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

Sorry when you say "try the most recent commit" what exactly do you mean by that?

Update the software or something else?

Something else on github

Can you be any more vague than that?

You need to compile it from the latest commit

Where do I find the info on doing this?

I just remembered the name. Was p2pmining.

https://bitcointalksearch.org/topic/offlinep2pminingcom-hybrid-p2pool-no-fee-btcnmcixci0cdevltc-66202

There wasn't any risk to the pool operator, to my knowledge. The basic principle was the subpool had it's own share chain (or equiv - could manage with a properly designed database) to track the p2pmining users. Each share was also submitted to the real chain under the p2pmining address. When a payout occurred, it was divided among the users in the subpool based on their piece of the subchain. This also allowed merged mining to occur at a sub pool level, instead of basically solo, which is what p2pool is now.

The downside, of course, was it was a mini centralized pool, subject to possible pool operator abuse and hacking. Hacking is what brought it down..

He's serving diff 1 shares though. No vardiff, how does his server not get spammed to death?

Back then large miners were < 100 GH/s.

So should I block port 9333 for now until the issue is fixed?

I started getting the issue around 24 hours ago. Glad I can rule out some issue with my rig, anyways (set this afternoon aside to investigate, only just looked up to check in with the forum).

Godspeed, Forrest

Just as I suspected. I had my P2Pool running yesterday evening for the first time and didn't have port port 9333 open on my firewall so there was no incoming connections and it ran fine until I opened port 9333. Looking forward to the perm fix.

Right, if everyone refuses incoming connections, then the p2p system cannot work.

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.

I have the latest version off of git and the last 24 hours have been really rocky:
http://192.30.165.92:9332/static/graphs.html?Day

Rebooting my VPS (where I host the p2pool node to save my home router from being overloaded) and my miners (along with the laptop I connect to my miners) doesn't seem to have alleviated the situation, I keep getting periodic losses in connectivity.

I've alerted the VPS provider but it seems like there may be some madness from the recent p2pool update according to this thread.

What does this mean?

Quote

Punishing share for 'Block-stale detected! height(1118c0efab8b0d8005a2995d3bf2c94d3823c91859cd30799) < height(2bee57eb6cf6965b98b6f34b8118b8ad863c2dc039618f41) or 19026666 != 19026666'! Jumping from 0b46a971 to 974819b9!

Is to cover "late" shares?

If I'm not mistaken I believe it might be what's discussed in this issue: https://github.com/forrestv/p2pool/issues/80
