PushPoolD

[Ztjuh]

Hi,

I've just followed this tutorial: http://forum.bitcoin.org/index.php?topic=10321.0

But when I start pushpoold I get this:

username@server:~/pushpool$ pushpoold --config=./config.json --debug=2 --stderr --foreground

I've searched the forums, but couldn't find a appropriated answer There must be something wrong Something I forgot, or something that's not described in the topic I mentioned above. Also, does bitcoin(d) have to be running, and if so, how should it be configured, because that's all not explained in the topic.

Anyway, this is my config.json:

{
        # network ports
        "listen" : [
                # binary protocol (default), port 8342
                { "port" : 8342 },

                # HTTP JSON-RPC protocol, port 8341
                { "port" : 8341, "protocol" : "http-json" },

                # HTTP JSON-RPC protocol, port 8344,
                # with trusted proxy appserver.example.com forwarding
                # requests to us
                { "port" : 8332, "protocol" : "http-json",
                  "proxy" : "127.0.0.1" },

                # binary protocol, localhost-only port 8338
                { "host" : "127.0.0.1", "port" : 8338, "protocol" : "binary" }
        ],

        # database settings
        "database" : {
                "engine" : "mysql",
                "host" : "localhost",
                "port" : 3306,
                "name" : "******************",
                "username" : "***************",
                "password" : "***************",
                "sharelog" : true,
                "stmt.pwdb":"SELECT `password` FROM `pool_worker` WHERE `username` = ?",
                "stmt.sharelog":"INSERT INTO shares (rem_host, username, our_result, upstream_result, reason, solution) VALUES (?, ?, ?, ?, ?, ?)"

        },

        # cache settings
        "memcached" : {
                "servers" : [
                        { "host" : "127.0.0.1", "port" : 11211 }
                ]
        },

        "pid" : "/tmp/pushpoold.pid",

        # overrides local hostname detection
        #"forcehost" : "localhost.localdomain",

        "log.requests" : "/tmp/request.log",
        "log.shares" : "/tmp/shares.log",

        # the server assumes longpolling (w/ SIGUSR1 called for each blk)
        "longpoll.disable" : false,

        # length of time to cache username/password credentials, in seconds
        "auth.cred_cache.expire" : 75,

        # RPC settings | Notice how this ISN'T port number 8332 this is becuase the same port number should not becuase inconjunction with the JSON RPC port other wise you'll get 500 errors
        "rpc.url" : "http://127.0.0.1:8333/",
        "rpc.user" : "username",
        "rpc.pass" : "test123",

        # rewrite returned 'target' to difficulty-1?
        "rpc.target.rewrite" : true
}

Thanks alot for the help

Yes bitcoind needs to be running configured with the rpc settings you have entered in pushpoold.

[Orodben]

For easier troubleshooting, disable memcache (in the pushpool config).  It is not essential to the functioning of pushpool.

[Ztjuh]

Thanks for helping me guys

Okay, I've disabled memcache in the config. Started bitcoind with the following command:

username@server:~/bitcoin-0.3.24/bin/32$ ./bitcoind -gen=0 -server

usnermane@server:~/pushpool$ pushpoold --config=./config.json --debug=2 --stderr --foreground

[2011-07-11 23:12:19.922736] tcp bind: Address already in use

The tcp bind error only shows up when bitcoind is started. Any pro-tips?

That means you're either running two pushpoold's (check your process stack), or you're running something else on one of the ports that pushpoold wants to bind to...

First step is to figure out what port is colliding.

[Ztjuh]

Well it's port 8332. I've checked that I've started bitcoind only once (http://gyazo.com/f2f656ef6fdc62c5319fc0fa0ad86d80.png). Then started pushpoold again, still same output.

username@server:~/pushpool$ pushpoold --config=./config.json --debug=2 --stderr --foreground

[2011-07-12 01:05:30.561110] tcp bind: Address already in use

netstat -p -l gives me te following output:

tcp        0      0 localhost:8332          *:*                     LISTEN      7137/bitcoind
tcp        0      0 *:8333                  *:*                     LISTEN      7137/bitcoind

Hope this information helps..

I've started bitcoind on port 8331 now (is this right, or doesn't it really mather? When I connect my miner to pushpoold now I get the following.

Hello,

I get the excact same problem as ZtjuH does.
Is it me or are we doing something wrong?

[Rob P.]

Your problem is Port 8332...

If you notice, in your first running of pushpoold it complains when it hits this:

username@server:~/pushpool$ pushpoold --config=./config.json --debug=2 --stderr --foreground
[2011-07-12 01:05:30.548587] Debug output enabled
[2011-07-12 01:05:30.560904] Listening on host :: port 8342
[2011-07-12 01:05:30.561040] Listening on host :: port 8341
[2011-07-12 01:05:30.561110] tcp bind: Address already in use

When compared to the output that is working:

username@server:~/pushpool$ pushpoold --config=./config.json --debug=2 --stderr --foreground
[2011-07-12 02:13:45.245495] Debug output enabled
[2011-07-12 02:13:45.268446] Listening on host :: port 8342
[2011-07-12 02:13:45.268628] Listening on host :: port 8341
[2011-07-12 02:13:45.268702] Listening on host :: port 8332
[2011-07-12 02:13:45.268767] Listening on host 127.0.0.1 port 8338
[2011-07-12 02:13:45.359415] initialized

You can see the difference is "port 8332".

By default Bitcoind listens on port 8332, but bound to the localhost address (127.0.0.1).  That shouldn't conflict with pushpoold unless you changed this line in your server.json file:

Code:

      # requests to us | "proxy" should be set to your ip address that people will connect through
      { "port" : 8344, "protocol" : "http-json",
        "proxy" : "<public IP>" },

My guess is you changed the pushpoold listen port to 8332, which conflicts with the port bitcoind is running on.

[Ztjuh]

Thanks,

Now there is one more thing..

This keeps looping since my miner would like some work, but it doesn't send any work?  

[wezzy]

Hey what did you do to end up fixing the issue above with it looping? My miner gets same messages, let me know if you did anything special.

Cheers

[wezzy]

bump! anyone?

[wezzy]

No takers?

[Stefanie Andrea]

Maybe they're dead

You have pushpoold connecting to the client on its network port. You need to connect on its RPC port (8332 by default, but which I think you changed to 8338). Also, change your RPC password in both bitcoin and pushpool, 'test123' is not secure.
