I tried setting up two nodes on the same server, using two different usernames. So using terminal, I logged into the different users and try to connect to eachother.
I issued different port numbers for port and rpcport. Both nodes start, using different terminals/users.
On one user (initial user) the cli allows me to query through getinfo. The other gives an error:
error: incorrect rpcuser or rpcpassword (authorization failed)
The password of the rpcuser in ~/.multichain/chain1$ more multichain.conf is different for both users, which is ok?
Anyway. Just needed thumbs up if it is possible to use only server to test multiple nodes. Or is the IP address some sort of unique key?
(tried google on your site, but couldnt find the answer)
