Investigating an Ethernet Interface Find a Linux machine to do this on, ideally with a wired Ethernet port (a Raspberry Pi works great for this). For best results the port should be connected to a network via a cable. If you don't have access to such a machine, let me know and I can provide sample output you can use for this question. (a) Determine the current speed being used by your Ethernet adapter. There are various ways you can do this: • On Linux you can check the system boot messages, something like sudo dmesg | grep eth although that might not work on some gigabit drivers. • Another way to check is to install the ethtool utility and run sudo ethtool eth0 (b) Look at the information on your Ethernet device. Often on Linux this will be called eth0 but this can vary for many reasons. Use the command /sbin/ifconfig i. What is your MAC address? ii. Look this up using an OUI lookup tool. Does it match what you expect? iii. What is the default frame size (MTU)? iv. How many bytes have been received (RX)? v. How many bytes have been transmitted (TX)? vi. Has your device seen any collisions? vii. Has your device dropped any packets? (c) If the collision count is low, can you explain why that is?

For the function $H = xy(x + y - 2)$, derive the Hamiltonian system $\frac{dx}{dt} = \frac{\partial H}{\partial y}$, $\frac{dy}{dt} = -\frac{\partial H}{\partial x}$. (2) (a) Sketch the zero level $H = 0$ of the first integral and use (2) to determine the direction of the vector field on this set, putting corresponding arrows on the diagram. (b) Show that there are 4 fixed points, 3 of which lie on the zero level set, $H = 0$. What type of fixed point is the 4th? What is the value of $H$ at this fixed point? (c) Deduce that the $x$-axis is invariant and find the general solution of the system (2) on this line. For the solution satisfying $x(0) = 1$, describe the behaviour as $t \to \pm \infty$? For the solution satisfying $x(0) = 3$, find the value of $t$ at which $x(t)$ becomes infinite.
