Install Script

For a new install, I built a bash script to tweak a new system out of the box for how I like things:

  1. Builds and installs a color prompt (user and root)
  2. Updates sources.list for a standard Debian Testing install (optional)
  3. Downloads and installs my custom .vimrc file
  4. Downloads and installs my gman1.vim colorscheme
  5. Download here: configure_me.sh | Full URL

Old Kali PS1 color prompts (which are pretty cool).

Boot to CLI

In Debian: 

systemctl set-default multi-user.target # boot to cli (runlevels 2,3,4)
systemctl set-default graphical.target  # boot to graphical (runlevel 5)

sources.list

The entries in this file normally follow this format (example only). 

deb http://site.example.com/debian distribution component1 component2 component3
deb-src http://site.example.com/debian distribution component1 component2 component3

The distribution can be either the release code name (stretch, buster, bullseye, sid) or the release class name (old stable, stable, testing, unstable). If you mean to be tracking a release class then use the class name, if you want to track a Debian point release, use the code name.

  • That means, if you always want to be on stable, even when the current testing (Bullseye) becomes stable, then use stable. If you always want to be on testing, even when Bullseye moves to stable, then use testing.
  • But, if you get on testing (Bullseye) and want to keep it even when it moves to stable, then use the code name, bullseye.

At the time I'm writing this…

Stable is exactly what it means. Testing has been 80-90% okay for me over the years… but it's a pain the sphincter when it's not.

vim colorscheme

Create a text file named gman1.vim (for example) and paste in the text below.

  • Copy your colorscheme file (gman1.vim) into: /usr/share/vim/vim[##]/colors/
  • Set the colorescheme in your .vimrc file (see above)
" Vim colorscheme -- gman1
"
" Created specifically for Python
" Based on PyChimp by Pratheek <pratheek.i@gmail.com>
"
" This colorscheme is specifically created, to work in a translucent
" background provided by terminal and supports 256 color terminals
" Tip -- add <t_Co=256> in your ~/.vimrc to utilize the theme well.

Reinstall GRUB

I triple boot O/Ss… so once in a while one will update and over-write my MBR. To get the correct GRUB into the MBR, boot into the preferred O/S and run (as root): 

# grub-install /dev/sda  ## Assuming sda contains the MBR

Then: 

# update-grub

Done.

fstab NTFS

Options and setup for NTFS partition (sharing / data partition) in Linux. You will likely need to do run the id command from the command line to find your uid and gid. 

UUID=[use blkid to find it] /mnt/data ntfs-3g  user,big_write,uid=1000,gid=1000,dmask=0022,fmask=0011  0  0

Kali: root

Kali made the spectacular decision to drop the default root policy and then not even allow you to configure a root password (i.e., log in as root) when you install.

  • When you install Kali Linux, you’ll be asked to create non-root user that will have admin privileges. Tools and commands that require root access will be run with sudo.
  • So you have to type sudu… sudo… sudo… sudo… (really, guys??).

To configure password-less root rights for your normal user (but you still have no access to applications that are only in root's PATH): 

sudo apt install kali-grant-root
sudo dpkg-reconfigure kali-grant-root

Better: Unlock the root login. Just give root a password, log out, then log in as root: 

sudo su -  # do this as a normal user, give your password; you become root
passwd     # add a password to root's account; log out, log in, shiny

Ah… happiness again in the land of hacker penguins…

Fluxbox

For a quick, lite Debian install…

  1. Install a base Debian system without any desktop environment.
  2. After you can boot to the command line…
  3. Install xorg, then fluxbox (good how-to, except I installed xorg before flux).
