Thanks! I think I'll move away from multisig for the time being.

Thanks!

There seem to be single private keys associated with single addresses in the wallet, so I suppose exporting such a private key and creating another wallet with it could work?

Hi,

I am trying to sign a message with a multisig wallet. Is it possible? I can't figure out how - whenever I paste an address into the address field, I get the error that it is not the right kind of address (for example it does not have a unique private key).

Using Electrum 2.9.3 because there is no easy way for me to run the latest 3.05 offline.

Thanks!

Thanks, splitting the words into parts might be the best idea. I know about Bitcoin Paper Wallet but I think it is complex to use for non-technical people. Also you have to trust the printer :-)

I'll check it out again, though - are they using HD wallets now, too?

Hi,

I'm writing a guide on how to give Bitcoin as a gift and I intend to recommend Electrum because of the 12 word wallet backup. I think generating a wallet for the person who will receive the gift and sending that person the 12 word sequence on paper is the best way at the moment (assuming a non-technological recipient who has no previous experience with Bitcoins). Opinions on that are welcome, too.

My real question, though: I just realized that the encryption Electrum offers is probably only for the wallet on the disk? The 12 word sequence (seed) is actually the unencrypted wallet?

Just wanted to make sure my assumption is correct?

It would be a small issue for my gifting use case because sending the seed to the recipient could be intercepted. I would prefer to send an encrypted seed and password via different channels. Encrypting the seed with external tools would make it too complicated in my opinion. I think I will still recommend using the 12 word sequence for gifting, with a word of caution :-/

Plane zu kommen, ausserdem wollte ich mal testen ob ich hier noch posten kann...

I don't plan anything illegal, in fact, I don't really want to support anything illegal. But I am tired of the countless regulations that apply in most countries, making it almost impossible to launch a web site without consulting a lawyer first. Also, there is the risk of BitCoin being made illegal.

So which country (if any) is stable enough to host an operation there, and least likely to interfere?

I like the Lazy API idea, which is to create a couple of addresses in advance to keep track of payment. It solves the problem of having to run a bitcoin server to be able to automatically track order payments.

To make it usable for end users, creating a couple of addresses should be easy, though. I guess making them install a script that generates them is not really viable. Making it a feature of the bitcoin client seems the most usable approach to me?

Not sure how many addresses would be required. Probably also depending on the business. Maybe hundreds, or even thousands?

Only got round to testing again today. Now even with -r 10 it was random if autostart would succeed or not. I added a sleep 60 command to the startup script, hopefully that should take care of race conditions.

Hm, correction - I just rebooted again and it didn't work with sudo. Could it be a random chance, depending on something else already being started or not?

Update: hm, odd, it didn't work wenn I added the -r 60 parameter to poclbm. With -r 10 it works atm.

Thanks - I now have the script working via ssh (adding the "&" after the line helped, I guess). However, starting it from rc.local it seems the graphics card once again is not visible.

Running it with "sudo myscript" in rc.local works. But is there a way to make it not run as root?

First nothing (no output, no command prompt). If I quit via ctrl+c, and then do ps -a | grep poclbm, it shows a running poclbm process. Somehow I can not kill that one, either (not even with sudo kill -9), how is that? Is that because it belongs to the script? How could I kill it?

Should I see the output from poclbm, or is it swallowed by the script?


Just curious, what does the 2>&1 part at the end of the line do?

Hi,

I tried to create a script that sets the environment variables and starts the miner. However, it only seems to hang the shell.

I tried running it via ssh with sudo. That is the first thing I need to get working before autostart, because the miner will be in a friend's cellar. If anything goes wrong, I have to be able to do stuff with ssh...

Besides, I'd like to be able to test the script before I put it on autostart.

Any ideas?

Here is the script:


What would I have to do to start both miners, btw? Is it sufficient to add a "&" to the end of the line, or does that only work in the shell?

Anyway, nothing ever showed up in the log file, and the script wasn't endable with ctrl+c.

Hm, so what is the "own X screen" thing? In fact at least the aticonfig utility worked as root. I tried running poclbm as root, but then of course it failed because root doesn't have the SDK variables set (I suppose). Maybe it would have worked as root.

The confusing thing was that if I tried to ssh before logging in on the PC, it wouldn't work (poclbm would only find the CPU), and once I logged in on the PC it would work. So I guess by logging in on the PC directly (without ssh), I got to "own the X screen"? I always used the export DISPLAY=:0 line...

Bounty for gusti - OK. I still didn't get round to trying it. My mother just came to visit, so please be patient - might even be a couple of days before I can try it.

However, I already sent 10 BTC to Raulo because I promised to send some coins in the other threat about basic setup.

I wish I already had more BTC to spend :-)

Thanks, will try that later. I guess my question was a bit premature, as I had not even really tried a startup script. I first tried to start poclbm via ssh and it failed, so I just assumed the same problem would appear with autostart.

Any ideas what might be causing the problems with ssh?

Anyway, once I got it working (the autostart), I'll send the BTC.

Is there a straightforward way to turn the log file into a rotating log?

Hi,

I offer 30BTC if somebody can help me to get poclbm to autostart. I already have bitcoind starting automatically, and poclbm works if I login on the mining computer and start it. Currently the environment variables for the Ati Stream SDK are only set for the user I login with.

However, I want it to run automatically when the PC boots up, without anybody logging in.

I have a Radeon 5970 card (2 GPUs).

Thanks!

Thanks! Any advice on how to run a script from an X11 terminal window? I seem to be stuck with trying to get poclbm to autostart, or at least starting it remotely. If I just switch on the computer (so that it boots to the login screen) and then ssh into it, there does not seem to be a running x server (my guess). In any case poclbm doesn't detect the graphics cards. As soon as I log in on the mining PC directly, it suddenly also works in the shell.

I am in over my head with this X11 stuff, no idea how it works... I've tried to execute things like startx in the ssh shell, but then it says x server is already running. On the other hand aticonfig says x server is not running. Confusing...

Any advice on autostarting the miner when the computer boots up (without me logging in)? I configured bitcoind for autostart using this script from the forum.

I suppose for the miner I somehow need to configure envrionment variables (ATI Stream SDK) to be available upon boot. Plus it is confusing as I will start two instances of poclbm, one for each GPU I have.

I suppose I could still copy the script above in principle. One more problem, though: I think I want to pipe the verbose output of poclbm into a script that will parse and log the information, so I suppose I would start it like this


But what PID will be returned if I feed this to the start-stop-daemon command? If I use pipes, is the script I pipe into dependent on the originating script, that is, if I kill poclbm, will myparser.py also be killed?

Anything else I need to consider?

Thx!

Update: I just tried to start poclbm via ssh login from another computer. If the miner only shows the login screen, I get

Once I log in to my account on the miner, I can also start poclbm via ssh.

What could be the reason? I don't suppose it is the environment variables, as they are configured in .bashrc. So I assume they should be known if I log in via ssh, too.

Thanks for this script, very useful.

I only changed two things (without knowing much about shell programming):


Where /usr/local/bin/ has to ba adapted to the proper path. I used some bitcoin ubuntu package, so for me it was actually /usr/bin/

It seems to make more sense to me like that, as $NAME is referenced everywhere in the script. Not sure if it runs properly in the original version? IN any case, it seems to work for me now.

Yeah, I'll probably fork poclbm on GitHub.
