Hello all,
I have a question concerning real servers.
We have a 2 director LVS that load balances for 2 squid boxes in
acceleration mode and a Windows 2000 box. We can send requests all day
long to the squid boxes and the respond flawlessly but we seem to be
unable to get the Windows box to respond to our requests.
I have added a Microsoft loopback adapter to the box and given that
adapter the corresponding VIP, which happens to be xx.xx.191.5, the x's
are there to protect the innocent. I have given it a Netmask of
255.0.0.0, which is in the how-to. This box does nothing but server
https: for a client's website.
In another part of the how-to it says to do a route delete <VIP's
Network> <VIP Mask>. We have tried to do this numerous times but
everytime it tells us "The specified route cannot be found".
Do any of you know of a good way to see if the packets are getting
through?
Or if by looking at the information I have provided see anything that
could or should be done different let me know.
Thanks for your help
AJ
