And electrum-server is started correctly?

I have no experience with EC2 Sad

I'm starting it and stopping it with the 'start' and 'stop' scripts in ~/src/electrum/server, and seems to run fine and connect when I run a local electrum client. It brings up the transactions and the balances just fine.

What are these two parameters from the electrum.conf server file?

host=localhost (?? Is this correct? Since this is the Electrum server, then isn't this correct?)

password=secret ( Huh

This bugs me a lot. Do I just make something up for the password, or is this supposed to somehow be used?)

From 'electrum.conf' file:

[server]
host = localhost
#report_host =
native_port=50000
stratum_tcp_port = 50001
stratum_http_port = 8081
stratum_tcp_ssl_port = 50002
stratum_http_ssl_port = 8082
#report_stratum_tcp_port = 50001
#report_stratum_http_port = 80
#report_stratum_tcp_ssl_port = 50002
#report_stratum_http_ssl_port = 443
password = secret

Firewall? NAT?

I'm running on an Amazon EC2 server. The ports listed above, are the open ports.

My local client that I'm using to test it, is my laptop, and it connects fine to the other electrum servers. I'm using the IP port to specify the name of my server, and this works when I attach locally and use 127.0.0.1. It just doesn't work when I'm connecting from my laptop and using the IP of the Amazon server.

The 'password=secret' is the only thing that bugs me, from the server's electrum.conf file. I don't know understand it. What is it a password to?

It's frustrating because this setup went so well. I had the whole thing ready to download the block chain in about 2 hours, since I already had the bitcoind up and running; only to be stumped by a port issue.

It connects locally through tcp, http, ssl, and even https. I just tested that. I just can't connect remotely. I did uncomment stratum_tcp_ssl_port and stratum_http_ssl_port.

Trying to set up an Electrum Server and am having an issue:

* The client will not connect to it. It returns Errno: 111 Connection Refused.

The block chain is caught up. I am specifically trying to connect the client to the server using TCP, , 50001.

These are my open ports:

22    tcp   0.0.0.0/0
8081-8082   tcp   0.0.0.0/0
8333    tcp   0.0.0.0/0
50001-50002   tcp   0.0.0.0/0
0-65535   tcp   127.0.0.0/8
0-65535   udp   127.0.0.0/8
0    icmp   127.0.0.0/8

Electrum Server host file is as follows.
** Note that I do not know what the 'password' is supposed to be. I have not been able to find a reference for that.

[server]
host = localhost
#report_host =
native_port=50000
stratum_tcp_port = 50001
stratum_http_port = 8081
#stratum_tcp_ssl_port = 50002
#stratum_http_ssl_port = 8082
#report_stratum_tcp_port = 50001
#report_stratum_http_port = 80
#report_stratum_tcp_ssl_port = 50002
#report_stratum_http_ssl_port = 443
password = secret
banner = Welcome to Electrum!
irc = no
cache=yes
#irc_nick =
#ssl_certfile = /path/to/electrum-server.crt
ssl_certfile = /etc/ssl/electrum.crt
ssl_keyfile = /etc/ssl/electrum.key

# default backend is leveldb (pruning server)
backend = leveldb

[leveldb]
path = /home/ubuntu/db/electrum-leveldb-100
# for each address, history will be pruned if it is longer than this limit
pruning_limit = 100

[bitcoind]
host = localhost
port = 8332
# user and password from bitcoin.conf
user=bitcoinrpc
password=

Any thoughts?

To all server ops:

All servers are stuck on block 251526 because of a bug in the deserializer.
Pleae see https://bitcointalksearch.org/topic/electrum-181-stuck-on-block-251526-271761
Please stop your server, git pull to the latest head and restart.

From simple tests it looks as though that's all that is required to get a clean database with 251526 indexed. This isn't final yet, so there's still the chance we need to re-index from a backup... I'll let you know if that's the case but for now it doesn't appear to be necessary.

electrum.pdmc.net patched & restarted.

awesome!

Thank you! Thank you! ...

FYI: Recent electrum servers are reported to have gotten stuck when attempting to parse Block 251526.

https://bitcointalksearch.org/topic/electrum-181-stuck-on-block-251526-271761

This is preventing clients from seeing or processing any new transactions. No workaround reported yet.

As far as I'm aware it's still possible it's just no longer supported.

Is it still possible to use abe as a backend? I've read that it is deprecated, but I kinda want it this way...

Make sure you installed the electrum-server patch for bitcoind. It changes the way getblock handles multiple params.

patch -p1 <../electrum-server/patch/patch

before you make bitcoind. I checked the patch source and it has code that alters that msg. so I'm guessing it's connected.

bitcoind is using the 43% of my 1GB of RAM x.x

I have a problem lauching the server: (the bitcoin chain is updated)

I'm having the same problem. I tried monkeying with the code at line 794 (which is where the problem line lives in the current version), and i got it past this error by removing the

Code:

, 1

from the array, but that apparently opened up a host of new problems. I'm not a python coder, so I could debug it any further.. Using the latest electrum-server code (as of today), and bitcoind-0.8.2. I was running bitcoind-0.8.1 and also got this error.. Upgrading bitcoind did not help.

I was not immediately able to find a python leveldb package for CentOS 6... You will probably have to install it from source.

Have a look here: http://code.google.com/p/py-leveldb/source/browse/trunk/README

They likely have different names on Red Hat variants. You will need to do a search/lookup to match them up, or maybe someone here using yum can give you a specific list.

Hi all, i use this guide to start my electrum server: https://github.com/spesmilo/electrum-server/blob/master/HOWTO.md

But when i try to strat with comand electrum-server
consolle give me this error:

Code:

Someone can help me?

Did you install the python leveldb module?

Yes i install leveldb with root, but electrum server run with another user "bitcoin" i have to install with user bitcoin?
