The supplied commands are a sequence of shell commands, and they perform administrative tasks primarily related to network configuration. Here's what each command does:

1. sudo su -:

   • This command switches the current user to the root user (superuser) for administrative privileges.
   • sudo: Runs the command with elevated privileges.
   • su: Stands for "switch user"; by default, it switches to the root account.
   • -: Ensures a full login shell is created for the root user, providing the root environment variables and profile settings.

2. ifconfig:

   • Displays or configures network interface information on the system.
   • When run without arguments (as in this case), it displays details about the system's network interfaces, such as their IP addresses, MAC addresses, and status (e.g., UP or DOWN).
   • Note: On modern Linux distributions, ifconfig has largely been replaced by the ip command.

3. ping 255.255.255.255:

   • Sends ICMP (Internet Control Message Protocol) echo requests (using the ping utility) to the broadcast address 255.255.255.255. This address represents all devices on the local network (broadcast).
   • This command is often used to test the network connectivity to all devices on the local subnet.
   • In most configurations, due to security settings, such packets may be dropped or ignored by systems and network devices.

Summary

The code attempts the following:

1. Elevates to the root user (sudo su -).
2. Displays the network interfaces and configuration information (ifconfig).
3. Attempts to ping and test connectivity to all devices on the broadcast address of the local subnet (ping 255.255.255.255).
