Please give me some idea about how we can query the DNS
How you have divided the passive dns functioning into two parts as recursor and resolver.
Can you please give some idea about how they function, and when they are employed after the query is submitted to the pdns
How the data packet will be analyzed for ddos attack.

DNS query against a specific server using python

socket.gethostbyname sends the DNS resolution query to the DNS server specified by the OS. Is there an easy way to send a query to a *different* server?

I see that twisted.names allows you to do this, but, having all of twisted as dependency to my project when all I need to do is a simple DNS query seems a bit extreme. I also found pydns, but that looks fairly outdated and unmaintained.

Reading log and saving data to DB using python script

I have a Ubuntu server running NGINX that logs data for me. I want to write a python script that reads my customized logs and after a little rearrangement save the new data into my DB (postgresql).

The process should run about every 5 minutes and i'm expecting large chunks of data on several 5 minute windows..

My plan for achieving this is to install python on the server, write a script and add it to cron.

My question is what the simplest way to do this? should I use any python frameworks?
For my python app I'm using Django, but on this server I just need to read a file, do some manipulation and save to DB.
