  • No, that’s handled by ARP requests. In this case, it’s likely that the DHCP server is on the gateway, as that’s a pretty common setup for home ISP router arrangements.

    Gateway refers to a router that has access to other networks. In this case, the default gateway, which will be the router that has access to the internet.

    DNS or name servers are a separate option in DHCP leases, as are the IP addresses for DHCP servers, which are more of a windows thing generally.

    In this case this comment is probably an accurate description of what’s happened:

  • I’d hesitate to call it truly enterprise, but I’ve used the 24 port/10Gbe version of these in a datacenter. Not many issues to write home about - seems to handle vlanning pretty well.

    Has 10Gbe uplinks, US power, and PoE+. Probably access to a fancy dashboard too.

    $1600 is probably as cheap as you’re getting.

    Edit: Oh yeah, they’re probably not dual attached, and the ‘redundant power supply’ (RPS) is a separate appliance, which I consider kinda bullshit, that takes up another U.

    I’ve had no trouble with actual switching performance though fwiw.

    Edit 2: They’re probably compatible with the AR mobile app, which is hella cool, and somewhat useful in customer sites.

  • I would not consider Mermaid complete enough for network diagramming. The very basics are possible, but try to describe anything more complicated throws off the placement and makes the pathing whacky.

    Straight flow charts are the closest you can get to a network diagram, so if you try to draw a link that travels back up the chart, it breaks mermaid’s brain trying to figure out the order of decision points (network devices).

    The allure of text based diagrams is so tantalizing - but if you need them to be functional, it’s not going to happen

    There’s an issue tracking the need a new diagram type to handle it.


  • If the files exist, are regular, are correct and the permissions don’t prohibit access, maybe there’s something else blocking the connection attempt.

    Given that it’s ubuntu, could it be an AppArmor thing? Not sure if that’s enabled by default these days.

    Seems to me like it can’t run the binaries, so there’s nothing listening on the sockets you’ve specified. Fix the bin-path issue, fix the problem




  • There’s been some nasty buggery with avahi instances on containers clashing with host ones in the past

    Some programs just don’t like to run without access to parts to your system like /proc /sys and /run.

    Rather than bother with crafting bespoke permissions, non-default cgroups and elevated rights for certain containers, I’ve definitely opted for just installing a VM.

    It was always a time/functionality choice, and not one I make often - crafting the right solution is always better; but I have done it
