Run cgminer as failover only

It is failover only.  That's the puzzling piece.  cgminer, sitting on the same PC as p2pool, sends anywhere from 5-20% of my traffic to the failover server.

My cgminer doesn't do that, even not set as fail over only.

My cgminer doesn't do that, even not set as fail over only.

I'm using the latest version 2.4.1, on windows 7, and windows vista.  Both setup the same way, with one 7970, and both send work to the failover servers.  It did when there were 4 gpus on it too.  I attributed it to my local p2pool not being able to supply work fast enough.  It seems to be a little better now that I have two servers, and they are forced linked together (-n), and I got port forwarding finally working so I have more than 10 connections now on my main server.  (It dawned on me my dsl modem was probably doing it, and I was right.  Once I changed it to bridged, all the sudden I'm getting incoming connections.)  But both cgminers are still sending work to the backup.  Right now the backup is reporting 222m/h, and the third backup (p2pmining.com) is reporting 62m/h. 

I have about 3g/h thrown at it, which I didn't think was that much.

Only cgminer is doing it.  My other miner is using phoenix 1.7.5 through guiminer.

I'm half tempted to remove the backups in cgminer to force them all to go to the main server.  But that PC isn't as stable as I'd like it to be yet, I want backups.

try to temprarily use my p2pool and see if it still happens. I'm running on windows server 2k8 r2 x64.

Do you have a separate router after the modem? If yes, then you are supposed to set the DSL modem to bridged, otherwise you lose lots of packets.

[kano]

Bridged means you are letting anyone on the internet at anything connected to the modem.
Non-bridged means you have to tell the modem to port forward (or set a DMZ - from a security level, effectively the same as being bridged)

Didn't lose packets, I just couldn't forward anything from the router, because unsolicited incoming connections never got there to forward.

Bridged means you are letting anyone on the internet at anything connected to the modem.
Non-bridged means you have to tell the modem to port forward (or set a DMZ - from a security level, effectively the same as being bridged)

When I initially got the modem years ago, I could not figure out how to get it working with bridged.  Not sure why, if it was on Verizon's side, or mine.  Ended up switching to DHCP, and everything worked.  Aside from port forwarding, try as I might, I couldn't get that to work.  Only recently did I realize it was either Verizon outright blocking everything, or my modem.  Fortunately it was the latter.

Yowch! - been a few P2Pool orphans lately ...

Block# -> block internal timestamp (not the exact time the block was found)
181922 -> 2012-05-28 05:28:39 (won by Deepbit)
181892 -> 2012-05-28 00:06:07 (won by Unknown)
181621 -> 2012-05-26 05:12:31 (won by Unknown)
181492 -> 2012-05-25 04:47:58 (won by Slush)

though P2Pool did win this one:
181303 -> 2012-05-23 17:53:16 (against Unknown)

So anyway, 4 in the last 3 days

I wonder if the people who made these blocks have low connection counts, poor p2pool performance or slow network connectivity from the pool to the internet?

Of course orphans are expected every so often, but 4 in the last 3 days almost suggests something else ...

[Aseras]

When a block is found is it submitted directly to bitcoind network or does it have to be approved by nodes before?

Just seems that lately p2pool is running much worse than normal variance would suggest.

On p2pool.info, how does one find the address that associates with your wallet? It was pretty easy for me to find myself on there given how there are only 3 users at 10 GH/s but holy cow that would be a nightmare trying to figure out which address was mine if I was in the 1 GH/s range. I believe p2pool outputs the receiving address when you start it up but I don't have my p2pool client accessible at the moment. I do however have a copy of the wallet that I monitor daily, which was how I was able to track block payments to figure out which was me.

If you using default bitcoin client from gavin, then you can click on transactions tab & select a particular transaction & double clicking it will show transaction details which show the amount received & also transaction id.
By searching http://blockexplorer.com/ on transaction id, you can see which address it got coins, from which address....

Convoluted but makes sense. Much appreciated.

OK, after 1/2 years of p2pool mining I finally quit.

Simply because I don't get the reward I should get.

When I look at the luck chart it's always around 90%. And that pretty much confirms my own (long term!) observations: When using p2pool I get only about 80-90% of the reward I get compared to Slush or Deepbit.

Question: Is there any chance that p2pool will finally be able to compete with the other pools? Or is the p2pool approach simply inherently flawed?

I'm assuming you're letting p2pool auto-pick an address for you instead of just telling it what address you want it to use.  If so, then when p2pool starts up, it displays the payment address it auto-picked for you.

Answer: Not if its hashrate drops by the day. Seems counter-intuitive to me... Trying to reduce variance problems by lowering the hashrate of the pool. 

I'd love to switch and get more BTC, but it's the idea behind the pool that's important to me.

[Gomeler]

Err. Any reason why the pool has lost nearly 100 GH/s in the last day? Not a huge issue so long as we continue to find blocks and achieve roughly 90-95% PPS.
