Ubuntu 16/18 LTS – load a new kernel without rebooting the server

Here are the commands needed to load a new kernel without rebooting your server or desktop computer. Why you need this? As said in our first article for CentOS 7 – sometime rebooting a server could take 5 to 10 minutes and loading a new kernel is just up to a minute. In fact in most cases loading the new kernel and starting the system then is just under 20-30 seconds, so upgrading your server even with new kernel is super easy lately. We tested it on Ubuntu 16 and Ubuntu 18 servers and it was successful. The system uses systemd and the process is really easy and safe for the systems.

When the processes is initiated the system shutdowns normally (shutting down all running service with systemd) and then load the system immediately with the new kernel and starts the services as usual!

So no need to worry about unflushed data or not proper shutdown of a service! It’s like a normal reboot but without a hardware reboot and is a lot faster!
Here is what is required to load a kernel without hardware rebooting your computer box:

  1. kexec-tools
  2. Load the new kernel, initram file and the command line arguments with “kexec”
  3. Start a systemd target – kexec.target

Ubuntu 16/18 LTS using kexec to load a new kernel

The real commands only for Ubuntu 16/18 LTS:

sudo apt -y install kexec-tools
sudo kexec -l /boot/vmlinuz-4.15.0-33-generic --initrd=/boot/initrd.img-4.15.0-33-generic --command-line="root=UUID=061b2936-34bf-4da3-b7d2-b8bde0899f03 ro  quiet splash"
sudo systemctl start kexec.target

Here is a real world example with all the output:
And again update your system to see if there is a new kernel and install “kexec-tools”. In our case indeed there is a new kernel – vmlinuz-4.15.0-33-generic

On the above configuration question mark “” and press Enter.

So we performed an update and there was a new kernel vmlinuz-4.15.0-33-generic, which we would like to load without hardware reboot.
Here is our new kernel in “/boot”

myuser@srv:~$ ls -altr /boot/

Now we know the kernel and initram file names we just check the kernel arguments in the kernel, load them with kexec and start an systemd target to load the new kernel:

myuser@srv:~$ grep vmlinuz-4.15.0-33-generic /boot/grub/grub.cfg 
        linux   /boot/vmlinuz-4.15.0-33-generic root=UUID=061b2936-34bf-4da3-b7d2-b8bde0899f03 ro  quiet splash $vt_handoff

                linux   /boot/vmlinuz-4.15.0-33-generic root=UUID=061b2936-34bf-4da3-b7d2-b8bde0899f03 ro  quiet splash $vt_handoff init=/sbin/upstart
                linux   /boot/vmlinuz-4.15.0-33-generic root=UUID=061b2936-34bf-4da3-b7d2-b8bde0899f03 ro recovery nomodeset

myuser@srv:~$ sudo systemctl start kexec.target
Connection to srv closed by remote host.
Connection to srv closed.

Use the first line of the grep output above (or you can cat the file and see what is in it if you have any doubts) to take the proper kernel boot arguments and do not include anything starting with “$”.

As you can see systemd performs a normal shutdown of all services and targets.

main menu
Normal shutdown

The ssh connection is immediately closed because the reboot is initiated.
After 10-15 seconds our host is alive and the new kernel is loaded successfully:

root@test ~ $ ssh root@srv
root@srv's password:

Because we do not wanted to mess up the two output in one article we decided to split it in two separate ones, so here is the previous one for CentOS 7 – “CentOS 7 – load a new kernel without rebooting the CentOS 7 server”

Build your own kernel under Ubuntu using mainline (latest) kernel

Here we will show how to build your own kernel under Ubuntu 16/17/18. We are going to use

mainline kernel

because most of the cases when we need to build our own is when we need some new feature presented in the new kernels. So Ubuntu mainline kernels are selected new kernels, which are packed in deb packets for simplicity and can be used to test new features, but they are not supported by Ubuntu teams and you should test them really carefully if you want to use them in production!
The mainline kernels are here: http://kernel.ubuntu.com/~kernel-ppa/mainline/. This is the main address, where you could download the latest kernels and some other legacy one if you have old system.
This howto is based on https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel and https://wiki.ubuntu.com/Kernel/MainlineBuilds – we summarize the commands needed to build your new and latest kernel and show you some typical mistakes and problems during the process.
To show you more information our purpose will be to build the one of the latest kernels with low latency features enabled (Ubuntu has such type of kernel configuration)! And here is one of the most important dependency, which is not explicitly included or even mentioned in most of the tutorials for building your own kernels –

you MUST include new or even latest Linux firmware package

All Linux distros have a package or packages containing files with different firmware for multiple devices supported by the kernel modules. Basically firmware is used by a kernel module and it can be a micro code (program), which is uploaded in the device or just complete the kernel module to function properly with a device. Recent days firmware is like a black box the manufacturer of the devices pack a proprietary code in a firmware blob and the source code is unknown to the community.

The first thing you should do is to choose the kernel version you want to build. We want version 4.17.x as more stable of the latest 4.18, which was released a few days weeks ago (let’s wait for a month after the initial release before using it!).
So the main address is here http://kernel.ubuntu.com/~kernel-ppa/mainline/ and the kernel files, which we are going to use to rebuild are here http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17.19/
Keep on reading!

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:

Tune the screen program (this is not mandatory, but is important to have good scrolling) and start screen.

myuser@srv:~$ echo "termcapinfo xterm* ti@:te@" >> ~/.screenrc
myuser@srv:~$ screen -R xmr-stak

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.

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

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!

Install NVIDIA Cuda on Ubuntu 18.04 LTS (x86_64)

to install NVIDIA Cuda we need the NVIDIA proprietary driver working (and the libraries and files it provides). Ubuntu and most linux distributions come with the open source driver nouveau, but it is with limited performance and capabilities. For gaming and development you will need the official NVIDIA driver, the SDK and many additional proprietary libraries.
This howto is a sort of continuing the Install NVIDIA proprietary drivers on Ubuntu 18.0 LTS (x86_64) where we install the proprietary driver from the unofficial community driven repository “Graphics Drivers” team. This is Personal Package Archives (PPA) repository! So you should check it, too and be careful about this repository as the maintainers say. For completeness will include all the steps to install the NVIDIA proprietary driver (and for more details for this part just read the specific howto we offer above) and Cuda.

Here are the steps to install NVIDIA CUDA on Ubuntu 18.0 LTS (x86_64) with the help of ppa:graphics-drivers/ppa

STEP 1) Update your current repositories, add the new repository, update again and install the NVIDIA driver with the tool ubuntu-drivers

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

As you can see the nvidia 396 driver is going to be installed in our system. You can see all the additional (some of which are dependencies) packages to be installed.
After the reboot you should see something similar in your dmesg:

STEP 2) Install NVIDIA CUDA toolkit. As of writing this howto the CUDA 9.1 will be installed.

It depends on GNU GCC 6, but it will automatically pull it as dependencies (you can include it in the install command line as we did).

You can see all the extra packages you will get – 2G of space is needed and the NVIDIA CUDA 9.1 will be installed (along with GNU GCC 6).

Here you can verify everything is OK:

Install NVIDIA proprietary drivers on Ubuntu 18.0 LTS (x86_64)

The new Ubuntu release is here and as usual it comes with nouveau kernel module for your NVIDIA GPU. Probably this driver is good for everyday office use, but if you like to play games you will need the proprietary driver from NVIDIA for sure! Here are the steps to install the official drivers from NVIDIA with the help of the unofficial community driven repository “Graphics Drivers” team. This is Personal Package Archives (PPA) repository!
DKMS is used for building the NVIDIA kernel module when a new kernel is installed. So you do not have to worry if you update your kernel.
Be careful as it is stated in the repository:

Important: The contents of Personal Package Archives are not checked or monitored. You install software from them at your own risk.

and

You can update your system with unsupported packages from this untrusted PPA by adding …

Still till now no major problems in this repository from its creation and if you just have a home computer and you are a novice in Ubuntu (linux) world you can use this approach of installing NVIDIA proprietary drivers. There is another way of installing the NVIDIA driver from an official source and we are going to cover it soon (coming soon).

STEP 1) Update your system.

Always do this step before installing new software or repositories!

myuser@srv:~$ sudo apt update -y

STEP 2) Add the new repository, which has the nvidia proprietary driver – ppa:graphics-drivers/ppa

myuser@srv:~$ sudo add-apt-repository -y ppa:graphics-drivers/ppa

STEP 3) Update and install the nvidia driver

As you can see we use a tool for installing drivers under Ubuntu:

ubuntu-drivers

which is part of this package “ubuntu-drivers-common” and it should be installed by default if missing just install it with apt (look below for more information).

myuser@srv:~$ sudo apt -y update

Troubleshooting – missing “ubuntu-drivers” in your system just install it with:

myuser@srv:~$ sudo apt install -y ubuntu-drivers-common

Install openssh (sshd) server in Ubuntu 18.04 LTS

Yes, new major system upgrade new rules. If you’ve installed openssh server till Ubuntu 18 (Bionic Beaver) with just the simple command:

myuser@srv:~$ sudo apt-get install -y openssh-server
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package openssh-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'openssh-server' has no installation candidate
myuser@srv:~$

Now it is impossible as you can see. It is strange why they just did not include it as an alias just to prevent you from searching the Net (google?).

So there is a new way of installing OpenSSH server – it is a software collection called “OpenSSH server” and there is a new tool to manage such collections:

tasksel

So you must use tasksel to install OpenSSH server, here is the three command you should use:

sudo apt update
sudo apt install tasksel
sudo tasksel install openssh-server

And their explanation below in steps:

STEP 1) Update your server!

Because you could miss tasksel, it is not installed by default and even after clean install it seems not available before you do an update:

myuser@srv:~$ sudo apt update

STEP 2) Install tasksel

myuser@srv:~$ sudo apt install tasksel

STEP 3) Install OpenSSH server with tasksel

You are going to enter an console based graphic setup showing you the installation of the software collection “OpenSSH server”

myuser@srv:~$ sudo tasksel install openssh-server

Here is what is going to see after the above command:

main menu
tasksel installs openssh-sftp-server

main menu
tasksel installs openssh-server

* Throubleshooting – no tasksel packet!

Just DO NOT skip STEP 1) – update your package lists!!!

myuser@srv:~$ sudo apt install tasksel
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package tasksel

Install Ubuntu Desktop 18.04 LTS on a PC with existing windows 10 and linux

This tutorial will show you the simple steps of installing a modern Linux Distribution – Ubuntu Desktop 18.04 LTS. Here we present the more advanced setup installation, when you have already had installed operating systems, so this installation will add Ubuntu 18.04 LTS to our two existing ones – Microsoft Windows 10 Professional and Fedora Workstation 28. So we have 3 hard disks – one is NVME, the other two are SSDs and we want to install our Ubuntu 18.04 to the first disk – “sda” in this case. Our first SSD has two partitions, which we will remove and make new disk layout for the Ubuntu installation with three partitions.
Ubuntu Desktop 18.04 LTS comes with the following software:

  • Xorg X server – 1.19.6
  • GNOME (the GUI) – 3.28.1
  • linux kernel – 4.15.0
  • linux-firmware – 1.173
  • QT – 5.9.5
  • libc – 2.27
  • gnu gcc – 7.3.0
  • coreutils – 8.28
  • python2.7 (default) – 2.7.15
  • python3 – 3.6.5
  • perl – 5.26.1
  • apt – 1.6.1
  • cups – 2.2.7

We used the following ISO for the installation process – Ubuntu 18.04 LTS (Bionic Beaver):

http://releases.ubuntu.com/18.04/ubuntu-18.04-desktop-amd64.iso

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

STEP 1) Change to “Install Ubuntu” and hit enter.

To install Ubuntu from your DVD or USB you must boot from it, so change your BIOS accordingly – first boot devide should be the DVD or USB drive with Ubunto installation. If you do it successfully you would see the screenshot below.

Install Ubuntu 16.04 LTS on a PC with existing windows 10 and linux

This tutorial will show you the simple steps of installing a modern Linux Distribution – Ubuntu Desktop 16.04 LTS (in fact the version presented here is 16.04.4 Desktop LTS). Here we present the more advanced setup installation, when you have already had installed operating systems, so this installation will add Ubuntu 16.04 LTS to our two existing ones – Microsoft Windows 10 Professional and Ubuntu 17.10. So we have 4 disks – one is NVME, the other three are SSDs and we want to install our Ubuntu 16.04 to the third disk – “sdc” in this case. Our third SSD do not have partitions or any data, so we can use the whole device.
Ubuntu Desktop 16.04 LTS comes with the following software:

  • Xorg X server – 1.19.5
  • unity (the GUI) – 7.4.5
  • linux kernel – 4.13.0
  • linux-firmware – 1.157.17
  • QT – 5.5.1
  • libc – 2.23
  • gnu gcc – 5.4.0
  • coreutils – 8.25
  • python2.7 (default) – 2.7.12
  • python3 – 3.5.1
  • perl – 5.22.1
  • compiz – 0.9.12.3
  • apt – 1.2.25
  • cups – 2.1.3

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.
