I think that is to be expected... didn't TC warn you about open files?

It would be better if it handled the disappearance of a wallet's drive a bit more gracefully (as there is still a copy in memory that can be saved 'somewhere'). I will put it on the issues list.

Hello

I downloaded Bitcoin a few days ago and it works very well. Thanks to the developers. Bitcoin looks like that waht i searched for. A lightweight Bitcoin client. Easy to handle and fast.

I guess, my question was already answered here, but i didn't read all the 26 pages. Shame on me  Cry

Is it possible to "torify" the Bitcoin client? In the options i didn't found any proxy settings for that. But may be there is another way to realize this.

RE: setting a proxy.

With Java generally you can set up a proxy on, say, localhost port 8123, by passing in parameters on the command line.

For Mac and Linux instead of starting MultiBit with:
java -jar multibit-exe.jar

you would start it with:
java -jar -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8123 multibit-exe.jar

(I have not tried this as I don't run Tor but a user reported it worked successfully)


A bit of a complication is that the installers on Mac and Linux install the file "multibit-exe.jar" but for Windows I wrap this file into a "multibit.exe" (i.e. a Windows native exe file). Checking the manual of the product I use to make it (JSmooth) it does not look like you can pass in parameters on the command line. You can actually use the multibit-exe.jar from any of the other installers - it works on all 3 platforms.

It would certainly be easier for it to be settings in the Preferences panel that is for sure so I will put it on the TODO list.

There is a new release of MultiBit at:

http://multibit.org

Version 0.4.4

Enhancements:
+  I18n update
+  Update to bitcoinj 0.5.2


Scan of release checklist



This is mainly to update the localisation files and update the bitcoinj version (which has a fix for a sidechain block bug).

Back to the v0.5 encryption work . . .

When you add new keys/ receiving addresses to an encrypted wallet, you need to supply the wallet password.
This is to encrypt the new keys to match the existing ones.

As this would get tiresome to enter a long password repeatedly, I have put in a dialog where you can choose via a combobox to generate 1, 5, 20 or 100 new keys at a time. It is like populating a keypool. You see it when you click the 'New' on the 'Request Bitcoin' screen.

For unencrypted wallets the wallet password field is disabled but can still choose a number.

edit: finished off dialog.

Hi,

I generated an address on www.bitaddress.org and copied a private key like this one: (5KkRwQXHo7ke9yYSMH3vfFj7DqE3iwktHtkfb7NEwft2i3wJGCa)

Is it possible import this private key on Multibit? If not, is on TODO list?

Hi Teste,

Yes you can put it in a file and import it.

The easiest way to get the exact format is:
1) Create a new wallet saved to a file, say, teste.wallet
2) Export the private keys, UNENCRYPTED, to a file teste.key.
3) Open up the key file in a text editor. There is a big comment at the top that describes the format.  It is simply lines, each line containing the sipa format key - beginning with 5 - and the key creation date in a particular format. You will have an example in there to copy as a new wallet has one key in it.
4) Add in your new key and a date a bit before when you created it.
5) Import the key file back into the wallet.
6) Multibit will then replay the blocks to get the transactions and work out the balance.  

Then it is good idea to secure delete the key file so it is not lying around. If you want a quick key backup you can do another key export but add a password so that the key export file is encrypted.

edit: I have added a help 'how-to' note about this here:
http://multibit.org/help_importASingleKey.html

Hi bitcoinspot.nl,

If you do not see the currency ticker at all, it might be that you have accidentally switched it off. You should be able to do 'View | Show Currency Ticker' to get it back.

If you see the currency ticker but there is no data in it, then it is most likely that MtGox is not serving you up the data. If you look in the log/multibit_debug.log you will see an error like 'TickerTimerTask - HTTP get failed'. There is not that much we can do about that (well, other than writing an interface to another exchange). If there are any other errors in the log then post them here or PM me as it means it is something else that I need to look into.

Nopes no error.
Will you be having plans to integrate other exchanges?

Tim Molter is the developer working on XChange (which I use to get the exchange data). I think he has some early work done on Intersango but it is not yet ready to be used in production yet.

Could you PM me the log just in case there is something in there to indicate what the problem is please ?

Well there is nothing unusual in that log.
It is getting the ticker currencies ok just not the data.
I will put a bit more error logging in the code to try to pin it down in the future.

Hi HostFat,
I have put everything except bug fixes on hold whilst I am working on the encrypted wallets as there are a lot of details to work through.

I have now got the Send Confirm, Export Private Keys and Import Private Keys hooked up to the encryption. They now:

1) Check if encryption is required.
2) Prompt the user for the password.
3) Checks the wallet password correctly decrypts the wallet.
4) Actually decrypts the wallet
5) Does the Send/ Export/ Import
6) Re-encrypts the wallet afterwards.

Screenshot of the Send Confirm dialog, with some of the checking as "MS Paint" annotations:
