How to connect multichain rpc?

Wed, 24 Jul 2019 05:24:47 +0000

Hi,

I have setup multichain in Oracle VM 6.0.4 using centos. i created a chain and in its config file I have put

rpcport = 9699

rpcconnect = 192.168.1.35 (centos ip)

rpcallowip = 192.168.1.79 (my mac ip)

listen =0

Then in my node app I installed "multichain-node" and try to establish a connection. But every time it responds with "ECONNREFUSED". What should I do to establish an rpc connection?

Unauthorized Error with multichain-node and ssh port forwarding

Mon, 22 May 2017 13:02:46 +0000

Hello,

I am using the multichain-node package to connect to a blockchain which is running on a remote server. For testing my code, I forwarded the remote port to a port on my machine, because the multichain is only accepting requests from localhost. Now I get an Unauthorized Error, and I don't know why. I also set up a rpcuser and rpcpassword in multichain.conf.

Here the connection object:

const connection = {
    port: 7194,
    host: '127.0.0.1',
    user: 'multichainrpc',
    pass: 'MyPass'
};

let multichain = require("multichain-node")(connection);

Do you have any ideas to fix my problem?

Regards,

Andreas K.
