-------- Forwarded Message -------- Subject: New tool intercepting and overriding libc DNS calls Date: Thu, 22 Feb 2024 12:33:03 +0000 From: Andriy Utkin <he...@autkin.net> To: c-ares@lists.haxx.se CC: Ben Greear <gree...@candelatech.com> Hi all, Under the direction and funding of Ben Greear of Candelatech, here is a new tool which is open source (MIT, same as c-ares) for the benefit of others. You LD_PRELOAD it to existing utilities, e.g. `ping`, and it changes the behaviour of getaddrinfo() so that you can control how the DNS queries happen: - which network interface is used, - which source IP address is used, - which DNS servers are used. There's not much complexity in the code as all these settings are in the established libcares API. The original use case is to support VRF https://en.wikipedia.org/wiki/Virtual_routing_and_forwarding Here it is: https://github.com/andrey-utkin/candelatech-vrf The intention is to share it, get feedback and improve it. Ideas for a name are also welcome :) Ben suggested to offer it as an addition to c-ares' src/tools/ directory, which I think is a great idea. Please let us know what you think. -- c-ares mailing list c-ares@lists.haxx.se https://lists.haxx.se/mailman/listinfo/c-ares
