When started with -v flag, Alfis tries to initialize the DNS port listening

It looks like when started with -v flag, it tries to initialize the DNS port listening. If another instance of Alfis is already running at this time, the "Failed to bind TCP (UDP) listener" error will occur.

Here no problem. How can you start few services on one port at same time?

I think when running with the flag to display the version just don't need to initialize the DNS listener.

Just run with the -h flag and read the help, ok?

Ups! I'm sorry!
