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

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.
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.

See IP Info (pick one, they basically do the same thing):
ifconfig -a # Debian net-tools pkg ls /sys/class/net # ls interface names ip a ip a show ip a show eth0
You can set up as many network configs for as many interfaces as you want. Just set them up, comment them out, and when you want to use one remove the # and bring it up.
/etc/network/interfaces.# +-------------------------+ #
# | Wired Network Interface | #
# +-------------------------+ #
# Comment out these lines if you want to manually bring up your network
allow-hotplug eth0 # bring up the interface on a hotplug event like plugging in a usb cable
auto eth0 # bring up the interface on boot
## The following w/o auto or allow-hotplug requires manual up.
## [1] STATIC (replace subnet with your own):
#iface eth0 inet static

Manually bringing your network up and down (nixCraft has a good explanation):
Generic Method:
ifdown eth0 # Turn off eth0 ifup eth0 # Turn on eth0
Debian Method (as root):
/etc/init.d/networking restart # Restarts network interfaces, or stop/start... /etc/init.d/networking stop # Stops network interfaces /etc/init.d/networking start # Starts network interfaces systemctl restart networking # For those with lovely systemd systemctl status network # See status of network systemd
Debian, overview:
ifup and ifdown control interfaces that are listed in /etc/network/interfaces.ifconfig directly controls network interfaces (much like the newer ip command)
The ifupdown package: high-level network configuration
ifup and ifdown commands may be used to configure or deconfigure network interfaces based on interface definitions in the file /etc/network/interfaces.ifup eth0 based on eth0 configuration in /etc/network/interfaces.ifupdown will wrap ifconfig with the network configuration files (i.e., ifdown or ifup will execute ifconfig down or ifconfig up inside it). That means: ifup eth0 will fetch the interface config file and bring up the interface with the correct IP address, mask, routes etc. ifconfig eth0 up would just start the interface with no IP, etc. (important for sniffing in monitor mode because you don't want an IP address, etc.; you want an open broadcase).
The ifconfig command: a low-level network command (and deprecated, sadly)
ifconfig up eth0 activates eth0 but does not setup IP addresses, etc.ifup eth0 sets up IP addresses and other options based on the interface's configuration in /etc/network/interfaces.
Usage of the ip command:
apt install net-tools.[1] Assign an IP address to a specific interface:
ip addr add 192.168.0.100/24 dev eth0
[2] Bring up the interface link (do NOT skip this step or you will get a “Network is unreachable” error!):
ip link set eth0 up
[3] Bring up the interface link:
ip route add default via 192.168.0.1
[1-3] All in one place… looks like this:
ip addr add 192.168.0.100/24 dev eth0 ip link set eth0 up ip route add default via 192.168.0.1
Note on Persistence: This will only set up your network for your current work session. You'll lose it on reboot.
ip (like the old net-tools ifconfig stuff) interacts with /etc/network/interfaces, so put all your network configuration information there and just up/down your network with these commands: /etc/init.d/networking restart # Restarts network interfaces, or stop/start... /etc/init.d/networking stop # Stops network interfaces /etc/init.d/networking start # Starts network interfaces
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.
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…
