Re: USB Hub with Raspberry Pi 3 B+ and Raspberry Pi 4

On the 3B that is a hardware limit, I don't know the details but it's been discussed in the forum.

No idea about the authentication issue with 4B but it's good news if it can show all devices.

Mhh. Perhaps Spice (XSpice) could help?

Re: Raspbian Stretch as DHCP server

If you have configured anything in /etc/network/interfaces without deactivating dhcpcd, networking will fail. Do not configure anything in the interfaces file, and prefer configuring via dhcpcd.conf If you have option "bind-interfaces" in /etc/dnsmasq.conf, systemd will fail to launch the service. R...

Re: Problems with Bridge

Your bridge has 2 IP addresses, it's not that it's bad in itself but it messed up routing. 3: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 ... inet 192.168.10.100/24 brd 192.168.10.255 scope global br0 ... inet 192.168.188.41/24 brd 192.168.188.255 s...

Re: Problems with Bridge

Yes, your design is sound, it should work. Something is wrong somewhere, it's a matter of finding that.

Does the Pi itself get an IP address? Does it have LAN/internet access?
(post the results of "ip address show" 'ip route show" "ip -d link show" if you want.)

Re: Will 12w Apple iPad charger work with Pi 3B plus?

FYI, with the appropriate cable (not USB C) that charger will work to power a Pi 3B (not plus). It might be ok for a 3B+. However the official PSU has the advantage of featuring a non-detachable, rather long USB lead. With the iPad charger I've had the USB cable detach from the charger side by accid...

Re: Stability issues with Raspberry pi 4/2 GB and Raspian Buster

No relation.

iSCSI is very unforgiving of network issues. (So wifi is not an option.)
Make sure your network is perfectly clean, shows fast and consistent performance otherwise chaos will soon ensue.

Re: HDD turn off after trying to boot from it

Yes that looks like a power issue. There is a limit to the amount of current the Pi will provide to its USB ports, it looks probable the HDD needs more than that when it starts spinning. You could try with another laptop-type external drive specifically designed to power over USB, or power the HDD s...

Re: Problems with Bridge

You can try using this document.
It gives a DHCP address to the bridge in the Pi, from the main router.
If you want a static address, add an "interface br0" block in dhcpcd.conf with the static IP you need.

Re: raspbian and docker

manual macvlan creation + networking=none + pipework will work with DHCP. To assign IPs from the network you need the IP parameters but also to have some authority on it. Otherwise one day you might assign an address that is reserved to some special use, and the firewall will block or an alarm will ...

Re: raspbian and docker

The standard Docker solution is a bridge with routing/NAT, that works everywhere. If you nuke the bridge definition in /etc/docker/daemon.json, next time the machine boots Docker automatically creates its default bridge and chooses an IP range that does not clash with the host's LAN. If you keep the...

Re: my pi system time automatically goes to future DateTime, why?

The only reason I can see this would happen is if: - The DHCP server (in your router) sends the address of an NTP server - That NTP server is off by years (...) - Since Internet (with correct NTP servers) is unreachable, the only available server is trusted, and the date is off on the client.

There is p2p mode where the actual DHCP server is used. Configurations are simpler and if you get an address, it means the tunnel is really up. You’re using the default port 1194.
