OMLx 4.2 -- RPi4 -- How To Troubleshoot Internet Access Issue?

Tags: #<Tag:0x00007fb4561b89d0>

Hello,

  • **OpenMandriva Lx version: **
    Version 4.2 for Raspberry Pi 4

  • Desktop environment (KDE, LXQT…):
    KDE

I just installed Open Mandriva v4.2 aarch64 on my Raspberry pi 4B using Balena Etcher and GParted as the utilities for the write2fs utility were unavailable on my Debian Linux PC.

Wired Connection 1 shows activity but I am unable to ping any www hosts? Is there any information on the OMA Wiki that will allow me to research, troubleshoot and configure my internet connectivity?

Thanks

Hi.

  1. try to run ping 8.8.8.8
    if you got an answer it means that something wrong with dns
  2. try: tracepath 8.8.8.8

show here
ip a
ip r
cat /etc/resolv.conf

Hi fedya,
Thanks for the quick reply. Here’s some of the intial findings …

  1. ping to 8.8.8.8 returns a reply
  2. tracepath 8.8.8.8 results in a no reply after reaching ip addr: 74.40.26.254 at step 6:
  3. ip command is currently not found on my installation
  4. cat /etc/resolv.conf has the following non-comment lines:
    nameserver 127.0.0.53
    options edns0 trust-ad
    search home

try to run
/sbin/ip r
/sbin/ip a
or just ip a from superuser

show output of a ping 8.8.8.8 command

127.0.0.53 looks a little weird as a nameserver (127.x.x.x is for loopback…). Apparently systemd-resolved is messing up. Does everything work if you change “nameserver 127.0.0.53” to “nameserver 1.1.1.1” in /etc/resolv.conf?

Hi fedya,

Per your request; also included the tracepath 8.8.8.8 output …

bero’s suggestion to mod the resolv.conf nameserver to 1.1.1.1 did allow me to view the Open Mandriva and Yahoo! Home pages on the Falkon Web Browser.

Thank you both for your quick help.
