Web server to shift between 2 NICs

[SwapSawe]

Hi !!!

A situation which has stumped me.

Scenario -

The web-server running with two NICs hence, two IP-address. Now the Webserver is listening on one IP.

Requirement -

The Web server should be intelligent enough to shift to another IP, in case the first NIC fails.


I do not know if this is correct form to present my case, but eitherways, I am sure the professionals around here might have been through this scenario at times in their times.

Any directions are welcome.

Thanks in advance,
SwapSawe.

ASFAIK, Java cannot manipulate OS & hardware level stuff like switching between IPs. You listen on whatever the default ethernet is, ie whatever 127.0.0.1 resolves to.

If you need failover like that, I would have two or more clustered machines rather than two IP addresses !

Thanks sedj, even if its not a solution, but atleast you informed me that I am looking in wrong direction for the solution.

I guess I should think about some thing like Load balancing techniques... however since I am looking for least expensive soln. I would be looking for a software for load-balancing hence. Thanks again.

Hello, I just now found that you can make webserver to listen on more than one IP Address in case you have multiple NIC, I don't know if I am understanding it correctly this link tells me that probably I have found a solution, ie. in case one NIC is down the other NIC would still be available to cater the clients. Am I thinking right?

Well thats the Apache HTTP server which is written in C, and is completely different to Tomcat which is written in Java.
