scenarios above, where you have a non-root user to access your node, steps 1 - 7 can be skipped

	Description	Command
	Login - if you already have a non-root user you can skip to step 8 or 9
1	On Mac OS, or Linux open a Terminal session and login to your node, replace <FQDN> with your own Fully-Qualified Domain Name, remove <brackets> OS X - press CMD + SPACE, type 'terminal' press <Enter> Linux - open the Terminal app NOTE: Upon first sign on, you will be asked to add an ECDSA fingerprint, answer yes NOTE: Upon first sign on with root, it may be necessary to change the root password	ssh root@<FQDN> Example Output > ssh root@node01.zentest.win
2	If you're using Windows 7 64-bit and newer, launch PuTTY, enter the Fully-Qualified Domain Name of your node into the "Host Name" field Ensure "Port" is set to 22, "Connection type" is SSH and "Close window on exit" is set to Always Click open when all of the above has been entered When prompted to login (Login as: ) type 'root' without the quotes and press <Enter> NOTE: Upon first sign on, you will be asked to add an ECDSA fingerprint, answer yes NOTE: Upon first sign on with root, it may be necessary to change the root password PuTTY download (external link) - https://the.earth.li/~sgtatham/putty/latest/w64/putty-64bit-0.72-installer.msi
	Add a non-root user on your node
3	Some lite installations of linux do not have sudo installed by default, we need to set that up before proceeding	apt-get install sudo
4	Set a $USERNAME environment variable - change the value of 'zenops' to your preferred username	USERNAME=zenops
5	Add a non-root user, adding to the 'adm', 'systemd-journal' and 'sudo' group as part of this command Create a strong password and re-enter to confirm. DO NOT LOSE THIS PASSWORD! Groups explained adm - allows access to log files in /var/log without using sudo systemd-jounral - allows access to the log via journalctl without using sudo sudo - allows access to run commands as the super user	Do not replace fields starting with $, like the following; it is meant to be copied and pasted without edits NOTE: Windows users on PuTTY terminal can paste by simply right clicking into an open space within the terminal useradd -m -s /bin/bash -G adm,systemd-journal,sudo $USERNAME && passwd $USERNAME If you fail to enter the same password for the confirmation, use the following command to update your password passwd $USERNAME
6	Switch (su) to the new user that has been created. The remainder of the guide will be conducted using the non-root user.	su $USERNAME
7	Change directory (cd) to the non-root user's home directory	cd ~/ You can proceed to Part 3, do not follow other steps that do not apply to your configuration
	Already have a non-root user (therefore skipped steps 1 - 7) SSH into your node, these steps can be skipped if you completed steps 1 - 7
8	On Mac OS, or Linux open a Terminal session and login to your node, replace <USER> with your non-root username and <FQDN> with your own Fully-Qualified Domain Name, remove <brackets> OS X - press <CMD> + <SPACE>, type 'terminal' press <Enter> Linux - open the Terminal app NOTE: Upon first sign on, you will be asked to add an ECDSA fingerprint, answer yes	ssh <USER>@<FQDN> Example Output > ssh zenops@node01.zentest.win
9	If you're using Windows 7 64-bit and newer, launch PuTTY, enter the Fully-Qualified Domain Name of your node into the "Host Name" field Ensure "Port" is set to 22, "Connection type" is SSH and "Close window on exit" is set to Always Click open when all of the above has been entered When prompted to login (Login as: ) type your non-root username and press <Enter> NOTE: Upon first sign on, you will be asked to add an ECDSA fingerprint, answer yes PuTTY download (external link) - https://the.earth.li/~sgtatham/putty/latest/w64/putty-64bit-0.70-installer.msi
	Give your non-root user group permissions (applicable to step 8 or 9 above) DO NOT PERFORM THESE STEPS IF YOU FOLLOWED STEPS 1 - 7!
10	Switch to your root login and enter the root password when prompted	su root
11	Some lite installations of linux do not have sudo installed by default, we need to set that up before proceeding	apt-get install sudo
12	Set a $USERNAME environment variable - change the value of 'zenops' to your non-root username	USERNAME=zenops
13	Modify the non-root user, adding to the 'adm', 'systemd-journal' and 'sudo' group as part of this command Groups explained adm - allows access to log files in /var/log without using sudo systemd-jounral - allows access to the log via journalctl without using sudo sudo - allows access to run commands as the super user	Do not replace fields starting with $, like the following; it is meant to be copied and pasted without edits NOTE: Windows users on PuTTY terminal can paste by simply right clicking into an open space within the terminal usermod -a -G adm,systemd-journal,sudo $USERNAME If you fail to enter the same password for the confirmation, use the following command to update your password passwd $USERNAME
14	Switch to your non-root user login and enter your password when prompted	su $USERNAME
