MegaCoin - Stratum-miner error - results in no blocks solved? Setup explained

EDIT: As I submitted this - we DID find 3 blocks so I guess it's all working. However - anyone know what that error is? Hopefully the info below from my notes helps someone else setting up a pool on Ubuntu 12 Grin

EDIT2: I still wonder if all blocks are being cashed in and not being missed. It seems to be working but want to make 100% sure.Will wait for any replies

Hi guys.

i either have bad luck finding blocks...which I don't think is the case at this point - or there is a problem.

I see this in the stratum.log:

Code:

What is this:

2013-08-06 21:20:09,668 INFO template_registry template_registry.get_job # Job id '166' not found

Would this result in not solving/lost blocks? Or is it normal?

I use stratum-mining fork from moopless - and php-mmcfe-ng frontend by TheSerapher. I have pushpoold installed but not using it - just stratum.

It's my understanding that stratum and mmcfe-ng (and megacoind) are all that's needed to get this setup going (aside to obvious dependencies like mysql and libs,etc ..).

I've have solved blocks before but have had to rebuild the whole pool and db due to problems experienced through tweaks trying to improve the pool, and me being a n00b basically.

So....Anyone have any info on this - or advice on how to setup the pool for MegaCoind?

Those jobs btw seem to NOT happen in the beginning when strating twistd -y launcher.tac (stratum). They happen to start when someone with lots of hash power is in the pool. Is that normal?

Thank you for any help you can provide. I have done a lot of research on this, and have ran in to this uncertainty...for all I know this all may be working ok and we haven't found a block...but so many changes to perfect this - I'm not sure. I feel we should have solved at least ONE block by now at this low difficulty.

For anyone having issues with this setup - here are a basic layout of the notes I followed to set this up:

Code:

I installed Apache2 as well for HTTP, so apt-get install apache2 and libapache2-mod-php5 if you don't have something else in mind.

Installed All Dependencies
mkdir ~/MiningPool
cd ~/MiningPool
git clone git://github.com/litecoin-project/litecoin.git
cd litecoin/src
# Compile litecoind
make -f makefile.unix USE_UPNP=-
# Copy to system path
sudo cp litecoind /usr/bin
nano ~/.litecoin/litecoin.conf
put in and save:
rpcuser=user
rpcpassword=password
rpcport=9332
rpcallowip=127.0.0.1
server=1
daemon=1
gen=0
litecoind
(should run in background just fine now hopefully!)
cd ~/MiningPool
git clone https://github.com/Tydus/litecoin_scrypt.git
cd litecoin_scrypt
sudo python setup.py install
sudo easy_install -U distribute
(this breaks it for some reason - do this fix:)
wget http://python-distribute.org/distribute_setup.py
sudo python distribute_setup.py
sudo easy_install stratum
cd ~/MiningPool
git clone https://github.com/moopless/stratum-mining-litecoin.git
cd stratum-mining-litecoin

LITECOIN_TRUSTED_PASSWORD = 'password'

litecoind getaccountaddress "" (to get your wallet for the above config)
Leave POOL_TARGET = 16 as default setting unless you have preferred alternative setting ;)
Can't start it yet cuz we haven't made the database - we'll do this with mmcfe-ng next!
cd /var/www
sudo git clone git://github.com/TheSerapher/php-mmcfe-ng.git mmcfe-ng
cd mmcfe-ng
sudo git checkout next
cd sql
mysql -u root -p -e "create database mmcfe_ng"
mysql -u root -p mmcfe_ng < 000_base_structure.sql
mysql -u root -p mmcfe_ng < 001_unique_email.sql
mysql -u root -p mmcfe_ng < 002_monitoring.sql
mysql -u root -p mmcfe_ng < 003_accounts_anonymous.sql
mysql -u root -p mmcfe_ng < 004_tokens_invitations.sql
mysql -u root -p mmcfe_ng < 005_accounts_nofees.sql
mysql -u root -p mmcfe_ng < 006_payouts.sql
cd /var/www/mmcfe-ng
sudo chown www-data public/templates/compile public/templates/cache

sudo cp public/include/config/global.inc.dist.php public/include/config/global.inc.php

sudo nano public/include/config/global.inc.php

edit this file to match your settings

Run launcher.tac

cd ~/MiningPool/stratium-mining-litecoin/

sudo twistd -y launcher.tac

Open your web-browser and go to your server's IP. If it fails to load - you need to configure apache to point to /var/www/mmcfe-ng/public/ and ensure php loads :) (Google it if you must)

Bam should be working - If not make sure litecoind, and twistd -y launched :)

chmod 755 src/leveldb/build_detect_platform
Compiling in linux:
If you have the following error, use this command: mkdir src/obj ; sh share/genbuild.sh src/obj/build.h ; cd src ; make -f makefile.unix

make -f makefile.unix digitalcoind
/bin/sh ../share/genbuild.sh obj/build.h
../share/genbuild.sh: 33: ../share/genbuild.sh: cannot create obj/build.h: Directory nonexistent
../share/genbuild.sh: 34: ../share/genbuild.sh: cannot create obj/build.h: Directory nonexistent
make: *** [obj/build.h] Error 2

if compiling you get error at sendalert.cpp and sendnews.cpp - you have to edit those files and change the case on:

Sleep(500);
^ Change to small s
sleep(500);

Silly but fixes it for me :)
