I've come to the conclusion that latency plays a huge factor in stale rate.  I think bitcoind was hogging my bandwidth, I turned off port forwarding for it, stopped using -n to connect to multiple p2pool pools, and turned off port forwarding to my backup p2pool.

After 10h 8m 45s, I have 49 shares, 2 orphaned, or 4.08% stale.  Been ages since I've been that low.

M

I found the same thing.. it is vital to keep that latency down. It makes sense when you think about it too.. if bitcoin is taking 1 second all on its own then you could expect around 10% stales just from that since we have 10s long polls.

Where in my linux p2pool directory can I look to find the human-readable version number, e.g., currently, 9.4?
run_p2pool.py --version
This was while p2pool was already running normally:
Code:
proofer@miner:~/src/p2pool$ run_p2pool.py --version
fatal: Not a git repository (or any parent up to mount parent )
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
unknown
proofer@miner:~/src/p2pool$:
The p2pool directory is renamed from the forrestv-p2pool-6880123 directory that was the expansion of the 9.4 linux tarball.
Git clone p2pool and copy data directory and use it Smiley All problems gone forever.

Excuse my noobness, but is this for Linux or Win? And how does one get this better "Git clone p2pool" - what's the procedure? I went to the site but couldn't work it out......dur.

I think it's probably easiest to just leave the folder with it's original name.  Doesn't that work?  I seem to recall someone mentioning that a few pages back.

Not if you use a script to start it.  Everytime you download a new version you have to update your script.

You could write a script smart enough to use "forrestv-p2pool-*" or if there are multiple folders matching that pattern let you pick one.

Standard "git clone" command will try to make "p2pool" directory. Version check is form git command.
To see "proper" version on windows use msysgit:
Code:
Welcome to msysGit


Run 'git help git' to display the help index.
Run 'git help <command>' to display help for specific commands.
Run '/share/msysGit/add-shortcut.tcl' to add a shortcut to msysGit.

I was seeing a v8 trying to connect during the time I was getting tons of failure messages on the shares... which shouldn't have been possible...

so, I was thinking maybe someone was trying to join wrong, with too much hashrate or something...
I have nothing to back that up tho, other than "wtf is up with this v8 node?"

Anyways, I separated my node from the rest to test a couple things out, see if I was still getting those share errors, and so far, it looks fine (except for my 2nd node not downloading shares from the 1st node)

I have seen some payouts come in on TRC recently, which I know didn't come from my nodes tho, so somewhere, I'm still getting some payout. No messages on the irc-announce tho, so dunno where they're getting inserted...

Are you still seeing errors?

I run 2nd TRC node on my machine at work, killed that raise error message about "gentx"
Looks like it is forked:

Home: Pool rate: 1.67GH/s (16% DOA+orphan) Share difficulty: 14.1
Node uptime: 0.630 days Peers: 3 out, 3 in

Work: Pool rate: 82.5MH/s (12% DOA+orphan) Share difficulty: 1.00
Node uptime: 0.005 days Peers: 5 out, 0 in

Maybe there is more subnets? Why peer seeding not work? I`ll try make more connections form my home PC when I get back (like 10/50).

I run 2nd TRC node on my machine at work, killed that raise error message about "gentx"
Looks like it is forked:
Could be forked... not sure what that v8 peer was up to, but if it was someone to just edited their v8 client to connect to TRC's network, and if they had a lot of hashrate, it could be causing problems, since the rest of us would have been considered to be switched over to v9 already...

It could also be intentional, experimenting with how p2pool could be disrupted?

The existence of that v8 peer that kept trying to connect, when terracoin network wasn't even in the client until post-v9, just keeps nagging at me... wtf is that guy up to? Why use v8 if he could have just fetched v9 to get on?

Did you isolate your nodes?

-- Smoov

edit: and another question comes to mind, with how short TRC's share chain is right now (and perhaps if a minimum # of shares in the chain should be enforced, if it isn't already)

With as few nodes as we have going right now, it is possible for nodes to be disconnected from each other long enough, to end up with the forked chains, ending up with 2 valid share chains among 2 different groups... if those 2 groups, end up somehow finding each other again, and there is no common place left in either group's chains where both chains would have diverged from, how would the clients resolve that, to allow both groups to rejoin together again?

and, could that be something that we're seeing the effects of with all those error messages, with nodes trying to resolve the shares shared by other nodes, and unable to do so?

I also got loads of 'weird' output in my trc p2pool logs, after some investigation, i found this post :

http://sourceforge.net/p/terracoin/discussion/p2pool/thread/3fe0acea/

it looks like p2pool trc settings were updated, but not yet merged into p2pool repository.

I temporarily switched to the source pointed by that post, i'll try to give some feedback after a few hours or days.

There's apparently a pull request submitted ( https://github.com/forrestv/p2pool/pull/54 ) with that code, i hope it will make it soon into p2pool repos, so my machine won't waste so much cpu/bandwidth retrying to send/receive the same shares over and over Smiley

I'll have to wait until forrestv puts together a new w32 binary... I'm not working with sources...

Sooo... I'll just keep my nodes isolated from the rest of the network until then.

And, for some reason, irc-announce isn't working either... the following block should have been in the channel.

I know it is connected to IRC, as I have all of my nodes identified. It just didn't announce.

(dunno about that block submittal result. it was a valid block and paid.)

Oh, and when you look it up on the block explorer, a curious payout to "UNKNOWN"...
> UNKNOWN: 0.00752335
> UNKNOWN: 0

dunno if that was supposed to be forrestv's skim or not. do we know if he even has TRC set up?

Does any1 mining TRC found that something is wrong? NO block in 24hrs where expected time to block is about 0.5hr?
I also got loads of 'weird' output in my trc p2pool logs, after some investigation, i found this post :
http://sourceforge.net/p/terracoin/discussion/p2pool/thread/3fe0acea/
it looks like p2pool trc settings were updated, but not yet merged into p2pool repository.
(...)
I'll have to wait until forrestv puts together a new w32 binary... I'm not working with sources...
(...)
I have merged that change in fresh p2pool installation on my bro PC and it is running w/o throwing any errors.
Will try to make exe files and put them to my skydrive.
Meanwhile if someone want to run it all form sources:
1. download python http://www.python.org/download/releases/2.7.3/ (msi install)
2. download zope http://pypi.python.org/pypi/zope.interface/4.0.2#downloads (need be unzipped)
3. download twisted http://twistedmatrix.com/trac/wiki/Downloads (msi/exe install)
4. download pywin32 http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/ (msi/exe install)
5. download msysgit http://code.google.com/p/msysgit/downloads/list (zip or exe, I prefer portable)

In msysgit shell
Code:
git clone https://github.com/forrestv/p2pool.git
cd p2pool
git remote add trcp2poolfork git://github.com/terracoin/p2pool.git
git pull trcp2poolfork master
copy data directory from old installation if want to save graphs and run it from msysgit shell (to have proper version show)
Code:
c:/python27/python.exe run_p2pool.py
or from cmd (version: unknown will show)
Code:
c:\python27\python.exe run_p2pool.py
Yes, \ and / is different Smiley

TRC shares splitting problem looks fixed.

Latest git 9.4-17-gbcda544 win32 and win64 binary on my skydrive.
TRC nodes, plz update. There is still at least 2 nodes that cant handle TRC properly and wasting a lot of data stream asking for shares over and over...
