Setup VPS

1. Update the server

sudo apt update && sudo apt upgrade -y

2. Add SWAP

Add 2GB of SWAP First check to make sure there is not already swap active:

free -h

If the return is 0, you should create and activate the SWAP. Swap: 0B 0B 0B Create SWAP and Activate (only if required):

sudo dd if=/dev/zero of=/swapfile bs=1k count=2048k sudo chmod 600 /swapfile

sudo mkswap /swapfile sudo swapon /swapfile

sudo echo "/swapfile swap swap auto 0 0" | tee -a /etc/fstab sudo sysctl -w vm.swappiness=10

sudo echo vm.swappiness = 10 | sudo tee -a /etc/sysctl.conf

The return of the echo should be: swappiness = 10

3. Firewall

Enable firewall & open ports First check to make sure there is not already swap active:

apt install ufw -y
ufw default deny incoming 
ufw default allow outgoing 
ufw allow ssh
ufw allow 23566/tcp 
ufw enable

4. Install Fail2Ban

sudo apt install fail2ban -y

sudo nano /etc/fail2ban/jail.local

Copy and paste the following config into the file:

[sshd]
enabled = true 
port = 22 
filter = sshd
logpath = /var/log/auth.log 
maxretry = 3

Restart fail2ban:

sudo systemctl restart fail2ban

Reboot the server:

sudo reboot

5. Daemon Configurations

Download latest daemon & Configurations

mkadir vortexa

cd  vortexa

wget https://github.com/AIVortexa/vortexa/releases/download/0.36.2.4/vortexa-linux-0.36.2.4.tar.gz

tar -xvf vortexa-linux-0.36.2.4.tar.gz

chmod +x *
