Hey all, Im trying to setup a sort of mini-pool for a group of friends, we have a little ubuntu box that we have on 24/7 for our teamspeak server so we figured why not give 'solo' mining a go. I understand its probably a better idea to go with a pool but together we do get a respectable hash rate in my opinion.

Ive installed bitcoind on the server and got it running, opened the port 8332, created bitcoin.conf, but from here I am lost as to what to do?
I understand that i need to setup some kind of JSON RPC system for the computers to communicate with bitcoind externally. Can anyone offer some assistance with this? Or point me in the direction of some information regarding it?

Thanks!  Smiley
 
Look, I understand that pool mining would probably be more profitable. However this isn't really about making an extra $20 down the track, I would like to set it up basically for the hell of it, try it all out, play around with it etc. If anyone can help me where I'm stuck it'd be appreciated, however if you have come in just to say "Pool mining is more profitable" then please don't post because it isn't about that.

Before going into what I know about getting it setup...

What's the total hash rate that you guys have together?

Maybe 6-7 ghashes? There is 10 of us. Can I ask why you wondered that?

Bitcoind is for managing your wallet, you're probably going to want to look at pushpool.

[Edit]: Or, just check my sig Smiley

You can run bitcoind as a server with the -daemon -server arguments, or put server=1 in bitcoin.conf

Thanks anyway though Smiley

You're probably better off going with a pool.  Using the old calculator gives this for current difficulty with 7gh/s:

ProbabilityTime
Average12 days, 0 hours, 11 minutes
50%8 days, 7 hours, 45 minutes
95%35 days, 23 hours, 21 minutes

and the Difficulty is going up to 1804823 in 861 blocks

soo it'll take more time.

Checkout this wiki article.  You'll have to make changes to bitcoin.conf to allow it.

The two main things to look for:

You need to have this on so miners can connect
Code:
# server=1 tells Bitcoin to accept JSON-RPC commands.
server=1

Make sure to have the correct IPs allowed to connect
Code:
# By default, only RPC connections from localhost are allowed.  Specify
 # as many rpcallowip= settings as you like to allow connections from
 # other hosts (and you may use * as a wildcard character):
rpcallowip=10.1.1.34
rpcallowip=192.168.1.*

I think those are the only two things you'll really need to set to be able to connect (and make sure the IPs are correct for you and your friends).

Thats what I thought too, I have done that in the config file and set rpcallowip to rpcallowip=*.*.*.* to test it until it is up and running, however any connections I send to it just dont work.

Dont I need some kind of RPC script to interface with bitcoind? For example:

Code:
require_once 'jsonRPCClient.php';
 
  $bitcoin = new jsonRPCClient('http://user:password@127.0.0.1:8332/');
 
  echo "<pre>\n";
  print_r($bitcoin->getinfo()); echo "\n";
  echo "Received: ".$bitcoin->getreceivedbylabel("Your Address")."\n";
  echo "</pre>"

Which was found on: https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)

Or do I not need this?

To interface with bitcoind running on a different machine, you would need to use a script of some sort.  Do you have a webserver setup on the same server that bitcoind is running on?

Make sure to go download the JSON-RPC class and have it on your webserver.  Your code should then look like:

Code:
require_once '(path from web root)/jsonRPCClient.php';
 
  $bitcoin = new jsonRPCClient('http://(user in bitcoin.conf):(pass in bitcoin.conf)@localhost:8332/');
 
  echo "<pre>\n";
  print_r($bitcoin->getinfo()); echo "\n";
  echo "Received: ".$bitcoin->getreceivedbylabel("Your Address")."\n";
  echo "</pre>"

Try that out.

This is what Im having difficulties with :/ I Download the JSON-RPC php package, but what do I do with it then? What do I have to configure? Is there a certain directory I should place the files?

Also with the file we each quoted, where does that go? anywhere?

Heh.... I think you may want to look up web hosting/PHP/etc.  Once you learn a little bit about that it will all make sense.

The short version is upload the JSON-RPC files wherever, you just need to put the directory (from web root) in the 'include' statement.  You put the PHP script in your web root, or wherever you want it to go.

This isn't a linux thing, it would be the same setup on any webserver.  You just have to have the json-rpc files in your web directory somewhere so that you can the include call in the PHP script is able to reach them.
