[Dev] Feathercoin - P2Pool-Neoscrypt - Now Available

Wellenreiter

I’m orking on the problem.

Setting Persist to False in networks.py , starting the pool and setting it back to True solves the problem in most cases.

After the pool has run for some time, it should be able to start also with persist= True.

Current problems:

stats page shows wrong time for found blocks. Display: 2 weeks ago, while chain explorer shows soe hours ago
pool nodes are not fully syncing
network hash rate shown is too high.

Wellenreiter

Update:

I restarted the pools at p2pool.neoscrypt.de (46.4.0.101) and pool20.neoscrypt.de (95.85.57.10) from scratch.

Both pools are synced now.

I connected from a third instance to the p2pool cloud and got connected and synced within seconds.

Please try the following:

modify networks.py and extend the bootstrap_addrs line :

BOOTSTRAP_ADDRS=‘atlas.phoenixcoin.org prometheus.phoenixcoin.org p2pool.neoscrypt.de pool20.neoscrypt.de’.split(’ '),
set the Persist entry to ‘True’
delete/move the data directory from the p2pool directory tree
start p2pool without the -n parameter you may have used

I also updated Github to reflect the new networks.py. No other changes in todays commit.

Wellenreiter, is your GitHub code up to date? It produces incorrect targets like before:

   },

By the way, midstate and hash1 are deprecated. I’ve removed them already from my P2Pool. data may be reduced to 80 bytes.

ghostlander

One more thing. Your today’s commit added 192.168.0.113 to bootstraps. This is a gray IP of your LAN.

Wellenreiter

Oh sorry,

that one was for testing.

thought, that I removed it.

It’s fixed now.

p2pool-neoscrypt

This is the latest P2Pool with NeoScrypt. Supports Phoenixcoin and Feathercoin. It needs patching in order to provide miners with correct targets, etc.

lizhi

I had updated from wellenreiter01’s code. Now PXC-P2Pool work normal . I can mine blocks. :)

In addition, I think the OpenCL kernel may fix some problems. I had mined pxc in p2pool about 3 hours, No HW error.

Start phoenixcoin daemon :
phoenixcoind -daemon -debug 

Start pxc-p2pool:
python run_p2pool.py --net phoenixcoin  --bitcoind-p2p-port 9555 --bitcoind-rpc-port 9554 p2pool PoAzL52WzHRJovA6kZkptwVTdX9xMxPkwi

Start cgminer.exe with stratum:
cgminer.exe --neoscrypt --worksize 256,256,256 --thread-concurrency 8960,8960,4000 -I 13,13,12 -g 1 -o stratum+tcp://pool.ftc-c.com:11554 -u PfF9PKBjkmz7gFAkA7h6ajY5AHc9B1mijW -p x

lizhi

FTC(testnet)-P2Pool work normal too. :)

ghostlander

Both my or Wellenreiter’s code behaves the same if you start on the PXC testnet with PERSIST=False and no shares in the P2Pool chain. The share difficulty is very low and incorrect. Maybe it becomes correct later when the chain grows up, but it’s better to have it correct right from the start.

darksaber

Looks like mine is working now for PXC. Downloaded the shares right away. You can check out my node here: http://104.131.5.165:10554.

Thanks!

Wellenreiter

Yes, your node is connectred and synced.

I can see it in the peer list od the other nodes

lizhi

My share may be wrong, But I get PXC normal , some hashrate not display in p2pool.

Wellenreiter

did you delete the data directory and restart the pool?

The display of your last but one posts shows also a wrong list of shares found. Compare to the list on p2pool.neoscrypt.de and pool20.neoscrypt.de

It seems your data directory is corupted.

ghostlander

I have launched atlas, prometheus and menoetius again. Getwork and Stratum work fine. They don’t join your existing nodes due to code differences.

ghostlander

My P2Pool source code is ghostlander/p2pool-neoscrypt

I suggest you either to update your nodes or move to a different prefix, because there are share conflicts. My nodes generate shares every 30 seconds to minimise stales, your nodes produce them every 15 seconds.

Wellenreiter

I will move to 30 secs time to share

ghostlander

I will move to 30 secs time to share

Can you connect to my nodes now? I’ve also updated SANE_TARGET_RANGE = (2**256 - 1 >> 30, 2**256 - 1 >> 12), but these are for Getwork. Stratum uses DUMB_SCRYPT_DIFF = 2**16

darksaber

I have tried both new versions (ghostlander’s & wellenreiter’s) and I am back to not being able to download shares again. If I copy my old data directory over I can get it running, though it’s split brained.

You need to clean up your data directory first. Make sure you have PERSIST = True set.

darksaber

Yep, id that. PERSIST = True. Here is an exert from the log:
