    Episode 231: Networking Part 2 with Steve Ovens

    In this episode Steve joins us again to discuss networking. Building on the knowledge from our last episode we dig further into ipv6 and other network technology!


    -- During The Show --

    01:00 - VLAN question - Scott


    Management VLan is for admin not printers etc
    Set the switch to only allow access on the management VLan
    Use firewall rules to allow or deny cross VLan access


    08:10 - Replace Unify with TP Link Omada? - Charlie


    Checking it out, will get back to you


    09:00 - Just FYI problem accessing Wireguard tutorial - Paul


    New Wireguard Tutorial


    09:30 - What Router Should I buy? - Nik


    Netgate SG-1100


    12:15 IPv4


    Broadcast traffic - sends a packet to everyone, not forwarded by routers
    Broadcast Domain - Any computer that can hear a broadcast packet
    ARP Table - Table that matches switch port to mac address
    Computers also keep ARP Tables - Including Host Name, MAC Address, IP Address
    Rebooting a switch will cause it to rebuild the ARP Table
    Private IP Addresses - IPv4 Addresses set aside for internal networks
    RFC 1918
    NAT - Network Address Translation - Public IP Private IP
    [IP Chicken](ipchicken.com)
    Router typically hands out DNS Server+IP Address+Hostname


    30:00 IPv6


    IPv6 packet types


    Anycast
    Multicast
    Link-Local

    IPv6 Anycast - Send out a packet to an IP address, expecting multiple devices to have the same IP Address but only the closest responds
    IPv6 Multicast - Tries to only hit intended IP addresses
    Link-Local - Automatically assigned, non route-able, Required for IPv6
    Unique-Local - Private or Public route-able IP address
    Host bit of IPv6 identifies your device across networks


    41:50 Reading IPv6


    First hextet = IANA Assigned prefix
    Second hextet = Your Geographical region
    Third hextet = Your ISP
    Fourth hextet = Your Network

    Leading zeros can be omitted


    This IP:


    FE80:0ED1:0098:000A:0000:0000:0AED


    Can be expressed like this:


    FE80:ED1:98:A::AED

    IPv6 Loopback address
    ::0



    48:00 Getting an address


    Computer sends an icmpv6 packet called a Router Solicitation
    The router responds with its information (with its Link Local address)
    Either the router generates an ipv6 based on the requesting computers MAC address OR the computer chooses its own IP address
    The computer sends a Neighbor Solicitation packet which is basically the computer attempting to ping a device on the network with its IP address to see if its chosen IP already exists



    IPv6 you are on the internet by default unlike IPv4 in most setups

    "Host" bits are based on your MAC address, which can be used for finger printing/tracking



    Addressing

    Address broken into hextets

Music+Connoisseur ,

Great show, call in tech support eh

Love the show, topics, and Noah’s enthusiasm but my biggest gripe is the call in tech support calls. I mean it’s nice to have a tech support help line but I feel it really detracts from the show. It tends to interrupt the topics at hand and cuts the show short since it’s restricted to one hour because it’s a live radio show.

I’d love a Ask Noah Show Offline Edition where we can delve into the topics at hand.

JayFire-pop-Yo-Tire ,

Amazing

I'm a Fedex Express driver in Grand Forks and stumbled across this show on the radio one night recently driving home.. Just a month ago I purchased a System 76 laptop after getting fed up with windows so this show immediately sparked my interest when I heard it on the radio. I went home that night and looked to see if Ask Noah had a podcast and Bam! Here it is! I went back and downloaded the first 3 episodes and I'm playing catch up but my first thoughts is "Wow! This is good!".

I love Noah's enthusiasm and his passion for Linux and he appears to have a vast amount of knowledge he is taking the time to share with whoever wants to hear, that in itself is pretty awesome!!

I'm going to keep downloading the old podcasts and until I'm current but so far what I'm hearing..I'm loving it!

Keep up the great work Noah along with everyone behind the scenes pitching in to make this happen.

Erich1527 ,

Passion is Addictive

Noah loves what he does. You only have to listen to 2 minutes of his show to see that. It makes me that much more eager to pursue my IT career.
