FYI,

For all you e100-1.6.X users out there.

I just found if I turn off hardware checksums, ie:
/sbin/modprobe e100 XsumRX=0,0

LVS works with the latest intel e100 drivers.

Now we just need to figure out why LVS doesn't work with Intel's hardware
checksumming.

------------------------------------------------------------------------
All,

After working with Julian and Joseph I found it was my NIC driver causing
the problems.

My director has 2 Intel eepro100 nic cards.  I wasn't using the default
ee100pro driver that came with kernel 2.4.7, instead I was using the latest
(at the time I downloaded it) driver from intel for that NIC, e100-1.6.6 due
to an earlier bug in the eepro100 driver causing unrelated NFS problems.

After going back to the default eepro100 driver, my problem went away.

I just tried upgrading to Intel's now latest e100 driver (e100-1.6.13) to no
avail.  Looks like I'm stuck using the default eepro100 driver suppied with
the kernel to make LVS on 2.4.7 work.

This problem is for both LVS-0.8.1 and LVS-0.9.3.

        Hello,

BTW, what show these commands on the director:

ip route get from 216.163.120.2 to 10.75.0.2 iif eth0
ip route get to 216.163.120.2 from 10.75.0.2 iif eth1

And I assume that ping to 10.75.0.2 from the client host does not work.
