I recently covered my Firefox setup, which is a standard setup I use for day2day as well as CTF's. Over the Advent of Christmas 2 I started using Ubuntu as my base OS instead of Kali. In this post I will be describing the tools I install and how I install them.
APT/Snap Packages
After running a apt-get update I run the below to download tools from the Ubuntu Repos..
sudo apt-get install wireshark vim binutils dnsutils tmux zsh python3-pip john hashcat docker.io docker-compose lxd-tools lxd chromium-browser openvpn radare2 gdb tcpdump mtr-tiny aircrack-ng nikto gobuster steghide stegosuite p7zip dirb remmina virtualbox virtualbox-dkms virtualbox-ext-pack virtualbox-guest-additions-iso nmap curl wget git htop vim ruby ruby-dev netcat cifs-utils smbclient libssl-dev libbz2-1.0 libbz2-dev libbz2-ocaml libbz2-ocaml-dev hydra -yThis installs a number or required packages for some of the tools below as well as some tools.
Even though I prefer Firefox it is always good to have chromium just in-case there is any weirdness. As well as the above I also install Visual Studio Code via snap
sudo snap install code --classicOhMyZsh
Recently I have been enjoying zsh. To get zsh working in a nice way I use OhMyZsh which can be installed via the below command.
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
Cloning Oh My Zsh...

➜ ~ vim .zshrc
In the above I run vim .zshrc to change the theme to fino-time which is the theme I prefer.
# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="fino-time"
You can browse the theme here https://github.com/ohmyzsh/ohmyzsh/wiki/Themes.
Rustscan
Rustscan is great addition to the tool box. It is a hell of a lot faster nmap . You can get Rustscan from their GitHub Release Page as a debian package, once downloaded you can use dpkg to install.
╰─○ sudo dpkg -i Downloads/rustscan_2.0.1_amd64.deb

BurpSuite
Burp is key tool for many CTF's and web based testing. First we need to download the latest release from https://portswigger.net/burp/communitydownload . The Community downlod is a shell script that launches the installer.
sh -x Downloads/burpsuite_community_linux_v2020_12_1.sh
Once installed you can search the launch for it
SecLists
One of the useful things in Kali is the wordlists that it comes with, to get these onto our Ubuntu box we can run the below.
╰─○ git clone https://github.com/danielmiessler/SecLists.git
Cloning into 'SecLists'...
remote: Enumerating objects: 9535, done.
Receiving objects: 100% (9535/9535), 779.68 MiB | 9.24 MiB/s, done.

Updating files: 100% (5336/5336), done.
Rock You
Under the Passwords directory of SecLists the infamous rockyou.txt is conatined with a compressed tar.gz. To decompress this and put it to the root of SecLists ( lets face it we want it in a quick to access directory as we use it loads... ) we can run the below commands.
╭─tony at jumper1 in ~
╰─○ tar -zxvf SecLists/Passwords/Leaked-Databases/rockyou.txt.tar.gz
rockyou.txt
╭─tony at jumper1 in ~
╰─○ mv rockyou.txt SecLists/
Ghidra
Ghidra has become a great too from the NSA which can be used for reverse engineering and can be downloaded from https://ghidra-sre.org/, once downloaded we will need to unzip.
╰─○ unzip Downloads/ghidra_9.2.1_PUBLIC_20201215.zip
Archive: Downloads/ghidra_9.2.1_PUBLIC_20201215.zip
creating: ghidra_9.2.1_PUBLIC/
Before running we will need to install Java Developement kit ( JDK ) from APT.
sudo apt-get install default-jdk -y
Once installed we can run the below to launch Ghidra
╰─○ ~/ghidra_9.2.1_PUBLIC/ghidraRun
MetaSploit
This is the like Burp is a corner stone of pen testing / CTF's. The easiest way to install this is to use the installer from the Rapid7 GitHub Page.

Run msfconsole to get started
At first run you will be prompted to setup a database which I recommend doing.
╰─○ msfconsole
** Welcome to Metasploit Framework Initial Setup **
Please answer a few questions to get started.
Would you like to use and setup a new database (recommended)? yes
====================================================================
Running the 'init' command for the database:
Creating database at /home/tony/.msf4/db
Starting database at /home/tony/.msf4/db...success
Creating database users
Writing client authentication configuration file /home/tony/.msf4/db/pg_hba.conf
Stopping database at /home/tony/.msf4/db
Starting database at /home/tony/.msf4/db...success
Creating initial database schema
====================================================================
It also sets up a username/password for the Metasploit webserver, however I have never used this.

WPScan
wpscan is a ruby application for scanning wordpress sites. Again this is a key one for CTF's and can installed via
╰─○ sudo gem install wpscan
Evil-winrm
Evil-winrm is a util for exploiting windows boxes. Again this a ruby application that can installed via
╰─○ sudo gem install evil-winrm
John The Ripper
Although we installed john above the default Ubuntu install seems to be missing things like gpg2john... To fix this we can install the latest version from GitHub.
╰─○ git clone https://github.com/openwall/john.git

PyCTF-Helper
This is a flask application that I have developed as I got fed of having to change ip's/ports of reverse shells. The default page returns the reverse shells with the IP you hit the application on making it dynamic, it also has a upload function for data exfiltration.
This can be install by cloning the repo, installing the requirement and then using the run.sh to start the application.

IPv4 Forwarding
To enable IPv4 forward we have two options. We can set it runtime using
╰─○ sudo sysctl -w net.ipv4.ip_forward=1or we can set it so it gets activated at boot
╰─○ sudo sed 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/g' -i /etc/sysctl.conf
OWASP ZAP
Another Web Application Scanner, this can be downloaded from https://www.zaproxy.org/
╰─○ sudo sh -x Downloads/ZAP_2_10_0_unix.sh
Again like burp this launches a GUI installer
Again you can search the launcher for zap and launch
Thats All For Now
That is all for now but as I continue to use Ubuntu for TryHackMe I will add to this post, so keep checking back!
Now this is a rough and ready, you will find different guides that suggest /usr/local/bin or /opt for installing the items we installed from source. If you want to you can read more here about the Linux File System Layout
If you have any suggestions, corrections or questions then drop me a tweet or dm @apjone
