SETTING UP A CRON JOB FOR SCRAPING THROUGH NORDVPN

If any of you are like me, you find that your scrapers are limited from time to time by the number of requests you can make to a website within a certain period of time. To get around this, you can setup python scraping through nordvpn to automatically change of your IP addresses. There are other programs as well…Tor allows this for free. I personally use NORD, because I have had better performance and the cost is a few dollars per month not to have to deal with the headaches.

So I setup my cron job as follows
Every hour (9:00, 10:00, etc) it will connect to Nord
5 Mins past every hour (9:05, 10:05, etc) it will run my scraper
15 Mins past every hour (9:15, 10:15, etc) it will disconnect from Nord
30 Min past every hour (9:30, 10:30, etc) it will reconnect to Nord (this usually gives it enough time to get a different IP. If you log back in immediately you will attach to the same server. This fixes that.
35 Mins past every hour (9:35, 10:35, etc) it runs the scraper
45 Mins past every hour (9:45, 10:45, etc) it disconnects from Nord

To set this up I run the following

sudo bash

Enter Password

crontab -e

Select 1 (for nano)

Scroll to the bottom of the file and add the following:

0 * * * * /usr/bin/nordvpn connect >> /home/user/cron.log 2>&1
5 * * * * python3 /home/user/scraper.py >> /home/user/cron.log 2>&1
15 * * * * /usr/bin/nordvpn d >> /home/user/cron.log 2>&1
30 * * * * /usr/bin/nordvpn connect >> /home/user/cron.log 2>&1
35 * * * * python3 /home/user/scraper.py >> /home/user/cron.log 2>&1
45 * * * * /usr/bin/nordvpn d >> /home/user/cron.log 2>&1

Save the file, exit, and you are all set. Your scraper will run as directed

Easy way to fix the following errors

Installing AMD Drivers on Ubuntu 18.04 has been a pain…until now. To fix the following errors you have to simply do the following

ERRORS:

The following packages have unmet dependencies:

amdgpu-pro : Depends: libvdpau-amdgpu-pro but it is not going to be installed

              Depends: clinfo-amdgpu-pro but it is not going to be installed

amdgpu-pro-dkms : Depends: dkms (>= 1.95) but it is not going to be installed

amdgpu-pro-lib32 : Depends: libdrm-amdgpu-pro-amdgpu1:i386

                    Depends: libgbm1-amdgpu-pro:i386

                    Depends: libgl1-amdgpu-pro-glx:i386

Etc, etc, etc………

To fix it, at the command line, type the following:

sudo dpkg –add-architecture i386

Now try the install again:

sudo ./amdgpu-pro-install -y

Installing Teamviewer on Ubuntu Server

How-To guide for installing and running Teamviewer on your Ubuntu Mining Rig

This is the quick and dirty to get it up and running.  I find that running Teamviewer on my Ubuntu Mining Rigs helps me manage them on the fly.  For this guide you will replace the home directory named tacticalware with the name of your home directory.  The rest of the commands will work as they are listed.

From a command prompt run the following commands:

sudo bash

mkdir /home/tacticalware/teamviewer

cd /home/tacticalware/teamviewer

wget https://download.teamviewer.com/download/linux/teamviewer-host_amd64.deb

dpkg -i teamviewer-host_amd64.deb

The installation will fail

Now run:

apt-get -f install

y

After it installs then run

teamviewer setup

Enter your username

Enter your password

Log into your email, and find the Teamviewer email

Allow/Add the device

And now you can log into your server using Teamviewer

 

Installing XMR-STAK on Ubuntu with NVidia 1080TI

How-To guide for installing XMR-STAK on Ubuntu 16.04.04 for Mining LOKI

I prefer linux (more specifically Ubuntu) for mining, and have preferred linux since I began mining in 2012/2013.  I was finally fed up with Windows 10 mining of Loki after the most recent set of Windows updates broke several of my rigs.  So I used a small ubuntu rig that I used for testing, and was able to install the XMR-STAK app onto it.  As happy as ever to be able to mine Loki now with Ubuntu, I thought I should put together this quick guide and hope that it may be beneficial to others.  Some of the steps are from github, some are from other sites, some I had found myself.  This is a central place to get you up and running without having to look too far.

For this guide I am assuming you already have a mining rig built with the following:

Ubuntu 16.04.04

NVidia 1080TI Cards

Loki Wallet already downloaded, installed, and the wallet address ready

I am going to run the commands logged in as sudo to make this quick and easy

Now, onto the guide:

sudo bash

apt-get install libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev screen

mkdir /miner && mkdir /miner/drivers

git clone https://github.com/fireice-uk/xmr-stak.git

mkdir xmr-stak/build

cd xmr-stak/build

cmake ..

make install

cd /miner/drivers/xmr-stak/build/bin/

./xmr-stak

You will need to insert a port for monitoring the progress.  I use port 30131 and press Enter

Next type in cryptonight_heavy and press Enter

For the pool address, I use loki.ingest.cryptoknight.cc:7733  press Enter

Your username will be your wallet address, for example

LChtjHqr29p5FojLdMtcUW5ApLWyQHH5j4366V78YECEjUkgK99Y7uLDVLpHjXpYM3UcZ39FFL5Gvd4debF95mcJHbnx5ke

The password will be your worker name.  For example mine is Miner23

Your Rig Identifier can be empty, so just press Enter

Input N for TLS and press Enter

Insert N for Nicehash and press Enter

Input N for multiple pools and press Enter

Select Yes when prompted

Mining will begin!

Once you see it mining properly, hit CTRL + C to cancel the mining.  You will want to run it in screen, so you can disconnect from the terminal and the miner will continue to run. To do that run:

screen ./xmr-stak

It will run and you can now disconnect from your putty session or whatever way you are logged in.  If you want to reconnect to your terminal at any time, run the following and you can see your miner running

screen -r

That’s it!  Thanks for reading!

Mining using AMD RX480 Nitro & RX580 Nitro on Ubuntu

How-To Guide for mining with the AMD Series cards on Ubuntu Server 16.04.04

This guide assumes you already have the Rig built, and Ubuntu Server 16.04.04 installed on it.  Once the rig boots to the terminal, this guide begins.  I am going to install everything as root, yes there are reasons why you should and should not do it that way.  I just prefer to get it up and running as quickly as possible.  I do not store anything on my miners, and you should not either.  Keep your wallets off your mining rig.  Keep your coins secure.  Keep your miners with limited data on them, so you can wipe and reinstall on the fly if you need.

Once Install Ubuntu 16.04 Server is installed type the following in bold as they appear

sudo bash

ifconfig

apt-get install openssh-server

Now you can use your laptop/desktop and log into the server.  Download putty, and connect to the server via it’s IP or Server Name.  My Username Name is tacticalware, so you can change everywhere you see tacticalware listed, you will change that to the username of the account you are logged in as

sudo bash

apt-get update

apt-get upgrade

apt install git screen nmap ncdu busybox inxi clinfo links unzip python xorg xserver-xorg-legacy xserver-xorg-video-dummy libcurl3

systemctl disable lightdm.service

mkdir /miner && mkdir /miner/drivers && mkdir /miner/drivers/amd && cd /miner/drivers/amd

Download the drivers from on a laptop

Now use Winscp on the laptop to copy the drivers to the Ubuntu Server

cd /home/tacticalware/ && cp ./* /miner/drivers/amd/ && cd /miner/drivers/amd/

The version I downloaded and used was amdgpu-pro-17.30-458935.tar.xz … you will need to change that part of the name to the version you have

tar -Jxvf amdgpu-pro-17.30-458935.tar.xz && cd amdgpu-pro-17.30-458935 && ./amdgpu-pro-install -y

usermod -a -G video $LOGNAME

Download the SDK from here to your laptop

Winscp it to the server

Move the SDK from your home directory to /miner/drivers/amd

tar xf AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2 && ./AMD-APP-SDK-v3.0.130.136-GA-linux64.sh

reboot

Log back into the server now

sudo bash

clinfo

clinfo | grep compute

nano /etc/X11/Xwrapper.config

delete the last line:
allowed_users=console

insert at end of file:

allowed_users=anybody
needs_root_rights=yes

Create a new file for operating without a monitor:

nano /etc/X11/xorg.conf

Save the file and exit

cd /home/tacticalware/

nano .bashrc

Add the following at end of .bashrc

export DISPLAY=:0

Save the file and exit

nano /etc/profile

Add the following at end of /etc/profile:
export XAUTHORITY=~/.Xauthority

Save the file and exit

nano .xinitrc

#!/bin/bash
DISPLAY=:0 && xterm -geometry +1+1 -n login

Save the file and exit

cd /miner/drivers/ && mkdir claymore && cd /miner/drivers/claymore

On your laptop download Claymore from

https://drive.google.com/drive/folders/0B69wv2iqszefdmJickl5MF9BOEE

Winscp it to the mining rig

Move it to /miner/drivers/claymore

tar zxvf the file

nano zec.sh

#!/bin/sh
xinit &
sleep 5
export GPU_FORCE_64BIT_PTR=1
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100

./zecminer64 -zpool us1-zcash.flypool.org:3333 -zwal t1QYSbLrnbECDu76KDcvoyjBbbhsuWxZXWm.miner20 -zpsw x

Save the file and exit

chmod +x zec.sh

Update config.txt file, also modify epool and dpool with your wallet info and remove default dev info

Save the files

screen ./zec.sh

Now you will want to watch for issues

You can close putty whenever, it does not need to be open for your miner to work, and if you want to reattach a screen, log back in using putty and type

screen -r
