= Assignment 1 =
Based on the information collected, answer the following questions:
# What is the kernel version of Linux on matrix?
# What is the IP address and MAC address of the Linux machine on matrix?
# What is the network mask on matrix?
# What are the network addresses of the Linux machine? (there should be three networks)
# What is the IP address of the gateway for the Linux machine on matrix?
# What is the command to display all the currently loaded kernel modules?
# Where is the file for the kernel module called "e100"?
# What is the MAC address for the network device that has the IP address 192.168.1.254?
# How do you display all the physically network addresses known by a Linux machine?
# What is the MAC address of the network device on the default gateway for the Linux machine on matrix?
:1. What is the kernel version on matrix.

::and ip is 192.168.1.69
:3. What is the network mask on matrix.
::Mask:255.255.255.0
:4. What are the network addresses of the Linux machine? (there should be three networks)
::Kernel IP routing table
