How often does p2pool query namecoind getblockaux? I would like to make sure the namecoind internal recalculation time step makes sense.

Just grabbed the new version, working perfectly.  Also adding -Xmx my virt mem went from 11GB down to 2GB usage, so I'm a happy camper.

Great work Matt!


Hey guys, running windows 8.0 Bitcoin core and my p2pool node.
Is there anyway for me to get this all up and running with this sort of setup?
I cant figure out how you guys are doing this.

Must I be running lenox?

Any info would be much much appreciated....
Thanks.

You should be able to download the latest Java JRE from Oracle, then run the same command:

Code:
java -Xmx100m -jar DRIVE:\PATH\TO\RelayNodeClient.jar public.YOURRELAYREGION.relay.mattcorallo.com 127.0.0.1:8333

I'm not a Windows user, so I might have a minor detail wrong, but Java is cross-platform and works on many operating systems.

Great question.  I'll look into the code to see if I can find the answer for you.  If somebody happens to know this off the top of your head, please respond to phelix.

Three simple steps:
1) Go to http://www.java.com and download and install the executable installer for your platform.  You only need the JRE, not the full JDK.
2) Open a cmd prompt (I think it's now powershell in Win8?) and navigate to the "bin" subdirectory where java installed itself.
3) Execute the same commandline as above.

Now, there are enhancements you can do to this, namely putting it into a batch file and running it in the background (i.e. as a service) so that it will run without needing the powershell window open all the time.  However since I'm not a windows guy you'll have to do some research on the best way to achieve that.

But, those 3 steps should get you up and running quickly for now.

Thanks windpath for the fast reply! but now I have another noob question... i can reload bitcoind bitcoin.conf without restart p2pool and loose incoming connection? E

You can, obviously you may miss out on a share during the restart. Your bitcoin peer connections will be lost, but p2pool peers will stay, here is what to expect:

p2pool will throw the following error while it can not reach Bitcoind

Code:
Failure: twisted.internet.error.ConnectionRefusedError: Connection was refused by other side: 61: Connection refused.

If the bitcoin restart takes more then a minute this message displays in the log and front end:

Code:
> ########################################
> Warning: LOST CONTACT WITH BITCOIND for 1.0 minutes! Check that it isn't frozen or dead!
> ########################################

Laptop?

I would guess your issue is with the hard drive - although it's 7200RPM, it is only a single drive.  You might be better served by replacing it with an SSD, since the local blockchain transactions are disk intensive.

Also, what O/S?  If it's Windows you also might benefit from more than 4GB RAM as well.

CPU should be plenty tho.

ok and thanks for the reply, so if I understand it, restart your bitcoin wallet does not create any problem (apart from losing a share if it happens at the time of the reboot)

is an experimental configuration to see if it works, surely if all goes well I will invest some money in a faster computer.

The HD is 7200rpm, but I'm going to replace it with a ssd

Operating system is openSUSE linux, cpu utilization varies between 20% and 70%, I have 4 gb of ram in total and by now they are only used 2.6

Correct, you'll just chance losing a share if it were to happen during your restart.  Otherwise no worries.  I have done it multiple times where I just restart bitcoind without touching P2Pool and it recovers nicely.

Ok, that sounds fine.  I'm thinking the disk will really help with the GBT.  1s is not good, but it's workable for now especially if you're just testing it and have plans for something beefier later.  I would just caution you that if you are running the wallet on the same "server" you take plenty of backups... with only a single drive if it goes you'll lose everything if you don't have backups.

And, I would also suggest that if you are planning on opening your node to be public (and possible even if not), if you have the resources, run your wallet on a totally different machine.  This way if something bad were to happen (hack)  your wallet won't be compromised.

Right, good idea! I'll do a daily auto-backup on a usb stick. Just copy the folder "data" or is it better that I do I copy the whole folder directly "p2p-master"?

With regard to the possibility that something bad happens :-(  I made start the pool with the option "--address" which, as far I understand, it sends the payout of the pool to another address different than the wallet of the pool. is that right?
This idea, however, I hold in consideration because surely could raise a bit of work to my poor toshiba...

I had think a laptop was sufficient to run the p2pool because I noticed that system requirements not too exorbitant, also consumes much less power than a standard desktop, the only thing I regret is not having put a ssd .. .

I hope and I plan it can become a public node, because in Italy there are few p2pool and with a very high ping, but for first I want to fix this glitch ... thanks to all for the help. Erik

I would STRONGLY recommend against keeping any private keys on the pool machine.

Old School P2Poolers...

I reached out to Forrest V for this, but in case he does not reply, or misses a key point; I'm working on putting together a brief history of P2Pool milestones for inclusion in the new P2Pool.org site (launching soon!).

The current planned format is a timeline, so if you know of a key P2Pool milestone/event you remember from the past please share it here so I can include it in the new site...

Question for running Matt's RelayNodeClient:  Do I have to do anything special from my bitcoind conf side (other than the usual RPC credentials stuff), or is the setup just running the jar with the right params?  So far it looks like the Relay is working correctly, but I want to make sure it's feeding my bitcoind as needed.  I already have a few choice addnode listings.
