Awesome program! I'm using it for mining Litecoin and it's working fantastically. I have a question though: How can I get loads of stales and a lower hashrate when using the binary from this thread for mining, yet when I download the repository and run it with python, my hashrate is much higher and stales much lower. I'm not complaining of course, but it's kinda weird.

Keep up the good work! Smiley

The binary 11.2 release was prior to two important fixes for LTC mining.  You currently need git to use p2pool LTC.

Ah, that makes sense. Thanks for the answer. I'm glad all is well!
I'm getting around ~10% (vs ~20% average of the entire pool) DOAs and 126% efficiency. I'm guessing these numbers are good?
Still that looks like quite a bit of work wasted. Is that normal and to be expected?

Thanks again!

You're doing very well, and your work is not being wasted at all.

Short story: p2pool DOAs are still valid blocks and can still payout if they have a higher diff than the bitcoin network difficulty and thus are accepted by bitcoind. They just don't end up on the p2pool internal sharechain. As long as your efficiency is ~100% (or in your case > 100%), you have a well tuned and properly running system.

I wish this was working for me. I'm a big fan of p2p technologies but despite watching messages scroll up my screen for the past few days, I'm still unable to participate. No apparent way to tell if things are healthy or not. I appear to be connected to a number of peers, I have my port forwarded, I'm running the downloaded windows binary, it should be a straight-shot as far as I can see but nope.

Am I really the only one having troubles or are others trying and just walking away? Is anyone driving this thing?

Open a browser on the machine running p2pool and go to 127.0.0.1:9332 (this port number could be different if you are using it to mine other coins than Bitcoins. Just use the same portnumber as you're using to connect your miners to your p2pool instance).
Should give you a page with stats and graphs where you can have a look if things are working.

It seems that you are the only one with this specific problem. Since others can't reproduce it, it is harder to debug (and sounds like a configuration error, but you seem to know what to do to configure it properly and it still is not working). Maybe windows firewall? settings If you had a more recent python/twisted version from your linux distribution you could test that too to isolate if it is a windows configuration problem or somewhere else in the network (is your ISP filtering packets?)

I can share my experience: p2pool on a raspberry pi (raspbian wheezy), an ubuntu 12.10 laptop, and debian wheezy server all work with no problems with the default configuration. There are > 200 users using p2pool currently, and as far as I can see on the forums you're the first one to report the problem (which is why everyone is asking you to check configurations).

I hope you can get it working, perhaps stopping by #p2pool on freenode will get you some real-time feedback as opposed to long delay on forums.

EDIT:
Actually, could you try installing a more recent linux distribution in a VM on your slackware install? That should be easier than a whole machine upgrade and may show you if it is a windows or network problem.

Definitely not Windows Firewall as I have that turned off completely. I do have a couple of other Linux boxes lying around so I can give those a try. Might even be worth seeing about firing it up in a VM I suppose.

can't you just see if it's working from the log file in the p2pool/data/bitcoin directory?

what exactly is the issue, getting like 100% stales, can't mine on your own node, or?

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

Here's his problem (on the previous page of this thread) - it appears that he connects to peers then they timeout.


Well, I appear to be connected to about 7 peers today but it's all time-outs and handshake time-outs. I guess I'll check to make sure my network is OK but I haven't had any issues with anything else. If nothing else, it's probably about time I installed wireshark anyway.

But there is definitely some communication going on as well. I ran the wireshark. Unfortunately the connection is not human readable but it seems I did maintain a connection to one host for at least a while. I've gone ahead and just deleted the whole p2pool thing completely and started again with a fresh download. It may also be worth trying on another Windows machine too (though that is not a long term solution)

Bitcoin. I didn't do any --network, running it with no options.

When I go to the graphs, they are mostly flatline except the traffic rate and latency graphs show activity.

HELP:

I was a previous user of p2pool with no problems for months; i used it on bitcoin as well as litecoin and terracoin;

I did  afresh re-install of windows re-downloaded and set-up my coins and p2pool etc.

P2pool launches with no error and connects to the network.

When i launch my  miner to connect it connects and finds the p2pool network but results in this error and no shares are submitted. please help!!!



Thank you for the help!!

This error CAN jump when you connect new miner, but it is harmless.
Try compile latest git, it is fixed.

I was hoping it was harmless so i let it run for 20 minutes the issue is that it appears to not be harmless as the local hashing power never reports anything other than 0 mhs.

as for compiling the latest git i do not have teh smarts to do such a thing and i am running the latest windows binary on the github.

Do Avalon ASICs work with p2pool out of the box?  If not, does anyone know what settings need to be used?
Thanks!

simple answer, yes. long answer no, you need a special build of p2pool and the firmware we have made to fix delays and absurd long poll wait times because of the avalon driver built in delays.

To those just joining the conversation, no p2pool or cgminer developer had access to an avalon until a user, Aseras, graciously donated his machine time to a cgminer developer this week. All avalon owners owe him a thank you for working out the new firmware and contributions to the cgminer code (that has not been released yet) along with ckolivas.

test firmware is available. PM me if anyone wants it. it has a newer cgminer 2.10.5a build that has some tweaks and bugfixes and seems to be much more stable. it has better longpoll and less delay, making p2pool slightly better but still > 20% DOA. efficiency is up to 95% or so, but so many rejects and DOA on p2pool.

based off of latest gits by xiangfu and ckolivas. It is basically following these directions https://en.bitcoin.it/wiki/Avalon ( which don't work yet BTW debugging with xiangfu to make them idiot proof )

development should continue slowly. trying to work out things.

I'm really working on p2pool, quickly coming up to speed in python right now mostly it's just hacks and workarounds to make it work. I may make a public fork, but considering my recent experiment and crashing the terracoin network for a day, I'll hold off Cheesy

ckolivas is trying to get code better as much as possible and xiangfu is doing them same plus bugfixes and better avalon drivers internally.

Well, in a case of "when you have eliminated the impossible, whatever remains, however improbable, must be the truth", I turned off QOS on my router (Tomato based) and though it's still now downloading shares, the output now gives me a lot more confidence. Odd as though it wasn't in the top tier, it should still have had plenty of bandwidth. Oh well. Hope to be mining in the pool asap. I'll get around to debugging the QOS when I can.

Edit: now mining. Yay!

It's looking like you broke it worse than that since the difficulty swung back and forth, but in a way you've now exposed the fact that a rolling daily average for difficulty was not the proper way to fix the underlying issue Cheesy  EDIT: Actually, it seems to be stuck for 5+ hours right now, other miners abandoned it because difficulty got too high. Maybe a few minutes on with your avalon it to get some blocks moving again would help things.



Unrelated question for anyone - I've not had a chance to peruse the P2Pool source. How hard is it to add other coin networks? With TRC dying/dead a day after I decided to point a miner at it for the first time, I'm curious to see how things like nvc & ppc perform, but the pools I've tried are fairly unstable.

I've spent quite a bit of time hacking on the Avalon(s) the last few days thanks to Aseras and then Xiangfu giving me access to them. I've come to the conclusion that any latency issues that prevent it mining on p2pool should be resolved in the next cgminer release incorporating the changes I've committed to the code. The max latency for restart should be on the order of 100ms now which is fine even for 10s longpolls. Hopefully it will talk to p2pool better via stratum as well.
