I am on Linux Debian 8.4 and have one server running 24/7.
I would like to help the Bitcoin network.

On https://bitcoin.org/en/full-node#other-linux-distributions I got to the point where I should run bitcoind and it should give me unique password:

Then you can run the command bitcoind. It will print output similar to this:

But it does not print out anything. Ideas?

Since Bitcoin Core 0.12, an RPC password is no longer required for normal operation. Instead, a random password is automatically generated by bitcoind and stored in a temporary file on disk. When an RPC client (like bitcoin-cli) wants to connect, it automatically uses the password from this file.

  • Remember to specify the -datadir on the bitcoin-cli command line if it isn't the default. Otherwise the cookie file won't be found.

If you already have a bitcoin.conf file in place it will not generate a password, backup your current config file and try again.
