09:30:36 <mechanic41turk[m> I am reading this: https://github.com/SChernykh/p2pool#how-to-mine-on-p2pool
09:31:29 <mechanic41turk[m> I would like to have my raspberry pi 4 (4GB) to host the monero node necessary for the p2pool. And I would like to connect my miner computer (in the same house network) to the monero node in the raspberry pi.
09:31:53 <mechanic41turk[m> Do I install `monerod` from this link? https://github.com/SChernykh/p2pool/releases/latest
09:32:17 <mechanic41turk[m> and then, does `p2pool` run on my raspberry pi?
09:32:41 <mechanic41turk[m> `xmrig` runs on my miner computer, most possibly.
09:33:02 <pauliouk> it is pushing the Pi quite a bit to get it running, but it will work. It might run a bit slow from time to time, and it will take a long time to sync up to the network
09:33:34 <pauliouk> you will also need to compile it from source as I do not believe there is a ARM binary yet (correct me if I'm wrong)
09:33:54 <sech1> yes, use p2pool-v1.1-linux-aarch64.tar.gz
09:34:24 <sech1> and monerod will most likely crash on RPi because of lack of AES support
09:34:33 <pauliouk> I should really look at the repo before commenting :P
09:35:19 <mechanic41turk[m> sech1: So, my plan is basically dead in the water?
09:35:31 <mechanic41turk[m> the only single board computer I have is raspberry pi 4.
09:35:49 <sech1> you can try to compile monerod with NO_AES option
09:36:16 <pauliouk> a backup plan would be to use p2pool on the Pi, and use xmrvsbeast[m]'s remote monerod
09:36:20 <mechanic41turk[m> compile from the source code in your p2pool repo?
09:36:25 <sech1> p2pool works on Pi
09:36:31 <sech1> I tested it on my RPi3
09:36:54 <sech1> no, you compile monerod from https://github.com/monero-project/monero/tree/release-v0.17
09:37:05 <sech1> you can use p2pool binary, it works on Pi
09:37:30 <mechanic41turk[m> sech1: I remember you said that you made a few tweaks and changes to the monerod in order for it to be compatible with p2pool
09:37:35 <sech1> and it's probably better to use remote monerod
09:37:50 <mechanic41turk[m> that's why I asked.
09:37:50 <mechanic41turk[m> sech1: ok.
09:38:10 <sech1> my changes to monerod were merged, you can use official release branch now
09:38:26 <mechanic41turk[m> very frustrating that monerod doesn't play nice with the most available single board computers out there (raspberry pi's).
09:38:28 <mechanic41turk[m> sech1: nice.
09:40:05 <mechanic41turk[m> mechanic41turk[m: I need to find some obscure ASUS single board computer with RK3399 chip and then try to import that into my country etc. etc.
09:40:32 <mechanic41turk[m> since rockpropro64's are mainly out of stock and are shipped from USA etc. etc.
09:40:38 <mechanic41turk[m> very very frustrating.
09:41:04 <mechanic41turk[m> just wanting to run a local node, requires a somewhat more specialized hardware than it is for bitcoin.
09:43:48 <pauliouk> p2pool will run ok on a RPi, the Monerod is a lot heavier on resources, so most SBC's won't handle it too smoothly
09:44:04 <pauliouk> Most of the SBC's with AES I've found only have at best 2GB of memory
09:45:05 <mechanic41turk[m> pauliouk: yes, that's what I see with one candidate for my shopping, too.
09:45:21 <mechanic41turk[m> pauliouk: you have an SBC recommendation for running a monero node?
09:45:31 <sech1> monerod runs surprisingly well on modern phones though. Just use external micro-SD card for blockchain and run pruned node
09:45:41 <sech1> Android + termux
09:45:58 <mechanic41turk[m> sech1: That would have never occurred to me.
09:46:01 <pauliouk> was just about to suggest an android phone
09:46:02 <mechanic41turk[m> Very interesting.
09:46:13 <sech1> buy old Android phone with 4 GB RAM and micro-SD slot
09:46:14 <mechanic41turk[m> I have a pixel3a running grapheneOS.
09:46:26 <pauliouk> means it's going to be stuck to just wifi, but yeah should do the trick regardless
09:46:48 <sech1> there's even official binaries for Android: https://downloads.getmonero.org/cli/monero-android-armv8-v0.17.2.3.tar.bz2
09:46:52 <mechanic41turk[m> fascinating, but still a "meh" solution to running a home node.
09:47:11 <mechanic41turk[m> a small SBC should be more stable, and more accessible via ssh than an android phone.
09:47:30 <mechanic41turk[m> since android phone runs a modified version of linux, while SBC's mainly run linux itself.
09:47:52 <mechanic41turk[m> much more accustomed to accessing linux, and doing admin stuff in them, than doing in an android phone.
09:49:08 <mechanic41turk[m> also, the phone should get really hot during initial sync with the blocks after the randomX fork.
09:49:11 <pauliouk> https://lifewire.com/run-linux-on-android-4586926
09:49:27 <mechanic41turk[m> my laptop computer always screams like crazy once monerod gets to those blocks syncing.
09:50:30 <DataHoarder> mechanic41turk[m: TL;DR compile your own binaries for raspi 4
09:50:31 <pauliouk> a little USB fan will help with things like a RPi or phone :)
09:50:46 <DataHoarder> should be fine to run a node
09:51:14 <mechanic41turk[m> sech1: also, monerod already complains about the HDD's for those having slower writing speeds. MicroSD's also have slower read/write speeds. Thus, isn't it also not good to try and run a hacky node on an android with an SDcard?
09:51:14 <DataHoarder> SD card will probably be the bottleneck there
09:51:48 <mechanic41turk[m> <sech1> "I tested it on my RPi3" <- were your RPi3 running a 64-bit OS?
09:51:52 <pauliouk> your easiest option here would be to use a remote monerod
09:52:19 <pauliouk> heck, you could probably rent a VPS somewhere for 6 months for the same price of importing tech to Turkey
09:52:46 <mechanic41turk[m> pauliouk: my goal is having the software run in the house.
09:52:48 <mechanic41turk[m> under my thumb.
09:52:57 <mechanic41turk[m> thus having the most control over it.
09:53:17 <mechanic41turk[m> at that point, why not I connect to xmrvsbeast's nde
09:53:19 <mechanic41turk[m> *node.
09:53:22 <pauliouk> always the best way, if you have a stable and quick internet connection :)
09:53:46 <pauliouk> yes the remote node is a quick and very effective solution
09:54:07 <mechanic41turk[m> pauliouk: not the best, especially the fact that my ISP doesn't give me a dedicated IP, but rather the whole neighborhood shares one.
09:54:13 <sech1> Yes, I installed 64-bit OS on my Pi
09:54:20 <mechanic41turk[m> sech1: OK.
09:55:07 <mechanic41turk[m> So, I would be installing a 64 bit Ubuntu server on my raspberry pi 4. Then I would compile monerod from the source with no AES support. And then I would download your binaries for aarch64 for the p2pool, and run p2pool and monerod on the raspberry pi 4.
09:55:15 <mechanic41turk[m> then, I would run the xmrig on my miner computer.
09:56:03 <sech1> you would get a lot of uncle shares in p2pool because of how slow Pi is
09:56:18 <sech1> it takes 200-300 ms to verify a block
09:56:21 <mechanic41turk[m> ugh
09:56:39 <mechanic41turk[m> I don't know what an uncle share is, but I feel like it is another road block to the smooth operation.
09:58:00 <sech1> you'll get lower rewards if your node is slow
09:58:57 <mechanic41turk[m> slow in the sense of read/write speeds to the SSD?
09:59:10 <mechanic41turk[m> I don't understand, the raspberry pi4 has an OK CPU.
09:59:17 <mechanic41turk[m> it's not like it is outdated or something.
09:59:36 <DataHoarder> It is slow cause of specific features randomx uses mechanic41turk[m 
09:59:50 <mechanic41turk[m> I mean, that hardware is the latest in the line of raspberry's, and if that can't handle running monerod, how can we expect "third worlders" to run a node?
09:59:59 <DataHoarder> old vs new does not mean it performs, but specific features
10:00:03 <mechanic41turk[m> DataHoarder: yeah, that was my suspicion.
10:00:07 <DataHoarder> it can handle monerod, no one said that
10:00:20 <DataHoarder> just, slower, more enough to sync
10:00:27 <DataHoarder> more than*
10:00:34 <mechanic41turk[m> DataHoarder: but it is slow, doesn't support aes, cannot run 64 bit binaries, will be slow with rewards in p2pool...
10:00:41 <DataHoarder> see, 100-200ms vs 2m interval
10:00:47 <DataHoarder> it can run 64bit
10:00:52 <DataHoarder> who said it cannot?
10:01:00 <mechanic41turk[m> DataHoarder: a sec
10:01:21 <mechanic41turk[m> See these: https://monero.stackexchange.com/questions/13265/which-download-file-should-i-use-for-setting-up-a-node-in-raspberry-pi-4?r=SearchResults&s=1|98.3441
10:01:25 <DataHoarder> I am running a monerod node on a raspi 4. Slower is not “slow forever”
10:01:33 <mechanic41turk[m> https://monero.stackexchange.com/questions/13268/how-to-resolve-the-illegal-instruction-core-dumped-error-on-raspberry-pi-4-u?r=SearchResults&s=2|90.8325
10:01:58 <mechanic41turk[m> DataHoarder: is it armv7 one?
10:02:28 <DataHoarder> They don’t say you cannot run 64-bit builds, but that 32-bit ones use armv7 and that instruction set lacks the AES ops, so it never was a problem 
10:03:04 <DataHoarder> you can make an armv8/aarch64 build for yourself that uses everything but AES hardware acceleration operations, which is what rpi4 lacks
10:03:25 <mechanic41turk[m> DataHoarder: any guides, reddit threads, etc on how to do that?
10:03:40 <DataHoarder> You could follow instructions on p2pool readme
10:04:04 <DataHoarder> Might as well build both from source :)
10:04:10 <mechanic41turk[m> seeing here: https://github.com/SChernykh/p2pool#build-instructions
10:04:41 <sech1> Slow node means you'll be mining on an old p2pool block for 200-300 longer than needed. Compare it with 10 second block time on p2pool and you'll get 2-3% uncle blocks (each uncle block gives 20% less reward)
10:04:43 <mechanic41turk[m> I don't see the build command specifying the no-AES operation
10:04:49 <sech1> *for 200-300 ms longer
10:05:05 <mechanic41turk[m> sech1: ok. thanks.
12:29:05 <mechanic41turk[m> <pauliouk> "Most of the SBC's with AES I'..." <- on this, is it recommended to have at least 4 GB RAM on an SBC, in order to run monerod?
12:31:46 <DataHoarder> you can run with less, with light-mode
12:31:49 <DataHoarder> also for p2pool
12:32:11 <DataHoarder> again, slower checking on RandomX, uses 256 MB instead of, what is it, 2 GiB?
12:34:42 <sech1> monerod always runs in light-mode when you're not mining on it
12:35:07 <sech1> it allocates 2 RandomX caches (2x256 MB = 512 MB)
12:35:17 <DataHoarder> aha
12:35:18 <sech1> p2pool does the same in light mode, so they'll take 1 GB combined
12:36:40 <sech1> So 2 GB is bare minimum to run monerod + p2pool and it will be very tight
12:36:42 <sech1> 4 GB is better
12:37:34 <mechanic41turk[m> sech1: that's good to know
12:38:14 <DataHoarder> I wonder, can I make monerod run in non-light mode, to reduce PoW check times? :>
12:38:27 <DataHoarder> probably it's just ms on this system anyhow
12:38:33 <sech1> you can start mining with 1 thread there and it'll switch to RandomX dataset mode
12:38:53 <sech1> you'll save up to 10 ms on block verification if you have 1 spare CPU core
12:39:06 <sech1> but it only works when you're mining solo in monerod
12:41:19 <DataHoarder> maybe I'll add a custom parameter 
12:44:23 <pauliouk> and remember, if you luckily mine a block solo, you have to share it with us :D
12:47:44 <DataHoarder> already shared two blocks :)
16:47:40 <sethsimmons> 35kh of p2pool hashrate is en route to me, time to step up my game and mine some Monero while providing under-floor heating to my house 😅
17:00:40 <crypto_grampy[m]> <sethsimmons> "35kh of p2pool hashrate is en..." <- Ooooo
17:00:58 <crypto_grampy[m]> Any links to a build guide?
17:01:43 <sethsimmons> No build, just old servers: https://www.ebay.com/itm/284344484287?ssPageName=STRK%3AMEBIDX%3AIT
17:02:05 <sethsimmons> Should be 6-7kh per, and I have cheap power and a great location, and obv don't need HDDs for just running Linux + XMRig.
17:04:01 <sethsimmons> Ryzen costs are so damn high right now I just went with old servers to cut CAPEX. Power usage will be much higher, of course, but if I want to stop mining for whatever reason these will make great home servers with some 2.5" SSDs.
17:14:59 <jaska087> sethsimmons: You'll probably annoy the hell out of people if you get stack of those and run them near a house :D
17:15:46 <sethsimmons> Under a house, but if the wife isn't a fan they'll get moved to the detached garage where no one will care 😀
17:16:39 <sethsimmons> I've spent many hours in datacenters so I'm well aware of sound levels to be expected with tiny 40mm fans, but I'm also going to explore building an enclosure for them all with large intake/exhaust fans and filters.
17:17:36 <jaska087> Where I currently live the heating is done with electrity only and in winter it's usually around -20 to -25C 
17:17:45 <jaska087> those would be excellent heating units
17:17:51 <jaska087> though the sound would kill me
17:18:30 <DataHoarder> min I go for nowadays is 2U sethsimmons 
17:18:47 <DataHoarder> some with horizontal pcie slots for throwing in a few 100G cards or GPUs
17:19:20 <DataHoarder> 2U, for good front 3.5" density, and large enough fans to not be 17k RPM ones
17:19:24 <jaska087> Tower/3U for me
17:19:31 <DataHoarder> yeah, it's all racked here
17:20:00 <DataHoarder> I had a 3U, replaced it, front 3.5" slot density
17:20:21 <DataHoarder> not going for toploaders either, just good density for a hyperconverged cluster setup
17:20:34 <jaska087> Had a 3U with 12bay 3'5 it was not hotswap and the cable managing, hdd replacing was a nightmare..
17:20:57 <jaska087> though it was dirt cheap
17:21:28 <sethsimmons> Understandable, main thing for me here was cost and CPUs/RAM included and fairly modern, would be easy to build a unique enclosure or use a weed growing tent (don't know the formal name lol) with forced intake/exhaust via large fans
17:21:45 <sethsimmons> I don't need the 1U FF, so can tear them down to mobo + PSU
17:22:09 <DataHoarder> yeah, here I find scrap supermicro chassi with DDR2 or DDR3 era stuff inside
17:22:17 <DataHoarder> scrap that, keep chassi for VERY cheap
17:22:33 <DataHoarder> then fill with modern things, as it's all compatible with supermicro across generations
17:22:41 <sethsimmons> Nice 😀
17:37:34 <hyc> rockpro64s are shipped from China, just like raspi
17:43:45 <hyc> at this point a phone with at least 4GB RAM is pretty ideal. has it's own built in battery backup, so it will keep working thru power outages
17:44:05 <hyc> (had one last night that knocked out my rockpro64.)
17:44:56 <hyc> I'm thinking of patching together a monerod + p2pool that outsources all randomx hashing to a 3rd process. that way only have to pay for memory once.
17:45:19 <hyc> basically using something like this https://github.com/tevador/randomx-service
17:45:32 <hyc> but with a binary protocol instead, perhaps thru a shared memory region
17:46:52 <pauliouk> hmm, about £60gbp for a 4gb unknown brand android, so like $80?
17:47:27 <hyc> sounds about right
17:47:59 <hyc> for the record, raspi 1 and 2 were 32bit only. raspi 3 had 64bit CPU but shipped with the same 32bit OS as pi 1 and 2.
17:48:07 <hyc> raspi 4 has 64bit CPU and 64bit OS
17:48:42 <hyc> you could of course get a 3rd party 64bit distro to install on your raspi 3 but raspberry didn't officially support that themselves
17:52:18 <DataHoarder> I believe modern debian works with mainline kernel
17:52:19 <pauliouk> you can also get the 64bit mod for the 32bit OS, provides 64bit support
17:53:23 <hyc> yeah, mainline kernel support is nice to see
17:54:49 <hyc> I'd also consider building a custom OS image for an old phone, that only keeps the basic linux functionality, omit the entire android runtime.
17:54:57 <hyc> would save a lot of memory
18:05:07 <pauliouk> hmm, if you can get a phone to mine XMR 2x as fast as a Pi (~200H/s) for twice the price of a pi... might be worth it to cut down on the cabling :)
18:06:14 <sech1> my 5 year old phone mines at 240 h/s. Just buy used phones
18:06:31 <pauliouk> strip the phone down, get it in a case with some airflow, granting mining on wifi isn't the best, but heck, if you can build a 1MH/s rig into a PC case cheaply, then heck time to start hammering ebay for used mobiles
18:07:35 <pauliouk> I've got an old samsung S6 with a battery thats about to go thermonuclear I could happily mess with
18:53:38 <Inge> .c 1000000/240
18:53:58 <Inge> so just over 4000 phones
18:54:06 <Inge> ezpz
18:59:59 <pauliouk> total :) why make one, when you can make 2 at twice the price? :D
19:02:39 <pauliouk> mining is only ever going to be profitable if you already have the hardware
19:03:14 <pauliouk> or if you have a collection of zero-days
20:13:12 <pauliouk> Hmm, facebook, Instagram and Whatsapp are all down... quick lets promote vaccinations, democracy and Crypto while there's no idiots around to fud it.
20:26:19 <crypto_grampy[m]> <hyc> "I'd also consider building a..." <- My body is ready
