Title: [Solved] ElectrumX Server cannot auth itself to Bitcoin daemon RPC interface
Post by: darkv0rt3x on January 29, 2021, 09:33:26 PM
Hello.

I'm trying to setup ElectrumX server so that I can connect Electrum wallet to my node. The ElectrumX server I'm using is hosted here:
https://github.com/spesmilo/electrumx

My config file is this:
Code:
# default /etc/electrumx.conf for systemd

# REQUIRED
DB_DIRECTORY = /home/[REPLACEDUSER]/Storage/electrumx

# Bitcoin Node RPC Credentials
#DAEMON_URL = http://[REPLACEDUSER]:[REPLACEDPASSWD]@localhost:8332/

# Database
DB_ENGINE = leveldb

# Username
USERNAME = [REPLACEDUSER]
# Binary
ELECTRUMX = /home/[REPLACEDUSER]/.local/bin/electrum_server

# COIN = Bitcoin
COIN = Bitcoin

# Logs
ANON_LOGS = fuck off :)

# Daemon URL
DAEMON_URL = http://[REPLACEDUSER]:[REPLACEDPASSWD]@127.0.0.1:8332/

# Misc
CACHE_MB = 1800
MAX_SESSIONS = 500
SERVICES = tcp://:10001,rpc://:8001
#EVENT_LOOP_POLICY = uvloop
PEER_DISCOVERY = self
INITIAL_CONCURRENT = 50
# See http://electrumx.readthedocs.io/en/latest/environment.html for
# information about other configuration settings you probably want to consider.


My bitcoin node config file is:
Code:
dbbatchsize=4294967000
dbcache=12288
par=1 -daemon
server=1
#rpcauth=[REPLACEDUSER]:[REPLACEDHASH]
rpcallowip=127.0.0.1
rpcport=8332
rpcuser=[REPLACEDUSER]
rpcpassword=[REPLACEDPASSWD]
maxtxfee=0.00002000
mintxfee=0.00000002

# Options only for mainnet
[main]
conf=/media/WdElements/blockchain-backup/bitcoin.conf
datadir=/media/WdElements/blockchain-backup
#debug=net
debug=rpc
debuglogfile=/media/WdElements/blockchain-backup/debug.log
addresstype=bech32
changetype=bech32
txindex=1
listen=1


But as soon as I start ElectrumX server, I start seeing this in bitcoind log:
Code:

2021-01-29T21:27:09Z ThreadRPCServer incorrect password attempt from [::1]:41976
2021-01-29T21:27:13Z ThreadRPCServer incorrect password attempt from [::1]:41976

2021-01-29T21:27:22Z ThreadRPCServer incorrect password attempt from [::1]:41976


I already tried the following and it works:
Code:
$ bitcoin-cli -rpcconnect=127.0.0.1 -rpcport=8332 -rpcuser=[REPLACEDUSER] -rpcpassword=[REPLACEDHASH] getblockchaininfo
{
  "chain": "main",
  "blocks": 668255,

      "type": "buried",
      "active": true,
      "height": 227931
    },
    "bip66": {
      "type": "buried",
      "active": true,
      "height": 363725
    },
    "bip65": {
      "type": "buried",
      "active": true,
      "height": 388381
    },
    "csv": {
      "type": "buried",
      "active": true,
      "height": 419328
    },
    "segwit": {

      "active": true,
      "height": 481824
    }
  },
  "warnings": "This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"
}

and I can see this output in bitcoin daemon when I run the above command:
Code:
2021-01-29T21:28:28Z ThreadRPCServer method=getblockchaininfo user=[REPLACEDUSER]

So, what am I missing? I can't run any ElectrumX RPC commands. For instance:
Code:
$ electrumx_rpc -p 8001 getinfo
cannot connect - is ElectrumX catching up, not running, or is 8001 the wrong RPC port?

Did you run this command under the container?

Can you share your console output here?

use this command:

Code:
$ docker ps

Then share the output here

Also, try other port instead of 8001 use 8000

Code:
$ electrumx_rpc -p 8000 getinfo

I'm not using containers. I don't even have a docker application installed.
I cloned the repository, created the service file and the config file and started the server. Then, the rpc interface isn't authorized, I can't figure out why!

A changed the rpc port in /etc/electrumx.conf to 8000 and tried what you suggested, but still the same problem.
Code:
$ electrumx_rpc -p 8000 getinfo
cannot connect - is ElectrumX catching up, not running, or is 8000 the wrong RPC port?

Can you edit the ElectrumX config again and try to change this part

Code:
SERVICES = tcp://:10001,rpc://:8001

Change it with this.

Code:
SERVICES = tcp://:10001,rpc://0.0.0.0:8000

I just got an idea from this issue below.

When I start Electrumx_server I get thin in journalctl -u electrumx:

Ok, I managed to make it work. It's catching up with bitcoin node now.

So, my setup is the following:

Unit file in /etc/systemd/system/electrumx.service

Code:
[Unit]
Description=Electrumx
After=network.target

[Service]
EnvironmentFile=/etc/electrumx.conf
ExecStart=/home/[REPLACEDUSER]/.local/bin/electrumx_server
User=[REPLACEDUSER]
LimitNOFILE=8192
TimeoutStopSec=20min

[Install]
WantedBy=multi-user.target

and then, there is the config file I saved in the default dir /etc/electrumx.conf with this content:

Code:
# default /etc/electrumx.conf for systemd

# REQUIRED
DB_DIRECTORY = /home/[REPLACEDUSER]/Storage/electrumx

# Database
DB_ENGINE = leveldb

# Username
USERNAME = [REPLACEDUSER]

# Binary
ELECTRUMX = /home/[REPLACEDUSER]/.local/bin/electrum_server

# COIN = Bitcoin
COIN = Bitcoin

# Logs
ANON_LOGS = fuck off :)
LOG_LEVEL = debug

# Daemon URL / RPC interface credentials
DAEMON_URL = [REPLACEDUSER]:[REPLACEDPASSWD]@127.0.0.1:8332

# Misc
CACHE_MB = 1800
MAX_SESSIONS = 500 
SERVICES = tcp://:10001,rpc://127.0.0.1:8000
#EVENT_LOOP_POLICY = uvloop
PEER_DISCOVERY = self
INITIAL_CONCURRENT = 50
# See http://electrumx.readthedocs.io/en/latest/environment.html for
# information about other configuration settings you probably want to consider.

At this moment, my data folder is almost 80Gb. Hope this is normal

Thanks
