Ubuntu On Segfault

in this repo you will know how to run Ubuntu on Segfault Server.

if you don't know this server check this https://github.com/mrx7014/SSH-KaliLinux

---

Let's GOOOOOO !

• First open your server and update it

sudo apt-get update -y ; sudo apt-get upgrade -y

• After this you should use tmate, because when you use it you will be able to use Ubuntu and Kali at the same time.

• To use it just type tmate in terminal and copy ssh session to connect to server by it again.

---

• This is some tricks to use tmate and create two tabs

• To create a new tab of tmate use this --> ctrl + b + c

• To move between tabs use this --> ctrl + b + "number of tab"

you will see a number of tab at bottom in the green line

---

• Then enter this command on terminal to install requirements

IMAGE="ubuntu-22.04-server-cloudimg-amd64.img" ; sudo apt-get install cloud-image-utils libguestfs-tools

• Now create .vm/ubuntu directory.

mkdir -p ~/.vm/ubuntu &>/dev/null
cd ~/.vm/ubuntu

• Now create metadata.yaml file.

cat >metadata.yaml <<-__EOF__
instance-id: iid-${SF_HOSTNAME}01
local-hostname: ${SF_HOSTNAME}-guest
__EOF__

• Now Create an SSH key and configure the VM. The host's /sec is shared with the VM:

[[ ! -f ~/.ssh/id_ed25519 ]] && ssh-keygen -t ed25519 -N "" -f ~/.ssh/id_ed25519 
cat >user-data.yaml <<-__EOF__
#cloud-config
users:
  - name: root
    lock_passwd: false
    hashed_passwd: '$(echo segfault | mkpasswd -m sha-512 -s)'
    ssh_authorized_keys:
      - $(cat ~/.ssh/id_ed25519.pub)
bootcmd:
  - mkdir -p /sec
mounts:
  - [ host0, /sec, 9p ]
__EOF__
cloud-localds seed.img user-data.yaml metadata.yaml

• Install & Download cloud images:

[[ ! -f "${IMAGE}" ]] && wget "https://cloud-images.ubuntu.com/releases/jammy/release/${IMAGE}"
qemu-img resize "${IMAGE:?}" 32G

• Now you can start using ubuntu image,but....Let's do some tricks

• Enter this command on terminal to make a shortcut with bash script to start a image in an easy way.

cd ; touch start_ubuntu.sh ; echo "cd .vm/ubuntu ; qemu-system-x86_64 \
    -m 2G \
    -nographic \
    -device virtio-net-pci,netdev=net0 \
    -netdev user,id=net0,hostfwd=tcp::2222-:22 \
    -drive "if=virtio,format=qcow2,file=ubuntu-22.04-server-cloudimg-amd64.img" \
    -drive "if=virtio,format=raw,file=seed.img" \
    -virtfs local,path=/sec,mount_tag=host0,security_model=passthrough" >> start_ubuntu.sh ; chmod +x start_ubuntu.sh

- Note: Tag -m pointing to size of server memorey,if you have 2 GB RAM "at a usual of server keep it,And if you have more than 2GB of RAM change the number "2" to what you want

• Now you can start a server by:

./start_ubuntu.sh

• To stop server use halt

it will take sometime at first booting,Don't worry

---

• Now after it booting and ask you about user name and password type this:

• Username : root

• Password : segfault

• Now server is started.

---

Now let's update and setup server.

• Now we will update and setup server for everything.

• Just enter this command into the server

apt update ; apt install sudo ; sudo apt-get update -y ; sudo apt-get full-upgrade -y ; sudo apt install curl

---

Now if you facing any errors with this ubuntu version you can use DistroBox and install Ubuntu with docker via it and use Ubuntu or any other distro.

---

First:

• We should install Docker.So,Enter this command in terminal

sudo apt install docker.io

• After this install DistroBox

curl -s https://raw.githubusercontent.com/89luca89/distrobox/main/install | sudo sh

• After installation is completed now learn how to install Ubuntu 23.04

distrobox create -i ubuntu:23.04

• After installation is completed,Enter this command to open Ubuntu

distrobox enter ubuntu-23-04

It takes some time at the first installation.

• After it completed you can use Ubuntu easily.

---

• If you want to use another distro just type distrobox -i create <distro name:version>

Check DistroBox repo if you want to know more about it Here

---

• To use /sec/root directory in ubuntu just enter:

cd /run/host/sec/root

• if you wanna make a simple customize to server bash shell use this:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/ohmybash/oh-my-bash/master/tools/install.sh)"

• if you want another theme check oh-my-bash repo https://github.com/ohmybash/oh-my-bash
