I'm having a problem with my node when trying to set it to become public and open port 18089

When I use my external ip for the rpc bind I'm getting 2 errors

2020-06-14 00:17:52.726 F Error starting server: Failed to bind IPv4 (set to required)

2020-06-14 00:17:52.768 E Exception in main! Failed to initialize core RPC server.

it then shuts down

when I use my internal ip the daemon will start normally and work fine but I am not able to connect to it with any wallet

Here are the settings I am using to start it --restricted-rpc --rpc-bind-ip 111.111.111.111 --rpc-bind-port 18089 --confirm-external-bind --public-node --rpc-payment-address 49wNldksjfakldjfkladjfkladjsfklj --rpc-payment-credits 250 --rpc-payment-difficulty 1000

what settings you use in router ?

i'm port forwarding 18080 and 18089

do you specify the Ip from your machine ?

yes im using the external ip from my machine that i use to host a webpage and other nodes

I need to set it like external port X ( if needed to Ip ) to internal port Y on internal Ip

not running a public node now, didn't play with it already, waiting on a good server..

got disconnected there

can anyone here me?

Is the "blob" in the get_block RPC function enough to reconstruct a block? If not, what is it missing?

I know with Bitcoin you can request entire raw blocks via RPC.

I'm working on a project similar to kryptoradio but for Monero.

If I sent only the blobs from the get_block RPC function, could a receiver build the blockchain?

Depends what you mean by block. If you want the actual transactions, you need to request them separately (except the coinbase, which is already present).

I'm trying to get raw binary data for a full block like the result that Bitcoin's getblock RPC function returns when verbosity is 0.

This is the Bitcoin RPC function I'm trying to find for Monero. bitcoin-rpc.github.io/en/doc/0.17.99/rpc/blockchain/getblock

blob is the raw binary data for the block. It has transaction hashes.

It seems too small to hold actual transactions.

Is it small because there are only coinbase transactions?

It it small because it has the coinbase tx and transaction hashes. A transaction hash is a 32 byte value that identifies the tx, not the actual tx (which as I said you need to request separately).

(should you need them)

So if I understand correctly, the coinbase tx is the only one included by default?

I'm trying to put together a full block that a receiver can receive, verify, and add to its blockchain.

Correct.

Then you need to request the txes from the tx hashes included in the block.

You don't have to parse the blob btw, they're also included in the json IIRC.

There's a method called get_transactions that I can use.

When I have all the transactions from a block in hex format, how do I know how to arrange them in the right order so they hash to the right block hash?

Sorry if that's a very basic question.

You want to have a blockchain built up from RPC, rather than P2P messages ?

Yes

The tx hashes you get will be in the right order.

(from get_block)

Thank you, that makes sense. I guess I would assemble a block with a header after that and it would be the same as the one in the data file.

Depending on what you call header. If you have the blob from get_block and all the tx blobs the block references, you have all you need.

That sounds easy.

Thank you for explaining it.

Hi all, what's the difference between the --p2p-bind-port switch and the --p2p-external-port switch for monerod?

Steven_M: both are explained here: monerodocs.org/interacting/monerod-reference

selsta: ahh, I see :-)

The percentages in this message seem contradictory: "(99%, 186 left, 64% of total synced..."

Steven_M: It means 64% of when you started syncing.

selsta: ahh, thank you. :-)

it would be easier for home computers to run a public _tor_ node, right? no requirements to open ports, which is more of an effort typically?

"The daemon allows to make a node public by simply adding the flag --public-node. Doing so, it will be advertised on the P2P network and people will be able to connect to it" @ web.getmonero.org/resources/moneropedia/remote-node.html - advertised how? above this is 'aggregators' which are manually and central, there's no 'p2p list' of public nodes is there? we have to use the likes of moneroworld.com/#nodes ?

azy: moneroworld.com uses a script to find all of the nodes that have port 18089 open and working. --public-node does what it says it does, you don't need to ask moneroworld, just other nodes on the network

Advertised by setting the relevant flag in the peers list that nodes share.

#NoFlagIsIrrelevant

oh man... wrong channel

:)

asymptotically, im not seeing such a list, i just see a couple manually entered nodes with no up(time) checking

where are you looking? i think that there's a command to print them all in the daemon cli

if i were looking for a public node to connect to i'd go to moneroworld.com/#nodes

"TOR Remote Nodes Note - I don't check these, at all. No idea if they work..."

i wanted to automate this

for regular nodes too, but i dont know if thats necessary

azy, ^^^

neat

There will be so much bash it won't be funny.

Can I somehow limit the ram usage of monerod. I know that lmdb should free up space when other processes need it, but I m having a weird bug on my pool where im getting errors after few days of running it...

Try looking into cgroups.

xmrpow: how do you start monerod? systemd service?

asymptotically: Im just using screen ./monerod and few other arguements

xmrpow: have a look at github.com/monero-project/monero/bl…aster/utils/systemd/monerod.service and freedesktop.org/software/systemd/man/systemd.resource-control.html (tl;dr: add MemoryMax=1234M)

thanks ill have a look.

then it can automatically restart it for you when it crashes and at boot. much nicer than running it in screen :)

asymptotically: Is there a way to reattach to monerod in order to use monerod command line?

asymptotically: systemd was a great hint!

no way to reattach

selsta: But how can I check if everything is running fine?

e.g. ./monerod status

or use tmux or whatever

selsta: If I detached monerod i cant use the command line of monerod

Did you try it?

ops sorry. Does work.

Thank you

cd

Can't wait for the Monero project to move to radicle.

I think maybe Tari and radicle would be compatible.

They could do the blockchain stuff on Tari.

probably.

i dont know
