Use the Noarp module with RHES3.0 it solves all this messing about.

The only problem is RHES3.0 has a version.h which compiles for all 3 versions and The Noarp configure doesn't cope with this. To fix, edit out the #define UTS_RELEASE lines you are not using then configure and compile. We have been using it for years the RH7, 9, and ES3 and it works beautifully.

Hi all,

      I am not having any luck getting ssh service to run to LVS
running on LTS3.0,
kernel 2.4.21-20.ELsmp. Main problem seems to be in getting rid of arp
problems.
Odd thing is that after having used the "Horms method" to the
realservers, telnet
service to LVS works ok. I tried installing the suggested "hidden" patch
for this kernel to see if it would control the arp issues differently
enough to get ssh
service to work, but the patch will not install with this kernel.


If you can get telnet to work, then you should be able to get ssh to work.
That you can't indicates that your system is not working as you've described
it. Either you don't have the arp problem solved or the LVS isn't load balancing
telnet.
I know people with distributions want to keep using the kernels that come
with them, but for now try a plain vanilla kernel, which will accept the hidden
patch. If you really want to go back to your distribution's kernel then
you can do that after you have your LVS working.
