Re: OpenVPN client auth-user-pass not working

Why don’t you strip the password from the key file? (With an OpenSSL command)
Doesn’t make any difference, security-wise.

Re: Raspbios and WiFi Access Point

The colloquial name is Raspios (raspi-O.S.) not something-BIOS. Bios is a PC thing, not applicable here. The first link makes no sense at all. The author configures both wpa_supplicant and hostapd and apparently expects them to work both at the same time on the same interface. I suggest you follow t...

No. I never felt the need to use debug.

Re: System updates, no space available on micro sd card

Try the Raspberry Pi Imager program, that will install raspbian (now raspios), not noobs.

If that fails check that SD card of yours, or try using another one.

Re: Fallback to alternate Wifi network ?

Again. You won't find the answers to your setup problems with a current copy of raspios in a 4 year old thread. AFAIK Wifi is soft blocked on raspios for every 5GHz-capable Pis. 2.4GHz-only Pis are not soft-blocked out of the box. To unblock wifi use raspi-config and define the wifi country of your ...

Re: Working with Overlay File System

Can't you mount rw a partition or bind-mount a directory from the underlay? I don't think writing directly to the underlay causes any sort of problem, I could be wrong but I did that often (not or raspios) and never had a problem. Disabling-enabling the rootfs overlay wholesale is not an option due ...

Re: Cron to shutoff wlan0 @reboot.

Which OS is that?

Don't use sudo in a crontab. Sudo is an interactive command.

On raspios a better way would be to configure /etc/dhcpcd.conf to enable/disable processing of network interfaces. E.g. "denyinterfaces wlan0" at the beginning of that file.

Re: Starting a docker container in Pi4 make IO too slow.

In my experience Docker runs perfectly well on Pi3b.
I haven’t used it much on Raspios and neither on Pi 4 but I doubt that makes much a difference.

Once you’re installed docker engine and rebooted look at the network and firewall configuration on the Pi. If things go wrong/slow it’s likely there.

Re: Configure the RPi as a Local Network Access Point (wired and wireless)

Ah yes I was wrong, 2 MACs and 3IPs.
In dnsmasq you can set "log-dhcp" and you'll get details regarding lease negociation in /var/log/syslog
That device seems to request 2 addresses, no idea why. The "problem" (if it is one) is on the device side, not the server.

Re: Rasp Pi4 - Wifi not reachable from all my LAN devices

Curiously the MAC address on the Pi for 192.168.0.1 does not match the one PC report for that address. Download a copy of raspios, install and see if PCs ping the Pi 4 ok. If not, check your PCs and the router. If yes, verify your network setup on the octopi image. (The MAC address for 192.168.0.1 a...

Confirm your findings on a pristine copy of Raspbian OS.
Install it as per the documentation.
There are many software reasons for which the wifi interface could not be found.

Forget DNS, if DHCP is not working something is wrong with the fabric of your network.

No, you have to use an openvpn client to test. Otherwise TLS fails very early. There is a management console in openvpn that apparently accepts telnet. Never used that. If your router uses upnp I think that thing has a tendency to shuffle port numbers and play with the source IP address and that bre...

Re: Access Point Routed - Issue with MASQUERADE and question about documented procedure

Your firewall was/is not in the standard configuration.
Standard configuration in raspios is policy ACCEPT on filtering, which would make your additions redundant.

If your system includes filtering rules already you need to adapt the guide to your situation.
