sx command line utilities - Empower The Sysadmin With Bitcoin Tools

[genjix]

Hi! The instructions are here:

http://libbitcoin.dyne.org/obelisk-setup.html

But you can also use a public Obelisk server as listed here:

http://libbitcoin.dyne.org/servers.html

(some might be down but after the crowd funding we are going to setup some nice stable servers for people)

The config file for sx is in PREFIX/share/sx/sx.cfg. Copy this to ~/.sx.cfg (PREFIX is usually /usr/local/share/)

You can install sx, obelisk and everything using:

wget http://sx.dyne.org/install-sx.sh
sudo bash install-sx.sh

Wolf0, not sure why you get that?

jago, everything works now?

This is absolutely awesome. There are so many usecases for this. The one I am currently trying to solve is how to quickly fetch the history associated with an address.

I am running my own obelisk server which looks to be working, but the history command does not return anything even after letting it run for several minutes.

bci-history works great, but relies on trusting blockchain.info from what I understand.

Is my understanding correct that sx history should return a value within a couple of seconds at most, or does it parse the entire blockchain?

-----

Edit: to answer my own question, it looks like I was trying to query a public obelisk server since that's the default. Reading the documentation and adding service = "tcp://localhost:9091" to ~/.sx.cfg fixed things.

Just got sx built under Ubuntu, thanks! Just wondering how portable 'sx' is to windows? Do I need cygwin, or is it possible to compile with VC++? Any build instructions anywhere (or pre-built binaries)?

[jago25_98]

Could really do with an RPM...

never done it, but when our infrastructure is more setup (after crowd funding) we will be deploying/testing/making builds.

The big challenge for me was to figure out how to use sx in the first place (I would just run it and it would hang)...so then I figured out obworker/obbalancer.

Since my goal was an automated setup for a Mastercoin-related project (mastercoind) that depends on 'sx', I made a script to allow for this (thats why some of the paths may reference mastercoind). You're welcome to use any of this code, if you find it helpful....it sure allows for more of an "out of the box" setup of everything:

oh this is wicked! this is exactly what I wanted! can I include them in the project?

Yes, absolutely (that was my goal). Modify as needed and go for it! Then I can pull them out of mastercoind.

I really need to get sx working on windows as well... let me spend a bit of time and look into it.

Couldn't get it to build on fedora.... could do with a rpm...

and building on windows looks like it will be a LOT of work. cygwin may be a good first step, as it has g++ 4.7 I believe...but from what I understand of it, there's still a bunch of work that has to happen to the Makefiles, etc. A native windows port (using vc++) would be even more work.

Is there a way to generate a new seed/12-word mnemonic with dice rolls?

[Hawkix]

You can always roll enough times to generate at least 256-bit entropy, form it as e.g. string (1536123 ... ) and hash it.

http://world.std.com/~reinhold/diceware.html

I'm not looking to generate a private key. I'm trying to create a libbitcoin seed and the associated deterministic wallet from the dice rolls. The sx code that generates random seeds is in https://github.com/spesmilo/libbitcoin/blob/master/src/deterministic_wallet.cpp

Code:

void deterministic_wallet::new_seed()
{
    constexpr size_t bits_needed = 8 * seed_size / 2;
    ssl_bignum rand_value;
    BN_rand(rand_value, bits_needed, 0, 0);
    bool set_success = set_seed(bignum_hex(rand_value));
    BITCOIN_ASSERT(set_success);
}

Best case would be something like...

Code:

>echo "6132235463233123456522124112542554365223124562346652123111266" | sx newseed | sx mnemonic

[genjix]

Use this Python code:

$ python
>>> "%x" % int("".join([str(int(c) - 1) for c in "6132235463233123456522124112542554365223124562346652123111266"]), 6)

Replace the string "613...." with whatever you want. I'm assuming that each digit represents a dice roll from 1 to 6.

Thanks - that worked.

I was playing around with libbitcoin/sx using a bash script wrapper to generate offline, electrum compatible wallets.

Sx is not installing via the bash script on fresh Ubuntu 12.04 64 bit installs

As posted on the sx.dyne page comments this is the result of running the script:

Code:

Error: libconfig++-dev is not installed!

Run the following command:

  $ sudo apt-get install git build-essential autoconf libtool libboost-all-dev pkg-config libcurl4-openssl-dev libleveldb-dev libzmq-dev libconfig++-dev libncurses5-dev

However all these libs are installed and the further attempts to install from the bash script just result in this message again.


What is the fix; I saw it methioned in this thread but the "algo in code" fix was ambigous at best.

Also how can we point sx at alt chains?

[genjix]

What is the output of:

$ dpkg -s libconfig++-dev

?

thanks

[RoxxR]

Any windows binaries available? Or simple build instructions?

[jcrubino]

What is the output of:

$ dpkg -s libconfig++-dev

?

thanks

Code:

main@computer:~$ dpkg -s libconfig++-dev
Package `libconfig++-dev' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

Thank you Amir.
You contributions to the bitcoin community are always among the best.
I am looking forward to using the darkwallet stack in production for not so dark things.... that said it would be nice if DarkWallet had a less ominous moniker.
