How to compile xmr-stak (2.5) under CentOS 6 for CPU mining cryptocurrencies in November 2018

In continuing our crypto series with xmr-stak we update the old article How to compile xmr-stak (2.4.5) under CentOS 7 for CPU mining cryptocurrencies with the new version 2.5 and tested the build procedure with the old CentOS 6.

In crypto mining it is important to have latest version of the mining software, because crypto world is super dynamic with thousands crypto currency and tens of algos, which ever month might be changed and updated!

Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability. Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:

STEP 1) Update your system and install the following dependencies

Because xmr-stak need a newer version of GNU GCC than the CentOS ships with you must install GNU GCC 5.1 at least. Because the latest versions have better optimizations for the processors we use here GNU GCC 7 from Software Collection repository – more information for this repository here: How to install new gcc and development tools under CentOS 7

Install xmr-stak 2.4 in a machine with NVIDIA video card under Ubuntu 18.04 LTS

This is simple “how to” to get started mining crypto currency with XMR-STAK using cryptonight algorithm like monero, electroneum, intensecoin and more. This time we are going to use PPA repository for the NVIDIA drivers and the CUDA toolkit. Installing the official NVIDIA driver we can use our ASUS ROG POSEIDON GTX 1080Ti Platinum Edition to mine along with our processor AMD Ryzen Threadripper 1950X (16 cores with 32 threads with 3.4GHz base frequency and boost to 4GHz).
XMR-STAK could be used only for CPU mining, but now we installed an NVIDIA card and Ubuntu 18.04 LTS. Ubuntu is installed with the default open source NVIDIA driver (nouveau), which is OK for every day and office use, but if you like to game or to mine you must install the proprietary driver shipped by NVIDIA. The following howto will show you how to do it!

Just follow the simple steps and you’ll have an optimized GPU and CPU miner for cryptonight crypto currencies:

STEP 1) Install Ubuntu 18.04 LTS.

If you do not have Ubuntu installed yet it is time to do it. You can see how easy is to do it here even if you have multiple systems installed – Install Ubuntu Desktop 18.04 LTS on a PC with existing windows 10 and linux If your machine is only for mining and you want to have only one system it’s even simpler and you can still follow the above howto!

STEP 2) Install NVIDIA proprietary driver and CUDA Toolkit

Here we show you a brief command set to execute, but if you want a detailed explanations you could check the two howtos on the subject: Install NVIDIA proprietary drivers on Ubuntu 18.0 LTS (x86_64) and Install NVIDIA Cuda on Ubuntu 18.04 LTS (x86_64)

myuser@srv:~$ sudo apt -y update
myuser@srv:~$ sudo add-apt-repository -y ppa:graphics-drivers/ppa
myuser@srv:~$ sudo apt -y update
myuser@srv:~$ sudo ubuntu-drivers autoinstall
myuser@srv:~$ sudo reboot
myuser@srv:~$ sudo apt install -y nvidia-cuda-toolkit gcc-6

Check if your driver is loaded successfully before continuing:

STEP 4) Compile XMR-STAK

First get the sources from the official github repository. The master is now with tag 2.4.7. If you do not know how to work with git and want the exact tag version it is easy, just open in the browser “https://github.com/fireice-uk/xmr-stak” change “Branch:master” (click on it and a dropdown will appear, click the tab “Tag” and select your tag version) to “Tag:2.4.7” then click on “Clone or download” on the right and click on “Download ZIP” and it will offer you to download a zip file with the name 2.4.7.zip (here is the URL: https://codeload.github.com/fireice-uk/xmr-stak/zip/2.4.7).
This step it is important to note that we MUST build XMR-STAK with GNU GCC 6 (6.4.0) and the default GNU GCC in Ubuntu 18.04 LTS is 7 (7.3.0), so we export environment variables “CC” and “CXX” to use gcc-6. Exporting CC and CXX is enough to compile succeessfully no need to mess with “update-alternatives”.

myuser@srv:~/xmr-stak/build$

STEP 5) Execute XMR-STAK, but before you must execute some tuning exports for the GPU and the linux kernel

Now is the time to use XMR-STAK.

myuser@srv:~/xmr-stak/build$ sudo sysctl -w vm.nr_hugepages=128
myuser@srv:~/xmr-stak/build$ export GPU_FORCE_64BIT_PTR=0
myuser@srv:~/xmr-stak/build$ export GPU_MAX_HEAP_SIZE=100
myuser@srv:~/xmr-stak/build$ export GPU_USE_SYNC_OBJECTS=1
myuser@srv:~/xmr-stak/build$ export GPU_MAX_ALLOC_PERCENT=100
myuser@srv:~/xmr-stak/build$ export GPU_SINGLE_ALLOC_PERCENT=100
myuser@srv:~/xmr-stak/build$ cd ./bin
myuser@srv:~/xmr-stak/build/bin$ ls -la
total 35804
drwxrwxr-x 2 myuser myuser     4096 Jul 19 16:13 .
drwxrwxr-x 4 myuser myuser     4096 Jul 19 16:05 ..
-rw-rw-r-- 1 myuser myuser  1614230 Jul 19 16:05 libxmr-stak-backend.a

-rwxrwxr-x 1 myuser myuser  1075784 Jul 19 16:06 xmr-stak
myuser@srv:~/xmr-stak/build/bin$ ./xmr-stak 

Always execute the exports before running the xmr-stak binary.
As you can see the XMR-STAK is in

./bin/xmr-stak

under the “~/xmr-stak/build”.

STEP 6) Mining with XMR-STAK.

Execute the program and follow the first run questions. Here you can see a MONERO configuration and the first run – Mining Monero with xmr-stak 2.4 in a machine with NVIDIA video card under Ubuntu 18.04 LTS.

* Options of the XMR-STAK program

As you can see all the algo you can use with this program – new and classic (the old) criptonight coins to mine like Monero, Electroneum, IntenseCoin and many more!

* Troubleshooting – the right version of GNU GCC

You must use GNU GCC 6, because version above 6 (7 and 8) are not supported by the NVIDIA 9.1 Toolkit. So if you end up with this error you must change to the version to 6 from 7 (the default in Ubuntu 18.04 LTS is GNU 7.3.0). GNU GCC 6 was installed as a dependency to NVIDIA 9.1 Toolkit in STEP 2) and we exported two environments “CC” and “CCX” in STEP 4)

The solution is simple as said, just export CC and CXX before compilation in the same terminal console:

myuser@srv:~$ export CC=/usr/bin/gcc-6
myuser@srv:~$ export CXX=/usr/bin/g++-6

Mining Monero with xmr-stak 2.4 in a machine with NVIDIA video card under Ubuntu 18.04 LTS

Here are all the steps you need to begin mining Monero crypto coin with XMR-STAK 2.4. We can use our ASUS ROG POSEIDON GTX 1080Ti Platinum Edition to mine along with our processor AMD Ryzen Threadripper 1950X (16 cores with 32 threads with 3.4GHz base frequency and boost to 4GHz). As you’ll see our processor has better performance with cryptonight v7 than our GPU.

STEP 1) Install all the needed software

  1. Install linux distro – Ubuntu 18.04 LTS
  2. Install NVIDIA proprietary driver
  3. Install NVIDIA CURA Toolkit
  4. Build XMR-STAK

This step is a matter of another howto, you can check all the step and detail explanations here – Install xmr-stak 2.4 in a machine with NVIDIA video card under Ubuntu 18.04 LTS. Skip it if you just followed the above howto and you want to see an example of how to mine the Monero coins with XMR-STAK using CPU and GPU power.

STEP 2) First run of XMR-STAK

If you followed our howto above you should have installed XMR-STAK in “~/xmr-stak/build/bin”, so all the examples will be run from this directory.

myuser@srv:~/xmr-stak/build/bin$ ./xmr-stak

You could use monero7 or cryptonight_v7to mine Monero. The pool we use is under “Pool address:” – pool.monero.spacepools.org:3333 You cannot mine crypto without to be part of a pool of other mining “people”, because the difficulty is too big for solo mining! So choose your mining pool carefully – by the “Total Pool Fee”, which for the Spacepools is 0.1% and the stability of the pool.
The username is your MONERO wallet address (we changed our to invalid 111111111111111111111111111111111111111111111111111111111111111111111, DO NOT USE THIS ADDRESS) – check this to see how you can generate monero wallet address – Generate a new Monero address (wallet). The password in most cases is your email address, with which you could change some account information in the pool web page.

It is good to see

Result accepted by the pool.

it means your discovered a hash and you are going to be awarded by the pool for your mining share! As many as “accepted results” as good as for you!

As you can see our ASUS ROG POSEIDON GTX 1080Ti Platinum Edition without any overclocking has 771.5 H/s of Cryptonight v7 algorithm!
Our AMD Ryzen Threadripper 1950X (16 cores with 32 threads with 3.4GHz base frequency and boost to 4GHz) without any overclocking has 1295.1 of Cryptonight v7 algorithm! The performance of the CPU is almost double the performance of the GPU.
Our motherboard is ASUS ROG ZENITH EXTREME with 4x8Gbytes (G.Skill Trident Z RGB DIMM Kit 32GB F4-3200C14Q-32GTZR) of RAM running in fourth channel mode.

There are three control keys to display additional information of your XMR-STAK. Press one of the key during the program execution. In the above first run we used “h” and “r”.

'h' - hashrate
'r' - results
'c' - connection

The difficult is constant 50000 and you see we have multiple results, so we can try to higher it with another port (check for this the configuration page of the pool – https://dwarfpool.com/xmr/). The stats is “Earning in last 24 hours: 0.00753535 XMR”, “Current balance: 0.00732356 XMR” and ” Unconfirmed: 0.00078419 XMR” (in most cases all of it will be confirmed successfully), so the total monero we mined is “0.00810775 XMR” for these 14 hours with our machine and the estimate for the next 24 hours is “0.01440000 XMR” (for the current price you’ll earn 1.832300 USD for 24hours with this machine).

The configuration files are

  • config.txt – the general config
  • pools.txt – configuration for what coin your are mining and which pool you are using. You can tune the rig naming and additional pools.
  • nvidia.txt – configuration for GPU miner part – GPU threads, blocks and affine_to_cpu. Definitely check this out.
  • cpu.txt – configuration for the cpu miner part – Thread configuration for each thread – a line for each core. CPU affinity, power mode and more.

These files are generated on the first run with default values and then you could quit the xmr-stak and edit the files with text editor.

* Options of the XMR-STAK program

As you can see all the algo you can use with this program – new and classic (the old) criptonight coins to mine like Monero, Electroneum, IntenseCoin and many more!

How to compile xmr-stak (2.4.5) under Fedora 28 for CPU mining cryptocurrencies

Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability under Fedora 28, not all setups have a good video GPU, but you can have a decent CPU, which could be used to mine! For example AMD Ryzen Threadripper 1950X has a good performance on my crypto algorithms, even a better performance than the GPU mining.
Here we use AMD Ryzen Threadripper 1950X, which has 12 cores and 32 threads. Our setup is ASUS ROG ZENITH EXTREME (X399 Chipset) motherboard with 32G (4x8G CROSSHAIR VI HERO) DIMM DDR4 Synchronous Unbuffered (Unregistered) 2133 MHz (0.5 ns) and AMD Ryzen Threadripper 1950X. It can do 1253.5 cryptonight_v7 hashes per second.
Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:

Update your system and install the needed dependencies

How to compile xmr-stak (2.4.5) under CentOS 7 for CPU mining cryptocurrencies

Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability. Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:

STEP 1) Update your system and install the following dependencies

Because xmr-stak need a newer version of GNU GCC than the CentOS ships with you must install GNU GCC 5.1 at least. Because the latest versions have better optimizations for the processors we use here GNU GCC 7 from Software Collection repository – more information for this repository here: How to install new gcc and development tools under CentOS 7

[myuser@srv ~]# sudo yum update -y
[myuser@srv ~]# sudo yum install -y centos-release-scl epel-release
[myuser@srv ~]# sudo yum install -y cmake3 devtoolset-7-gcc* hwloc-devel libmicrohttpd-devel openssl openssl-devel make git screen

STEP 2) Compile the mining program xmr-stak

[myuser@srv ~]# scl enable devtoolset-7 bash
[myuser@srv ~]# git clone https://github.com/fireice-uk/xmr-stak.git

Generate a new Monero address (wallet)

The generation of a new Monero address is super simple, just use

monero-wallet-cli

and personally create your new address.
And for those of you, which do not have “monero-wallet-cli” command or even do not know what is this, check out our howtos here:

  1. Install Ubuntu 16 LTS (comming soon)
  2. Building from source a Monero node under Ubuntu 16 LTS

Go to your directory where is the monero-wallet-cli binary and execute the following command:

srv@local: cd ~/monero/build/release/bin
srv@local:~/monero/build/release/bin$ ./monero-wallet-cli
This is the command line monero wallet. It needs to connect to a monero
daemon to work correctly.

Monero 'Helium Hydra' (v0.11.1.0-master-a03d34f)
Logging to ./monero-wallet-cli.log
Specify wallet file name (e.g., MyWallet). If the wallet doesn't exist, it will be created.
Wallet file name (or Ctrl-C to quit): mycryptomonero
No wallet found with that name. Confirm creation of new wallet named: mycryptomonero
(Y/Yes/N/No): Y

Use the "help" command to see the list of available commands.
Use "help <command>" to see a command's documentation.
Always use the "exit" command when closing monero-wallet-cli to save 
your current session's state. Otherwise, you might need to synchronize

is your public Monery address, which could be used to receive Monero coins. Monero has also a view key:

61c3f248516175896bda32c85fa36452081ba79aecde962ea199d5e0ffb3080d

which can be used ONLY to view balances (In fact this key could be used to generate a new Monero wallet address, which has read only capabilities of your original wallet address – this is useful when you save your original keys offline and you just want to check balances on an online box).
On Line 9 (highlighted) you enter the name of your wallet, if new it will be created.
On Line 11 (highlighted) expected to confirm creation of new wallet with the name you entered in Line 9.
On Line 28 (highlighted) List of available languages for your wallet’s seed – the words, which could be used to recover access to your wallet.

After generating the address two things must be done:

  1. Backup your Monero wallet file, which is placed in the same directory where the monero-wallet-cli is:

    So you must backup the two files starting with your Monero wallet name (you entered above): “mycryptomonero” and “mycryptomonero.keys”

  2. Backup your password for the private key!

* Open existing wallet.

And available commands.
You can open your existing wallet when asked for the wallet file name enter the name “mycryptomonero” (the file name is expected to be in the same directory as the monero-wallet-cli) and then enter the password. And if you enter “help” you can see all the available commands of the wallet program “monero-wallet-cli”

srv@local:~/monero/build/release/bin$ ./monero-wallet-cli
This is the command line monero wallet. It needs to connect to a monero
daemon to work correctly.

Monero 'Helium Hydra' (v0.11.1.0-master-a03d34f)

* For a maximum security you could do the following

In fact you could do the following:

  1. Install a fresh copy of Ubuntu
  2. Build from source the Monero software
  3. Unplug the system from the Internet
  4. Generate the wallet
  5. Backup the wallet
  6. Generate a wallet from your view key to check balances only

Thus your wallet will never be exposed on an online machine!

* It is absolutely necessary your crypto wallet addresses to have a password for security reasons and DO NOT FORGET IT you cannot recover the password therefore your access to the wallet! If you lose your password you lose ALL your funds in the address! It’s better to write it down somewhere on a safe physical place.

Running a Electroneum node from source under Ubuntu 16 LTS

This howto is made to show you how to run a Electroneum node. To run a Electroneum node we need the official electroneum daemon software:

electroneumd

which will start and wait for the network synchronization – our Electroneum node will receive all the blockchains of the network!
Installing (or compiling it) the Electroneum software of the official site will ensure you have the right software for generating and sending/receiving transactions securely and privately! Always use your node software for generating the Electroneum wallet address, DO NOT TRUST any sites, which offer you a creation of Electroneum wallet or any other crypto currency. In crypto world the one how controls the private key of the wallet (which is generated with the creation of the wallet) controls the Electroneum wallet address so controls your funds! Just Install or compile a Electroneum node software – Building from source a Electroneum node under Ubuntu 16 LTS and you’ll everything you need to manage your Electroneum funds!
It’s worth mentioning again this section of Electroneum node howto (if you read other howtos for running a node you would probably read it, but it so important we include it in every howto!!!):
And also be warned DO NOT use insecure sources when:

  1. installing Ubuntu, install it from a cd/dvd/usb downloaded from the official Ubuntu site here.
  2. installing all the needed dependencies from official sources only, not recommended the PPA reposigories, neither!
  3. install yourself the “electroneumd” program (the official Electroneum software), which will create a Electroneum node and after network synchronization could be used to create a Electroneum node.

Three simple rules could almost eliminate leaking your private key to hackers, which in blockchain world means losing your money…
And before start the installation a performance advice:

USE SSD

Technically with Electroneum node you can still use hard drive, but it is slow, but not impossible as some of the older crypto currencies like Ethereum, Bitcoin, Monero and so on.

STEP 1) Install Ubuntu 16 – our howto will be available soon here.

STEP 2) Building from source a Electroneum node

Check out our howto “Building from source a Electroneum node under Ubuntu 16 LTS“.

STEP 3) Start the Electroneum node

if you have followed the howto in STEP 2) you probably have “electroneumd” installed in “~/electroneum/build/release/bin”, so run it with:

ubuntu@srv.local:~/electroneum/build/release/bin$ ./electroneumd &> ./electroneumd.log

It is a good practice to run it with screen and in an infinite loop – if the program crashes it will start automatically and you’ll always have a synchronized node, of course, if you do not need a Electroneum node running all the time the infinite loop is not needed. The user could just start the node, wait for synchronization and then make your transactions and stop the node, after several days you can start it up the catching up the synchronization won’t take much time:

ubuntu@srv.local:~$ screen -R electroneum
ubuntu@srv.local:~$ cd electroneum/build/release/bin
ubuntu@srv.local:~/electroneum/build/release/bin$ while true; do ./electroneumd &> ./electroneumd.log;done

STEP 3) Wait for the blockchain network synchronization

This step could take significant amount of time, server resources and network bandwidth! USE SSD(s) for your home directory, because the blockchain database will be saved at your

home directory/.electroneum/

If you want to move it on another server or directory (or device) you must copy this directory to the new location.
The generated IO is so extensive that for a traditional hard drive probably will be difficult to catch up with the synchronization.
When you run “electroneumd” it will check the current state of the network and the current state of your Electroneum node, so no matter it is started for the first time or not a network synchronization is needed, your node need to be synchronized with the Electroneum network to be used for all kind of actions in the network (create a wallet, transfer funds and more).
Here is the output of just started Electroneum node:

There is also a log of all the output of the “electroneumd” under the “~/.electroneum/electroneum.log”.

“~/.electroneum/” is where all the data will be saved for the Electroneum node

You can see when your Electroneum node is fully synchronized and you may use the “electroneum-wallet-cli”.

As you can see we redirected the output of the program in a file in the same directory as “electroneumd”. The default output is informative here is what we can see about the blockchain syncronization:

  • how many blockchains we are behind the Electroneum network – “Sync data returned a new top block candidate: 1401 -> 255582”
  • how many days we are behind the Electroneum network – “Your node is 254181 blocks (176 days) behind”

At present with SSD and 16G RAM on a intel i7 processor and a fast Internet connection 100Mbps the full synchronization took about 12 hours and 18G of storage space.
After a successful full synchronization, in the log you’ll have:

You are now synchronized with the network.

and you are ready to use “electroneum-wallet-cli” or the others program to manage your funds – for example send, receive, check balance of your funds.
If you stop and start the program it will start the synchronization from the point you stopped.

Building from source a Electroneum node under Ubuntu 16 LTS

The program, which makes an Electroneum node from your computer, is called

electroneumd

You need a electroneum node to send, receive coins securely and privately and to maintain your wallet personally. DO IT YOURSELF – the most secure way of generating a electroneum wallet address and making transactions such as send and receive coins. As you usual here you’ll see: do not trust any site for generating an electroneum wallet address, use the official tools from this package to generate your addresses and to send and receive coins!
Sometimes you’ll see an easy way of installing the node such as a snap package or docker imagedo not trust them! Most of the time they are unofficial releases or 3rd party releases – trust only to the official site and repository all other packages our there bring more risk than features.

STEP 1) Update your system and install dependencies

sudo apt-get update -y
sudo apt-get -y upgrade
sudo apt-get install -y build-essential cmake pkg-config libboost-all-dev libssl-dev libunbound-dev libminiupnpc-dev libunwind8-dev liblzma-dev libldns-dev libexpat1-dev libgtest-dev doxygen graphviz

STEP 2) Get the “electroneumd” code and compile it

You could change to stable release (probably the last tag) if you like.

git clone https://github.com/electroneum/electroneum
cd electroneum
export CFLAGS="-march=native -O2 -msse3 -fomit-frame-pointer -pipe"
export CXXFLAGS="${CFLAGS}"
export CHOST="x86_64-pc-linux-gnu"
make

STEP 3) Check is everything is OK, installed electroneumd – Electroneum ‘Helium Hydra’

ls command shows the additional programs in the package.

srv@local:~/electroneum$ cd ./build/release/bin
srv@local:~/electroneum/build/release/bin$ ./electroneumd --version
Electroneum 'Helium Hydra' (v0.11.1.0-6a0535e)
srv@local:~/electroneum/build/release/bin$ ls 
electroneum-blockchain-export  electroneum-blockchain-import  electroneum-wallet-cli  electroneum-wallet-rpc  electroneumd

Most used programs are electroneumd and electroneum-wallet-cli, which offers a command line management of a electroneum wallet addresses.

Send coins in Groestlcoin network with Groestlcoin Core (cli)

Here are the steps needed to make a secure transfer of your funds under linux distro of Ubuntu. To be able to transfer money securely without any 3rd party involved (no online wallet) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address we need a running Groestlcoin node using Groestlcoin Core tool:

groestlcoin-cli

The cli tool for managing the Groestlcoin wallets.

STEP 1) Install and run an Groestlcoin node with groestlcoind

Here you can follow this tutorial – Running a Groestlcoin node (wallet cli) from source under Ubuntu 16 LTS.
The Groestlcoin node must be running and synced with the Groestlcoin network.

STEP 2) Check how many funds you have in your Groestlcoin wallet address

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaccounts
{
  "": 0.00000000,
  "myfunds": 527.36851543,
  "test": 0.00000000
}

So we have

myfunds account

with 527.36851543 Groestlcoin coins, an account could have multiple Groestlcoin addresses and a wallet could have multiple accounts (as you can see from the example above) , so we can check the amount of coins on each address associated with the account:

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
[
  [
    [
      "FabGnY2ovd3jnddgyjiltd456hdfjklFBs", 
      527.36851543, 
      "myfunds"
    ]
  ]
]

You can see there are 527.36851543 Groestlcoin coins in our account “myfunds” in the Groestlcoin wallet and the Groestlcoin address is FabGnY2ovd3jnddgyjiltd456hdfjklFBs

STEP 3) Unlock your wallet

The wallet is encrypted with a password, so before doing any transactions you must unlock the account for a given amount of time with:

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli walletpassphrase "my_wallet_pass" 300

So your wallet will stay unlocked for 300 seconds, this is the purpose of the third parameter.

STEP 4) Send the amount you like to the Groestlcoin wallet address you like

BE CAREFUL the operation is irreversible, if you put wrong address or unknown or unexciting one, you’ll lose your Groestlcoin coins!!
We want to send 2 coins to “FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe”

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli sendfrom "myfunds" "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe" 2
3293d8f8acc2689ff54fe70a28da24cd313c324f1f335e80d22add08588d73d1

If you see the transaction ID, it means the you have executed the command successfully and you can check the status of the transaction.

STEP 5) Check the transaction status.

The status of your transaction could be checked in sites offering Groestlcoin block explorer sites like

https://groestlsight.groestlcoin.org/

Here is the screenshot of the status page:

main menu
Transaction details in https://groestlsight.groestlcoin.org/

You can see there are two addresses and a fee, which is just a “0.0000226GRS”, the transaction 2 GRS has (S), which means “Spent” and the 0.04326832 GRS (U), which means unspent, but it was needed to complete the transaction. So you spent 2.0000226 GRS to transfer 2.00 GRS.
And verify the other address has the coins:

srv@local:~/groestlcoin-core/bin$ 
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
[
  [
    [
      "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe", 
      2.00000000, 
      "mytestwallet"
    ]
  ]
]

Here is the whole output of the “/groestlcoin-cli” tool:

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaccounts
{
  "": 0.00000000,
  "myfunds": 527.36851543,
  "test": 0.00000000
}
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli walletpassphrase "my_wallet_pass" 300
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli sendfrom "myfunds" "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe" 2
3293d8f8acc2689ff54fe70a28da24cd313c324f1f335e80d22add08588d73d1
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
[
  [
    [
      "FabGnY2ovd3jnddgyjiltd456hdfjklFBs", 
      525.32522451, 
      "myfunds"
    ], 
    [
      "Fjqkflgitg459tdfgjjkrthurDFGFhghhj", 
      0.04326832
    ]
  ]
]
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaccounts
{
  "": 0.00000000,
  "myfunds": 525.36849283,
  "test": 0.00000000
}

Also you might want to delete your shell history because of the saved password phrase!

Troubleshooting

If you get

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli sendfrom "myfunds" "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe" 2
error code: -13
error message:
Error: Please enter the wallet passphrase with walletpassphrase first.

You must unlock your account! If you did it but still the error persisted you probably have to increase the unlock time. Look STEP 2)

* All Groestlcoin addresses in this howto are changed for security reasons.

Backup and restore your Groestlcoin address wallet (cli)

In real world backups are lifesavers and in crypto world the backups are even more important! Backup everything about your crypto wallet and node install!
If you have followed our howtos (Running a Groestlcoin node (wallet cli) from source under Ubuntu 16 LTS and “Building from source a Groestlcoin node (cli only) under Ubuntu 16 LTS“) you would have the correct software for managing the Groestlcoin wallet and all the paths bellow will be accurate.

STEP 1) Backup of Groestlcoin wallet

If you want to backup up your Groestlcoin (addresses) wallet you need to find your

wallet.dat

file the place for it is in your

“home directory/.groestlcoin/wallet.dat”

So first stop the Groestlcoin Core program with one of the following command:

  • By sending kill signal:
    srv@local:~$ killall groestlcoind
    
  • OR in your screen or shell of the running program ctrl+c will stop it

After you wait for the Groestlcoin Core to exit you can check the logs in

~/.groestlcoin/debug.log

2018-04-12 01:00:52 addcon thread exit
2018-04-12 01:00:52 torcontrol thread exit
2018-04-12 01:00:52 opencon thread exit

2018-04-12 01:00:52 Shutdown: done

So now you can copy to a secure place your

“home directory/.groestlcoin/wallet.dat

In our real world example the path is “/home/ubuntu/.groestlcoin/wallet.dat”

srv@local:~$ cp /home/ubuntu/.groestlcoin/wallet.dat /home/ubuntu/backups/cryptos/groestlcoin-wallet.dat

STEP 2) Restore Groestlcoin wallet

To restore our wallet from a backup you also need the Groestlcoin wallet program (Groestlcoin Core – the Groestlcoin node) not to be running, so if it is started just follow the STEP 1) to stop it. Then override

“home directory/.groestlcoin/wallet.dat

with your backup file (the name of the file must be “wallet.dat”!!! It is important because your backup file could have any name). So in our real world example we override our /home/ubuntu/.groestlcoin/wallet.dat with our backup:

srv@local:~$ cp /home/ubuntu/backups/cryptos/groestlcoin-wallet.dat /home/ubuntu/.groestlcoin/wallet.dat

And then start your Groestlcoin wallet program with option

-rescan

this option is required when you first start the Groestlcoin Core with your backup wallet to “Rescan the block chain for missing wallet transactions on startup”, if you do not start the program with “-rescan” you could have strange numbers for your funds when checking with “groestlcoin-cli”

srv@local:~$ cd ~/groestlcoin-core/bin
srv@local:~/groestlcoin-core/bin$ ./groestlcoind -rescan &> groestlcoind.log

You could check debug.log and you’ll see the transactions for your wallet
