If using the windows based bitcoin-qt, where do I change that setting?
I assume its in a txt file but none that I can find that mention setting/setup/etc?
There is no setting in the program itsself.
1. open windows explorer
2. type "%appdata%\bitcoin\" in address bar
3. create new text file named "bitcoin.conf". make sure file extensions are enabled so ".conf" extension is saved.
4. in the text file, put in "listen=0"
5. restart bitcoin-qt.
