* Linux Kernel information
= Procedure =
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0 eth0
* From the output of the /sbin/route command, you should be able to tell which networks (LANs) your machine is directly connected (the 1st column) and which gateway (the 2nd column) your machine could be used should use to reach other networks. Consult the "man" page for "route" for more details.
* If there is no "Gateway" for your machine, your machine can only communicate with other machines that are physically connected.
* Any two physically (or directly) connected network machines must know each other's physical network address (i.e. MAC address) before that can start exchanging data. The MAC address exchange process could occur automatically (default) or manually (to be done by the system administrator). To display the list of MAC address known to your machine, type the command "/sbin/arp". Record the output for later use:
raymond@matrix:~> /sbin/arp -n

= Questions =
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?
