I am working on a program that communicates with a server, however it doesn't resolve the address of the server so i can't use the host file to make it redirect to my local computer.

It is using a ip address, so i am wondering if there is a way to redirect a ip address in windows the same way you can redirect dns information with the host file.

Thanks.

Howdy,

Without knowing all the details, if it requires access to the server for verification, you will have to do a lot of work to make it functional.

Sorry to bother, the server simply sends a reply to the program with a verification string, so i built a emulator that listens on the required port and i am sure it would work.

However the problem is i can't force the ip address that the application is looking for, to redirect to my localhost, if the program was simply getting the dns from a host i could modify the hosts file, but it doesn't.

Also i would like to stay away from actually modifying the server ip inside the program if at all possible, so i was looking for a way to make windows whenever it gets a request to visit ip 1.1.1.1 instead go to 2.2.2.2 etc.

Thanks.

Sorry for the double post, also could you delete that account ?

I couldn't remember the email address i used for this account, but i got it back now, sorry!

Google 'ip routing'

Set a breakpoint on wsock32!bind(...), check to see where it's being called from and what IP address it's using, then patch the IP address.

WSAConnect i think is the one, or sendto, bind afaik (correct me if wrong plz) is only used locally for incoming data

Oops... I meant wsock32!connect(...). You'll want the sin_addr.s_addr field of the second argument.

Yes, in fewer (and more generic) words, hook WSAConnect (with your favorite API hooking technique) and change that IP-address on the fly.

Or just check your router documentation. Many (even the cheap ones) offer IP redirection.

Actually, even *Windows* itself has a built-in IP routing capability...

At a push, I bet you could assign the IP of the server to your local machine (as an additional IP) and that would fool it too...

*EDIT*
Assigning the ip address worked great such a simple way to do it, thanks a million!

Sorry for the late reply, however thanks a lot i appreciate the suggestions.

I did google ip routing first of all, but most of the topics were something i couldn't wrap my self around, i found route.exe and i will be trying that and the rest of the suggestions here (router, assigning the ip)

If that fails i know i can definitely patch it, i just wanted to stay away from it.

Thanks a lot.
