# Random commands

**MongoDB setup**: ditch all the bullshit tutorials / Official MongoDB walkthrough

Easy way to install is :

```
sudo apt-get update
sudo apt install mongodb
sudo systemctl status mongodb
```

**#If you cannot reach any network (in NAT mode), try:** 

```
sudo dhclient eth0
```

**#Mouse and keyboard dead after booting**

```
PRESS SHIFT AT BOOTING AND ENTER ADVANCED OPTIONS

sudo apt-get install xserver-xorg-input-all

REBOOT AND THIS SHOULD SOLVE THE PROBLEM.
```

```
sudo dpkg-reconfigure kali-grant-root
