Which one is more performant between data=writeback vs no journal?

mawk: I need performance for fast synchronization on monero blockchain LMDB.

I'm also going to mine.

WARNING net.p2p.tx src/cryptonote_protocol/levin_notify.cpp:680 Unable to send transaction(s) to tor - no suitable outbound connections at height 227468

What does it mean?

Such I am, Very I am

Is this room being infiltrated by chat bots?

Monero telegram channel was already infiltrated by at least one chat bot and several psy-op agents.

infiltrated? no

no idea what that warning is

if it works then AIUI you can ignore

oh tor

no idea

mycorrhizae[m]: what do those qr codes do

They are recieve wallets

For corresponding coin

I assume the person who made it put them there

btrfs isn't fast with `noatime,nodatacow,nodatasum,compress=no,space_cache=v2`.

If I used LMDB on raw disk, will I still know how much free space is left on HDD?

* If I used LMDB on raw disk, would I still know how much free space is left on HDD?

How can I make monerod co-operate with logrotate? monerod doesn't tell me any process signal that it accepts.

fatcat[m], monero has its own built in logrotate

monerodocs.org/interacting/monerod-reference says

> In production deployments, you would probably prefer to use established solutions like logrotate instead. In that case, set --max-log-file-size=0 to prevent monerod from managing the log files.

gingeropolous: ^^

What is a good value for `db-sync-mode`?

The documentation for `db-sync-mode` is very outdated.

ah yes re: logrotate. I dunno. I use to use logrotate on monerod just fine until the built in thing was implemented, and then i just used that

so i dunno. re: db-sync-mode, i think the default is generally fine.

other options are useful if you have a system that likes to crash and doesn't keep its file system safe.

thats why i think with windows the option safest is used or something

fuck windows, use linux!

gingeropolous: I searched reddit and read monero codebase. It turns out that safe mode is turned on if monerod is within a few blocks of the latest block and is turned off when it's not synchronized.

ah nice.

But, it is not documented.

your really diving in.

can you help document it as you go?

Maybe...

maybe...... yes!

I doubt that monero is going to accept a new pull request since it has a lot of pull requests waiting to be merged.

dude, if its documentation thats like frosting on a donut.

no that makes no sense

my point is that it can't break things

ad there's always pull requests waiting to be merged

don't let that get in the way of progress

don't let progress get in the way of progress. new saying. trademark.

Okay

Which one is faster for monero blockchain synchronization on HDD? btrfs without checksums, compression, and copy-on-write? ext4 without journaling?

Seems fun.

How do you think of tokenzed stocks on ethereum blockchain?

tokineko[m] ext4 manual seems to imply that data=writeback offers the most throughput

data is written directly to disk

and journal is later updated for metadata

because I'm not sure what you call no journal

I don't see any option to disable it

or rather, the only option I see is data=writeback

it makes data skip journal

journal is only used for metadata, asynchronously presumably

fatcat[m]: I'd do pruning

if I were you

fatcat[m] are you tokineko[m] ?

you have the exact same question

pruning + regular ext4 should be good enough, or maybe data=writeback but I'm not convinced it will offer the highest speedups

given the risks

Yes, I am.

mawk: You can create ext4 with `-O ^has_journal`.

mawk: monerdo automatically switches to safe sync when it's synchronized to the latest blocks.

* mawk: monerod automatically switches to safe sync when it's synchronized to the latest blocks.

good then

pruning will give you the biggest speedups

can you mine with pruning though?

yes

use that then

thanks

How much difference in performance is there between`data=ordered` and no ext4 journal?

I guess there's a lot.

btrfs without copy-on-write doesn't seem slower than ext4.

raid6.com.au/posts/fs_ext4_external_journal says `journal_async_commit` increases ext4 performance.

hi there, i need some help. had a few transactions from a pool be sent, i see them on the chain but dont see them in my wallet =(

edlou, is your wallet fully synced?

Mochi101: i have been trying to use remote node

Sometimes some remote nodes are stuck... try adding one manually... you can use a reputable node like node.xmr.to or node.supportxmr.com

is monero-wallet-cli --ademon-address node:ip correct?

ive been trying supportxmr but get error message connecting

trick questions... hold on...

yes --daemon-address:port

i get this message and it hangs:

Warning: using an untrusted daemon at node.supportxmr.com

Using a third party daemon can be detrimental to your security and privacy

it hangs?

It might take a bit but it should get through.

ok let me try again i keep closing terminal after a minute

You can also try adding --trusted-daemon

will the cli wallet have to do the refresh every time i start it?

no

well... if you exit nicely it won't

will it cache something somehow or how will this work? i just assumed the remotte node would be instant

(honestly scared somehow my keys were compromised) dying to check....

it'll cache your wallet

Why are you scared that your keys were compromised?

i tried the appimage for mymonero , saw balance of 0 , but also no history, just very worried

looks like it will take maybe an hour or more to finish refreshing, i hope im not a goner, thanks for helping me guys

😭

Good luck.

Don't use mymonero.

people will keep using it so long as it's on the getmonero website

does anyone here use edge wallet?

never used it

but somebody i told to have a look at the website decided to use it because ot its multi currency capabilities

CLI wallet best wallet

Mochi101: true

but for mobile users

I used the GUI wallet for some time... but after ~1000 tx history it was impossible to use... So I stopped using it... The history thing was supposedly fixed but I just never went back to it.

Well, for mobile I use Monerujo

same

but a lot of n00bs like the multi coin wallets

Just a testing thing though... not for any real use.

i'd never heard fo edge before yesterday

just want to make sure it isn't a pile of poop

also don't want to dissuade somebody from using something out of pure ignorance

That's how I found the bug that you could crash Monerujo by using a colon in the tx-description field of a qr code

Fixed now though.

People who lose XMR tend to use mymonero.

Is defragmentation bad for LMDB?

`btrfs defrag`.

vikrants[m]: Any plans for HW wallet support in Cake?

* `btrfs filesystem defragment`.

Yes it’s on the list. But other things are taking priority.

Fair. It looks nice now.

I guess I may use xfs rather than ext4 on my HDD. Xfs is faster than ext4.

btfs ftw

*btrfs

Sync is stuck at Height: 1351184/2293005 (58.9%) on mainnet for more than an hour. What is going on?

Perhaps, I need more RAM with `block-sync-size=100`?

`free -m` tells me I'm not running out of RAM.

Check the output of "sync_info".

If you're not sure how to interpret it, paste it on some paste site.

It's partial, right ?

yes

set_log 1, then wait a bit, see if you have verification errors.

Ah, then it looks like it's failing to get the next it of data it needs.

It's been requested, it should time out.

In much less than an hour.

pastebin.com/KkeNnApU is the log.

moneromooo: ^^

Can you get another with log level 1,*queue*:DEBUG,net.cn:DEBUG please ?

Maybe 10 seconds' worth.

Can you give me an exact command?

set_log 1,*queue*:DEBUG,net.cn:DEBUG

moneromooo: pastebin.com/FYwBD4zQ

I'm synchronizing to become a full node.

Perhaps, there are malicious nodes that prevent me from synchronizing?

you can use --enable-dns-blocklist to block malicious nodes, but you should still be able to sync fine without it

Can you PM me your external IP address, I'll check my node for logs. Looks like you're requeting objects but never getting them.

So peers seem to be rejecting your queries for some reason.

You're requesting blocks from several peers, so it's unlikely to be bad peers.

So, all of them configured their nodes wrong?

Unlikely, it';s probably your node that's wrong.

Try restarting with: --add-exclusive-node 88.198.163.90:18080 (that's my node, so I'll have logs from the other side)

Ah, crap, my node is pruned where you need blocks.

moneromooo: pastebin.com/9jKKWmPQ is my current config. I pass --data-dir=/data/monero --non-interactive to monerod.

What does --add-exlcusive-node do exactly?

It uses only that node as a peer.

Oh, try removing --block-sync-size as a test.

100 is fine normally, but yo umight be hitting large blocks...

It'll normally use 20 there.

According to `free -m`, I'm not running out of RAM.

whats your full list of startup flags?

Checking the code, there's no size limit there, still worth a try I guess.

What the hell. It started synchronizing again without `block-sync-size=100`.

`block-sync-size=100` must have overwhelmed something in monerod.

nice find

I suspect `block-sycn-size=100` surpassed `block-download-max-size`.

ah. im trying to reproduce. whats full startup flags?

monerod --data-dir=/data/monero --non-interactive --config-file pastebin.com/9jKKWmPQ

i don't see block download max size

oh that wasn't a startup flag

?

I've been trying to connect to all the remote nodes listed on moneroworld.com from my tails gui wallet. but it just spins for a while and says network status disconnected. no info in logs panel.

gingeropolous: I didn't include `block-download-max-size` in my config or startup flag.

multifractal, try a node like node.xmr.to or node.supportxmr.com

add it manually\

multifractal: you have to connect to an onion node

i used note.xmr.to yesterday and it worked fine

gingeropolous: I use monero 0.17.1.9

i tried an onion address too, and same thing

both node.xmr.to:18081 and node.supportxmr.com:18081 are online

i tried both of those

block-download-max-size is unrelated.

there is no further information in the logs

It's more likely to be a packet size limit.

matrix.org was awfully slow and disconnected frequently on tor browser. But, matrix.monero.social is quite fast on tor browser.

did you activate socks5 proxy in settings -> interface?

moneromooo: What kind of packet?

Remote nodes that aren't yours shed some privacy, opens some more avenues of attack, and make the network less resilient compared to running your own node.

Network packet.

Monero network packet.

Can I adjust the size of monero network packet? Or, does monerod have to be modified?

You'd modify monero, but you could not modify peers'.

moneromooo, is this related to recent modifications?

Slice blocks up.

i feel like i remember something about size of things being modded recently to mitigate stuffs

I think `block-sync-size` should be renamed to `max-block-sync-size` so that blocks fit in monero network packets.

`block-sync-size=100` shouldn't block synchronization.

what is the default value?

`block-sync-size=100` before v4. `block-sync-size=20` since v4.

block-sync-size automatically adapts if I don't specify it manually.

I only tested the recent DoS mitigation patches with default value.

`--block-sync-size` // How many blocks are processed in a single batch during chain synchronization. By default this is 20 blocks for newer history and 100 blocks for older history ("pre v4"). Default behavior is represented by value 0. Intuitively, the more resources you have, the bigger batch size you may want to try out. Example:

`./monerod --block-sync-size=500`

yesterday i used node.xmr.to:18081 successfully. now nothing connects

multifractal, have you tried to run monerod and get your own node going?

running a node on tails is complicated

i don't have disk space for that

did you see my message?

13:39 <selsta> did you activate socks5 proxy in settings -> interface?

selsta: that box is ticked

I'm feeling the temptation to run a pruned node as I watch the synchronization.

multifractal, have you considered renting a vps to run your own node and then connect to that from your tails setup

the problem is not the node

node.xmr.to is online

xmr.to is out of business by the way.

its online but is it connectable

my main remote node currently has 100 rpc connections

thats when it starts to be useless

gingeropolous: yes it is online and connects fine

i've tried a whole bunch of them

is there any way to get more detailed logging of the failure

fatcat[m]: yes, but the node will continue to run for now

> Sad news today. With heavy hearts we are announcing that the XMR.to service will no longer be operated.

multifractal: can you start monero-gui from the tails terminal?

selsta, gotcha

then it will print logs, you can also try to increase log level if nothing useful shows

Some problems at connecy, mssage: connection refused

By the way, you can still use xchange.me as a substitute for xmr.to

Or, fixedfloat.com

yeah we gotta get something in cake soon

to replace xmrto

I set log level to 4 in the GUI and I'm watching the console

"Connection refused" is all I see in the way of errors

By the way, monero-gui should decouple monero.

* By the way, monero-gui should be decoupled from monero. monero-gui should depend on monero as a dynamic library.

"regex not matched for URI..." - some kind of warning maybe?

maybe i'll just come back in a few hours and see if magic fixed it

less than ideal but i'm out of ideas

Does Anyone know some DEX which trades Monero with low fees even for about $ 50k ?

By the way, monerod is not really pushing HDD, CPU, or RAM, but synchronization is slow.

freenode_yunes[m]: Have you tried xchange.me or fixedfloat.com ?

50k is a lot...

You can also try polarity exchange.

You can always use the existing exchange in Cake wallet to convert xmr to btc a bulk amount and save the btc in your cake wallet and use it when you need to.

Polarity Exchange has a centralied order book, but it is a non-custodial exchange.

* Polarity Exchange has a centralized order book, but it is a non-custodial exchange.

<fatcat[m] "You can also try polarity exchan"> is it DEX or centralized?

It's somewhere between CEX and DEX.

No I need a DEX only

Look into BTDex and turtle network DEX.

By the way, you don't need an account on polarity exchange. You can create a local account and save the seed.

You can also use it on tor browser.

It is also non-custodial.

* By the way, you don't need an online account on polarity exchange. You can create a local account and save the seed.

O javem

* I haven't seen a true DEX with some liquidity.

Bisq exchange is also a true DEX, but it is slow and doesn't have a lot of liquidity.

Verus coin tries to be its own decentralized exchange at the protocol level.

You can convert wrapped XMR into pirate chain or verus coin on verus coin desktop wallet.

* You will soon be able to convert wrapped XMR into pirate chain or verus coin on verus coin desktop wallet.

<yunes[m] "No I need a DEX only"> Satisfied?

fatcat[m]: do you use a HDD?

Yes, I do.

A 6TB HDD

* A 6TB HDD dedicated to monero blockchain.

afaik the problem is HDD read latency

SSD will result in way faster sync

monerod isn't really pushing HDD throughput.

* monerod isn't really pushing the limits of HDD throughput.

like I said, the bottleneck is read latency

It's random seeks, not throughput.

Reading 400KB/s doesn't really push an HDD.

Okay

How can I improve read latency?

Copy the chain to RAM or use a SSD.

HDD is fine if you are okay with initial sync taking longer

Catting to /dev/null caches to RAM IIRC.

hahahaha.... I don't have 6TB RAM.

The chain's only ~30 GB pruned, or 100 GB unpruned.

You likely have only a portion of it as of yet.

Ethereum blockchain is already 6TB.

:|

I have 16GB RAM.

Is xfs going to decrease read latency?

Disabling checksum, copy-on-write, and compression improved write on HDD.

* Disabling checksum, copy-on-write, and compression on btrfs improved write.

According to benchmarks, xfs is the king of speed.

hello good day

I'm translating zero to monero to portuguese.

But, there is not much difference in random read between xfs and btrfs.

Next time, I will buy a much quicker storage.....

so i have a question : on page 38 it's incorrect because it's small k and not K . That bob needs to sign with. Bob does not sign at any rate with his one time address!

UkoeHB: ^

he proves ownership by signing with his private key small k one time...

I guess...

So as i am translating this such that i understand it. I hit a bump right now.

2TB SSD is surprisingly affordable.... Damn...

fatcat[m]: once you are synced it should not matter too much, though SSD will be faster when generating a transaction

on chapter six, it is said that a MLSAG will be used for each Rj.

slave_blocker: UkoeHB is the author, maybe he can clarify

Is there such a thing as trusted raw blockchain that I can import?

yes, if you created it yourself on a different device

but not from the internet

but a MLSAG includes all the one time public keys in it's construction...

That's not very comforting since I turned off checksumming...

Can monerod verify database corruption?

* Can monerod detect database corruption?

are you using monero-blockchain-import or monerod?

I'm using monerod to slowly sync for now.

Can monero-blockchain-import detect corruptions?

there is ./monerod --db-salvage that can fix corruptions, but obviously not guaranteed

Does btrfs copy-on-write degrade LMDB write performance significantly?

I don’t know.

Without copy-on-write, I don't get checksums. Without checksums, I can't easily verify corruptions.

It seems I may look for a way to get checksums without copy-on-write.

* I may look for a way to get checksums without copy-on-write.

<fatcat[m] "By the way, monerod is not reall"> is fixedfloat DEX?

freenode_yunes[m]: It's a CEX, but it's also non-custodial.

It's non-KYC.

You don't need an account on fixedfloat.com

The object packet size limit is 128 MB, which is more than the current overall limit at ~100 MB, so it's not that.

The 100 blocks from the log add up to ~34 MB.

moneromooo: maybe objects / fields / string limit?

though I think we did it so that a ~10x growth would be fine

As I said, my node's pruned there.

Is yours ?

New idea for reducing MineXMRs hashrate (currently 40% of the network): old.reddit.com/r/Monero/comments/lg…er_distribute_moneros_hashrate_away

Hi, can anyone recommend how to buy smaller amounts of monero safely ? im kinda new to cryptos in gerneral, preferably a way i can use Exodus as a wallet and without the chance of being scammed

ktwo, localmonero.co or kraken.com might be good options

ComplyLast Thanks

you're welcome

how long will my tx show pool 'locked'?

Should be 10 blocks.

moneromooo, I think I asked you this before but I can't 100% remember. If I run a pruned node and make it a public node is it handicapped at all?

Not really.

The one thing it cannot do is send back unpruned historical block/txes, but wallets don't ask for that.

Is it only the post RingCT blocks that've been pruned?

I think so. Can't recall for sure now.

I'm asking because like it or not storage is still fairly expensive and I want to keep my costs under control but I want to run a public node.

Ah, yes. rct only.

ok

It's possible to prune more, but the node would be less useful to others on P2P.

I have both a pruned chain and a full chain locally... if I copy the chain and prune it again it'll be different than my other pruned chain right?

Probably.

ok

It might pick the same eigth to prune. Probably won't.

s/prune/keep/

I see lately that the community really has a need for 'trusted' public nodes... I usually recommend node.xmr.to and node.supportxmr.com... would be nice if I could recommend my own.

home connection Mochi101 ?

make sure you don't have any data caps if thats the case

gingeropolous, yeah but... stupid setup that doesn't allow me to open up an incoming connection

ah so your public node will be ... on a vps?

yeah

but I heard that sometimes there are problems with crashing when you run a node... so I want to keep it separate from my other site

Can anything be done with a wallet file password without having access to the wallet file?

Nothing but smartarse replies.

leonardus, not really... but you might want to transfer your funds to a different wallet just in case.

I was asking because I found a Monero entry in my password manager from 1-2 years ago but I think I only had a few dollars worth in it so it's no big deal if I can't recover it

If it's a set of 24 or 25 words, it's enough to restore the wallet. If just a password, nope.

ah oh well then

maybe it's on one of my old hard drives I'll have to plug those in

hiya!

total noob at using monero

installed the wallet last night and transfered my money out of binance

it still hasnt arrived.

whats that about?

Is your daemon done syncing ?

"status" will show.

says its fully synced

Is your wallet done scanning ? "status" will also show.

wallet and daemon both synced

Is the wallet monero-wallet-cli ?

i have no idea

downloaded the simple one from the monero page

using it with a ledger

Type "set", what is the value of "refresh-from-block-height".

in the log?

On the console output.

yeah i have the gui wallet

What does it say in Settings -> Info under wallet mode?

2293269

wallet mode

simple

That's the refresh from block height ?

ok and under wallet restore height?

2293269 (change)

hmm did you change that number?

nope

That's *really* recent.

As in, a few minutes ago.

i only set it up last night

try clicking on change and setting it to 2293000

and then on ok twice

wait for it to refresh and your funds should show up

Maybe the wallet estimation is getting worse now. I'll check.

gui has its own estimation code

Oh. OK.

(why ?)

though it was a JS port of the same algorithm

so they should be the same

<moneromooo "That's *really* recent."> How can you say that? A formula or smth?

its just sitting spinning on closing wallet. it did this last night now i remember

worst case you can simply recreate the ledger wallet

though changing it should also work if you wait a bit

<selsta "github.com/monero-projec"> Thanks^^

It seems to be a couple days off only.

Ejderha[m]: yes, formula if the deamon isn't online.

perfect. thanks very much. makes sense. so my wallet was backing up from a point after the transaction was procesed?

yes

gotcha. cheers. would never have got there myself

Amazing people out here eh

so did it work again?

its still closing wallet but im hopeful. you sound like you know what your talking about

:)

that closing wallet thing should not take that long, worst case close the gui, reopen and restore your ledger wallet from height 2293000

paste.debian.net/hidden/839b337e seems appropriate (not even built yet).

have to restart.. ffs.

I just hope everything will be alright when back

2293000

thats what my refresh height should be?

You want that to be a bit before the heiht when you sent that tx. 720 blocks per day.

When did you send it ?

last night

So... 2292000 should be safe.

xxx3000 would be too high, most likely.

There it is!

thanks guys

sorted.

thought id made a right mess of that cause when you press copy address button to receive, it copies over "monero:" with it

which you then have to manually delete

and i thought i may have deleted to many characters

i had to do that cause when i scanne dthe QR code it was saying it wasnt a valid address

Possibly because it has "monero:" in it.

im assuming cause it was taking that extra bit over with it too

It's meant to trigger some URI scheme demultiplexer somewhere.,

defeats the point of having a QR code in the wallet though does it not?

if its taking over invalid addresses?

It's not an address, it's a URI.

With the address in it.

Now, I'm not sure what you were copying exactly.

when i click on the receive thing

it gives me threeoptions

for the QR code

and the primary address is sitting above it

with a copy to clipboard thing

so the QR code doesnt work when i scan it with binance

ignore me

ive just done it again

it didnt bring the monero: thing across

it must have still been in my clipboard from when i copied the QR code

last night

anywho. all sorted now. thanks for your help guys

selsta: does the GUI also have a month off for safety ?

If the daemon is not reachable, it does this in wallet2. And if it's reachable, it would not have had a height that high yesterday.

Unless it's generated when connected to some asshole ofc.

When generating a new wallet without daemon, I get 2269xxx here, which is nowhere near Kenalda's value.

(with monero-wallet-cli though)

my strange number may have been something to do with the wallet not shutting down correctly last night. so when i opened it up this evening it was the high value as selsta said was a couple of minutes ago

?

i only installed it last night so techincally it would never have ran correctly

It's generated when you create the wallet. Not shutting down correctly would not cause this.

ahh

well its as well you can change it manually then!

Did you have the daemon running when you created that wallet ?

you want me to creat another wallet and see what it says now?

Sure.

i was having a fair few problems as i had ledger live running at the same time and my ledger was pinging between the two of them

2272000

That's good.

although i created my other wallet from my ledger

which was where i had the problems

Not sure why it'd matter, but if this is the only difference, it might be that.

2272873 if i create a new wallet from the ledger again.

who knows. seems to be grand now

Alright, thanks for testing.

no bother. thanks for sorting it

see yas later

I think everyone here knows that most Monero exchange withdrawals and desposits are traceable (Breaking Monero - poisoned outputs). How does it feel to go out and lie to people that they are private and then earn less than holding BTC on your bag?
