strange eth* devices related messages appear/are logged > why? > fix?

[rcocchiararo]

I finally made the problems i explan here:

http://www.linuxhomenetworking.com/f...ad.php?t=19296

go away (dunno really how, this time the pppoeconf internet connection didnt stop working after reboot).

now i have a "problem", if im not using a GUI, i noticed there were WIERD messages flooding my screen, messages that are logged in 2 diferent files, and im attaching both as examples (with just a few messages, both files were 16++ mb in size, and rapidly growing)

the more ETH* interfaces i have enabled, the more messages appear, and more frequently.

Any idea why i get those ? how to fix the reason for they to appear, or at least, to prevent them from appearing ?

thx

It looks like you have some sort of bridge setup between eth1 and eth0... are you aware of this or is an application doing it?

[rcocchiararo]

i have a bridge between eth0, eth1, eth2 and eth4

i "discovered" that my "problem" was using ipmasq (no idea why it was mentioned as needed), and it was setting its own iptables rules, leaving me with logging and stuff.
