:1. [[findone]]What is the kernel version on matrix.
::lsdaly@matrix:~> uname -r
::2.6.18.8-0.5-default

:2. What is the IP address and MAC address of the Linux machine on matrix?
::from:  /sbin/ifconfig
::mac address is  00:0E:0C:74:9C:F9
::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
::Destination     Iface
::192.168.1.0     eth0
::169.254.0.0     eth0
::127.0.0.0       lo

:5. What is the IP address of the gateway for the Linux machine on matrix?
::Destination     Gateway
::0.0.0.0         192.168.1.254

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

::lsdaly@matrix:~> /sbin/lsmod
::Module                  Size  Used by
::nfs                   236268  4
::lockd                  73192  2 nfs

:7. Where is the file for the kernel module called "e1000"? (changed from e100)

::daly@matrix:~> /sbin/modinfo e1000
::filename:       /lib/modules/2.6.18.8-0.5-default/kernel/drivers/net/e1000/e1000.ko

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

::lsdaly@matrix:~> /sbin/arp -n
::Address                  HWtype  HWaddress                       Iface
::192.168.1.254            ether   00:0E:0C:7F:84:6F               eth0

:9. How do you display all the physically network addresses known by a Linux machine?
::lsdaly@matrix:~> /sbin/arp -n

:10. <What is the MAC address of the network device on the default gateway for the Linux machine on matrix?
::From question 5: Gateway IP is 192.168.1.254
