This is a DNS proxy server, made with pain and a bit of c.
Main idea: accept connections, read queries, if domain name in blacklist queried - return refused, otherwise ask top server (on code and config named as boss server) and return what it responds.
libevent-dev needed for building, also this code is not supported on windows. After cloning , in cloned directory command "gcc -Wall main.c -L. -levent -lm -levent_core -lpthread -levent_pthreads -O3 -o oh_no" can be used to create executable file and command "./oh_no" to execute that file.
With start of program you can query this dns server, for example by command "dig @127.0.0.1 -p 53 google.com"
When the program starts, it will also recognize config, such as top server and blacklist, which can be changed if it happens as in the example.
