Topology
1. Set Up Environmet
1.1 VMware Workstation
You also can use ESXi / Virtual Box / Hyper-V to set up your virtual lab environment.
1.2 Kali Linux
Download ISO image from https://ift.tt/1xv2Ev9 or download virtual machine from https://ift.tt/2D6en2N
The VM images have a default password of “kali/kali”
1.3 Metasploitable Linux
Metasploitable is an intentionally vulnerable Linux virtual machine. This VM can be used to conduct security training, test security tools, and practice common penetration testing techniques. Download link: https://ift.tt/2jSrhGH
The default login and password is msfadmin:msfadmin.
2. Basic Configuration Environment
- IP Change
- Temporary Change (Immediately Take Into Effect):
- Permanent Change:
- DHCP
auto eth0
iface eth0 inet dhcp
- Static
auto eth0
iface eth0 inet static
address 192.168.2.20
netmask 255.255.255.0
gateway 192.168.2.1
- Gateway Change
route add default gw 192.168.2.1
- DNS Change
echo nameserver 8.8.8.8 > /etc/resolv.conf
2.2 Enable Root Account and Enable SSH Remote Access
By default, in Kali version 2020+, root account is not allow to log in to system. Also SSHD service is disabled.
- change root password
sudo passwd root
- change sshd configure file to allow root log in from remote ssh session
PermitRootLogin yes
- Start SSHD service
- Enable SSHD service in boot.
update-rc.d ssh enable
2.3 Disable Screen Lock
System – Power Management
2.4 Update && Upgrade
apt update -y && apt upgrade -y
apt-get upgradewill only upgrade currently-installed packages;apt upgradewill upgrade currently-installed packages and install new packages pulled in by updated dependencies;- the various
dist-upgradeandfull-upgradevariants will upgrade currently-installed packages, install new packages introduced as dependencies, and remove packages which are broken by upgraded packages.
| Command | Upgrade Current | Install New | Remove Broken |
|---|---|---|---|
apt-get upgrade |
Yes | No | No |
apt upgrade |
Yes | Yes | No |
apt-get dist-upgrade, apt full-upgrade etc. |
Yes | Yes | Yes |
If update && upgrade is too slow, you might need to change your apt source to the one close to your location.
cp /etc/apt/sources.list /etc/apt/sources.list.bak
vim /etc/apt/sources.list
