I am running a bitcoin rpc server on my raspi and I can connect to it using local bitcoin-cli, but not externally from a windows on the same LAN. I tried installing ufw and disabling firewall on my raspi, and allowed tcp and udp connection to remote port 8332 on my windows, but that didn´t work. I can ping my raspi´s api from windows, but I can only get response from pinging my windows from raspi if I disable windows´ firewall. I don´t know what else to do.

I just noticed that if I put -rpcconnect=192.168.0.114 on bitcoin-cli argument it doesn´t connect, but if I put 127.0.0.1 it connects, and I am certain of the raspi´s ip is 192.168.0.114 from ifconfig result and also from ssh connection ( which works )

  • I know how to setup http/ftp/nas servers, but now I want to set up bitcoin servers for two reasons: (1) My bad friends will LOL at me if I don't have a money making" server/machine. (2) Learn more block chain things (I know nothing about it) to survive, since IPlv6 and 5G are coming. Question: I have 4 Rpi4Bs in my home network. Do I need to TCP/UDP break the fire wall to meet other money making guys? en.bitcoin.it/wiki/API_reference_(JSON-RPC) – tlfong01 Sep 28 '19 at 4:29
  • hey @tlfong01 I just found out the issue, check my answer! – Badjano Sep 28 '19 at 5:14

I just found out that I need these lines on bitcoin.conf to access rpc from outside localhost:

rpcbind=192.168.0.114

rpcallowip=0.0.0.0/0

or start bitcoind or bitcoin-qt with -rcpbind=xxx and -rpcallowip=xxx

Apparently if you don´t bind your ip to your lan ip, it will only work with local connections, and rpcallowip=0.0.0.0/0 is not recommended because it opens up for anyone to connect, so I´ll probably change that but if you don´t, make sure your password is secure enough.

  • Hi @Badjano, Nice to know you solved your problem. I will remember your warnings by heart, even though I don't understand, what do you mean by binding "global IP“ to "local ip" etc. You seem to have a way to get a static IP, which I have recently given up, because I found out static IP is expensive. I know very little about networking, bridge, access point, etc. So I am googling and wiking to read more. I am also studying python tcp and udp modules, so to dig a tunnel to jail break firewall outside, to meet other blocking chain money making gangs. – tlfong01 Sep 28 '19 at 5:25
  • the ip I had to bind was my local ip on my private network, not a global ip ( which would be the one on my router ). I could forward the local port on to a global port through my router, but I don´t want to do that. There are 3 levels of access here, a localhost, which is only visible on the same computer, a private network level, which other computers on your network can see, and a global network, which is visibible from anyone in the internet. I wanted to be visible on my private network only. – Badjano Sep 28 '19 at 5:42
  • What are these lines mean? Where they are located? Please don't answer in a comment. Instead edit your answer and put it there. – Ingo Sep 28 '19 at 9:07
  • @Ingo see if that helps! – Badjano Sep 29 '19 at 1:00
