Description Stig Hackvan 2000-01-25 18:49:01 UTC
observed behavior:

"gateway"                   "middleman" <---- net0 ----> (eth0)                   "victim"
                         (eth1) <----- net1 ----->

if "victim" is moved from net1 to net0, then "middleman" still responds to
arps for (even _after_ 'ifconfig eth1 down') and so it's
impossible for "victim" to reach "gateway" because it's getting bogus arp


1. "middleman" is only on net1.
   it should _never_ respond to arps on net0.

   - "middleman" kernel: 2.2.14 + ide>32gb patches

2. 'ifconfig eth1 down' doesn't work properly.

   - "middleman" kernel: 2.2.14 + ide>32gb patches

   same behavior observed on "victim" 2.2.12-20 kernel

Comment 1 Stephen John Smoogen 2003-01-24 16:16:39 UTC
Does this network problem still occur in the latest 2.4.x kernels or the 2.2.22
kernels for Red Hat Linux 6.2. 

[PS I have not been able to duplicate this, but my home lab environment is not

Comment 2 Jay Turner 2003-04-14 18:01:36 UTC
Closing out due to bit-rot.

Comment 3 Stig Hackvan 2003-04-15 21:07:25 UTC
the original trouble report contained the wrong release info.  the behavior was
observed on a 7.3 system and i don't have the facilities to do further testing
on it.  i recommend trying again on 7.3 and then ditching the report if you
can't reproduce it.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
