Pushpool - Tech Support

[Furyan]

I'm also stuck at pushpool configuration. I read through the whole thread and the only solution to get rid of the error messages when connecting a miner is to have the rpc port (pushpool) pointing to the rpcport configured in bitcoin.conf.

However when i connect my miner I get error 500.

some lines are cut by "$" because i copied/paste it from a text editor, but those shouldn't be interesting...

bitcoind runs as normal user, and I'm able to connect my miner directly to bitcoind (using rpcuser and rpcpass).
pushpool and bitcoind run on the same machine.

the password is stored unencrypted in the table.

any help is appreciated :-/

Your ports are all messed up.  Try this:

bitcoin.conf:
rpcport=8335 (just choosing something that isn't already taken and isn't 8332 or 8333)


server.json:
(at the bottom):
"rpc.url" : "http://127.0.0.1:8335/",

(at the top):
                # HTTP JSON-RPC protocol, port 8332
                #{ "port" : 8341, "protocol" : "http-json" },
                { "port" : 8332, "protocol" : "http-json" },

Now you'll expose 8332 to the internet via pushpool, and bitcoin/pushpool will communicate over 8335 on localhost.

That configuration should work for you.

Your miner is getting an empty reply from the server because it's trying to connect to bitcoin directly (rpcport=8332, remember?) Bitcoin only allows connections from localhost by default so it simply slams the connection shut.

I configured the ports as you told me, but i get error 500 nonetheless.
8335 in bitcoin.conf, 8335 rpc.url and connect the miner to the port i configured in HTTP JSON-RPC section

Just thought I'd like everyone to know that I got my first donation for 0.0005 BTC fromt this page thanks everyone for your contribution you've been a real help.
I mean yeah you all made your own pool and made tons of BTC and I'm really happy that I was even given this amount you guys are sooo giving



Seriously tho, i got some lolz out of that donation.... that was donation enough!

isn't the satisfaction to have helped someone not donation enough?

[Xenland]

Honestly it doesn't matter at this point, before It would have helped to have a couple of Bitcents here and there at the time of writing the tutorials

[bully]

btw i was able to get it to work, with the configuration which gave me error 500 before.
maybe it doesn't work when the keychain isn't completley downloaded?

Ah, no it doesn't.  FYI during that period, if you submit any RPC requests to bitcoin directly via the command line it will respond with an error message saying the blockchain is currently downloading.

when i connected directly to bitcoin while the keychain was downloaded it gave me that message, while connecting to it through pushpoold gave me an error.
well, just to know...

[Keninishna]

any fix to pushpoold not responding after a day or so?

[Furyan]

any fix to pushpoold not responding after a day or so?

Have you made any changes to the stock code?

What do you see as the output of "netstat -anp"?  If you're hitting your ulimit with too many TIME_WAIT's that can cause it.

[vernik]

hi, after command  "netstat -anp" i had to much "CLOSE_WAIT", not "TIME_WAIT".
How to close this connections? i think this is why pushpoold does not work after some time.

Does anyone know what these parts of the pushpool server.json file are for...

Code:

        "listen" : [
                # binary protocol (default), port 8336
                { "port" : 8336 },

and

Code:

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

Do the miner clients need to connect to those ports?

The binary protocol is documented here:  https://bitcointalk.org/index.php?topic=3493.0

No mainstream miners support it, so most people will not need it.

I have fixed my problem where puspool stopped working with error too many files opened now it collapses with...

"HTTP request failed: couldn't connect to host"

A restart of pushpool gets it going again.

As anyone seen this before?

[jackie]

I'm running pushpool0.5.1 and have a problem with it. The problem is that my pushpool is working for about 15min-3hours and everything looks normal, but after some time when I try to mine and I get this error: Problems communicating with bitcoin RPC . Pushpoold process seems like working as allways. But after killing and running pushpoold again everything works normally...
My VPS is with ubuntu-11.04-x86 and 768 Mb of RAM. Bitcoin client is in another server (windows vps).
Maybe someone knows how to fix this problem?

Yeah switch to PSJ it was the only way I was able to resolve that issue.  The people here know how but they will not tell you they need to keep an upper hand.

I plan to put an end to this, I'm going to publish everything I find and there is a lot I have learned they are hiding. 

But if I where to guess at the problem you need the 4diff patch for bitcoind that should clear it up for you.  Also you should not even bother trying to mine with out that patch as it cleans up duplicate work.

Finally, here is another tip pushpool is not production ready code it's example code that just functional enough for you to rewrite it for your pool.

Good luck dude this space is cut throat centralization of mining and it has to to stop because the next phase will be... Consolidation of pools after the next bitcoin bubble or when bitcoin hit supper lows as all bubbles go from WAY over valued to WAY undervalued.

Hi!

 After days trying this... I'm sure that I'm close to start my first pool!

 I'm running: pushpool-0.5.1, mysql, memcached and Litecoin (with LongPool patch applied).

 I run pushpool with: "pushpoold -c /home/administrativo/server.json -D 2 -E -F"

 Every time litecoin found a new block, I see at pushpool: "USR1 signal received, flushing LP waiters"

 All appear to be working okay but, when I connect my minerd at my pool, I don't get any "PROOF OF WORK RESULT: true (yay!!!)", even after minutes!

 But why?!

EDIT: AND... I don't see the message "Long-polling activated for http://mypool:9334/LP"... Any tips!? I disable it for tests... lol

 I'm planning to use the mmcFE web interface, it is pretty awesome and clean!

Best!

Mmmm... Maybe because original pushpool does not support Scrypt!? lol

Anyway, I'm still unable to find a valid share at my pool...
