Topic: Advice on Raspberry pi hardware for running full BTC node - page 3. (Read 3198 times)

Some (very very few but some) routers have the Wi-Fi and hard wired networks separate.
It's supposed to be some form of "security"
Make sure that there is no obscure setting somewhere in the router to keep them separate. I have not seen it in a while but there were a few that did it.

Must be something with the router, Tried with my laptop which works over wifi but does not work over any of the eth ports. I'll call support.

you can confirm this by using the ethernet port of a device that you know is working over wifi, as the other possibility is that the image file you downloaded is broken somehow

tbh, you're better off with Raspbian, as the maximum number of people will know how to help you (Raspbian is probably most popular OS image for Raspis, whereas this myNode software most certainly isn't)

Tried that, only 6 devices including the router.  None besides the router return a web UI.
My router does not display any details to devices that I can see, possible I'm not looking in the right place though. Now messing around with nmap (zenmap) but not sure how to use it really.
I've even reflashed the memory card to make sure it wasn't corrupted.
Sigh...
Edit: I'm thinking it may have something to do with the router. Shows wireless devices but not wired devices.

Ok, I've got the ethernet cable connected from the router but I can't find the device using the advanced IP scanner.   I can see the router and other devices such as phones and computers on the wifi network but not the device connected to the eth port.   What am I missing here?  I have access to the router login creds but cant seem to locate any device info there. I can see packets being sent and received on the eth port, just can't find the ip address of the Pi.  Using windows
Have Zenmap but not sure how to use it

Probably but there are a bunch of full nodes on the lan that it is on so it might just be sucking it down quickly.
It's a decent machine with SSDs so I'm not sure how it was pulling it. Quick mode shows error now so I don't know if was or not without going through the logs.

What philipma1957 said.
Use a cable not Wi-Fi
There is 1 driver that would have to come with it to use the wired nic since all of of them are the same.
There are many more Wi-Fi drivers that would need to be setup if you wanted it to work out of the box.
Not to mention you would need a way to set the SSID and any credentials.

The VM I downloaded yesterday is still syncing. I'm @ block 501514 after about 24 hours.
This is on my laptop just doing a normal sync with nothing configured. Wanted to do a clean test.

-Dave

I would use a eth cable from the rasp pi to your router.

I would look for the rasp pi   with an ip search  like advanced ip using a regular pc and windows or linux


https://www.advanced-ip-scanner.com/    like for the scanner.


I am not anti wifi but  you will be doing a long download to the rasp pi so  an eth cable is more stable for a long download.


good luck.

Nice, glad to see you've got it running. I'm having a tough time understanding this on a Rpi4
I've flashed the image to the SD card and plugged in the HD.
I'm stuck at the next set of instructions:
As far as I'm aware, myNode does not have an ip address yet as it's never been connected to the internet. Does this require a LAN cable connection? Or can I edit some file to connect to my wifi?
All I have is a blue screen with 'no signal' from the device. 
Appreciate helping me understand.

So i've finished download .ova image from https://mynodebtc.com/ and just tried it a bit.

1. By default it asks 4 processor, 4 GB RAM & 27 MB video memory
2. If you use VirtualBox, you need to install VM VirtualBox Extension Pack
3. Guest Additions isn't installed by default, so you must install it by yourself (i haven't tried it yet).
4. myNode uses Debian 10 64-bit with OpenBox desktop environment
5. The default credentials is


6. I don't need to configure anything, but if you need to configure anything (e.g. import Blockchain from your synced node or use Tor), you can't do it from their Web UI and must do it manually.
7. I saw Docker and Fail2Ban installed, even though there aren't images on Docker

For now it looks promising, i'll try it later when i'm not too lazy to configure it.

yeah you can buy this

and this

and be done with it.


backup via a cloned hdd.

real easy peasy.

If you read through the thread you can see that it can be done. And is being done.
As of this posting I have

1) raspiblitz on a RPi4 [ 03400a67375da5d5d04dd59514452ce9f0cadb2fbec65863073897d52843b61c80@24.45.24.105:9735 ]
2) full node on a RPi3
3) full node with lnd on a RPi3

The biggest issues are still crap power supplies and slow drives. (Just get a good USB SSD and be done)

Yeah, for the time and effort involved you can get a few generations out old micro PC and be done.
This is more fun / more of a challenge can I do it.

An opinion from someone who did once have a bitcoin full node on a 32 bit rPi quad core with a 64GB usb memory stick plugged in.

DON'T

That was years ago, when the blockchain was less than 50GB and where I live took about two to four days (100 hours) to sort itself out, and then two to six restarts, resynchs, unexplained halts ... whether on my best PC or the scrapheap duel core or an rPi made no difference - probability of ending up with a full node here was never better than 1/4, and expected time before it conked out was never better than a few weeks.

Presently I don't even have a full node running, and I'm usually a try-hard who'll set it up and go through half a dozen resynchs just because I want bitcoin full nodes to still belong to everyone.

On an rPi with latest raspbian, which must have python-3.7-dev and a few other things, a better bet to have your own bitcoins at home is (tentatively) electrum.
That way, you can completely trash your experimental installation and always recover your bitcoins because plenty of full nodes supply pruned blockchain info, to any new Electrum client, so that will recognise your stupid poem which you wrote down on paper somewhere safe.  That is probably more malware-proof and upgrade-proof than copying around wallet.dat files which do not always work on slightly different full node versions.

All is not lost.  There is a fairly low value toycoin called Mazacoin whose blockchain is only a few GB, so is better suited to raspberry pi full nodes than the mainchain Bitcoin.  I had much better luck running a full node for mazacoin on a raspberry pi, a few years back when those ones were traded on more of the altcoin exchanges.  You might find a few other altcoins, but beware of ones whose algorithm was designed to need particular chip architecture which the pi does not have, or whose mission goal is something abhorrent or unlawful.  See for example URO.  I found sha256d coins to be preferable for raspberry pi full nodes.  One can learn much with altcoin(s), at much lower initial investment of money and time in computer hardware.

I wonder what hardware requirements for a full node are this year ?  Four years ago, I noted that bitcoin was not too greedy with memory, definitely needed a 2 core not single cpu, and that it still took all week on the 4 core PC.
Please let us know here if you get to a full node synched up.  I've not tried this years' 64 bit rPi4, as it has continued the tradition of not working with last years' power supply.   

Looks interesting. I am downloading the VM image now. If it looks nice I'll put together another RPi setup with an SSD to see how it goes.

-Dave

let us know how this works out.

I would not mind running a full node with a wallet.

use an external ssd and space becomes a non issue.

A couple days ago I came across myNode which seems to be a working open source solution to running a full node on RPi4 along with many other apps including lighting node/wallet and BTC explorer apps. I'll be dropping the idea of compiling a node on raspian and looking forward to getting this up and running. 

For those of you who are US based and near a MicroCenter they have the RPi4 on sale at the moment:
1GB = 30.00   SKU: 950071
2GB = 35.00   SKU: 952531
4GB = 50.00   SKU: 959924


I have seen them cheaper online now and then but never at a retail location.

-Dave

the  dell,hp,lenovo  are really good at this.

I must have 8 or 9 of them scattered around nj  doing different tasks for different people.

I would not trust a laptop or a rasp pi for what these are doing.

I don't have a rasp pi 4    but thats another story.

The other issue with going with laptops instead of the micro desktops is that laptops are really not designed to run 24/7/365.
Yes you can do it, but it's not a great idea.

There are also some things you can do with a RPi that you cannot do with a small desktop in terms of placement.

Side note:
I stuck a RPi 4 with a USB SSD in my suitcase and setup a raspiblitz lighting node in my hotel room.
It was synced when I left my house so it just had about 10 hours of catching up to do [which did take a long time since the Wi-Fi in the hotel sucks] but yes I did do it.
Smaller then a laptop, lighter then a laptop and entirely a waste but I did get it up and running.

-Dave

This is probably one of those shitty 1gb. I realized my mistake after I made my post but didn't think someone would notice. Sharp eye you got there.  

I have a 2gb Ram one and it absolutely destroys any raspberry. Got it in sync with the Bitcoin network some time ago but can't get myself to install the Lightning Network. Looks like too much work and I don't know where to start.

I'll probably copy paste the data to my raspberry and experiment with the LN there. (raspiblitz)
