P2pool feathercoin linux

[gwbraa]

Wellenreite Can you tell me How Can I not connect to the other nodes?
I will set upt a dedicated server and I wanna try run the 200MH/S for some couple hours and I do not want to get everyone not making shares because I am to fast.
Also How can I setup a hostname for the p2pool server??

Thanks

Not sure what you mean, your miners cannot connect to other p2pool nodes, or yoir node cannot connect to other p2pool nodes?

In order to set up a nodename for your node, that is known to the Internert, you need to register a domain and then create a DNS Record for the host. There is a small monthly fee for the domain.

With your bandwidth of 200 Mhash, you always will find block so fast, that other nodes have difficulty to submit valid shares before your miner finds a new block.

A possible solution:

• go for solo mining with most of your hash power and only keep a hashrate comparable to the hasrate other miners provide or may be double it. This will increase the diffculty of the blockchain, but the p2pool will keep the share difficulty low, so others can submit shares to the p2pool nodes.

Re causing large swings in the p2pool difficulty :

I don’t think there will be a problem (at that scale). I received shares for a much lower proportion of the p2pool with both Bitcoin and Litecoin mining.

We have also monitored 10 - 50 MHash/s variations in p2pool, which the p2pool algorithm handled no problem …

In practice what will happen with p2pool if the hash rate goes up, the Global pool members will get more payouts, but a lower rate. When there are few miners / hash, it pays out less often, but higher … The p2pool share system is quite effective at adjusting as the global hash rate changes.

plus we can always monitor the situation, if you let us know when you are testing…

It is theoretically (and practically) possible to make different “colours” of p2pool pools. It is possible to adjust some parameters, so that the p2pool will only connect to a similar compiled pool. This means it would be possible to gave a p2pool adjusted for lots of small hash miners, with lower shares more often, and different coloured pool optimised for high hashing rates, but say short periods (like weekends).

Unfortunately, that sort of facility is not built into p2pool yet, although you can experiment, as it’s open source.

I was thinking it was possible to config my p2pool to do not connect to the other nodes, so I would be mining like solo???

About the hostname I already have domains. I already setup one for the machine but I was wondering with in the p2pool I would be able to set the name for the hostname as well.

Yeah around this number I did not had any problem

You are correct, you can mine “solo” - even if your p2pool node does not find others pools, it is connected to the Feathercoin blockchain via a different port.
We have had the situation where p2pool nodes loose contact and the pool continues alone - so you could iptables/firewall, the known other node’s IP address, to deliberately prevent connection to a global pool.

you can use the -getpeerinfo switch with feathercoind to see who’s connected.

So you can find shares, then feathercoind will announce when you found a block and your p2pool will pay you.

[Wellenreiter]

@wrapper the problem occurs, when blocks are found by the pool so fast, that small miners can’t submit a valid share, before a work restart is requested by the pool.

Yesterday, we had the situation, that blocks where found by the pool about every 10-30 seconds, while miners with hashrates of ~100-150 khash only could send valid shares only every 3-4 Minutes.
The result was, that small miners didn’t get any payout.
This situation is temporary, of course, as the block chain difficulty will go up until blocks are found every minute again, but still such a situation is not encouraging small miners to mine on a p2pool.

I dont know if you have tried manually setting your miner’s diff but this seems to help me out on p2pool:
-o stratum+tcp://104.236.34.9:19327 -O 6e3ozu798fKvNUCSwRjPMRdnrJ27dCHEPm/0+0.00300:lol

The “0+0.00300” seems to do a decent job of lowering stale % for me

The p2pool node initially needs at least one other p2pool node to start.
When this initial connection is lost later, it may continue to work.

Yes I forgot that, another adjustment needed to implement coloured pools would be solo mining capability. Or set up two p2pools on the local network / in containers - as a work around.

That is a good way for larger miners to tune their share difficulty and reduce the negative influence on smaller miners.
I have released a new branch of p2pool software -adaptive- which does this automatically. it adjusts the individual share difficulty so that all miners submit shares about 2 times per minute.

For pool operators:

• https://github.com/wellenreiter01/p2pool-neoscrypt branch ‘adaptive’
• on the command line specify the parameter ‘-d A’ to enable adaptive share diffculty

@RIPPEDDRAGON : The adjustment you did is still possible with the new software, of course. It overrides the automatic adaption.

ftc.siweb.co:19327

This will be the final version!!
I will try to keep alive this node for as much I can. I will be putting some hash power as well.
Let’s see the results in one month
How Can I know the number of blocks discovered by the node?

There is no direct way to find that, although you can look at the explorer, this is a p2pool block :

http://explorer.feathercoin.com/block/0ccf2ac81e3cfe01fbd004fd2886e2c8e30748f232eae1b76dcb7e5da09a0aa9

you just need to use a separate address for each node, then see what comes into the wallet.

I thought you had added the adaptive difficulty into the master branch, which is what my pool is built on. I’ll have to update to this and try it out.

The p2pool it’s amazing for this pool http://p2pool.neoscrypt.de/
The weird thing this wallet xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx you cannot even see their balance but their taking a nice cut with only 600K
I will keep watching this, but smells something weird. can you guys check this pool and this wallet

It was on the master branch vor p2pool Version 13.X already, but it got lost during the upgrade of code to version 15.
I added it again now.

Just a couple of points.
FTC is not a bank, we cannot check out pools or addresses.
There is no “smells” around FTC p2pool, it has been run and updated as an open source project virtually since it’s inception.
There is a limit on how many transactions Bitcoin-Abe can show, so addresses that have done a lot of mining show a message “too many blocks to display”, which is a “bug/issue” with Bitcoin-abe not FTC …
I have edited the Address, to prevent a FTC miner being falsely accused of “smells”

Oh ok. Is there a table or something you can post to give us a rough idea what the settings would be at a specific hash rate? Even with setting difficulty manually on my address, i still get a lot of tiny payments. Id be happy with fewer, large payments - even so much as being paid every other day or so - if possible.

[Wellenreiter]

@AmDD there is a difference between the number of payouts and the number of times that shares are submitted to the pool.

You can’t influence the frequency of payouts in a p2pool, as it doesn’t store or collect coins for later payouts. whenever a block is found the 80 FTC in that block are payed out directly to the miners, according to the percentage of work they submitted to find that block.

The adaption mode or the manual difficulty adjustment only influence the frequency the miner submits shares back to the pool.

Basically faster miners get allocated larger pieces of work, so they have more to calculate before they sent back the work and get new work assigned.
In theory a miner only needs to send back work once in a round to get payed for a found block.
The automatic adaption adjusts the work, so that miners submit sares back to the pool every 30 seconds to make sure that miners have submitted work, even if the pool finds several blocks in a row.
