user13583: I'm trying to work with the bitcoin daemon and rpc.
Using the user & password I set I can't connect to it, trying with curl I always get "Empty reply from server".
It works just fine in the real network, I can connect, getinfo, etc, etc...
Is there something I might be missing? the output log in the daemon only shows:
accepted connection 190.xxx:62470
disconnecting node 190.xxx:62470
Thanks!

Authentication is not optional. Configuring it yourself is optional, but bitcoind never accepts RPC connections without explicitly or implicitly configured username/password.

So, I just added user and pass from file /root/.bitcoin/.cache.
And get this:
curl --user __cookie__:96fea535b009e62ddffe1c6f5090c50396d17e7f96d0b0a75eb580bdd1771d29 --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getinfo","params":[]}' -H 'content-type:text/plain;' http://127.0.0.1:8332
