I created pandacoin p2pool on my home server. http://dr-nona.office-on-the.net:9444
When I tried these sources: https://github.com/pandacoin-official/p2pool-rav
I have found that they do not work.
Changed it a little.
Download sources:

Code:

git clone https://github.com/pandacoin-official/p2pool-rav p2pool-pnd

Then in ~/p2pool-pnd/p2pool/networks.py completely replace pandacoin description into this:

Code:

    pandacoin=math.Object(
        PARENT=networks.nets['pandacoin'],
        SHARE_PERIOD=10, # seconds target spacing
        CHAIN_LENGTH=20*60*60//10, # shares
        REAL_CHAIN_LENGTH=20*60*60//10, # shares
        TARGET_LOOKBEHIND=200, # shares coinbase maturity
        SPREAD=30, # blocks
        IDENTIFIER='e40ef614eeebb383'.decode('hex'),
        PREFIX='502f757a499bf601'.decode('hex'),
        P2P_PORT=8334,
        MIN_TARGET=0,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=False,
        WORKER_PORT=9444,
        BOOTSTRAP_ADDRS='dr-nona.office-on-the.net'.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-sawa',
        VERSION_CHECK=lambda v: True,
    ),

and in ~/p2pool-pnd/p2pool/bitcoin/networks.py replace on this:

Code:

    pandacoin=math.Object(
        P2P_PREFIX='c0c0c0c0'.decode('hex'),
        P2P_PORT=22445,
        ADDRESS_VERSION=55,
        RPC_PORT=22444,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'pandacoinaddress' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: 10000*100000000,
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        BLOCK_PERIOD=60, # s
        SYMBOL='PND',
        CONF_FILE_FUNC=lambda: os.path.join(os.path.join(os.environ['APPDATA'], 'PandaCoin') if platform.system() == 'Windows' else os.path.expanduser('~/Library/Application Support/PandaCoin/') if platform.system() == 'Darwin' else os.path.expanduser('~/.pandacoin'), 'pandacoin.conf'),
        BLOCK_EXPLORER_URL_PREFIX='http://pnd.showed.us/block/',
        ADDRESS_EXPLORER_URL_PREFIX='http://pnd.showed.us/address/',
        TX_EXPLORER_URL_PREFIX='http://pnd.showed.us/tx/',
        SANE_TARGET_RANGE=(2**256//1000000000 - 1, 2**256//1000 - 1),
        DUMB_SCRYPT_DIFF=2**16,
        DUST_THRESHOLD=1e8,
    ),

And it works, you can check out.
The question is, what are the correct parameters to specify to connect my pool to others:

Code:

         IDENTIFIER = 'e40ef614eeebb383'. Decode ('hex'),
         PREFIX = '502f757a499bf601 '. Decode (' hex '),

Parameters in the source on the github cause an error.

Thanks.
Everybody can mine in my pool http://dr-nona.office-on-the.net:9444 or connect your pool to my taking these settings.
When it's hard to mine other coins I switch to my pool for mining pandacoin.

Thank you. The repo was still in draft and I decided to stop committing to it because of the random block reward.

Now that we have a static reward everything should be fine regarding p2pool.

Also see https://github.com/Rav3nPL/p2pool-rav/pull/62.

As for IDENTIFIER and PREFIX: They do not need to be the same, as long as the values are of 19 numbers converted into hex, p2pool will function correctly.
