Electrum server discussion thread

[czaanja]

Hello, im trying to setup my own electrum server, everything seems to be ok. I downloaded the leveldb database file and synchronized to current. Server has started, but if I try to connect to it with my wallet, it got stuck on Synchronizing.
In the server log I can see:

Code:

[26/10/2013-19:53:08] SSL  217.112.174.177  1BXYiMpoWZVwfxHGrh34FYghKrDtEJdD41  30 1.7.3

But my local wallet got frozen and displays "Synchronizing..." on the status bar. There is not much load on the server, so I dont know what went wrong? When I connect to any other public server with my wallet, everything is ok.
The server is running further and processing blocks, but wallet is still saying "Synchronizing..."
Can anyone help, please?

Hey, I've just finished setting up my own Electrum server. It will remain public.

The server is electrum.icetwy.re. Onion address for Tor users: electrum2vikbmxv.onion

Ports: 8081 (HTTP), 8082 (HTTPS), 50001 (TCP), 50002 (TCP+SSL).

More info is available in the console upon connecting to the server. Enjoy

Two memory leaks were fixed sunday and yesterday.
These leaks had been there for a long time, but were revealed by the release of the 1.9 client and its multiple connections.

Please git pull!

What are the average disk, cpu load and bandwidth requirements?

Someone said about 1gb of memory is used, I guess the block chain is what it is currently. So what about bandwidth and cpu?

OT:

After getting hit with the bitcoin-qt OSX block database corruption bugs, for months, with no obvious solution or even acknowledgement on the forums, and having the same corruption issues in a ubuntu VM if it wasn't treated with kid gloves, then switching to multi-bit and getting a little concerned over the Issues list on github, and the "magic" involved that apparently means it can ignore the full block chain, then using blockchain.info but watching how the reward for hacking these online wallets rises almost exponentially. Finally I'm on electrum and feel instantly comfortable with it!

[mpjetta]

I have setup a public server to help out.

hostname: electrum.cryptopush.com
network: IPv4 and IPv6
ports: 8081,8082,50001,50002
prune: 10000
location: NY,NY USA

I have also subscribed to this thread to keep up with new server developments.

Enjoy!

[EagleTM]

There were quite a few more improvements to the server code in the past week! OPs are encouraged to git pull.

If you haven't pulled in a while: The server does no longer require bitcoind to be patched. You need run bitcoind with txindex=1 instead and may need to reindex once if you're adding the setting. Please see the HOWTO which is up2date: https://github.com/spesmilo/electrum-server/blob/master/HOWTO.md

Important: The onion address for electrum.icetwy.re has changed. This is a purely cosmetic modification, in order to have an onion address starting with "electrum".

New address: electrum2vikbmxv.onion
Previous address: 2aspcrrdseyvlaod.onion

The change has already been in effect for a few weeks now. Thanks to the user who reminded me of this!

I've signed this message and the original one with my PGP key, 0x029F116A (see my blog).

Hello i have sucessfully instaled and around two months testing our electrum server
electrum.psko.net
network:IPv4
ports: 8081,8082,50001,50002
location: Modra,Slovakia

[ThomasV]

please note that the branch "fulltree" was merged to "master".
this means that if you pull, you will need to recreate your database, or import it from the foundry.
you will also need to install plyvel.
use the 'start' and 'stop' scripts to start and stop the server.

Cool.

Is turning on irc in the config the thing to do to advertise your node?

Will there be foundry release of fulltree with a pruning limit of greater than 100?

Just in case someone is having the same trouble as me.  When I ran the foundry fulltree version from Feb I got an error saying it was deprecated.  I imagine something in the format changed.  Anyways, I am building a db with 10000 pruning limit with fulltree.  It is going and when it is done I'll tar it up and post it for others.  I only have it going at an acceptable speed by using a high memory Google Compute Engine node and having it all in RAM.  Even so, it is not fast.

If someone wants me to, I can continue to tar and make available these snapshots.

Here's the format change which makes the foundry full tree version (from Feb 17th) unusable:
https://github.com/spesmilo/electrum-server/commit/7164e2928d341fe197b68a9966542e7be1e26709
https://github.com/spesmilo/electrum-server/commit/2a8c19f5f3bdae38e9ef89bf7515dc10a7bb1893

And there's already somebody building a 10k db. I guess you'll be better of if you just wait for his db.

Just to be clear, do you mean someone other than me is already on it?

grnbrg (in IRC/#electrum) is buildung a 10k db.

I'm setting up an electrum server by following the instructions in HOWTO.md. I have some minor comments.

Unless I missed something 'start' can't find server.py.
  ln -s ~/src/electrum/server/start ~/bin/electrum-server
Should be something like:
  ln -s ~/src/electrum/server/server.py ~/bin/
  cp ~/src/electrum/server/stop ~/bin
  cp ~/src/electrum/server/start ~/bin

I needed to change the last line of the start file to log to somewhere I could write to.

The message electrum gives when starting is different from the message in the instructions. The first time I started the process I thought it didn't start right because of this.

Some guidance on what kind of disks I need for day to day operations would be good. Obviously the initial load needs a big ramdisk but once that is done are cheap SATA disks OK? or do I need expensive SAS or SSD disks? You don't recommend using tmpfs permanently do you?


Great work on electrum guys! Light clients are definitely the future.

EDIT:

Am I taking too long to process blocks here?

Is there any electrum server which updatet to bitcon core (0.9.0) and enables transactions to be propagated with 0.00001 btc fee / kb?

I think mine meets those requirements.  b.1209k.com with the normal ports.

bitcoind getinfo

    "version" : 99900,
    "protocolversion" : 70002,

I've upgraded e2.pdmc.net to 0.9.1 yesterday and adjusted the minimum fee accordingly.

Your server is not good configured when I connect to him hi don't show limit of users for all servers and when I change it with another hi disappear  from the list of servers.

Hmm, I wouldn't call that "not good configured" - the server just lost its connection to IRC. After restarting it everything is back to normal.
Anyway thank you for the hint!
