WARNING: failed to install socket filter

[Richard Mayhew]

Hi

Enable the "Socket Filtering" under Networking Options in your Kernel Settings.

And possibly "Network Device Emulation"


This should fix the problem.

         What kind of Network cards  you have ?

         I am experiencing the same problem and thinking about a driver 
problem.

         In a IBM Netfinity 3000  (etherexpress pro 10/100  onboard) and 
any others NIC inside, I see a strange problem.  I will explain....

         eth0  -  192.168.1.1
         eth1 - 192.168.1.2
         eth2 - 192.168.1.3

         If I remove the network cable from eth1 and eth2,   the machine 
remains responding to ping - for an unknown reason.... eth0 assumes the 
address of eth1 and eth2.

         if I remove the network cable from eth0, but connect the cable in 
eth1 or eth2,  the machine stops responding on the network.  All the 
addresses stop responding....

         The system is a RedHat 7.3  with Kernel 2.4.19 compiled from 
sources....

         Anybody have an Idea ?   Is that normal because all the ip address 
are in the same subnet ? Any idea of why the NICs  stop responding if I 
remove the cable of the onboard NIC ?

         thx
