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

[rav3n_pl]

OK, liking p2pool so far. I miss being able to track my hashrate easily though. Who wants an Android app?

Just look on your node /static/graphs.html?Day page

Too much like hard work. I think I'll just rework my widget I wrote for the HHTT pool. It may need to work a little differently since the pages aren't public (and I wouldn't recommend anyone port forwarding 9332. Though I don't know that would necessarily cause any problems directly).

I've tried modifying the difficulty using this "username/xxxx+yyyy" syntax but it doesn't seem to have any effect.

All I wanted to do was reduce my share solution rate by about 1/40 of what it is right now.  I'm looking at the "u: xxx/m" field in cgminer to determine this.  It's currently showing about 120/m.

Ok... change the username being passed to p2pool.

adding "/1000" would change the minimum share difficulty you're trying to find, to diff 1000 shares. This option would be the one to slow down how fast you're finding shares. Since payouts take the target difficulty into account, finding fewer high-diff shares would pay out the same as many low-diff shares.

So, say with LTC right now, you're seeing "Share difficulty: 0.640942", and you add "/2.5" to the end of your username, you should start seeing the 'new work for worker!' lines listing your "Share difficulty: 2.500000"... if the pool diff goes higher than that, then you'll follow the pool diff, so it is whichever is higher.

adding "+0.01" would change the other difficulty. Your new work for worker is showing "Difficulty: 0.000009" for example. This is the level of work your miner is sending back to p2pool for speed calculations. If you add "+0.01" to your username, then p2pool will be asking for 0.01 diff shares back for speed stuff, instead of the dynamic one it sends.

Both of those can be used independently.

Also, there is a cap on the + that p2pool will use. I forget exactly how much, but if you set it too high, p2pool will ask for its own maximum from the miner, based on what the Share diff is at the time you start mining. This isn't much of an issue, you'd still be using a much higher miner diff than before.

Using + is _not_ a mathematical operation like the person a few posts above suggested. "+" is just a flag, same as "/", for p2pool to look for to parse out the number being passed to it, so don't use + or / in your username unless you are intending to use the options.

So...
 "/####" is target share difficulty
"+####" is target miner difficulty

Lemme know how they work out for you now.

Wishlist:
Can merged mining daemons report their getwork latency to p2pool and we can have nice graphs, like for bitcoind getwork latency?

I'm running a small GPU on p2pool (V 11.2) for mining LTC at around 145 kh/s with cgminer (V 2.11.4).  Everything seems to be working but I noticed that instead of the usual 3 shares/minute on BTC mining, I'm getting about 120 shares/minute with LTC.  Basically the shares are flying past.

Is there a way to increase the share difficulty my miner sees to slow this down?

You have 120 shares/min because p2pool-11.2 is broken for LTC stratum.  Upgrade to p2pool git.

Pretty sure 2000 is the max in the source.  I generated some 30000 difficulty share or so by modifying source.  The limit should probably be increased

Ahhhh, so that's a change beyond 11.2?  I'll update my node when I get home and try that.

[stevegee58]

I did another git clone and got the latest version and it seems to work much better.  I'm getting about 50/min now

I was having problems where cgminer would be mining away happily except I wasn't earning any LTC any more (like today).  I'll find out in a few hours if this was fixed too.  Was there a LTC hard fork I didn't know about?

[Richy_T]

OK, I don't really know much about the behind-the-scenes for mining. Are we waiting for something to happen with this one?

Also, it looks like my previous problems with p2pool synching may have been related to bitcoind eating up all my upstream bandwidth. Apparently it hadn't been an issue with any of my other stuff because I don't usually run bitcoind. I'll be re-enabling QOS and dropping 8333 in the "almost zero bandwidth" bucket.

Though I'm glad it got me to switch to CGMiner. I think it let me coax an extra 100MH/s out of my setup.

Still giving block not found. Does that mean it is not going to pay out?

from looking at my logs on nogleg,

the p2pool block was received 4 seconds after the btc guild block (14:25:22)

it got orphaned

(ed: fixed repeating myself)

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 shows when P2pool cannot connect to bitcoind, i.e. you don't have bitcoin running, or your firewall / virus program refused to allow p2pool to talk to bitcoind...  or you forgot to set JSON name/pass, re-view p2pool setup instructions.

[rav3n_pl]

Dear P2pool TRC miners, PLEASE UPADTE TRC CLINET up to 30 or current GIT!
Network is forked, current proper number of blocks is over 102`000!

hey guys, just started mining on the litefcoin p2pool and its great!

question though, I'm trying to connect to 127.0.0.1:9332/something, I login and it spits out this json error.

{"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null}

thats the only thing that shows up on the screen, am I missing something?

The litecoin p2pool network listens on port 9327, not 9332.

Using the latest release will fix this.

Is there any way to add a list of black/whitelisted IPs that can access the p2pool web interface? I know you can do it with a firewall, but i'm asking about native support. Is there any compromising info listed on that page were an untrusted party to have access to the UI?

There's not much. Arguably, it displays your public key which could be a way to tie your account to your IP and other activities. It should really only bind to localhost by default. Then, optionally, it should have a whitelist and/or require authentication. Also, it would be a good idea if it had yet another step required if it was being accessed from a public IP rather than a private one.

Are there any commands I can use to do this? I'd love to set up a user/pass system for the web UI.
