<p> <h2>Purpose of the assignment</h2> Learn how to setup network interfaces in most modern Linux distributions (NetworkManager). </p> <p> <h2>Quick instructions</h2> Set a static IP in NetworkManager, set a static IP and DNS server in /etc/network/interfaces. You'll get both IP's when you execute script run_test.py. </p> <p> <h2>Instructions</p> <ol> <li>From the directory with images of virtual computers, download the following:<br/> maliNetworkManager, maliBrezNetworkManager, SimpleArbiterDhcp.</li> <li>Set the network for virtual computers, so that SimpleArbiterDhcp's 1. nework interface is connected to the same network, as the only network interface for maliNetworkManager and maliBrezNetworkManager,<br/> SimpleArbiterDhcp's 2. network interface will be connected to a NAT or a physical network, where the address and route (gateway) to the internet is obtained via DHCP.</li> <li>Start SimpleArbiterDhcp. Sign in as user "tester" with password "SedemKrogovPekla".</li> <li> <img alt="slika-04" src="https://lusy.fri.uni-lj.si/kpov-public-svn/kpov-public/kpov_judge/tasks/set_ip_static_dhcp/howtos/images/04.png" style="width: 800px; height: 600px;" /><br/> Use command <pre>ping 193.2.1.66</pre> to check if SimpleArbiterDhcp is connected to internet. If you get ping reply, you're connected to the internet. Cancel the ping with combination CTRL+C.<br/> If SimpleArbiterDhcp doesn't have internet access, change the network settings in Virtual box for 1. and 2. network interface, then restart the virtual computer. </li> <li>Run the script run_test.py.</li> <li>Enter "03.predvaja" as assignment name.</li> <li>Read the maliNetworkManager's static IP . Leave SimpleArbiterDhcp running in the background until you have setup the maliNetworkManager.</li> <li>Start maliNetworkManager.</li> <li> Sign in the GUI(graphical user interface) using username "student" and password "vaje".</li> <li><img alt="ikona network manager" src="https://lusy.fri.uni-lj.si/kpov-public-svn/kpov-public/kpov_judge/tasks/set_ip_static_dhcp/howtos/images/10.png" style="width: 800px; height: 600px;" /><br/> Right click on the icon for network settings.</br> <li> <img alt="Menu NetworkManager" src="https://lusy.fri.uni-lj.si/kpov-public-svn/kpov-public/kpov_judge/tasks/set_ip_static_dhcp/howtos/images/11.png" style="width: 800px; height: 600px;" /><br/> Choose "Edit Connections"</li> <li> <img alt="Menu NetworkManager" src="https://lusy.fri.uni-lj.si/kpov-public-svn/kpov-public/kpov_judge/tasks/set_ip_static_dhcp/howtos/images/12.png" style="width: 800px; height: 600px;" /><br/> Click "Edit"</li> <li> <img alt="Menu NetworkManager" src="https://lusy.fri.uni-lj.si/kpov-public-svn/kpov-public/kpov_judge/tasks/set_ip_static_dhcp/howtos/images/13.png" style="width: 800px; height: 600px;" /><br/> In tab "IPv4" change the "Method" to "Manual". Click "Add". Set the SimpleArbiterDhcp's static IP as static IP A.<br/> Add Arnes DNS: 193.2.1.66 to DNS servers. </li> <li>Click "Save"</li> <li>Switch to SimpleArbiterDhcp. Click "Enter" or "OK".</li> <li>Read maliBrezNetworkManager's IP . Click "OK". Read the DNS server's address .</li> <li> Switch to maliBrezNetworkManager. Switch to first console using combination CTRL+ALT+F1. Sign in as root (su) with password "kaboom".</li> <li> Open the file /etc/network/interfaces. Edit the settings according to the information you got on SimpleArbiter. Entry for network interface should look something like this:<br/> <pre> allow-hotplug eth0 iface eth0 inet static 10.0.1.2 netmask 255.255.255.128 dns-nameservers 10.0.1.5 </pre> </li> <li> Save the settings. Use the command <pre>reboot</pre> to restart maliBrezNetworkManager. On boot the NetworkManager reads which network interfaces are configured in /etc/network/interfaces. After that NetworkManager doesn't manage these interfaces anymore.</li> </li>Press OK on SimpleArbiterDhcp. If all went ok, you have completed this assignment.</li> </ol> </p>
