I know this is the wrong forum for this but there is something I have noticed happen with p2pools that go a long time between finding blocks.

The Share data Timestamp gets out of sync with the Block Timestamp (share example below).

After enough blocks are found it eventually syncs back up.
The main problem with this is that the share difficulty stays at the lowest possible rate until it does sync causing p2pool to overload itself when large miners come on.

A not so important side effect is that if you have irc announce on it does not report found blocks until it is back in sync.

If anyone is inclined to look into this I would be forever thankful.

Hm this is interesting and worth investigating. However, now I have no idea how to use p2pool over TOR?

I don't have an answer for the original question, sorry, but will say that p2pool over tor is a horrible idea.

One of the main trade-offs for using the onion router is speed for privacy, you loose a great deal of speed to gain incremental privacy.

As a miner on p2pool, the competition is tough and speed is everything; latency from miner to node, node to peers, bitcoin's GBT latency, etc...

Tor, while an awesome project, slows things down by its very privacy centric routing nature.

Tor - great for privacy, horrible for mining bitcoin.
You are probably right so I ll have to give up on running p2pool on this specific coin. Thank you all for trying to help me, very kind from all of the ppl here.

I have noticed happen with p2pools that go a long time between finding blocks.

P2Pool power : http://minefast.coincadence.com/p2pool-stats.php = 1,5 PH/s
Bitcoin power : https://bitcoinwisdom.com/bitcoin/difficulty = 365 PH/s


no problem here.  Wink

 Angry and again ... i have a problem with the shares of P2Pool.
Shares don't rise on P2Pool command ... and Bitcoin Core debug.log indicate insane "input already spend".

 Huh someone have an explaination, or, it's again a corrupted share chain in my folder (local).

Not off topic at all.  Assuming you have a BTC p2pool node setup, you'll need to open up port 9332.  To be a "good" citizen, you should have the following ports open:

8333 - BTC peers
9333 - p2pool peers
9332 - p2pool miners

Note that opening up 8333 and 9333 will allow multiple peers to connect and you will see higher bandwidth usage.

Not in the bitcoind conf file, add it to the p2pool start up command, like so:

Code:
~/p2pool/run_p2pool.py --give-author {yourdonation] --fee [yourfee]

Add your number without the [], leaving a space between commands.

You type it in a command console to start p2pool. Have a read of the readme, particularly the section on running p2pool:

https://github.com/forrestv/p2pool

or type in:

Code:
python run_p2pool.py --help

..to see a list of commands  Wink

You start p2pool like this:

Code:
./run_p2pool.py --give-author 2 --fee 1

That will give forrestv a 2% donation and will charge anyone who mines on your node a 1% fee.

Yes.  You will need to stop the currently running p2pool instance, and then start a new one (the python command) for whatever OS you're using.  I posted the Linux/OS X commands.  Somebody who runs a Windows install could give you the proper syntax for that OS.
