MACS Network workshops Understanding Internet connections Workshop 1 Check characteristics and quality of an available Internet connection What is the Interface to Internet? How fast is it and what is the bandwidth? How much does it cost? Is the announced bandwidth respected? What are the IP addresses used? Proximus solution ADSL or VDSL model + router = B-BOX Scarlet solution Telenet & VOO solution Used COAX cable (TV + digital + …) Modem/Router with phone lines VUB solution SPEEDTEST.NET Workshop 2 Use a home WiFi router Configuring the router with SSID, DHCP range, Firewall rules, DHCP IP window, WiFi channel, … Home network Initial configuration Use WIRE to LAN port!! Modem or RMA net Initial screen example Intial IP address will be something like 192.168.x.y x = 0 or 1 or 2 Change x to something else NO modem in router! Connect to whatever network Powerline solu OK for HOME NOK at RMA! WiFi configuration Standard: IEEE 802.11 Data rates are different for versions a/b/g/n using 1 or more channels For this course you are allowed to use 1 channel ONLY! => limit the bandwith! Problem: what channel to use! http://www.howtogeek.com/197268/how-to-find-the-best-wi-fi-channel-for-your-router-on-any-operating-system/ Default is 6 !!!!! inSSIDer 3.1.2.1 InSSIDer 4 is NOT for free anymore! Also free apps available for Android free Wifi Analyzer App for Android Workshop 3 Use a PC and Mac as router How to do? What are the IP addresses? How fast is it? Workshop 4 Use a smartphone as router What are the IP addresses used? How fast is it? Reporting 1 Power Point report Need to see Screenshots (gif) Photos Drawings with details Reporting 2 Email to [email protected] BEFORE the deadline Complementary info Missing team members? Time to do? Unsolved issues? Need for assistance? How to specify IP addresses (range) Left fixed Subnet mask bits Start address End address 10.0.0.0/8 8 255.0.0.0 10.0.0.0 10.255.255.255 192.168.10.1/24 24 255.255.255.0 192.168.10.0 192.168.10.255 10.67.151.0/24 24 255.255.255.0 10.67.151.0 10.67.151.255 10.67.151.125/32 32 255.255.255.255 10.67.151.125 10.67.151.125 example 10.67.151.0/24 24 = the number of fixed left bits of the 32 bit address (IPv4) Network mask 11111111.11111111.11111111.00000000 255 .255 .255 .0 Home and room networks Using private address range 192.168.0.0/16 Individual nets 192.168.x.0/24 x = 0 …. 255 DO NOT USE x = 0, 1, 2 = default values of home routers Use different x for each subnet when connecting to VUB net General network description Room or home details DHCP range PC Smartphone Tablet … Static IP address Printer Server … DHCP range 192.168.20.115 – 192.168.20.125 Each router requesting a dynamic address 10.67.151.70 10.67.151.1 WAN LAN 10.67.151.125 Be capable of checking what address has been received! 10.67.151.140 192.168.20.1 Final presentation With your team Thursday Dec 16 afternoon 10 minutes presentation 20 minutes QA The purpose is to verify if every team member knows all the details.
