Add the Mono repository to your system

To install Ozeki Installer first, you need to get some dependencies to perform the installation. The first one is the Mono, which is an open-source implementation of Microsoft's .NET Framework. This product is crucial for running Ozeki Installer. To get the latest version of Mono, you have to add the repository to your system as you can see it on Figure 2 below. These commands can be found on the official Mono website:

sudo apt install gnupg ca-certificates
sudo apt-key adv --keyserver hkp:// 
--recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb stable-bionic main" | 
sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update

Finally, you need to enable the appropriate ports on your linux firewall in order to access Ozeki 10 from the outside. To do this, you need to run the following commands. 9543 is the http port and 9544 is the websocket port, 9545 is the https port and 9546 is the secure websocket port.

sudo iptables -I INPUT -p tcp --dport 9543 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 9544 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 9545 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 9546 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 9515 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 9516 -j ACCEPT
