- in the log.txt net-downup.sh is a script for ifdown & ifup, run by user fadmin.
Is it run manually? Or is it run automatically by systemd?

- The desktop session that I use to trigger hibernate (LXDE desktop menu), and attempt to use the network connection with, is an user without group adm, but has groups netdev.
Is it a your custom configuration ?

- I noticed the firewall does block connections at 2024-02-26T17:33:04.983212+02:00 after hibernation, over 30s before the fadmin user runs ifdown & ifup - implication: maybe connection problem is something related to the login session + user groups and their relation to DHCP.
Again, is it a your custom configuration ?

- On the system, there is an admin fadmin with group adm, that I use to run the net-downup, and apt update for extra fun move.
Code: Select all
$ groups
fadmin adm dialout fax cdrom floppy tape sudo audio dip video plugdev netdev bluetooth scanner lpadmin gamer
- the desktop session user is gamer
Code: Select all
$ groups
gamer cdrom floppy audio video plugdev games netdev
Some questions:
1) Is the root account disabled or is it still enabled ?
2) Have you tried temporarily disabling the firewall to see if the network adapter is pulled up after resuming ?
3) How do you configure the firewall ?
4) Do you really need the modemmanager package (it generates useless warnings in the logs) ? if not, you can remove/purge it
5) What is the output of the command (it should not be installed):
6) What is the output of the following command ?
7) create a file named /etc/udev/rules.d/00-debug-net.rules (as shown below); then, reboot the system and hibernate; the system log should contain some lines about network configuration by udev before and after hibernation:
Code: Select all
# /etc/udev/rules.d/00-debug-net.rules
SUBSYSTEM=="net", OPTIONS="log_level=debug"
8) Can you supply a full system log to verify calls and returns to systemd services and called services after 7) ?
