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.
Question: has anyone else been able to get ssh working to LVS (ipvsadm-1.21-9.ipvs108)
on kernel 2.4.21-20.ELsmp?
Only clue to ssh not working is the following error message reported in the /var/log/messages
of the realservers:

Jan 19 19:45:40 minos08 sshd[4558]: *Did not receive identification string from 131.225.110.58* < This is RIP of the
director, not VIP>

At this point, I am thinking that the ipvsadm version is not the best one for using with ssh. Anyone already encounter a problem like this? Anyone have any ideas or suggestions on
which way to go from here.

any and all suggestions welcome,
