Re: wifi + ap problem

Use of /etc/network/interfaces is deprecated and makes networking fail. Used dhcpcd.conf only on Raspbian.
See the official docs for network configuration.

43455 apsta?

Does someone know on good authority if WiFi “APSTA” mode is usable on pi4?
With the AP bridged?
Any kernel/application version requirements?

Thanks in advance.

Re: 5G wifi not working on raspberry pi 4

Generally speaking 5G WiFi goes faster but has less range than 2.4. It doesn’t go through opaque obstacles as well as 2.4.
If signal strength on 5GHz is poor, you could get disconnects.

Re: buster10 32 bit-external 120g SSD won't mount

Is that at boot or even trying to mount by hand once the Pi is up and running?

Perhaps that drive needs too much power, check its specs.
Or it doesn’t go well with the SATA bridge on Linux. You can try googling for the model of drive and chipset/driver used by the bridge.

Re: Raspberry Pi 3b v1.2 when connected to WiFi it nearly "kills" the network

Are you using static IP addresses? Maybe there is a conflict. Quite likely. 3B operates over the 2.4 GHz frequency band only, not 5GHz as other machines might. Normally 5GHz capable clients will not be switched to 2.4 unless the router is a (cheap) dual band, single radio design. If clients are swit...

Re: Raspberry pi with dhcp on both interfaces

Sounds like a bridge setup, not a router. https://www.raspberrypi.org/documentation/configuration/wireless/ has a bridged config how-to that would fit, I think.

And what are you trying to do with that interface?
Use it as a client (STA) or as an AP?

USB is “great” but if not driven at the right cadence and isolated you’ll get clicks and hum. Pi I2S + analog out works great anywhere anytime. HDMI I ...

Re: JSON proxy?

Avahi by default publishes a hostname record, ping foo.local works through that. All addresses should be listed below the record.
In addtition DNS-sd (unfortunately often pronounced "avahi" on linux) can be used to publish/retrieve arbitrary TXT records.

Re: RPi routing even if ip_forwad=0

It is not routing. You won't be able to reach machines downstream the Pi. But by default Linux will respond to pings and ARPs via any interface on behalf of any interface. The IP and MAC addresses are seen as attributes of the host. That is the weak network host model, which makes connectivity easie...

An automounter looks after paths you've configured. It creates an empty path, traps any attempt to access the path and mounts the target resource (device, server share...) on the fly if needed. Once nothing uses the path for a while, it dismounts the resource. The original purpose was mounting NFS s...

Solution 1: Use the automounter and let the firmware in the drives do their job when the drives are unmounted and idle for a while.
Solution 2: fliddling with hdparm, sdparm, ext4 settings, etc.

Key as in authentication through certificate+private key pair.
Actually there is an option for that in openvpn, no need to alter the key.

Re: Rebuilt busybox, no login prompt

Time to diff your makefiles, I think.
One last thing though. If your OS is using the init system provided by busybox, see what /etc/inittab looks like. Maybe it needs some help.
