The pruned raspberry pi 2B experiment is a success!
I have transfered the .bitcoin folder from my laptop to my Raspberry Pi 2 B and after setting on bitcoin.conf the maxmempool parameter to 150 (just in case) , it started and its working.
I would like to know why it is still down in the website bitnodes.21.co
I have run the open port checker and its OK but in the statistics it appears offline
Can somebody explain?
Do you have to register it with them?
Also, just as a point, maybe they don't think it's powerful enough to receive a status update every few minutes and be able to transmit that without taking up a substantial amount of its resources.
It's great to hear you got it working! Also, if you store any bitcoin on your computer and copied over the wallet.dat, you might want to move those coins or delete the file from your raspberry pi - to make your keys a bit more secure.
You just have to go to bitnodes21.co and check if your current node has incoming open ports. They you can search by your node public IP and subscribe to receive alert about such node.
The Raspberry Pi 2B has 24 hours up and it is working 100%, I would like to highlight that it is also hosting my OpenBazaar store to keep it online always.
I dont store any coins in the Raspberry Pi 2B , I have compiled a walletless bitcoin core so no problem with that, thank you for the advice.
