Mining monero through Tor in Ubuntu 14.04

Mining Monero through Tor can be easly done using proxychains-ng (also called proxychains4). sudo proxychains4 /opt/cpuminer-multi/minerd -a cryptonight -o stratum+tcp://mine.moneropool.com:3333 -u YOUR_WALLET_ADDRESS -p x
Instructions how to install proxychains-ng on ubuntu are here and how to cpu miner for monero are here.

Testing if it works

To check if it works, I will assume we use the following moneropool. First lets check IP address for the pool address: mine.moneropool.com

	nslookup mine.moneropool.com
	Server: 127.0.1.1
	Address: 127.0.1.1#53
	Non-authoritative answer:
	Name: mine.moneropool.com
	Address: 54.75.230.12
	Name: mine.moneropool.com
	Address: 54.75.230.15
	Name: mine.moneropool.com
	Address: 54.78.196.115
	Name: mine.moneropool.com
	Address: 54.75.230.11
	Name: mine.moneropool.com
	Address: 54.78.210.153
	Name: mine.moneropool.com

Note that you may have different IP addresses, as the pool is on the Amazon cloud and the IP can be different. Having the IPs lets use iftop to monitor our outgoing connections. If you dont have iftop, install itsudo apt-get install iftop First, lets check the iftop (run using sudo iftop) window when we run the minred miner without proxychains and torsudo /opt/cpuminer-multi/minerd -a cryptonight -o stratum+tcp://mine.moneropool.com:3333 -u YOUR_WALLET_ADDRESS -p x When using the minerd without tor, we should see Amazon servers in the iftop window since the miner connects directly to the pool:

As can be seen, some of the servers were found in the nslookup for the mine.moneropool.com.


Now, lets see what happens when we use proxychains:udo proxychains4 /opt/cpuminer-multi/minerd -a cryptonight -o stratum+tcp://mine.moneropool.com:3333 -u YOUR_WALLET_ADDRESS -p x

The Amazon's servers are gone from the iftop, since the minerd connects to the Amazon servers using our tor. Instead of Amazon names, we see an input tor node.

Install and test proxychains-ng (or proxychains4) in Ubuntu 14.04

To download, compile and set-up do the following:

	# if you havent done it yet, please download the tor-browser and start it
	# https://www.torproject.org/download/download-easy.html.en
	wget https://www.torproject.org/dist/torbrowser/5.0/tor-browser-linux64-5.0_en-US.tar.xz
	tar xf tor-browser-linux64-5.0_en-US.tar.xz
	# download the source of proxychains-ng
	git clone https://github.com/rofl0r/proxychains-ng.git
	cd proxychains-ng
	# configure and install
	./configure --prefix=/usr --sysconfdir=/etc
	make
	sudo make install
	sudo make install-config # installs /etc/proxychains.conf
	# I've noticed that is better to change one default line
	# in /etc/proxychains.conf to what tor browser (i.e. firefox)
	# is using as can be seen here: http://i.imgur.com/pKuqHPU.jpg
	sudo gedit /etc/proxychains.conf
	Chanege last line in the file:
	from “socks4 127.0.0.1 9050” to “socks5 127.0.0.1 9150”
	# to test if proxychains4 goes through tor
	# we can do two simple tests. For this we need elinks and iftop
	sudo apt-get install elinks iftop

view raw setup_proxychains-ng.sh hosted with ❤ by GitHub

To test the proxychain
For example using iftop. Run iftop in a second terminal window: sudo iftop Now run elinks https://ipleak.net/ and check what you see in both the elinks and iftop. You should see your real IP in the ipleak test, and iftop should show that you are directly connecting to ipleak.net as shown below:

Now do the same through proxychain:proxychains4 elinks https://ipleak.net/

And we should see that iftop shows we are connection to an entry tor node, and elinks should show are tor ID, instead of real one.

Ubuntu 14.04: compile CPUMiner / minerd (forked by LucasJones & Wolf) for Monero mining

To CPU mine Monero in a moneropool it is suggested to use cpuminer called minerd. To compile it on Ubuntu 14:04 or later, the following dependencies are required:

sudo apt-get install build-essential autotools-dev autoconf libcurl3 libcurl4-gnutls-dev

	# get git to install it
	sudo apt-get install git
	# dependencies
	sudo apt-get install build-essential autotools-dev autoconf libcurl3 libcurl4-gnutls-dev
	# download latest version
	git clone https://github.com/wolf9466/cpuminer-multi
	cd cpuminer-multi/
	# compile
	./autogen.sh
	CFLAGS="-march=native" ./configure
	make
	#install
	sudo make install

view raw compile_monero.sh hosted with ❤ by GitHub

Example use: minerd -a cryptonight -o stratum+tcp://mine.moneropool.com:3333 -u YOUR_WALLET_ADDRESS -p x

Once you start mining using moneropool, you can check your status at anytime on their front page using your xmr address:

Just remember that their pending balance updates after a while. For me it took maybe 1-2h before I saw any pending balance after I had started mining. Hash rate updates very quickly though.


Just in case you get the errorconfigure.ac:133: error: possibly undefined macro: AC_MSG_ERROR
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
it means that you haven't install libcurl4-gnutls-dev.

LG 43UF770 4K TV with gtx 960 running at 4K at 60Hz and chroma 4:4:4

This is complementary info to the one in here. I have LG 43UF770T and Gigabyte GTX 960 G1 Gaming 4GB. The PC is set to 4K@60Hz and connected to the tv using HDMI 1 port. Only this port supports HDMI ULTRA HD Deep Colour in this tv. By default HDMI 1 icon is HDMI and HDMI ULTRA HD Deep Colour is off as written above. This results in chroma 4:2:0. I changed the setting as per instructions here, i.e. HDMI 1 port icon to PC and HDMI ULTRA HD Deep Colour to On. The nvidia settings are shown below.

To test the chroma for the default setup and the new one I used chroma torture test.

The results are here:

As can be seen, the top red, middle blue and bottom text is unreadable with the default tv settings on HDMI 1 port. With the new settings, everything is clear.
