Ethereum Mining with NVIDIA Graphics Cards and Ubuntu

USB flash drive ISO image for Ethereum mining with NVIDIA graphics cards and Ubuntu GNU/Linux (64-bit Intel/AMD (x86_64)).

Ubuntu NVIDIA

Press the 👁️ "Watch" button to get updates. Do not forget the 🌟 "Star" button 😀

🚨Use at your own risk. Hope to help you. Do not make me responsible for broken hardware. 🚨

Introduction

  • This ISO image is based on 🐧Ubuntu 16.04.2 LTS (Server).
  • KISS, keep it simple, stupid. Only the most necessary included. No 💩 bullshit.
  • NVIDIA drivers version 381.22 and CUDA 8 are installed.
  • Genoil's CUDA miner ethminer (ethminer-genoil) already compiled and executable.
  • Claymore's CUDA miner ethdcrminer64 is also included.
  • Already configured to participate in the ethermine ethereum mining pool.
  • The installation is optimized for operation without monitor (headless).
  • No hard disk drive (HDD/SSD) required. Installation on USB flash drive.
  • Created and tested with two NVIDIA GTX 1060s.

Installation

If you do not trust me and do not want to use the image, you will find all configuration files and scripts in the files folder. You only have to install an Ubuntu Linux with all the drivers and tools yourself.

If you want to get started quickly, simply use the pre-configured ISO image (contains the shell scripts, tools, and all necessary drivers).

Download

Download the ISO image via BitTorrent (ethereum-ubuntu-nvidia-miner.torrent). Compressed 4.7GB, unzipped 30.7GB.

Download

MD5

It is recommended to test that the image is correct and safe to use. The MD5 calculation gives a checksum, which must equal the MD5 value of a correct ISO image.

Copy

  1. Unzip the 7zip file ethereum-ubuntu-nvidia-miner.img.7z.
  2. Copy the image ethereum-ubuntu-nvidia-miner.img to a 32GB USB flash drive.

Larger USB flash drive should also work. I use the "Sandisk 32GB Ultra Fit USB 3.0 Flash Drive".

The copy can be done with dd. ⚠️ The copy lasts long. Be patient.

How this works exactly is explained to you here: https://wiki.archlinux.org/index.php/USB_flash_installation_media#Using_dd

Under 🍎 macOS it works like this:

Identify the disk (not partition) of your USB flash drive e.g. disk3:

nils@macbookpro ~ $ diskutil list

Unmount your USB flash drive:

nils@macbookpro ~ $ diskutil unmountDisk /dev/disk3

Copy the image to your USB flash drive:

nils@macbookpro ~ $ sudo dd bs=1m if=Downloads/ethereum-ubuntu-nvidia-miner.img of=/dev/rdisk3

Btw. rdisk3 (with r) not disk3 is not a write error.

Set Up

Mainboard

Set the primary graphics output to on one of your NVIDIA cards. Disable Secure Boot (UEFI) and boot from the USB flash drive.

Login

The network configuration is done by DHCP. Look in your router which IP your miner has.

Connect via SSH with your miner.

nils@macbookpro ~ $ ssh prospector@minerIP

Credentials. Password should be changed (passwd):

  • 👤 Username: prospector
  • 🔑 Password: m1n1ng

Update

Mistakes happen. The errors and improvements are posted in this GitHub repository. Get the latest scripts:

prospector@mine ~ $ curl "https://raw.githubusercontent.com/Cyclenerd/ethereum_nvidia_miner/master/files/update.sh" -o ~/update.sh
prospector@mine ~ $ bash update.sh

For security delete my public SSH keys (also performed by the update.sh script):

prospector@mine ~ $ rm .ssh/authorized_keys

Mine

After a minute uptime, a script (screen) starts automatically in the background, which starts the mining.

prospector@mine ~ $ crontab -l

# run screen after reboot
@reboot sleep 60 && /usr/bin/screen -d -m

Enter mine to get it in the foreground:

prospector@mine ~ $ mine

Use key combination Ctrl + a, and subsequently pressing a key to execute one of the commands given below:

  • n : switches to the next available console
  • p : switches back to the previous console
  • c : creates a new virtual Bash console
  • d : detatches the current screen sessions and brings you back to the normal terminal

htop nvidia-smi etherminer

miner.sh

The miner.sh script starts automatically (mine console). In this script you have to make adjustments:

prospector@mine ~ $ nano -w miner.sh
  • Enter your public Ethereum address: MY_ADDRESS
  • Enter your mining rig name: MY_RIG
  • Specifies maximum power limit in watts: MY_WATT

X11 Configuration with Fake Monitors.

First of all you should run the nvidia-config.sh script and reboot. This script generates an xorg.conf (/etc/X11/xorg.conf) with faked monitors (for each of your cards). You need to run this everytime you add or remove cards.

prospector@mine ~ $ bash nvidia-config.sh
prospector@mine ~ $ reboot

Fine Tuning

To pull the last MH/s out of your cards, you should overclock.

Overclocking

With nvidia-overclock.sh (nvidia-settings)

Run the nvidia-overclock.sh to adjust the memory and graphics clock. The settings are lost after a restart. You have to repeat it.

prospector@mine ~ $ bash nvidia-overclock.sh

For safety I did not add it in the autostart (miner.sh). Sometimes you exaggerate when overclocking, and you'll be glad if a simple reboot helps.

You should experiment with the values and adjust the values in the script. I wish you success 🤓

prospector@mine ~ $ nano -w nvidia-overclock.sh

Why not use nvidia-smi?

nvidia-smi does not work with my cards.

prospector@mine ~ $ nvidia-smi -i 0 -ac 4004,1987
Setting applications clocks is not supported for GPU 0000:01:00.0.
Treating as warning and moving on.
All done.

No idea if this is a 🐛 bug. Have tried several drivers. Forums are full of bug reports. With nvidia-settings I have no problems.

You can try it with your cards. Here the text from the help:

-ac, --applications-clocks=MEM_CLOCK,GRAPHICS_CLOCK

Specifies maximum <memory,graphics> clocks as a pair (e.g. 2000,800) that defines GPU's speed while running applications on a GPU.

Other things you should do

Set timezone:

prospector@mine ~ $ sudo dpkg-reconfigure tzdata

Run sensors-detect to search for sensors and to generate the necessary kernel modules:

prospector@mine ~ $ sudo sensors-detect

Generating new SSH daemon keys:

prospector@mine ~ $ sudo ssh-keygen -q -b 8192 -t "ed25519" -f "/etc/ssh/ssh_host_ed25519_key"
prospector@mine ~ $ sudo ssh-keygen -q -b 8192 -t "rsa" -f "/etc/ssh/ssh_host_rsa_key"

Update ethminer-genoil:

# Install CUDA without the driver!!!
prospector@mine ~ $ sudo apt-get install -y cuda-command-line-tools-8-0
# Compile ethminer
prospector@mine ~ $ cd cpp-ethereum/
prospector@mine cpp-ethereum $ git pull
prospector@mine cpp-ethereum $ cd build/
prospector@mine build $ cmake -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-8.0 -DBUNDLE=cudaminer ..
prospector@mine build $ make -j8

Monitoring

Of course, with SSH. But munin and the lighttpd web server are also installed. You can use it to access statistics pages.

http://minerIP/munin

Here you can find diagrams of the sensors, etc.

munin

VNC

Start x11vnc server.

prospector@mine ~ $ x11vnc

Enter the IP address and display in VNC Viewer to establish a direct connection. For example:

minerIP:0

x11vnc

Fail2ban

Fail2ban is installed. The program monitors logins via SSH. Too many false logins from an IP and the IP is blocked. At each start (reboot) and block you will receive an e-mail. You should check your e-mails from time to time.

prospector@mine ~ $ mutt

Help 👍

If you have found a bug (English is not my mother tongue) or have any improvements, send me a pull request.

Leave a Tip 🙏

With the image, you can immediately mine Ethereum. Do not spend long time searching and researching.

I would be happy about a small donation.
