  1. Looking for board for nas

    Excellent. Look forward to your results. Stay safe, please don't disappear from the Banana 2k2 resistor curse
  2. Looking for board for nas

    Here you go: https://github.com/armbian/build/issues/511#issuecomment-258647387 The option to change mode on the R1 appears to be pretty sensibly exported. A simple resistor soldering. Really? The much hyped Espressobin also boots up with all ports bridged? I hope Globalscale have made it as easy as Lamobo to physically change this setting
  3. Looking for board for nas

    Actually these could be excellent daughter boards for the NanoPi Duo or Core. C'mon Friendly Elec!
  4. Looking for board for nas

    Good points tkaiser. I didn't get the board (it was overpriced by a factor of at least two for me, I don't need Wi-Fi, crappy 'SATA' or many of the other confusing bells and whistles - just give me a VLAN capable switch under the control of a reasonably powerful CPU which I will turn into a router). However, the ports isolated/bridged boot state is simply a pin property of the the BCM switch and is in the datasheet. I see no reason why it wouldn't work and be secure: if you lost the CPU then there's nothing to change the initial (pin controlled) state. If you lost the switch then there's nothing to worry about Put it this way, I use the Ubiquiti Edgerouter X (MT7621 processor with a 5 port gigabit switch with a WAN port created through VLANs) in production with 100% confidence. I'm really hoping that someone (maybe Orange Pi, their R1 is a promising move) will introduce the boards I need: H5 + Broadcom DSA capable switch + 3 gigabit ethernet ports for $30 (the espressobin is OK but pretty power inefficient, the processor's relatively weedy if not using the whizz bang hardware offload) (insert weedy processor here) + swconfig capable switch + 3 gigabit ethernet ports for $20 (to act as a simple linux controlled VLAN capable switch)
  5. Yup, all you need to do is connect with the Wi-Fi, enable masquerading on the Wi-Fi interface, allow ipv4 forwarding, run dnsmasq to listen for DHCP requests from the bridge , and set up a simple firewall. Google Linux router and you'll be presented with hundreds of good guides
  6. Looking for board for nas

    That's not correct at all. Many purpose built routers (Edgerouter X, Mikrotik Hex Gr3) have the same design. The question is whether the switch is brought up in bridged or isolated mode before the appropriate VLANs can be established. The design mistake with the Lamobo R1 was to bring up the switch in the wrong mode, but it could be corrected by the addition of a resistor on the board. I'm actually looking forward to the R2 (hoping that BPi will learn from the R1).
  7. What do you mean "gateway"? Draw a diagram or explain more clearly what you're trying to achieve (ie different subnets on lan ports and wifi? which will be your wan port?)
  8. Espressobin support development efforts

    Ha, hadn't thought of it like that. The use of that 1Gb interconnector between the Armada 37xx and the Topaz switch rather than the 2.5Gb line negates one of the main benefits of those comms specific chips over an Allwinner/Broadcom alternative And given that I want to almost always perform Codel/Cake over a saturated link then what use is the fancy hardware NAT acceleration offload? I haven't as yet seen any QoS benchmarks with quad-core A53 chips. If the dual-core 880MHz mips in an ER-X can push 120Mbps then surely we'd get much more puff from a modest H5. If you want to get really fancy you could use an RK3288 and turn its usb3 into a symmetrical 2.5Gb lane to the switch. Now how do we get someone to make these boards Good question about the limitation. I would say yes, unless there is hardware capability on that Topaz for the layer 3 features you want. I guess that if the switch handles all the intra-VLAN stuff at line-rate then you'll have that limitation applied to only the layer-3 stuff? Don't know, need to get my hands on some of this stuff.
  9. Espressobin support development efforts

    In essence what I'm waiting for is a board that uses a Marvell or Broadcom switchdev compatible switch chip, 2-4 gigabit ports and a cheap Allwinner SOC. In fact, the Banana Pi R1 was close, but it had an insane boot up mode for the switch (all ports switchable) and was overpriced by a factor of 3. I don't want on board Wi-Fi, SATA or any other of that BS. This should be possible for $20
  10. Espressobin support development efforts

    Yup indeed. So one way to think about it is like follows. The switch chips found in commodity wireless routers are often the very same that are in expensive managed routers, however the stock firmware provided gives no way to manipulate the powerful features possible on these chips. Openwrt uses a process called swconfig to configure the switch chips in these routers to support VLAN tagging. However, it only exposes the switch as a single network interface so that means that many things are impossible, such as per port/per vlan stats and STP (used to prevent loops from disabling large parts of your network). This is still immensely powerful. A £20 openwrt capable wireless router board from Aliexpress can be made to act as a gigabit managed switch running Linux. The possibilities that just VLAN tagging controlled by Linux provides are amazing! Switchdev/DSA go one step further for compatible switch chips. They expose each port to the OS. Therefore they take advantage of the ability of the switch to perform hardware intra-VLAN routing, but also allow the rest of the system to get involved with inter-VLAN routing/STP/IGMP snooping and other higher level functions, including the use of the hardware accelerators as found in Marvell/Broadcom/Cavium/Mediatek SOCs.This would allow Linux-based switches to be as performant as the proprietary mnged switches from Cisco etc.
  11. Espressobin support development efforts

    Network manager's so frustratingly limited, it always pushes me back to using /etc/network/interfaces, especially when I'm using VLANs and doing any kind of complex routing/masquerading. I'm really interested in these devices coming along with hardware gigabit switch chips (especially the Marvell and Broadcom BCM5XXX chips that can be configured using the Switchdev/DSA process), has anyone experimented with STP on the espressobin?
  12. Those emulators don't have access to low level stuff. They use the capabilities that iOS grants them. I think it's probably worth learning more about sandboxing and virtualisation
  13. missing u-boot repo

    Ah great, this explains why I've not been able to build a Pine64 image.
  14. What are you using your Orange Pi Zero for?

    As a wireless bridge for a USB LTE modem
  15. Pine64 mainline status

    What's the current status of 5.30 on Pine64 mainline? I've a spare Pine64 lying around and was considering compiling latest Armbian for it to poke around a little, test things if that's useful to the dev effort. The downloads page lists support as experimental, but the version there is 5.27 and some of the info seems out of date, ie points to the wrong subforum, etc.
