IP

I have created a physical Ip of 10.10.10.10 on my lan0 and createda virtual ip of 10.10.10.11 on top of my physical IP. My application is communicating thru 10.10.10.11 but replying thru 10.10.10.10. Is there any way to force the reply to use the 10.10.10.11 instead of 10.10.10.10?

It's possibly related to the order that the /etc/hosts is configured in.

Make sure that 10.10.10.11 appears before 10.10.10.10

this is just a guess really, I've not worked on VIPs, but have come across a similiar type of pb with a different applications ha solution..

Try adding an alias in /etc/hosts such as
app 10.10.10.11
app 10.10.10.10

and trying again..
If that doesn't work, I have no idea..

Later,

Given that an IP is available on the system, the IP an application uses to communicate is dependent on the flags the application developer passes to the bind command in the application.

If the application binds with the INADDR_ANY constant (generally the case for older apps), the application will listen on any IP available, but will only speak on the base IP of the system.

If the application actually binds to a specified address (generally the case for newer Internet apps like web servers), the application will actually speak on the IP(s) you specified in the configuration of the application.

See the bind system call for more information.
