[ANNOUNCE] Electrum - Lightweight Bitcoin Client

[slush]

New Electrum server appeared at electrum.bitcoin.cz:50000 few minutes ago. Ports 80/443 are not configured yet.

[Red Emerald]

Red Emerald: yes, it's only a warning and can be ignored.

What about it continually prompting for the rpcuser and pass? I thought that should have been read from the config at /etc/electrum.conf

[slush]

Yes, it failed in reading from config for some reason. jsonrpc library then try to ask on standard input... Unfortunately have no idea what you're doing wrong...

[slush]

ThomasV, maybe you should mention somewhere that electrum.py needs disabled 'magic quotes' feature of PHP. I think it's default in PHP, at least in some distributions, so I needed to add "php_flag magic_quotes_gpc Off" to my .htaccess file.

Edit: bottom line - ports 80 and 443 are working on electrum.bitcoin.cz, too.

So the username was missing a character in /etc/electrum.conf.  Looks like vim and copy/paste didn't play nice.

It might be a good idea to log something like "username/password failed."  However, even when I put the proper values into the prompt, it doesn't work.  I just get the prompt again.  It might be better to abort when the values from the config are wrong since the prompt seems to be ignored.

hello and happy new year.

my server at ecdsa.org is currently not working; bitcoind fails to connect to the network.
I suspended the electrum server until this is resolved.
I guess we should have a way to detect non-working servers automatically.

[Red Emerald]

I think my server is working (electrum.stitthappens.com).  I don't have a client setup yet, so I can't test.  I wish the server could log a little more verbosely.

I'm leaning back towards python over node (bitcoinjs) even though my client will still be javascript. Plus, this development process is much more open, which I like.

How are you doing 80/443?  Are you forwarding them to 50000? I didn't see anything about this in ovidiusoft's guide.

There's electrum.php in repository. Just put this to /electrum.php and configure URL inside the script (to tcp connection to localhost). I also encourage you to increase the buffer from 2048 to at least 20480. ThomasV changed that on his node already, but obviously forgot to commit it yet...

I rebooted my server and moved it behind a different firewall.  When I went to restart electrum-server, I got an error from mysql.

Code:

$ electrum-server

I imagine that rebuilding the database will fix this, but thats ages.  Anyone have any suggestions?  I have the torrent of the database that slush put up (I think it was him), so that may be easiest.

I updated the guide, should be in the main tree soon.

I had that happen to me too. I had to rebuild the database.

[slush]

You can use my torrent file, it will speed up rebuilding the index a lot (it saved ~three days on my VPS .

This file is deprecated now.
The server uses json over http, and apache is not needed anymore.

[ThomasV]

I just released version 0.36

changes:
* json protocol over http (still experimental)
* during wallet creation, a dialog proposes a list of active servers

[ThomasV]

version 0.37 was released.

Changelog:
 * Bitcoin URIs can be passed to the client. To configure your browser, see http://ecdsa.org/bitcoin_URIs.html

If you let abe build the database itself it's faster. When blocks are imported, stop abe, start electrum.

To configure Chrome on Ubuntu 10.04 or maybe later versions to handle bitcoin URIs, do this first on the command-line:



$ gconftool-2 -t string -s /desktop/gnome/url-handlers/bitcoin/command "/path/to/electrum.py %s"
$ gconftool-2 -t bool -s /desktop/gnome/url-handlers/bitcoin/needs_terminal false
$ gconftool-2 -t bool -s /desktop/gnome/url-handlers/bitcoin/enabled true



This tells Gnome what to do with bitcoin URLs, and Chrome picks that up from Gnome.

nice, thanks! I'll update the page

[ThomasV]

The Electrum server at ecdsa.org has had an outage last night, because its bitcoin daemon died;
As a result, some users might have experienced problems, because the database was not updated
for several hours. I restarted it this morning, and the database is now up to date.

Sorry about the inconvenience. In the future I will implement a detection of this kind of situation;
the Electrum client should switch to a different server when its default server is not up to date.
