When I run this command 

bitcoind -testnet -printtoconsole -rpcuser=123456 -rpcpassword=123456

After bitcoind is up. I run this on the same Ubuntu 17.10

bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=123456 getbalance

I get this result: error: incorrect rpcuser or rpcpassword (authorization failed) The second day I tried exactly the same way. I get the correct result. It is really weird.

I try to put these two lines in /home/user/.bitcoin/bitcoin.conf

rpcuser=123456
rpcpassword=123456

And I run this command

bitcoind -testnet -printtoconsole -conf=/home/gogogo237/.bitcoin/bitcoin.conf

And this 

bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=1234564 getbalance

notice that I intentionally changed -rpcpassword to a wrong password. But I still can get a correct result. This is really unpredictable and obviously a mistake. Anyone can explain this error? Thanks!

  • interesting, but for sure not the default behavious. I am normally on OpenSuSE. I have self compiled and downloaded full clients. Please provide some more info: did you use bitcoin core from website? Self compiled? apt-get? Did you check download files (hash)? I think I have a fresh Ubuntu virtual machine, where I could try to install the one you where using...

  • Self compiled from the newest source code.

  • similiar discussion here, as bitcoin15 is not yet released: bitcointalk.org/index.php?topic=2172765.0. You downloaded from github.com/bitcoin/bitcoin?

  • just downloaded from github, and couldn't compile, cause autoconf throws already some errors. And for sure ./configure as well. Damn, wanting to help, and now need help myself ...

  • To avoid others doing same error (RTFM correctly, not in a rush): autogen.sh, not autoconf !! Now it's compiling. Update to follow.

Reset to default

re-compiled on an Ubuntu system, fresh from github.com:

$ uname -a
Linux ubuntu-ae 4.10.0-19-generic

$ bitcoind -version
Bitcoin Core Daemon version v0.15.99.0-g96ac26e5662

$ bitcoind -testnet -printtoconsole -rpcuser=123456 -rpcpassword=123456

$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=123456 getaccountaddress "myaccount"
n2r1aQiA37LLgy4qWjuLHXqA9ZhtcX4KG6

$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=123456 getbalance
0.00000000

and with wrong password:

$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=1234564 getbalance
error: incorrect rpcuser or rpcpassword (authorization failed)

so s.th. is wrong with the sources? Or with Ubuntu setup. What kernel do you have (uname -a) ?

In case you changed your /etc/systemd/system/bitcoind.service make sure you run

 sudo systemctl stop bitcoind
 sudo systemctl daemon-reload
 sudo systemctl start bitcoind

to apply the changes.

The error from the question could (and did in my case) arise because I did not use daemon-reload to load the new config.

  • While this advice may be useful, the question doesn't ask anything about systemd or with changing systemd service files.

  • The error from the question could (and did in my case) arise because I did not use daemon-reload to load the new config. Since this solved my problem - which was the same as OPs - I thought it would be a good thing to know.
