Personal Guide to VPS
This will be my go-to guide for whenever I need to setup a VPS instance, so that I don’t have to memorize it by heart.
Creating a new user
adduser lashoun # user-friendly version of useradd usermod -aG sudo lashoun # add to sudoers group
The next commands will be issued as the
sudo apt update sudo apt upgrade
First, to avoid getting locked out, copy the contents of
sudo vim /etc/ssh/sshd_config
sshd_config, uncomment and set those lines with those values:
Port CUSTOM_PORT # changing port helps avoiding script kiddies PermitRootLogin no PasswordAuthentication no # only allow key authentication systemctl restart ssh
Now, let’s put a trap for people knocking on port 22. We’ll use endlessh:
sudo apt install git gcc make build-essentials cd ~; mkdir utilities; cd utilities git clone https://github.com/skeeto/endlessh.git make sudo ./endlessh -p 22 & # launches the trap for port 22
If you don’t feel like tinkering with the system, Docker, and proxies — which I can understand — or if you need only basic selfhosted systems (cloud, calendar, pastebin, etc.), just install Yunohost as root!
