the bitcoind daemon doesn't respond to commands For some reason, the daemon doesn't accept commands neither RPC, nor command-line.
I'm running the prebuild 64 version of the bitcoind. It already downloaded all blocks etc and as is happyly running in the background, however it doesn't allow any commands to be sent. For example:

./bitcoind getinfo
error: couldn't connect to server


I tried with a config file having only the rpc user and pass, then I extended it with different params, and of course have restarted the daemon each time. Still - no luck.

The debug.log is not telling anything either. It just dumps the normal intensive communication, like…

 2013-12-07 22:01:40 received getdata for: tx

but no trace from my attempts to call a simple command.

I tried to google the problem without luck.
In bitcoin.conf, make sure you have the following lines:

rpcuser=your-userid
rpcpassword=your-password
server=1
