## Access your machine

Open the PowerShell editor and type the following command:

```
ssh -i [ssh_key_place] ubuntu@[machine_ip]
```

Example:

```
ssh -i c:\users\user\desktop\ssh-key-2021-09-15.key ubuntu@0.0.0.0
```

> If you get an error while trying to connect to your cloud machine, you can fix it by right-clicking on ssh-key, select properties > security > advanced > remove inheritance, and delete all other users, keeping only your Windows user.

After you connect, run the following commands to add firewall rules into Ubuntu:

```
sudo apt install firewalld
sudo firewall-cmd --zone=public --add-port=7777/tcp --permanent
sudo firewall-cmd --zone=public --add-port=7777/udp --permanent
sudo firewall-cmd --reload
```

Download FileZilla, and follow the steps below to connect to your cloud machine using your ssh-key:

## Create Build

In Unity, access **File** > **Build Settings** > **Select Linux** > **Mark Server Build**. Wait for the build to finish, and then upload your files with FileZilla.

This tutorial uses a server folder, but this is optional.

Use the following commands:

cd server
chmod +x ./[your_project_name].x86_64
./[your_project_name].x86_64
```

Your server should now be running!
