Hi,

I don’t know where to put this. I have this error message during boot-up for quite some time. It somehow started in January 2025 after an update and I did not pay attention because everything seems to work fine. Could not find anything in Google about this. Maybe someone can point me in the right direction what this is.

The “consider r2q change” messages are normal and common. It is suggesting some tweaks to the classes in question. The other message I haven’t seen before. Have you tried looking at line 18 in qos.sh for clues?

Hi,

thanks for this hint.

I am just a user of IPFire and not familiar with the system internals of IPFire. The line 18 is:

```auto
case "$1" in

```

The first lines of the script including line 18 read as follows:

```auto
#/bin/bash
#################################################
# This is an autocreated QoS-Script for #
# IPFIRE #
# Copyright by the IPFire Team (GPLv2) #
# www.ipfire.org #
#################################################

### SYSTEMVARIABLES:
# RED INTERFACE: red0
# IMQ DEVICE: imq0

eval $(/usr/local/bin/readhash /var/ipfire/main/settings)
if ["$RRDLOG" == ""]; then
	RRDLOG=/var/log/rrd
fi

case "$1" in

  status)
	case "$2" in

...

```

Something with the logs? No clue.

I don’t think it is line 18, but line 148 of qos.sh.  
There is the command referenced in the error message. My system doesn’t contain filters for parent ffff:.  
Maybe my init crashed also. To be investigated further.

Just saw that later in this script all individual rules for QoS are included. That means everyone has its own version of this script. Looking at line 148 it contains an IPTABLES rule in my script. That command is in line 216 in my script.
