Neutron has been around for some time and recently i found myself drawn to it being that it had a low barrier to entry for a masternode unlike all other masternode coins at the moment. The community didn't have a guide for setting up a linux masternode so here is a breakdown of the steps i took to get my masternode up and running on a Ubuntu Linux droplet at Digital Ocean.
Word of Warning: Always test you can use a linux wallet before committing all your 25000 coins to it, if you have never used a CLI/Non GUI wallet it is YOUR responsibility to learn what you need to know.. This guide will show you some basic things but you should install a test wallet in a sandbox , send it a coin or two and play with it first before proceeding, don't rush, you don't want to lose it all with a rookie mistake.
Assumptions: Ubuntu 16.04 installed on your VPS and can SSH into it and you are accessing via SSH with a username and password.
VPS Security: if you do not setup access to your VPS using ssh keys and a firewall then i suggest that you make sure you have at least enabled the firewall on your VPS and only allow the required TCP ports incoming for the Neutron Masternode and SSH, you should also define only a single IP as the source address for TCP Port 22/SSH access be it your work or home IP. When you are not accessing the server for maintenance you should block port 22/SSH in your firewall at the VPS console so it is only open for the time required. Also enable 2FA at your VPS if available.
----VPS Setup---
If you need a VPS provider thats only ~$5/month then signup at Digital Ocean and get $10 free credit here when you join (approx 2 months free with a basic VPS).
Create a new droplet, ideally you will use the $10 option as it will allow for longer lifespan but the $5 should be sufficient for some time.
Lets roll.....
---Create a non root user---
Now login to your droplet/VPS host as your root user
Let's add a new non root user :
adduser neutronuserCreate a Password and fill in all other info when asked (you can press enter through all this) and then Y to confirm
Add this user to the sudo group
usermod -aG sudo neutronuserLogout of the server and log in as this new user
---Setup Swap Space---
This is needed to compile Neutrond if you skip this it will fail if you have low RAM.
sudo dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
sudo mkswap /var/swap.img
sudo swapon /var/swap.img--Install Dependencies---
Some may be unnecessary sorry but it works :)

run Neutrond again and wait for blockchain to sync
./Neutrondyou can basically check on the status of the sync by checking the size of blk0001.dat it is approx 563MB at the time of writing this. So check the filesize with the below command until you are convinced that the file size hasn't changed. Allow a few minutes between checks of the file as sometimes sync can stop for a while.
ls -la ~/.Neutron/Neutron.conf---Some safety tips---
check bash history is not saving your commands when you type anything with a space preceding the command
nano ~/.bashrclook inside the ~/.bashrc file for
HISTCONTROL=ignoredups:ignorespaceif it exists then that's great otherwise you can add it anywhere in the file and Ctrl+x to save, you will need to reload bashrc with the following command:
. ~/.bashrcSo now this means that if you start typing a command that contains a password and just put a space in the front of the command as the first character then it will not save to history. i.e
neutronuser@ubuntu:~/#ls -la #this will save to history
neutronuser@ubuntu:~/# ls -la #this will not save to history---Wallet Security---
Encrypt Your Wallet
./Neutrond encryptwallet [SUPERSECRETPASSPHRASE]Restart Neutrond as this will exit the wallet
./NeutrondUnlock Wallet if you need to use any wallet functions
./Neutrond walletpassphrase [SUPERSECRETPASSPHRASE] 120Get your Public Key/Payment Address
./Neutrond getaccountaddress 0Backup your Private Key, either take a copy of ~/.Neutron/wallet.dat and storing it somewhere safe. You can also take your private key to keep somewhere, if you want the actual private key then do the following:
./Neutrond dumpprivkey [ACCOUNT-ADDRESS]Download your wallet.dat using SCP from the command line or windows SCP GUI App. Below is how to download the wallet.dat from the VPS to your home directory on OSX:
scp neutronuser@[VPS-PUBLIC-IP-ADDRESS]:~/.Neutron/wallet.dat ~/wallet.dat So the blockchain sync has completed? Lets move on.
---Generate a Masternode Key---
./Neutrond masternode genkeycopy this into the below [MASTERNODEKEY] field
the default port for the masternode is 32001 so use that or any other you like, just remember the firewall needs to be setup to allow TCP/32001 through
rpcallowip=127.0.0.1
port=32001
masternode=1
masternodeaddr=[YOUR-PUBLIC-IP]:32001
masternodeprivkey=[MASTERNODEKEY]add the above to Neutron.conf
nano ./.Neutron/Neutron.confcopy in the content above into this file with your substituted details and when you are done press CTRL+X then Y to save.
---Send your 25000 coins to the wallet address---
This MUST be in one transaction, if you store your funds on a desktop wallet it should add the fee on top of the amount you send, from an exchange you may beed to test with a small amount like 1NTRN to another address just to confirm how their fees work but more than likely from an exchange you need to add 0.01 to the total amount you want to send.
after you send your coins you can check on the server that they have been recieved by
./Neutrond getbalanceyou can check the transaction list by
./Neutrond listtransactionsMove on once you see your 25000 coins in the balance
---Start up the masternode---
Stop the daemon
./Neutrond stopRestart the daemon
./NeutrondStart the Masternode, if you encrypted your wallet then you will need to unlock it with
./Neutrond walletpassphrase [YOURSUPERSECRETPASSWORD] 120Start up the masternode
./Neutrond masternode startif you did good then you should get a message "successfully started masternode"
to check your node is on the masternode list run the following.
./Neutrond masternode listAnd..... You're done.
Note: I'll update this as i refine the process or if you have suggestions please let me know and ill update the guide.
Thank you for creating this resource for Neutron! NTRN's Future is bright...

Awesome! the neutrond is now underscore but other than that it was extremely helpful!
