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

[lenny_]

P2pool becomes incompatible with some miners. Even with Stratum mining-proxy itself!
Look at Ztex BTCMiner log:

Code:

001-0: ztex_ufm1_15y1-04A3461AD9-3: Error: unknown protocol: localhost: Disabling URL localhost:9332 for 60s

It cannot connect to p2pool and switching to backup pool
Stratum-mining-proxy reports:

And it's not working, miner connected to this stratum-mining-proxy cannot get any work (proxy spits out thousands of errors) and switching to backup pool.
With new version 10, P2pool become unusable for both miners I am using - Ztex BTCMiner and Stratum mining proxy.

Both BTCMiner (v121126, cluster mode) and BFGminer seem work well with p2pool Stratum for me,
I don't see the same error for BTCMiner, running on amd64 Linux,
do you use different version or platform?

BTCMiner does not have any Stratum support, only GetWork+ var diff. How it can be working for you, mate? 
I am using same as you AMD64 Linux.

Haha..I just mean the version of p2pool with Stratum support
But maybe I don't run BTCMiner long enough to see the error.

Luke jr, I thought you were anti stratum last I checked

[Luke-Jr]

Luke jr, I thought you were anti stratum last I checked

I'm anti-stratum for the pool<->miner connection, because it is* harmful to Bitcoin's security. In this case, the p2pool daemon is running locally, so it makes sense. (It also makes more work for me, and slush did it behind closed doors instead of contributing to the open developement of GBT)

* slush added a get_transactions method to allow for more transparent stratum use, but in this usage, it just consumes more bandwidth than GBT with none of the benefits

Gotcha

Can you at least back up those lies?

1) How is stratum harmful to bitcoin's security in any way that GBT isn't also therefore harmful by your definition in their current incarnations?

2) Why does someone have to contribute to the development of GBT when they have their own idea that was known and in the open since the beginning of the year?

3) What is this new lie you are now spreading about comparing GBT to Stratum and saying that the Stratum transaction list is in any way less meaningful than the GBT transaction list and in any way uses more bandwidth?

Seriously, you lie about this all the time and never back up your lies coz they are simply that: lies.

Backup your bullshit or shut the fuck up about this crap you keep lying about all over the place.

Yes I know you wont follow this up and give any proof to your lies, coz they are simply that - lies - as everyone should understand that they are.

something wrong with ur bitcoind

I upgraded to the stratum enabled p2pool & cgminer but had to turn stratum off due to massive rise in stale/rejects, even after lowering my intensity on both Linux & windoze rigs - anyone else having these problems?

well then just use getwork, unless u got more than 50 GH/s it dosnt need stratum

Recompiled to latest git and restarted, will see.
Nothing wrong i see in bitcoin log anyway.

Done. Much better results. I was of the understanding that stratum was going to be an improvement ie: less stales/DOA?

a share being orphaned means it dosnt fit the rules (did include wrong transactions, etc) or just really unlucky. therefore something wrong with ur bitcoind, restart it. i found that using the latest git is working well, but u shouldnt mine to a address in the wallet of the git bitcoind since its not declared stable yet. i got a VM running with every altcoin in it and bitcoind, p2pool is connecting to this and payout is set to another adress.

it should yes, altough if there are problems (since its new and therefore probably bit buggy) u can get worse performance. im running cminer too and i got 0.36% stale, all my shares have been accepted (due to alot of connections) so far with stratum enabled.

I had to disable stratum here as well, higher rejects with stratum than with LP.

Interesting indeed. I'm running cgminer/p2pool with Stratum and am not having the issues you and others are mentioning. My reject rate is 2.3% and is the same as it was when I was running getwork. I still show Zero stales on Stratum as I did on getwork as well.

p2pool and bitcoind are running on a local server on my LAN. My rigs communicate with them on that same LAN/subnet.
 
I do not use the un-released git version of bitcoind.

If you are using an un-released git version of bitcoind or are using a non local p2pool server that could be your problem.
