NAD710 Lab #01

NAD710 Lab #01:

1. What is the kernel version of Linux on matrix?

I am a little unsure whether the desired answer is the version or the release of the kernel, as it is a common contraction for people to say 'version' or 'version number' when what they actually mean is the relase. As such, I provide both answers.The kernel version on Matrix is '#1 SMP Tue Feb 12 09:16:51 EST 2008', while the release is '2.6.18.8-0.5-default'.

2. What is the IP address and MAC address of the Linux machine on matrix?

The IP address of the eth0 interface on Matrix is '192.168.1.56', while the MAC address is '00:03:47:E9:89:BF'.

3. What is the network mask on matrix?

The network mask of the eth0 interface on Matrix is 255.255.255.0.

4. What are the network addresses of the Linux machine? (there should be three networks)

I belive I might be misinterpretting this quesiton, because as far as I can see, this machine is connected to two networks: the 192.168.1.0/24 network, and the 127.0.0.0/8.

5. What is the IP address of the gateway for the Linux machine on matrix?

The gateway used by matrix is located at the IP address 192.168.1.254.

6. What is the command to display all the currently loaded kernel modules?

The command 'lsmod' will show the currently loaded kernel modules.

7. Where is the file for the kernel module called "e100"?

The file for the e100 kernel module is located at '/lib/modules/2.6.18.8-0.5-default/kernel/drivers/net/e100.ko.

8. What is the MAC address for the network device that has the IP address 192.168.1.254?

The MAC address of the machine whose IP address is 192.168.1.254 is 00:0E:0C:7F:84:6F.

9. How do you display all the physically network addresses known by a Linux machine?

The command 'arp', located on matrix in the '/sbin/' directory, when executed using the form 'arp -a' will show all physical layer addresses of neighbouring machines that have been cached by the local machine.

10. What is the MAC address of the network device on the Linux machine on matrix?

This question appears to overlap with #2? Maybe I am misunderstanding it? It appeast to me that the MAC address of this machine* is '00:07:E9:F6:36:1f'.

* I completed portions of this lab on two different occasions, and was not logged onto the same node during the writing of the answer to question #2 as during the time of the writing of the answer to question #10.
