I looked through four available free software XMPP servers, and every uses some special implementation of DNS query. None of them relies on standard C functions, that proxychains hooks.

In udns, it implements dns client with, obviously with low-level funcitons like socket(), sendto(), etc. Is it possible to hook that functions? So that I can use this 3rd party dns client with proxychains.
