You may tried all methods to make your Linux VM in Virtual Box full screen but nothing worked.Right? I also encountered the same issue, so here is the solution that worked for me. I was using Kali Linux and by default the guest additions comes preinstalled but that didn't solve my problem. I was not getting the window full screen. The below screenshot is before solving the issue. I tried to install the guest additions manually and noticed that the OS was unable to find the kernel headers. Try the following steps to fix. 1) Update the modules and packages. sudo apt update -y && apt upgrade -y && apt dist-upgrade 2) Install the headers. sudo apt install linux-headers-$(uname -r) 3) Now install the guest additions tool.
Smurf attack.
Smurf is a DoS attacking method. In this flood attack, it floods the victim with the ICMP echo packets instead of TCP SYN packets. Also, it is a spoofed broadcast ping request using the victim IP address as the Source IP.
Most of the modern devices can deter these kind of attacks and SMURF is rarely a threat today.
#hping3 -1 --flood --spoof <target> <broadcast_address>

#hping3 -1 --flood --spoof <target> <broadcast_address>
Fraggle attack.
Similar to Smurf attack, but instead of using ICMP, Fraggle uses UDP packets over UDP ports 7 and 19. Also will broadcast a UDP packet using spoofed IP address of the victim. All the devices on the network will then respond to the victim similar to the Smurf attack.
Land attack
In this, the attacker sends spoofed SYN packets to the victim using the Victim's IP address and both source and destination IP. This results in the system constantly replying to itself can crash the system.
#hping3 -c <packet_count> -s <src_port> -d <dst_port> --flood -a <victim_IP source spoof> <victim_IP>
#hping3 -c <packet_count> -s <src_port> -d <dst_port> --flood -a <victim_IP source spoof> <victim_IP>
