Welcome to All In One YouTube channel. Today we are going to talk about how to fix
corrupted VPS in Oracle Cloud. You can also use this method to install operating
systems and reset your VPS. Everyone can use this method because there
are no requirements for using this method. You can install these operating systems. Also there are different versions of each
operating system. Now I explain some key features that we use
in video. First one is TFTP protocol. Trivial File Transfer Protocol (TFTP) i
s a
simple protocol used for transferring files over a network. It operates on UDP and is commonly used for
tasks like network booting and firmware updates in devices. Next one is Netboot.xyz. Netboot.xyz is a project that provides a collection
of bootable operating system installers and utilities accessible over a network. It allows you to boot various operating systems
or tools directly from the internet without the need for physical media. This can be useful for tasks like system recovery,
OS
installations or testing different operating systems. Let's see what things we are going to do in
this video. 01.How Corrupted VPS Looks Like. 02.If Your VPS Is Not Corrupted. 03.Creating
Console Connection In Instance In Oracle Cloud. 04.Accessing UEFI BIOS Menu Using Console

in this video. You can f
ind download link of text file in
description. After you click on the download text file
of script link, you can see page like this. Click on link in the page. Now scroll down and you can see "Download
Text File" topic. As say in here, click on "Subscribe YouTube
Channel" button and subscribe YouTube channel and come back here to download text file. So, let's do it. Click on "Subscribe YouTube Channel" button. Now you are going to my YouTube channel. Now subscribe my YouTube channel, If you didn
't
already subscribe it. You can't download text file, if you don't
subscribe my YouTube channel. I don't do anything because I already subscribed. So, let's go back to that page. As say here, we can see "Text File" button
after some time because I subscribed YouTube channel. But if you didn't subscribe my YouTube channel,
you can't see "Text File" button. So, let's wait some time. Now you can see "Text File" button. Click on it. Now you are going to MediaFire website. Click on download button.
Text file is being downloaded now. So, let's start our video. How Corrupted VPS Looks Like. This is Ampere VPS. You can see it now. This is full functioning VPS. Now let's see how corrupted VPS looks like. This command wipes out full disk. So, don't use this command. Now let's see what things are available in
"/" directory. You can see "ls" command isn't worked. This is how corrupted VPS looks like. Now we are going to fix this VPS. If Your VPS Is Not Corrupted. If your VPS is not corrupted, you
can run
commands normally. So, your purpose of watching this video is
resetting VPS, reinstalling OS in VPS or installing another OS. If your VPS is not corrupted, you can do this
work easier. Our main goal is to put UEFI iPXE Bootloader
Into UEFI Interactive Shell. If your VPS is not corrupted, you can do this
using one command. But if your VPS is corrupted, you need to
create TFTP server and download UEFI iPXE Bootloader Into UEFI Interactive Shell using
TFTP server. So, let's see how to put
UEFI iPXE Bootloader
Into UEFI Interactive Shell using one command. Go to "Fixing_Corrupted_VPS.txt" file. Copy "Root Access" command. Go back to VPS. Paste copied command and press Enter. If you have added password, type it and press
Enter. Now we are going to get download link of UEFI
iPXE bootloader. Go to "Fix_Corrupted_VPS.txt" file. Copy "Downloading UEFI iPXE Bootloader" link
and go to your web browser. Go to copied link. Scroll down. Right click on "netboot.xyz-arm64.efi" text. Click on
"copy link address" text. Go back to "Fixing_Corrupted_VPS.txt" file. Replace "URL" of "Directly Putting UEFI iPXE
Bootloader Into UEFI Interactive Shell" command from copied link. Copy "Directly Putting UEFI iPXE Bootloader
Into UEFI Interactive Shell" command. Go back to VPS. Paste copied command and press Enter. If you can see "netboot.xyz-arm64.efi" text,
your command is working. If this command is not working, you need to
use TFTP server method. So let's go to next step. Creating Console Co
nnection In Instance In
Oracle Cloud. This is the "Instance Details" web page of
corrupted VPS. You can create Console Connection to this
instance from here. Usage of Oracle Cloud Console Connection is
remotely troubleshooting malfunctioning Instances. So let's create Console Connection. Scroll down. Click on "Console Connection". The easiest way to access Console Connection
is using Oracle Cloud Cloud Shell. Click on "Launch Cloud Shell Connection". If you are doing this work using an Android
d
evice, please move to your computer or use a RDP connection just like me. Now Console Connection is ready to use. Next we are going to access UEFI BIOS menu. Accessing UEFI BIOS Menu Using Console Connection
In Oracle Cloud. For accessing UEFI BIOS menu, you need reboot
the Instance. Scroll up web page. Click on "Reboot" button. Choose "Force Reboot" option. If you will have a mistake in this process
or lost Console Connection, when you restart process, always use this option, when rebooting
Ins
tance. Now click on "Force Reboot Instance" button. After clicking on it, immediately switch back
to the Console Connection window and press Esc repeatedly until a UEFI BIOS menu appears. Next we are going to set up internet access
on UEFI BIOS menu. Setting-up Internet Connection On UEFI BIOS
Menu. Use arrow keys to select options. Go to "Device Manager" option. Click on down arrow key. Click on Enter. Go to "Network Device List" option. Click down arrow key four times. Click on Enter. Click on
Enter. Go to "IPv4 Network Configuration" option. Click on down arrow key. Click on Enter. Enable "Configured" option. Click on enter enable enable DHCP option click
on down arrow key click on enter go to save changes and exit option click on down arrow
key click on enter click on escape button click on escape button
click on escape button next we are going to access UF interactive
shell accessing UF interactive shell in Oracle Cloud console connection ction I use full
screen mode in console c
onnection window go to boot manager option click on
down arrow key click on enter go to EFI internal shell option click
on down arrow key click on down arrow key key click on enter now you are in UAV interactive shell
go back to fixing corrupted VPS do text file copy selecting device command go back to UA interactive shell paste
copied command and press enter go back to fixing corrupted VPS do text file copy finding
file size command and go back to UAV interactive shell paste copied command and
press enter
if you directly put UAV ipx bootloader into U interactive shell you can see that boot. XYZ arm64 EFI file here so you can go to running
UAV ipx boot loader step but if you can't see NB XYZ arm64 EFI file here you need to
use tftp server method to download UAV ipx boot loader here so let's see how to download
UAV IX boot loader using tfp connection downloading UAV ipx boot loader to UAV interactive shell
using tfdp connection now we need to transfer UAV ipx boot loader to UAV inter in
teractive
shell for this we use tfdp protocol UF interactive shell has tfdp client so we need to create
tfp server and transfer UF ipx bootloader using it I used a lot of tfp server softwares
but none of them worked so I created tfp server using python for this I will show you how
to use my tftp server python script to transfer UAV IP access boot loader in Windows and Linux
first let's see in Windows Windows now we are going to download UAV IX boot loader to
Windows computer open fixing corrupte

go back to fixing corrupted VPS doxt file now we need to open port 69 for tfp server
ufw and dibles are popular firewall management tools these two commands are used to open
port 69 for UDP tr
affic in these tools if you use Yu copy opening Port 69 using Yu command go back to your Linux machine paste
copied command and press enter go back to fixing corrupted VPS do text file if you use
zip tables copy opening Port 69 using epbl command go back to your Linux machine paste
copied command and press enter if you use another firewall management tool you need
to open port 69 for UDP traffic using it go back to fixing corrupted VPS do text file
now we need to restart your Linux machine copy
rebooting command go back to your Linux machine paste
copied command and press enter next we are going to some additional step for opening
Port if you use a Windows or Linux machine created using a cloud provider you need to
set up security rules in that cloud provider to open port if you use router to access internet
on your local windows or Linux machine you need to do port forwarding in router to open
port first let's see how to set up security rules in that cloud provider for opening Port se
tting up security rules in Cloud providers
for opening Port our main task here is opening port for tfp Server also I can't give steps
for cloud providers one by one so I am going to give common steps for for opening Port
69 for UDP traffic these are the steps identify the instance or virtual machine that you want
to open port access the Management console or portal of your cloud provider locate the
networking or security settings for the instance look for the firewall or Security Group associate
d
with the instance find the section for inbound or inass rules add a new rule with the following
details protocol UDP Port 69 source 0.0.0.0 to allow access from all IP addresses save
the changes now you are allowing access from any IP address to Port 169 using UDP protocol
next we are going to do port forwarding in router for opening Port doing port forwarding
in router for opening Port our main task here is opening port for tfp Server also I can't
give steps for all routers one by one so I am
going to give common steps for port forwarding
and Port 69 for UDP traffic these are the steps access your router's configuration Page
by typing its IP address into a web browser the default IP address is often printed on
the router itself or mentioned in the user manual common IP addresses are 192.168.0.1 or 192.168.1.1 enter your router's username and
password to log in if you haven't changed these check the default credentials in the
user manual or on the manufacturer's website look for the
port forwarding or virtual server
option in your router's configuration settings the location of this option may vary depending
on the router's brand and firmware create create a new port forwarding rule by specifying
the following service name tftp internal IP address enter the private IP address of your
windows or Linux machine follow these steps to find private IP address of Windows machine
open search bar type CMD and press enter Now command prompt will be opened go back to fix
in corrupted
VPS doxt file copy finding private IP address command go back to your Windows
machine paste copied command and press enter now you can see private IP address as ipv4
address follow these steps to find private IP address of Linux machine go back to fixing
corrupted VPS doxt file copy finding private IP address command go back to your Linux machine
paste copied command and press enter now you can see your private IP address let's see
other steps protocol UDP external Port 69 internal Port 69 save
the settings now everything
is ready to use let's transfer UAV ipx boot loader to UAV interactive shell sending UAV
ipx boot loader to UAV interactive shell now we are going to send UAV ipx boot loader to
UAV interactive shell now we need to find public IP address of machine that running
tfp server first let's see in Windows Windows open search bar type CMD and press enter you
can see command prompt go back to fixing corrupted VPS doxt file copy finding public IP address
command go back to your
Windows machine paste copied command and press enter you can see
public IP address next let's see in Linux machine Linux go back to fixing corrupted
VPS do text file copy finding public IP address command go back to your Linux machine paste
copied command and press enter you can see public IP address go back to fixing corrupted
VPS doxt file replace public uncore IP and downloading UAV ipx boot loader using tfdp
connection command from public IP address of your windows or Linux machine that runn
ing

your VPS now next we are going to make some modifications in SSH settings adding SSH public
key now installation process is over so if you want you can exit from console connection
and create new one there are several types of authentication methods that can be used
with SSH main methods are password authentication and public key authentication password authentication
is generally
considered less secure than public key authentication because passwords can be
vulnerable to Brute Force attacks or password guessing attempts so we are going to add SSH
public key now first you need to generate SSH key pair there are several ways to do
it I will show you the easiest way go to create compute instance page in your Oracle Cloud
account click on save Private key and save public key now you have new SSH private and
public key pair now let's add this go back to console connection pre
