I have created a (needlessly complicated) networking setup that I tried to create by following this guide.
I have colosally screwed up and now my RPi will disconnect randomly and requires a reboot to fix - even when plugged in via Ethernet. This issue seems to occur randomly and is very rare (I've seen it 5-6 times in two weeks)
Because my Pi 3B+ is running headless (dietpi, no HDMI), the only ways I can communicate with it are:
- SSH over the LAN
I have successfully enabled UART, and can see kernel boot messages with
screen, but I can't see any logs related to networking.
I have enabled uart in the
/boot/config.txt, and my
/boot/cmdline.txt looks like this:
dwc_otg.lpm_enable=0 debug console=serial0,115200 root=PARTUUID=27504eef-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait noswap ro fastboot
But this only shows kernel boot logs. After the device boots up I cannot see anything else coming through
How can I see networking/ more verbose logs on my headless RPi while it is having networking issues?
