bitcoind getinfo or getbalance freeze I am a bitcoin newbie. I am testing solo mining (I know it is not financial feasible in general). I installed bitcoind on Debian and it ran okay as far as I could tell. I've experienced a couple of problems. The size of the bitcoin data directory is still growing when I use:

du -ks .bitcoin/


I ran

./bitcoind getinfo


and got information like this:

{
    "version" : 80600,
    "protocolversion" : 70001,
    "walletversion" : 60000,
    "balance" : 0.00000000,
    "blocks" : 225436,
    "timeoffset" : 0,
    "connections" : 9,
    "proxy" : "",
    "difficulty" : 4367876.00084220,
    "testnet" : false,
    "keypoololdest" : 1389424771,
    "keypoolsize" : 103,
    "paytxfee" : 0.00000000,
    "errors" : ""
}


When I ran

./bitcoind getbalance


I got 0.000000000

The problem is sometime,

./bitcoind getinfo


simply freeze and I have to use Ctrl-c to kill it.

Another problem is I cannot connect to bitcoind using

./minerd --url http://127.0.0.1:8332 --userpass username:password


The result I got is:

Again, I had to use Ctrl-c.

Any information is appreciated.
Usually this type of conf file works :

server=1
daemon=1
rpcuser=any_username
rpcpassword=any_password


if not then allow ip 127.0.0.1 in bitcoin.conf 

rpcusername=your_usename
rpcpassword=your_password
allowip=127.0.0.1
allowport=8332


This may help, you may also try allowing ip 0.0.0.0 if both of the above does not works
