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

    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

  2. #2
    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?
    63,000 bugs in the code, 63,000 bugs,
    ya get 1 whacked with a service pack,
    now there's 63,005 bugs in the code!!

  3. #3
    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.
