Pushpool - Tech Support

[hippiex]

You should recieve shares... when connected to pushpool... My Litecoin pool gives met a share every second or so...

Hi OversightNL,
Do you know how to make sure that i am really mining ... I've set pushpool to use litecoind (using git clone https://github.com/ArtForz/pushpool.git) , connected my client and cgminer is processing like crazy... the problem is, i just can't see any message saying that i am actually doing any progress.

Is there a way to make sure it is really working ? I really don't want to spend electricity for nothing....

Cgminer:

No idea if it is working or not....

What's going wrong here?

I've installed pushpool for litecoind.

When i connect my miner, pushpool outputs this:

./pushpoold -E -F --foreground --debug=2 --stderr

It does'nt say the miner is connected. Why? Every 30 seconds or so, a new getwork request is done, but nothing else seem to happen...
Also: My miner mines @ 100Khash, but does'nt get shares (accepted). The database also doesn't get filled, it does not show active miner, nor shares.

It kinda feel's like it's solo mining.

[lavajumper]

now 30000 shares, still no upstream_result with "N" or "Y"

problems?

upstream_result is when the pool detects a share at or higher than the network target, ONLY THEN does it allow it to get to bitcoind. That's why, basically.

I'm having this issue running pushpool against a private testnet (difficulty 0.00024414). Right now I've got 10,000 shares and less than .01% are getting submitted upstream. All of those submitted get returned as false (upstream_result = "N"). Also, cgminer constantly reports "Found block"

When I point cgminer directly at litecoind (the same litecoind), it mines blocks so fast I have to drop my intensity to see the output.

I've tried almost every combination of:
setting rpc.target.bits everywhere between 1 and 32.
rpc.target.rewrite true and false
longpoll.disable true and false

I've commented out the check in the source for insufficient target to prevent submission. This results in all work being submitted to litecoind and all being rejected.

I've fiddled with the EASY_TARGET def, blindly.
I've tried alexhz, viperaus and Artforz's versions, though almost all of my edits were done against alexhz's.

Here's some of the output with rpc.target.bits : 16

Code:

None of these shares were submitted upstream.

I'm testing on an Ubuntu 32bit 10.04. The compile is clean.

A couple of things I've noticed:
- if I reset the testnet to go back to zero, I can usually mine the first block. Not always.
- commenting out rpc.target.bits results in many shares being accepted between found blocks, but the "Found block" is still false.
- setting rpc.target.bits : 1 results in the above, but much slower. ( I read somewhere that the lower the rpc.target.bits, the less shares get submitted).

I've read other people in this thread having this problem, but I haven't found any resolution. Did someone solve this and I missed it?

I've also wondered if everything may be running right, just there's something about testnet that's incompatible?


EDIT: This is solved. Thanks for the PM's!  I didn't have a blocknotify process in place. In case anyone else is having trouble finding this, Longpolling requires that a SIGUSR1 signal is sent to the pushpool process when a block is found (new block available) which in turn notifies connected clients that they need new work. Populate an entry in litecoin.conf (or pass on command line).

Code:

blocknotify="/full/path/to/process"

I wrote my notifier in php.

Code:

#!/usr/bin/php
<?php
$log=fopen("/opt/work/notify.log","a+");
$date=date("Y-m-d H:i:s");
fwrite($log,"$date\n");
exec("killall -s SIGUSR1 pushpoold");
fclose($log);
?>

[2013-06-01 11:30:17.793631] error: using aux chains but getworkex not available

I used this pushpool fork before: https://github.com/alexhz/pushpool Then I've desided to change it to https://github.com/CryptoManiac/pushpool for better NVC support. With CryptoManiac fork I see that pushpool and miner working but no one shares counted. Even in miner log I dont see that any share founded.
Then I tried roll back to alxhz for but now it get error about getworkex not available. Is there a way to show him that getworkex?

Thanks.

It appears you need a getworkex RPC command available on your novacoind, which you do not, then again it's something about merge mining, so It'd be best to disable that.

Hi Folks

I have installed PushPool but when I run the process I see the following:


~/ppool/sbin$ ./pushpoold -E -F -D 2
[2013-06-02 08:59:42.951470] Debug output enabled
[2013-06-02 08:59:42.951880] Forcing local hostname to localhost.localdomain
[2013-06-02 08:59:42.955115] Listening on host :: port 8342
[2013-06-02 08:59:42.955226] Listening on host :: port 8341
[2013-06-02 08:59:42.955321] Listening on host :: port 8332
[2013-06-02 08:59:42.955398] Listening on host 127.0.0.1 port 8338

I then do a ps -ef|grep push and find the process isn't running.

Are there any log files I can look at to figure out why the process is dying. I was hoping that I would see an error output to the screen if the process is immediately crashing out.

Any assistance appreciated.

*** Resolved this. It ended up being a missing underscore for the MySQL username. As always it always ends up being something simpler than you think.
Its ashame that pushpool doesn't throw out any useful errors to give you a pointer though :-)

This is a known issue with pushpool not initializing OR warning if MySQL server isn't running or wrong credentials are supplied.

Anyone here have pushpool properly working with ltc? If so do you care to share what git depo you used and maybe a small walk though?  I have a lot of gpu miners and with diff on btc increasing i want to self mine with ltc..

Hi gateway
this fork of pushpool works with litecoin, but it does not support stratum.

Does anyone know something about stratum support by pushpool?

[jgarzik]

Does anyone know something about stratum support by pushpool?

I would be happy to merge litecoin and stratum support into the pushpool repo, if someone created a pull request.

[BitCoins06]

I have the same problem as others. No shares going into the database or into shares.log.

There is a pretty detailed post (https://bitcointalk.org/index.php?topic=10321.msg2038129#msg2038129) a page or so back that has the exact same problem I do, so Im kinda hoping somebody will answer him..

Mysql setup right and running? Created user with passwd in mysql? Put in config file?

Shares.log placed in /tmp for debugging purposes since any user can write there?

Pushpool running and what does cgminer show?

What coin are you trying to mine? Coin daemon running and setup right in config file?

[phazon307]

I would like to start a small mining pool as well this seems very difficult and would take up all the free time I have in a day. I do have a lot of free time but don't know if I want to sit in front of a PC all day and night.

Your best bet is to start learning linux and if you already know it setup a pool for an alt coin where little hashing power can still find a block. It is not really necessary to have a web front end right away.

I keep getting :
server.json: JSON parse failed

When I do:
pushpoold -E -F

This is my server.json:

What am I doing wrong?
