How to order free 4 core VPS and unlock internet access
When you order any dedic or VPS, it always comes with all internet access opened by default. Here we get machine with almost everything closed (except port 22 for SSH). Every port is blocked in Oracle Cloud panel and in Ubuntu.
If you install nginx on it, it will say in webbrowser that site is offline. Read next 16 steps to unlock all ports.
Go to https://cloud.oracle.com/ and login to your account. Click on ‘Create a VM instance’.
Click on ‘Edit Image and shape’.
Click on ‘Change image’.
Select ‘Canonical Ubuntu’ and click ‘Select image’.
Click on ‘Change shape’.
1. Select shape ‘Ampere’
2. Unroll options
3. Change OCPUs number to 4, it will automatically change RAM to 24 GB
4. Tick ‘VM.Standard.A1.Flex’
5. Click ‘Select shape’
For next step machine configuration step, you must have SSH key pair. If you already have one, you can skip next 3 steps.
To generate key pair you need ‘Git Bash’. You can download it here: https://git-scm.com/download/win
Run Git Bash using Windows Search. Just type ‘git’, it should find it.
In Git Bash window type:
ssh-keygen.exe -t rsa
It will generate SSH key pair and save it in your Windows user directory, in subdirectory .ssh. This directory may be hidden (depends on Windows settings), so you can’t easily navigate there. In this case, you can open any directory in Windows explorer, click on address bar, type:
and click Enter. It should open folder with your id_rsa.pub file. You can copy it on desktop or to Downloads folder, to make it easy to find.
On Oracle page scroll to ‘Add SSH Keys’ and select option ‘Upload public key files (.pub)’.
Select file ‘id_rsa.pub’ we generated in previous 3 steps in file picker (button ‘Browse’). Oracle will upload it to your new VPS. Git Bash with automatically login to your server using this key – using all keys which are in .ssh directory – when you use ‘ssh’ command in it.
Your machine should change status to ‘Running’ within 1 minute. On right top side of page, there will appear IP of your server. Copy it. We will use it later.
There will also appear ‘Virtual cloud network’ with some random name. Click on it.
Click on Subnet name – again some random value.
Click on Default Security List name – again some random value.
Click ‘Add Ingress Rules’.
In ‘source CIDR’ type:
and click ‘Add Ingress Rules’.
Network TCP – like Tibia and www – traffic is unlocked in Oracle Cloud panel. You may also unblock UDP protocol traffic, if you plan to host TeamSpeak or other application which uses UDP.
Now we got to unlock traffic in Ubuntu. Open Git Bash and type:
with your server IP in place of x.x.x.x, like ssh email@example.com
On first connection it will ask you, if you are sure that you connected to valid server. Type ‘yes’ and press Enter.
You are now connected to your VPS, but you still can’t run web server or OTS on it. Type:
iptables -I INPUT -j ACCEPT
iptables-save > /etc/iptables/rules.v4
It will unlock all incoming traffic in Ubuntu.
