How to run mulitple instances of app, each for unique IP?

maxxjr · Post by **maxxjr** » Wed Jul 29, 2009 1:10 pm

I have a windows application that can listens on an IP address for batch data to process. The application works under WINE. The application does not take advantage of multiple cores of the CPU. I want to configure the Linux PC to listen on four IP addresses (which I know how to do), and then run an instance of the wine app for each IP address. In this way, I can take full advantage of a quad-core CPU.

Does anyone have suggestions/pointers on how to proceed?

Thanks!

Wouldn't this be a question for the application's support and not
wine? I mean usually an application will have some configuration on
what ip address it listens to not the os controlling what ip address.

Use separate WINEPREFIX's.

When I start the application up under wine, it pulls the IP address it listens on automatically from somewhere. When I first tried it, it pulled up a 127.1.0.1 type address, since this is what was in my /etc/hosts file for my hostname. Which I changed the hosts file so that the hostname was associated with the network IP 192.168.1.x, the application pulled this new IP address up.

Hi Austin,

I did a quick read on WINEPREFIX's, and I don't think this will do it. As far as the application goes, it will look like it is running on different PCs. But when it goes to pull the IP address from the host, I think I need something else to tell it to use eth1 vs. eth0, as an example. Otherwise, all instances will pull the default eth0 address.

The WINEPREFIX is probably very necessary to keep each instance of the app from overwriting work data, etc. of other instances, so I think this does get me past an issue I had not realized was coming, yet.

Thanks!

So there is no way to set this in the application. You may want to
check to see if it creates a registry entry. Once you get that solved
use Austin's advice about prefixes.
