This is a guide on how to run P2Pool on Ubuntu 16.04 LTS Server with merged mining (emercoin)

17-May-2017: 1st version - Please report any issues

IMPORTANT SECURITY NOTE: If you are running your server on a VPS with full internet access make sure you change the rpcpassword or edit your config files and add rpcallowip=127.0.0.1

Some history:
I created this guide to have up to date P2Pool installation instructions on latest version of Ubuntu LTS (currently 14.04).
People may consider it difficult to get a P2Pool node up and running but in fact it's very simple if you have some basic Linux knowledge.
In this guide I will provide BTC and merged mining.
Note that althought BTC mining is distributed among P2Pool miners, merged coins will not be distributed to others but you will solo mine those.
If you mine exclusively with P2Pool you will get the same profit (and a bit more) compared to mining to other pools. In the long run NMC/DVC/IXC profit will be the same.

Install Ubuntu 16.04 LTS Server from here: http://www.ubuntu.com/download/server
(note do not install Ubuntu DESKTOP 16.04 LTS - you need Server version for text only install)

I will not cover instructions on how to do this. You can install it in a virtual machine or a physical machine.
For virtual machine start with 2 Processors and 4GB memory. Suggested disk size is 300GB (that's a lot but you will have room to grow).

Create a user and run all the commands as a user NOT as root.

If you find any mistakes please let me know!

First thing after you install ubuntu is to install all updates and prerequisites for Ubuntu:

Grab P2Pool:

Setup Bitcoin config file:

About emercoin:
We have already emercoin binary already from official repo.
For each installation a random RPC password is generated so do a:
sudo cat /var/lib/emc/.emercoin/emercoin.conf
Find the line:
rpcpassword=PheIHyBs99yyTBgrQGa6mUMmmO8Tq3ht

And hold on to this password.

Don't just copy paste the lines below.
Change the password after emccoinrpc to match your password you got above:
For example it should be: --merged http://emccoinrpc:PheIHyBs99yyTBgrQGa6mUMmmO8Tq3ht@127.0.0.1:6662/


You are not ready to start P2Pool just yet. The BTC blockchain has to be downloaded first and it will take some time...
So execute these commands and wait...


Run this command to start P2Pool:

You can view the P2Pool ouput using

You disconnect from the P2Pool output by pressing: Ctrl-A and then D (nothing will show on screen)

When you reboot your server you can just start it by executing:
~/start-p2pool

The above command includes a wait of 200 seconds (so that bitcoind gets latest updates) before starting p2pool.

Making a new guide for Ubuntu 16.04 and Emercoin merged mining.
If there are any other coins that are not dead and can be merged mined please let me know so that I include them.

Καλημέρα παιδιά,

επειδή το node δεν χρησιμοποιείται από κόσμο (εκτός από έναν) και εγώ δεν κάνω mining (προς το παρόν), θα κλείσω το node.

Παρακαλώ μεταφερθείτε σε άλλο p2pool node ή άλλο pool

Thanks!

kapetanιο να σου πω τυχαία τι συνέβη σήμερα.

χτυπάει το σταθερό σπίτι και μου βγαίνει ένα αυτόματο μήνυμα που μου λέει ότι έχω κερδίσει ένα ταξίδι κλπ και να πατήσω το 1.

Πατάω το 1 μόνο και μόνο για να μάθω ποιος είναι αυτός που παρανομεί.
Ρωτάω που βρήκατε το τηλέφωνο; Μου λέει δεν ξέρω που κάλεσα - το σύστημα καλεί τυχαία νούμερα. Σε ενημερώνω ότι αυτό απαγορεύεται εαν δεν το γνωρίζεις.
Ρωτάω πως λέγεται η εταιρία και μου λέει ένα όνομα κουκουρούκου που δεν κατάλαβα τι ήταν.
Της λεω πες μου το ΑΦΜ της εταιρίας και μου λέει - εσείς έτσι δίνετε το ΑΦΜ σας και μου το κλείνει.

Τα ΑΦΜ των εταιριών καθώς τα συνδεδεμένα στοιχεία (διεύθυνση, τηλέφωνο) δεν είναι κάτι που είναι απόρρητο για μια εταιρία σοβαρή.
Υπάρχει κιόλας εφαρμογή και API του υπουργείου οικονομικών που βάζεις το ΑΦΜ και σου λέει τα πλήρη στοιχεία της εταιρίας.

Δηλαδή εαν πάρω εγώ τον ΟΤΕ και του πω δώσε μου το ΑΦΜ σου θα μου πει είναι απόρρητο; Δεν μπορώ να κάνω κάτι εγώ με το ΑΦΜ του άλλου - πέρα από το να διασταυρώσω ότι αυτός είναι πραγματικά.

Τώρα όσο αφορά την coinbase να στείλω mailάκι εαν θέλεις να ρωτήσω σε ποια χωρά είναι registered και το VAT τους. Εαν αρνηθούν να το δώσουν και αυτοί τότε μακρυά.

Πάμε τώρα στο πρακτικό. Με όποιον συναλλάσσεσαι πρέπει να ξέρεις πως τον λένε και τα πλήρη στοιχεία του. Βάλε μου 50 BTC σε μια διεύθυνση που θα σου δώσω και θα φτιάξω μια ωραία σελίδα και θα σου δώσω πίσω 200 σε 2 ημέρες π.χ. Δεν το κάνεις. Γιατί; Γιατί δεν έχεις καμία κάλυψη. Όταν θα πας στο δικηγόρο το πρώτο πράγμα που θα σου πει είναι να του κάνουμε μήνυση/αγωγή κλπ.
Θα σου πει ποια είναι η εταιρία; Θα του πεις έχει ένα website (που μπορεί και να έχει κλείσει). Σου ζητάει ΑΦΜ ή όνομα εταιρίας για να το ψάξει μετά αυτός. Εαν έχεις όνομα εταιρίας είναι άχρηστο. Η εταιρία μπορεί να λέγεται Foufoutos.com αλλά πραγματικά το ΑΦΜ να ανήκει στην "Παπαδάοπουλος εξόρυξη νομισμάτων ΕΠΕ". Άρα τι θα βρει ο δικηγόρος; Τίποτα...

Both are sold!

I haven't received any response from the "2 winners".

Hence I have to call this auction as FAIL and proceed to a new post.

As you can see the auction has now closed.

I need help from the moderators how to handle this as I have two people with the same offers.

Since this is closing tonight I just wanted to post the valid offers:

I remind everyone that shipping is NOT included in these offers.

monkeynutts: $1600
ThEmporium: $1600

If this is correct please post proper posts as you guys have same offer.

Thanks!

Hey guys,

I'm getting offers via PM and I want this to be a fair auction.
So if you are serious about your offer please post it publicly.

People are asking me about the shipping cost.
This depends on the country of course.

Here are the dimensions of each box:
Dimensions: 63 *56 *14 cm
Weight: 14kg
Country/Postcode that courier will pick up from: 15341, Athens, Greece

So please do check locally how much it will cost. I can get a quote as well from UPS. Supposedly I have good prices with them but I have found out that they have screwed me over before.
So if you get a quote and I get a better price we can use my price, otherwise we use yours.

Καλώς ήρθες στον κόσμο του bitcoin.

Όπως θα μάθεις κανένας δεν τηρεί τις ημερομηνίες

Thanks for the offer Oldbones.

My idea is that these miners should stay with one owner.
They grew up together in the same rack so I don't want to split them up

About consumption - here is the official page:
http://www.spondoolies-tech.com/products/sp10-dawson-mid-june-batch

It says 1050W (up to 1200W). I don't have something to measure it at the wall unfortunately. Maybe other owners of SP10 have done it already.

Live monitor (I use this for people to check it when they rent it through betarigs):
http://pool.nitro.gr/sp10/

In temperature is about 24C.

For anyone interested i'm selling my 2xSP10s:
https://bitcointalk.org/index.php?topic=783559.0

I have 2 Spondoolies Tech SP10 that I'm putting up for auction.
I have the original boxes for both of them and the miners are located in Greece with customs cleared and paid for EU.
So if I ship them to EU then you don't have to pay any extra taxes.
I will use the original boxes to ship them to the winner as soon as on Monday 22-Sep-2014 (that is next business day after auction has ended and payment has cleared/escrowed).
There are no cables / mount ears included.

This will be an auction that will end 19-Sep-2014 @ 22:00 GMT.


Both of the miners have been mining without issues at eligius, p2pool and I rent them at betarigs (https://www.betarigs.com/rig/7601).

One of the miners has minor cosmetic damage but hashes without issues.
I have no problem accepting escrow using a reputable member of bitcointalk that offers this service.

Description: Spondoolies Tech SP - 2 pcs
Starting bid: $1600 for both of the miners
End date and time: 19-Sep-2014 @ 22:00 GMT
Payment methods accepted: Bitcoin, Paypal, Bank Transfer
Shipping cost NOT included

I'm providing pictures of the miners.

This is the first miner:


This is the second miner with the cosmetic damage:




Happy to answer any other questions.

Updated namecoind and huntercoind.

namecoind issues with merge coin mining are fixed.

So how is Matt's fork running guys?

I wanted to ask if Matt's fork is lifting the issue of having to use low latency connections for P2Pool.

Yes no problem with that.
Thing is that in 12 months time - even in 3 months time a miner of 1TH/s might be useless to run at home/datacenter.
And where can I buy a new one from?
So in other words who needs an excellent working P2Pool when nobody will have miners at their homes making ROI.

The manufacturers are taking away the benefits we have with P2Pool with forcing cloud mining only (and by forcing I mean if they sell to us miners that will never ROI).

On a side note this answers the fact why they switched S3 to preorders.
I don't know if this is good news or bad news - as this leaves only Spondoolies to offer hardware without running a farm at the same time.
Yes you will say that Bitmain is "renting" its power but since they come out and say that they officially have a farm we don't know how much extra power (maybe the S3s that didn't ship for 1.5 months) and of course they are merge mining.

So is this good for p2pool? Well nobody will care in 12 months time because it seems that we will all be forced to switch to cloud mining and others will keep the benefits of p2pool. We will just get payouts based on a calculator every week.

It seems that serious companies copied pbmining's ponzi scheme. But this time since they have their own hardware they will just remove the "ponzi" part and do it legit and we will all accept and be happy.

It seems mining for the average folks will be a thing of the past soon...

And now everyone starts thinking that maybe forrestv is working for bitmain on the new branch thats why he had disappeared?
