  • MAC filter

    From John Conover@21:1/5 to All on Mon Sep 2 05:50:01 2024
    The MAC filter needs a local filter for the two 16 X dual hex, (23
    total,) digits.

    The MAC is router usually aligned internally by the router, and
    contains unique hex digits.

    Does any anyone recall how to query the digits to the display?

    Thanks,

    John

    $ ip -j link | jq '.[] | select(.address) | .ifname + ": " + .address'
    "lo: 00:00:00:00:00:00"

    And if you're interested in only the interface name and MAC address, pipe
    that result to awk, so...

    ip -br l | awk '{print $1,$3}'

    Cheers,
    Tom

    Usually displayed on the routers home web page. If not there, check the
    status pages. But you may have enter your user & pw to see that.

    Note that the $3 won't always be a MAC address:

    % ip --brief link
    lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
    [...]
    tun0 UNKNOWN <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP>

    Every reply I've seen talks about local macs.

    arp -a

    ipv4.firewall17.home.woodall.me.uk (192.168.100.1) at 00:16:3e:e0:70:01 [ether] on eth0

    if you're using ipv4

    Don't know a good way on ipv6, best I can think of is
    ping ff02::1

    64 bytes from fe80::216:3eff:fee0:7001%eth0: icmp_seq=3 ttl=64 time=2.15ms

    To be honest I had trouble parsing the original post as a cohesive
    English text. I mean it had words I understood, just not in that
    particular combination.

    ping ff02::1

    ip neighbor

    (is also the "new" way for IPv4)

    Thanks,

    That is *so* much more legible than the standard output it's a shame it
    wasn't the default. I've resisted internalising usage of `ip` under the
    vague hope that it will eventually be displaced by something friendlier
    to read by default, saving me the effort.

    Yes. I assumed the author wasn't an English soeaker.

    Nice. Thanks. And ip neighbour works too :-)
