[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[smoothrunnings]

It's working for me so far Rick, knock on wood.

You could always block or turn off port 9333 as a temporary measure and enable it later.

I should look at the code but I thought it would block the peer that sends bad shares before it went into it's loop that kills everything.  I have a monit script setup to restart it when it starts to act up. Unfortunately Apple AirPorts cut the connection for a minute or so when changing that level of settings.  I could just add an iptables rule..

Sounds like something I should find for openSUSE; the script that restarts it when something acts up.

[smoothrunnings]

There is currently a problem and a fix is being worked on. For now, refusing incoming connections (--max-conns 0) is a temporary solution. Expect more news in the next half hour.

Just had it happen to me after applying the fix a couple of hours ago. I have added --max-conns 0 to my startup until a more perminate fix is found.

Thanks,

Yeah I had another drop 2 hours after I pulled from git.

Here is working fine so far!

You're comparing with others in p2pool.  I'm comparing with non p2pool.

You could think in p2pool way.
If your good share rate is higher/lower than others in p2pool,
your average income is higher/lower than others in non-p2pool.
Then take low miner fee, tx fee, p2p, and coinbase tx as pros, and higher variance as cons.

Also, unless things have changed, p2pool can not be reliably run on a home DSL connection.  That means folks like myself have to use a public node or suffer higher than normal rejects (and normal is high enough thank you!).  That means you have two choices: trust the op of that public node, or get higher rejects.  Both negate two supposed benefits of p2pool.

The pool I ran for bitcoins averaged ~110-115% efficiency, but that was on a dedicated server (not a VPS) in Germany with 1gbit/1gbit switch (200mbps guaranteed but in practice could 99% of the time get 80MB/s + ).  Averaged around 3-5% DOA for me and about 2-4% orphans.

When I initially tried to set up my home connection, I was getting around 0-1% DOA and 15-20% orphans.  A few percentage of the orphan rate was from being in the US instead of France/Germany/Netherlands where most of these dedicated servers & VPS are running.  Most was from my 768kbps upstream cap.

Later on I was able to set it up w/ 0-1% DOA and an orphan rate under 10% (though it still wasn't as good as just using German remote server, after share time got changed to 30s)... anyway, the deal is, just have bitcoind connect to 1 or 2 servers & also your p2pool node need only connect to a handful of servers...  you just have to pick the right ones.  I have no clue what those are anymore.  (ie, change outgoing connections to 0 and handpick the servers to connect to)

ed: i think you can find a VPS for a couple of bucks to run a bitcoind relay on

Try the most recent commit (012a8830), if you can. It bans peers that send invalid shares (for an hour), so it should help.

Do I need to restart the p2pool or just a git pull should work?

Thank you.

go into p2pool directory and do a git pull then restart

Finally someone with a brain who spelled it out, what to do! LOL

Thanks for your help!

Wait so you know how to do that but my mention of running last commit didn't trigger this?

Obviously you haven't been paying attention in the other thread on setting up P2Pool? I have only had my pool setup for uhm, close to 24 hours now. With the questions I was asking its obvious I didn't know much about linux otherwise I would have been done ages ago. Thanks to the guys over at the openSUSE forum who did a great job at translating the ubuntu mumbo jumbo stuff into openSUSE.

It would have been more simpler if you had said.. run git pull on p2pool instead of saying it the other way. LOL

There is no need to complicate your life and the life of others.

Thanks,

Sorry that's cuz I don't know how to do it that far

That's a decent idea about running a VPS for a bitcoind relay.  I could stick p2pool on there too while I'm at it.

It still doesn't solve the high share difficulty problem though.

Youre right on this, and because sharedif is so high - there will be less and less new users. Its impossible to try to get the best out of p2pool with lets say 120gh when you get from 0 to 3 shares a day.

Sad but this is it. Or is this shit.

Been up for about 16 hours now.  Had one incident about an hour in, but it's been clean since then.

Thanks!

When is it safe to try removing --max-conns=0?

[bkminer]

Is anyone else seeing errors in the p2pool log when they hit the graphs.html page?

Edit: my lack of python experience, which I will have to fix

[ksenter]

Just for comparison... since the common belief is that the high variance and high share difficulty doesn't affect your payout, let's compare.

I have 38GH/s.  It's a cube, I brought it online almost 13 days ago, pointing to BTC Guild.  Since then my total payout has been 0.12764.  According to BTCGuild stats, we're at 99.7% luck for the last 14 days, so I'm pretty close to "average" payout.  I'm not counting the ~0.21 NMC I've earned.

Can someone who has significantly larger hashrate post their comparison?  Ie, what you made in the last 13 days scaled down to 38GH/s?

EDIT: I'd also like to see someone who has an equivalent hashrate or less.

M

January 6-18 with my 30GH I got 0.1261.  But I don't think that's the best representation.  Lets check again when you have a longer period.  There was a few days where I got 0 and then a short period where I got an abnormally large payout.  I know variance is normal but this was the most extreme I'd seen up to this point.

[smooth]

Its impossible to try to get the best out of p2pool with lets say 120gh when you get from 0 to 3 shares a day.

0-3 shares per day is just fine. The shares are active for a day and a half, so almost every single day you will have one or more shares working. Your daily earnings will fluctuate but only rarely to zero and over relatively few days it will average out.

With a much lower hash rate like 10 GH you could make the argument it will take much longer to average out, although I still maintain at that point the numbers are so small the variance doesn't matter. If you get $0 instead of $1 on one day and get $2 instead of $1 on another day you're not going to go bankrupt over it.

That's a decent idea about running a VPS for a bitcoind relay.  I could stick p2pool on there too while I'm at it.

I like this idea of a VPS with the p2pool and bitcoind nodes on it. Will probably be trying that in the new few days. Anyone else have any tips on doing it?

Share difficulty is currently at 1.008 million.  With 10 GH/s it'd take you 5 days to get a share.

Does anyone knows why or if p2pool is not calculating the pool fee we set?

Like I get no payouts to the pool's address.

You get shares and they're random but they add up long term

The payout for the miners is working! The one that doesn't work is the payout for the pool fee! Like I set up the pool to have 2% fee. I'm not getting this payment!

I know how to set up bitcoind on a VPS generally. Just wondering about the p2pool aspect of it. For example, is it better to have bitcoin and/or p2pool local nodes that connect to their counterparts on the VPS or just have the miners connect directly to p2pool+bitcoind on the VPS?
