You need to get the vertcoin p2pool code. Sorry I'm on mobile or I would post a link. Google will get you to the proper github fork for scrypt-n p2pool. Also, I'm pretty sure that fork already has settings for gpucoin. Good luck.
Hi all! I am trying to start a p2pool for GPUCoin, got a lot father that i thought i might on the first night! self teaching and doing this on a linux vps.
I am getting this error when launching the run_p2pool.py:
Would love to figure out what i am doing wrong. Thanks for the help!

Hi,
I am trying to set up p2pool mining for the new crypto money called CrimeaCoin.
I tried connecting miners (CGMiner and SGminer) from my local computer and I am getting these error messages:
1. Locally:
2. On the server I am getting the following:
I am stuck with this error message "Handshake timed out, disconnecting from". Tried searching on Internet but nothing helpful.
My code is
p2pool/p2pool/networks.py
p2pool/p2pool/bitcoin/networks.py
Does anybody know what is wrong? I will appreciate any help. Thanks!

This alone of course yields LateEnd errors anytime work comes in with transactions due to the extra field (tx comment).
That error points to the unpack function in p2pool/util/pack.py where as already discussed in this thread, we can set ignore_trailing to True. If we do that in both places it is set to False, p2pool will accept and work on blocks with transactions, but fails when trying to submit the solved block with -
I played around in helper.py with the submit function to no avail, so instead I went after the transaction format (realizing full well that this might break coins that do not have a transaction comment, including possibly the merged coins I am working on, but if I can get it working *with* comments, I can then figure out how to make it deal with stuff without comments) -

and this of lead me to the EarlyEnd in my previous post. I also tried ('txcomment', pack.PossiblyNoneType(2**32 - 1, pack.IntType(256))), which lead to the same.
I did try a varstrtype for txcomment but that lead to some strange errors -
I realize it's a string in the grandcoin code, but I'm guessing and hoping it's converted to something else before it's sent over, if it's not I may be barking up the wrong tree though. I also tried PossiblyNoneType/VarStrType and got the same AssertionError.
Any help, tips, pointers, code, genie wishes used towards this, online python tutorials, or anything else that could be of use would be GREATLY appreciated!

I realize it's a string in the grandcoin code, but I'm guessing and hoping it's converted to something else before it's sent over, if it's not I may be barking up the wrong tree though. I also tried PossiblyNoneType/VarStrType and got the same AssertionError.
Any help, tips, pointers, code, genie wishes used towards this, online python tutorials, or anything else that could be of use would be GREATLY appreciated!
ok, I think I've got it looking for a comment now by modifying the transaction stuff in p2pool/data.py and p2pool/bitcoin/data.py, but now I'm getting EarlyEnd, I'm guessing when there isn't a comment present -
This I am not sure how to deal with. If there are any python ninjas out there that could point me in the right direction that would be great.

This I am not sure how to deal with. If there are any python ninjas out there that could point me in the right direction that would be great.
I've recently tried to port p2pool to some newer alt coins and have been hitting a brick wall. I'm pretty sure this going beyond basic network.py values but I wanted to get some opinions.
I've tried setting this up for grandcoin, lottocoin, luckycoin and earthcoin. The one I'm most interested in getting to work is earthcoin, so let's take that one for example. This is the error I receive when running it.
Now, what I noticed is in the pack.py file, the functions
is where the error is being thrown. The pos is always 1 character bigger then len(data) when the error is thrown. So setting the ignore_trailing=True eliminates the error, but when testing it against earthcoin, we hashed overnight and found a few blocks. However, none of them were actually committed to the blockchain and nothing was paid out. So I assume that is messing with the blocks submitted and they're not valid.
If you don't change that variable, the error that was mentioned is thrown for a while. Eventually it will connect to the wallet daemon, and you can actually hash in the pool, however the connection to the wallet will go unstable and the errors will start again. The connection to the wallet never really stabilizes.
Just for reference here are my earthcoin network.py values.
If anyone that has better python skills than me, and a better knowledge of how p2pool works cares to help, I'd greatly appreciate it. Like I said, I don't think this is isolated to earthcoin as I've seen this behavior with several new alt coins. Also, I've posted a bug report on the official p2pool github in case anyone wants to contribute.

Anyone have any updates/more information on this? The bug report hasn't been updated in quite a while it appears. I recall reading somewhere (probably this thread) that it has something to do with transaction comments in some coins. I tried setting ignore_trailing to True as mentioned above, and that resolves my "Error getting work from bitcoind" errors, and p2pool will accept and work on block with transactions, but when they're solved it is unable to submit them ...

It retries a few times and then gives up. I've switched back to solo mining right off the wallet (so, no merged
) until I can figure this out, but I don't know where to begin, and half a day of reading everything I could find online hasn't yielded a solution 
I just immediately reconnect when that happens. Have not had to use + anything but then again I have 5 Mh/s so it may be adjusting higher faster for me so when I reconnect the pseudo diff is already primed to be higher.
The danger is like the guy who replied here
https://github.com/forrestv/p2pool/issues/183
You probably recognize him from irc.
If he falls over to a backup pool then much later back to his own node, it might do nothing but HWs all day until he can manually fix it because of the 0 diff issue.
Perhaps using cgwatcher can help. Not sure (haven't looked) but it may have a setting to watch for # of HW errors and restart the miner. If not then maybe we can make a feature suggestion.

If he falls over to a backup pool then much later back to his own node, it might do nothing but HWs all day until he can manually fix it because of the 0 diff issue. When you first connect to a new node and there are no stats at all you will get served DIFF 0 work which will cause HWs in some types of miners. If you mine for a while with any + it will get some stats stored, then you can disconnect and reconnect without the + and you should be fine, with vardiff giving you pseudoshare targets above 0. I just put in a suggestion to the p2pool repo that the minimum work ever served should be 1 (for sha256) or 1/X where X is the scrypt adjustment to the difficulty figure for that coin (it's in bitcoin/networks.py).

Q1) Can someone let me know how to get the Prefix and the Identifier for a new coin? (specifically litebar)
Added it to my guide..it is also here earlier in this thread.
Thank you for that!
This is what happens when I run it - I get all Succcesses at the top but then I get this repeatedly:
2014-02-25 19:31:06.817362 P2Pool: 0 shares in chain (0 verified/0 total) Peers: 0 (0 incoming)
2014-02-25 19:31:06.817451 Local: 0H/s in last 0.0 seconds Local dead on arrival:
Expected time to share: Any ideas?
EDIT: Its works I think, I just pointed my miner at it. I'm getting a bunch of HW issues but I'll sort that out.
When I tried starting a Litecoin p2pool earlier I wasnt getting the above messages that I am getting with Litebar. Not sure why.
Right I have this kinda working, finally.
I was getting a bunch of hardware issues until I put +16 after my username in my cgminer conf file. However I dont think this is the permanent solution. I think its a setting on the server that needs to be corrected to may be allocate the difficulty better. I think its one (or more) of the settings to do with ~/P2Pool/P2Pool/Network.py
I will tweak them, however if anyone has any ideas on which ones I should be fiddling around with, please let me know.
Muchos gracias amigos.

Q2) I have done the settings (except for prefix and identifier) to the best of my ability with the aid of this thread for Litebar network.py in both P2Pool locations. Can some bright spark actually post the correct settings for Litebar please. I have spent 12 hours trying figuring it out and could use any help.
I know some of these settings are ball park figures, and some of these setting might be completely wrong. Any help would be appreciated. Thanks

I know some of these settings are ball park figures, and some of these setting might be completely wrong. Any help would be appreciated. Thanks
Thank you all for this useful thread!
But I found if use p2pool setup by myself the HW error is very high from the output of CGMiner.

I can say I have seen this several times myself, unfortunately not 100% sure the cause of it quite yet and has not happened everytime so have not found the pattern yet.
Have seen this happen on the first miner to join a node. I forget the exact message but also notice something like "unidentified stratum" in the console when this happens.
Simple quick fix (for me) is to restart the miner.

Someone say getting work with 0 diff causes errors but I have no idea if it is HW errors or something else. Try connecting to your node with /.00001+.00001 if you use a scrypt based coin. (/1+1 if a SHA based coin). That will make sure you never get anything below 1 diff.

Started a new thread detailing the values. Work in progress. Will update as time allows:

SUBSIDY_FUNC = *
pulled from ./src/main.cpp (search for "nSubsidy")
total number of minable coins.
I believe this is incorrect. I think the correct way is:
for litecoin:
SUBSIDY_FUNC=lambda height: 50*100000000 >> (height + 1)//840000,
SUBSIDY_FUNC=lambda height: 'block reward' * 'satoshies' >> (height + 1)//'height where block halves'.
If there is no "halfing" you take out the >> (height + 1)//'height where block halves'
//840000 is the number from main.cpp in nSubsidy -> nSubsidy >>= (nHeight /
Thank you! I have updated my post to reflect your corrections.
IMHO the main problem with this is, that p2pool tries to dish out share difficulties so that it expects no more than one solved share per minute from all connected clients. So as my VTC node has about 6 MH/s local rate at the moment, the log shows a standard share difficulty of 1.39 given to clients. Minimum share difficulty for the pool is 0.063 on the other hand. So it seems perfectly legit to specify a custom share difficulty of 0.55 for my miner. (If you specify it too low, p2pool seems to use the minimum pool difficulty anyway).
Interesting. I kept assuming small miner variance was due to large share difficulty but that's not the case at all for VTC right now, if you are a small miner using a big public node.

I have a couple dozen lines similar to the first. The 2nd is my testing with difficultly forced as low as it can go. Being a single GPU miner, 1.5 (98683) will take me far far longer to get 1 share than .058 (3805) would.
Edit: Apologies for the thread hijack. mmouse we should move this to the P2Pool main thread or to the VTC thread.
