All right; I see. But rebalanceall is essentially the same thing, only without GUI, right?

It's closer to rebalance since you have to specify both channels. The only difference is that it's more convenient as you don't have to install the plugin (GUI supports only LND which does not require any extra software) and copy selected channels' ids manually (you select them from a drop-down menu).

Where did you find those invoices? In lightning-cli listinvoices?

I noticed them in the "Invoices" tab in RTL, but they also appear in the output of that command. Their descriptions follow this pattern: "short_channel_id1 to short_channel_id2".

It looks like I have a bunch of successful rebalancing attempts, but I am quite sure that I performed them manually.

Sorry, you are saying the plug-in works, but doing that manually is still the best options as far as results are concerned?

I believe I never had any success with the automatic method, but also no error messages either.

For Core Lightning users using RTL, manually is still the only way. So, you have to get your hands dirty in the command line for now. Which can only be good, as your learning will be better, in my opinion.

Oh really? Is it documented that lightning-cli rebalanceall simply doesn't work with Core Lightning backend? I had no idea about this.. Just started it from time to time in hope it'd do something.
It does also give you an error message if you quickly invoke it again, which makes it seem like it's doing something.

Code:

bitcoin@localhost:~> lightning-cli rebalanceall
{
   "message": "Rebalance started with min rebalancable amount: 50000000msat, feeratio: 0.5"
}
bitcoin@localhost:~> lightning-cli rebalanceall
{
   "message": "Rebalance is already running, this may take a while. To stop it use the cli method 'rebalancestop'."
}

When I said manual rebalances, I meant using the command line other than using web frontends or any other intermediary tools. So, in this sense, the rebalanceall command would also be manual! I mean, it's not that you have some front end, click a few buttons and options and click "Rebalance".

Also, the rebalance plugin needs time to find routes to be able to perform the rebaçance. And when you use the rebalance plugin, there is even one of its parameters where you specify the amount of time the plugin should be working! After that, the attempts of rebalancing stops.

I've also performed a few rebalances at the beginning when I started my node. But it's been long time that I don't try the plugin, mostly because as my node is quite small and not very active, I easily end up spending more sats in rebalancing than with forwarding payments! Never used the rebalanceall, though!

Is it possible to run more than one Core Lightning node on the same device (Pi)?

[darkv0rt3x]

Is it possible to run more than one Core Lightning node on the same device (Pi)?

You can. You just have to adjust some configs and parameters. Other than that, I think there are no limitations (but hardware) to how many nodes you can run on the same device. Check this link for some tips:

https://bitcoin.stackexchange.com/questions/89832/setting-up-and-running-multiple-c-lightning-nodes-on-same-machine
https://bitcoin.stackexchange.com/questions/83803/is-it-possible-to-run-two-lightning-network-nodes-on-top-of-single-bitcoin-core

This reply is from Rene Pickardt! Can't get much better than that!

[LoyceV]

You just have to adjust some configs and parameters.

I'd use different users for each node, so you don't have to change default locations (maybe only ports) and don't risk accidentally messing up the other installation.

If you need a GUI:

Code:

xhost +SI:localuser:user2; su - user2

As user "user2":

Code:

export DISPLAY=:0.0

I've used this to run several Core clones for Forkcoins, but stopped doing it because dbcache settings eat too much memory.

Indeed, that is probably a good avice as if accidentaly you mess up with channels databases and mix them up and end up having both deamons running at the same time using the same databases, you'll get probably wiped out from your funds of at least one of the nodes! So, be very careful!

I have a little problem with this. It worked, I did setup a second lightning node, I did make it connect with my mobile phone (using zeus), but it has now stopped working.

I run:

Code:

lightningd --conf=/home/bitcoin/.lightningmobile/lightningd.conf --lightning-dir=/home/bitcoin/.lightningmobile

And it just lags. It isn't running, because I run getinfo and this is what I get:

Code:

bitcoin@raspibolt:~ $ lightning-cli --lightning-dir=/home/bitcoin/.lightningmobile getinfo
lightning-cli: Connecting to 'lightning-rpc': Connection refused

I've killed the process, retried, nothing. I've also rebooted. My main node (from the default directory) works fine:

Code:

   "fees_collected_msat": "16898msat",
   "lightning-dir": "/home/bitcoin/.lightning/bitcoin"
}

Edit: One thing that's weird is that from above, you can see that it says "num_active_channels": 11, but from RTL, there are 10 active, and 1 inactive, which is right, because my second node is offline.

Edit #2: Whoever helps me fix it gets 9,001 Lightning sats.

Before starting your second LN node, add debug to your log-level setting in your config file.

Code:

log-level=debug

Then start the output of that debug by running this command (it will use one ssh session unless you run it with screen or some such. I use screen.

Code:

tail -f /path/to/your/LNnodeFolder/debug.log

Using screen:

Code:

screen -S cl-debug -fa -m tail -f /path/to/your/LNnodeFolder/debug.log

To bring this screen back to the terminal so that you can see what is going on, you run:

Code:

screen -r cl-debug

And to send the screen back to the "background" you hit the following shortcut keys

Code:

CTRL + A + D

You have to press CTRL and hold it, then press A and lift it and then press D and lift it and CTRL.

This way, maybe you can get some more info about the problem!
Then, start your node in a new ssh session, so that you can look to the debug session and see what is going on.

Using screen

What's the difference with screen? I don't have this command.

screen only allows you to use the same ssh session and do other stuff, while if you don't use screen, you can only run that tail command in that ssh session if you want to keep watching the messages going and to do other stuff, you have to run another terminal in your host, start another ssh connection to your device, so that you have another terminal in you device to do other stuff, while the previous session runs the tail command.

That output is not showing anything about when the daemon started.  I think you started that command after you started the daemon. Do the other way around and leave the tail[/i] command running and then, in another terminal, start the daemon and whatch the tail command window. Or, another alternative is you simply start the daemon, let it try to connect, then stop it, and edit the debug file and check when the daemon starts to see what messgaes are there!

Doesn't it seem anything wrong in here.

I can't see anything wrong either, so I assume it is working as expected, no?
Can you run any other commands via RPC?

Code:

./lightning-cli getinfo

or something like that?

Try maybe

Code:

./lightning-cli listpeers

Edited;
The cat command will not be useful there when the file gets bigger. But for now, yeah, that's ok!


Edited 2;
Check how each deamon is running with:

Code:

ps aux | grep lightningd

Show the output.

[BlackHatCoiner]

Code:

./lightning-cli getinfo

Any command without "--lightning-dir=/home/bitcoin/.lightningmobile" works properly, because it refers to my main node. By default, if you don't specify a lightning-dir, it'll be "/.lightning". The problem is with the .lightningmobile node.

That's my configuration:

Code:

bitcoin@raspibolt:~ $ sudo cat /home/bitcoin/.lightningmobile/lightningd.conf
daemon
alias=Lightning Vortex from mobile
network=bitcoin
log-level=debug
log-file=/home/bitcoin/.lightningmobile/debug.log

# incoming via tor
bind-addr=127.0.0.1:9835
announce-addr=rbfwzvypteyncgwr2iywyvt7k3vbga7hzuemtkoinivlz5tr2ofzv7yd.onion

# outgoing via tor
proxy=127.0.0.1:9050
always-use-proxy=true

I doubt it helps.

Code:

bitcoin@raspibolt:~ $ lightning-cli --lightning-dir=/home/bitcoin/.lightningmobile getinfo

If you stop `lightningd` because you thought it was stuck, your RPC calls won't work... heheh It is not stuck. The eamon simply is not sending any messages to the stdout. Let it like that and start a new terminal/session/ssh, and run the lightning-cli commands.

The daemon is running but it doesn't output anything to the stdout, so it looks like it's stuck, but it isn't.

Another alternative is that you require the prompt back and additionally, to avoid any possible message in that session/terminal, you send all possible messages from the daemon to the void, with:

Code:

lightningd --lightning-dir=/home/bitcoin/.lightningmobile > /dev/null 2>&1 &

The

Code:

/dev/null 2>&1

might even be skipped. The & "requires" the prompt back so that you can keep working/playing/enjoying!


Edited;
But something is strage, depending on the sequence you ran the commands.
ps shows you the processes running that matches the grep criteria. So, if you ran this command, after you stop the deamon because you thought it was stuck, then it shouldn't show 2 instances of the daemon running.

If you ran it before you kill the daemon, then there is some other problem with the conenction from the client to the server via RPC!

I'm not sure about this, but in one of those 2 stackexchange links I sent in a few posts above, someone says that we have to set different ports for RPC. I'm not sure if he meant for Bitcoin deamon or for the lightnind daemon.
The OP end up answering himself with this:

Listen addresses must be different, eg. 0.0.0.0:9735 and 0.0.0.0:9736, and both need to be open in router. Also rpclisten must be different, eg: 127.0.0.1:10009 and 127.0.0.1:10019

Going to check my config files of both Bitcoin Core and Core Lightning to se if I have this setting in any of them!

[vv181]

@BlackHatCoiner, does when you start the node, the debug show any output that starts with "Server started with public key xxx"?

Code:

INFO    lightningd: Server started with public key xx, alias Lightning Vortex from mobile (color #031de8) and lightningd v0.10.2

Code:

bitcoin@raspibolt:~ $ lightningd --conf=/home/bitcoin/.lightningmobile/lightningd.conf --lightning-dir=/home/bitcoin/.lightningmobile

(stuck doesn't do anything)

It being 'stuck' is actually what you want, to be honest. That's what normally happens when you run lightningd from the command line without --daemon parameter.
Have you tried, while it's stuck, e.g. in another tmux window or other SSH session, to then execute lightning-cli with the same --lightning-dir?

Yes, I do remember when I had both a Testnet and Mainnet node, that I had to use different ports indeed. May have changed by now, may not, may be a different issue entirely - not sure, but good thing to check.
Easiest way to confirm that ports are the issue would be to shut down the main Core Lightning node and then start the lightningmobile one.

We tried to address it out of Bitcointalk, via Telegram. @BlackHatCoiner thought that that "stuck" state was not good and therefore he SIGINT the deamon.

I suggested him to use either screen or tmux to run the daemon and be able to use the same terminal or at least, run the daemon with:

Code:

lightningd --conf=/home/bitcoin/.lightningmobile/lightningd.conf --lightning-dir=/home/bitcoin/.lightningmobile &

Which brings the prompt back to his control. However, he end up not having time to continue the debug, so whenever he wants/have time, we can continue it unless he figured it out already!

[BlackHatCoiner]

@BlackHatCoiner, does when you start the node, the debug show any output that starts with "Server started with public key xxx"?

No. I'm running two SSH sessions right now, one with lightningd and another with tail-ing the debug.log.

1:

Code:

bitcoin@raspibolt:~ $ lightningd --conf=/home/bitcoin/.lightningmobile/lightningd.conf --lightning-dir=/home/bitcoin/.lightningmobile

I'm not sure about this, but in one of those 2 stackexchange links I sent in a few posts above, someone says that we have to set different ports for RPC.

It did work at first. Then, it suddenly stopped working. I've had my two lightning nodes running for a few minutes. Besides, they already do listen to different ports. (9735, 9835)

Easiest way to confirm that ports are the issue would be to shut down the main Core Lightning node and then start the lightningmobile one.

Tried it. The issue wasn't resolved. The mobile node couldn't startup.
