I can't see what is wrong with your configurations. But since your bitcoin.conf is on your home folder, i would try to copy the bitcoin.conf to
/mnt/bitcoin/bitcoin.conf, and then run
bitcoind -conf=/mnt/bitcoin/bitcoin.conf
After it running, try to check it again.
vv181,
Thank you very much for the suggestion.
It works.
I ran this command and it is a success in getting IPv4 and IPv6 flags set to false:
bitcoind -daemon -conf=/mnt/bitcoin/bitcoin.conf
AdolfinWolf,
Your suggestion seems good to use for future problems.
I shall remember it.
Thank you very much.
For those who are new to this. Check out the references I listed in my first post to get started.
If I can do it , you can do it.
