Instead of using makeseeds.py
this way:
0python3 makeseeds.py -a asmap-filled.dat < seeds_main.txt > nodes_main.txt
We could use the DNS seeds file as an argument since it is a required one. It improves the way the script handles it when that file is missing as well as makes this script more friendly. E.g:
0python3 makeseeds.py -a asmap-filled.dat -s seeds_main.txt > nodes_main.txt
