From my now ancient tutorial thread on setting up the server,
sudo apt-get update
sudo apt-get install git htop build-essential libssl-dev libboost-all-dev libdb5.1++-dev python-leveldb python-setuptools

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:

Did you install the python leveldb module?
You will have to install leveldb.

E_stepkrav has been upgraded too.
Did the upgrade already about 10 days ago; no problems with 0.8.2(rc1) so far...
Electrum server at electrum.bysh.me is upgraded as well and safe for use.
Done. Electrum.be has been upgraded.
Generally; no. Only if they are up-to-date with bitcoind.
Does Electrum server generally work with alt coins if you apply the bitcoind patch to d?
Couldn't these be coin generation transactions? They are the only transactions that do not have a tx_in. There should be one for each block as is listed in the error there.
I don't know. I have stopped using Abe for a long time, and no longer support it
I see that bitcoin-abe and electrum/server have been updated. Should I go ahead an upgrade or should I wait until everything is stable?
Well, I went ahead and upgraded (after making a backup of the database). The server is outputting messages like those below. Should I be worried/should I restore from backup and downgrade?
Code:
block number: 184242
WARNING: missing tx_in for tx 3977349
WARNING: missing tx_out for tx 3977349
block number: 184243

I've been thinking of an idea, but I lack the skills to follow through, so I'm going to lay it out here and let anyone who wishes take it up.
I would like to have an android client that can connect to any given electrum server, but also via TOR. I'd also like the client to have the ability to create transactions offline using confirmed transactions for which it is already aware, and connect to other clients like itself via a shared wifi hotspot like a piratebox. (http://wiki.daviddarts.com/PirateBox_DIY) In this fashion, the android client can develop a set of transactions in optimal amounts that would allow it to create several transactions without the need to reuse it's own change inputs for a time wherever the transacting parties have a piratebox (or any other accesspoint) with or without a live connection to an electrum server and whenever trust isn't an issue. The use case here is like the cash you carry in your wallet. There is only so much there, and it doesn't require live internet to work.

SSL/HTTPS ecrypts the data between your client and the server. They're only "hiding" the data from a third party inspecting the connection.
SLL/HTPPS connections increase the security?
They are needed only to hide the electrum service to the network, aren't they?
Thanks

[...] Please upgrade your servers!
Done (and worked for me). Thank you, Thomas.
many electrum servers became unusable tonight, because of very large transactions in the memory pool.
I figured out the mempool code was not efficient, and I fixed it.

I'm half the way of setting this server up. I must say that compiling bitcoind was fun. 
But bicoind needs a lot of resources, my little 512 RAM vps can't do it i guess? Opinions?
But bicoind needs a lot of resources, my little 512 RAM vps can't do it i guess? Opinions?I think it should be possible if you monitor the bitcoind process and reboot it every other day.
bitcoind is using the 43% of my 1GB of RAM x.x
I have a problem lauching the server: (the bitcoin chain is updated)

To improve installation notes at github perhaps you could add the packages needed for debian servers :
Some of them already referred but perhaps it's better to have them all in one command/place.
Code:
apt-get install python make build-essential python-leveldb libboost-all-dev libdb++-dev libminiupnpc-dev python-setuptools python-openssl
