Re: stuck in wifi - Debian wheezy

Besides, this interfaces file is in shambles.
There should be valid examples in /usr/share/doc/ifupdown/examples on your system. Or search online for examples.

Re: I can't use sshfs after Raspberry changed to dhcp IP

Use the manual on your system to learn about the meaning of commands and options, e.g. "man ssh". In this instance I don't know why "-Y" works better for you. I assume your ssh client warns you the remote machine has changed IP address and asks for confirmation before connecting to this "unknown" ho...

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.

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...

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...

I think I read the readme and especially this and from there a version with DHCP in the container wasn't far.

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 ...
