How To Mine Your First Litecoins For Free

Before we start with the guide, I would like to point out that if you want to get serious, you need the invest some money.  This is what I would recommend and run myself (I have 4 rigs):

3 * ASUS R9 280X-DC2T-3GD5 Graphics Cards 
1 * ASRock MB-970EX4 Socket AM3+/ AMD 970
1 * AMD Sempron 145 Processor
1* Corsair Professional Series AX 1200 Watt
1* Kingston Hyper X Blu 4 GB 
PCI-E PCI Express 16X Riser  

The 280x graphics cards currently offer the best bang for the buck and yield 740-760 khs each.


Litecoin is scrypt-based


But now back to the actual topic: i.e. how to mine your first Litecoins for free. ;)

Requirements

  • sign up for a mining pool such as LTCRabbit and create a worker (LTCRabbit: My Account > My Workers > Add New Worker)
  • an azure trial account
  • approx. 15 min of your time
The Azure Account

You need a credit card to qualify for the trial period of 1 month (Link: Trial). Note that the subscription will end automatically. (You can even sign up twice with the same card ;) )

After you have access, click on + new - compute - virtual machine -quick create.

==> choose Ubuntu server 12.04 LTS + Extra large

Back to your machine

Download Putty and open it. Link.

Host: yourdnsname.cloudapp.net (the one you've chosen when creating the virtual machine)
User: azureuser
Password: yourpassword (password you've set before)

You will be presented with a Linux terminal.

Issue the following commands
sudo su
apt-get install build-essential libcurl4-openssl-dev
wget http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2.tar.gz
tar xzf pooler-cpuminer-*.tar.gz
cd cpuminer-*
./configure CFLAGS="-O3"
make
./minerd --url=stratum+tcp://stratum+tcp://eu.ltcrabbit.com:3333 --userpass=username.worker:password --background

Of course you need to adjust the settings (e.g. "username.worker:password"). Login to LTCRabbit  and you will be able to see your KH/S rate if everything is set up right.

Now create another virtual machine and repeat the above steps.

Any questions? Leave me a comment!

Open a terminal and execute the following commands sudo apt-get install auto-apt build-essential sudo auto-apt update-local sudo auto-apt update sudo auto-apt updatedb Now make sure you got both tcl8.5-dev and tk8.5-dev installed sudo apt-get install tcl8.5-dev tcl8.5 sudo apt-get install tk8.5-dev tk8.5 Some users are reporting problems on Ubuntu 14.04. sudo apt-get install tcl8.6-dev tcl8.6 sudo apt-get install tk8.6-dev tk8.6 libgcj15-dev The 'x' refers to the current release: e.g. 4.9.tgz download scid vs pc: http://sourceforge.net/projects/scidvspc/files/source/scid_vs_pc-4.9.tgz/download tar -xzf scid_vs_pc-4.xx.tgz cd scid_vs_pc-4.x sudo auto-apt run ./configure sudo auto-apt run make sudo auto-apt run make install

Automatically Reconnect WIFI (Debian, Ubuntu etc.)

The Problem For several reason I do not have access to LAN and thus have to rely on WIFI for my mining rigs. It is fine for most of the time, but the shit hits the fan, when the connection drops for one reason or another. The Solution #!/bin/bash wlan=`/sbin/ifconfig wlan1 | grep inet\ addr | wc -l` if [ $wlan -eq 0 ]; then service network-manager restart else echo WIFI IS UP fi Note: It's either wlan0 or wlan1. Check with sudo ifconfig . Save the script and make it executable. sudo chmod +x filename.sh Now there are several ways of making sure that our script is being executed every x minutes. The easiest way of accomplishing that I think is by using the command watch . sudo su watch -n 600 sh filename.sh What it does is execute our filename.sh script every 600 seconds. Or you implement a so called cron job   sudo crontab -e Add the following PATH=/usr/sbin:/usr/bin:/sbin:/bin */5 * * * * sh /home/username/filename.sh */5 * * * * means that
