RESTORE MINING WALLETS IN WINDOWS 10

The most recent Windows 10 update, went through my computer and started tagging many of my crypto wallets as threats, then it automatically quarrantined them. HUGE FAIL by Microsoft. I did not want their Defender app enabled after the update. I did not want it to scan my system.

To restore your newly quarrantined items, do the following:

Open Windows Security
Select Virus & threat protection
Click Protection history
In the list of all recent items, filter the Quarantined Items
Click all of the newly identified and restore

That’s it! Thanks for reading

REMOTE SUPPORT THROUGH CHROME REMOTE DESKTOP

Teamviewer has been a constant headache in 2020. So I have had to find a teamviewer replacement…and have found Chrome Remote Desktop. So far my experience has been good. Quick, easy install. I can still remotely manage my mining rigs. This guide shows how I connect to a system that runs during the day for a dedicated user (who owns it), and mines at night. When he has an issue, he contacts me and we setup a Chrome Remote Desktop support session using the following excerpt from this link https://support.google.com/chrome/answer/1649523?co=GENIE.Platform%3DDesktop&hl=en

Share your computer with someone else

You can give others remote access to your computer. They’ll have full access to your apps, files, emails, documents and history.

  1. On your computer, open Chrome.
  2. In the address bar at the top, type remotedesktop.google.com/support, and press Enter.
  3. Under “Get Support, “ click Download Download page.
  4. Follow the onscreen directions to download and install Chrome Remote Desktop.
  5. Under “Get Support,” select Generate Code.  
  6. Copy the code and send to the person you want to have access to your computer.
  7. When that person enters your access code on the site, you will see a dialog with their e-mail address. Select Share to allow them full access to your computer.
  8. To end a sharing session, click Stop Sharing.

The access code will only work one time. If you are sharing your computer, you will be asked to confirm that you want to continue to share your computer every 30 minutes.

USING ‘SCREEN’ ON A HEADLESS MINER

To set the stage, my mining rigs are setup on Ubuntu 20.04, with NVidia 1080Ti Cards, and they are headless systems. On these systems, I use Putty to connect to them, and run them. You will notice that when you close putty, your miner will stop mining. Which can be a pain, because who wants to always have a Putty connection to their miner, especially when it is a headless system.

A fun little program that I have used for years and never thought of mentioning, is called Screen. Screen allows you to run your headless mining system, without putty being constantly attached, or having a keyboard / mouse / monitor attached.

To enable screen, you can do the following once you are logged in through putty
sudo bash
apt-get update
apt-get install screen
If you are running Ubuntu 20.04 you may find that it is already installed. If it is installed, to run it, simply do the following
screen ./program-name
and the program will run

For me I use it to run my custom mining scripts, so I will cd to the directory, and run
screen ./etc.sh
The mining software will start up, and I can then close Putty, and the rig will continue to mine…..

If at any time you want to reconnect to your miner to see the progress:
Open Putty
Login
Type screen -r
Press Enter
Your screen will reconnect

MINING ETC ON UBUNTU WITH NVIDIA 1080TI

Recently I had to change the software on my rig. My rig is mining ETC on Ubuntu with NVidia 1080TI cards. I had to change it because claymore was not working the way it should with the site ethermine, hence the need to change mining software from claymore to ethminer. The following guide is how i did it.

Login to the headless rig
sudo bash
cd /
mkdir /miner
cd /miner
wget https://github.com/ethereum-mining/ethminer/releases/tag/v0.18.0

Once it downloads you then run
tar -zxvf *.gz
The software will unpack

cd bin
wget https://tacticalware.com/downloads/etc-ethminer.txt
mv etc.txt etc.sh
chmod +x etc.sh
nano etc.sh
Change the wallet address to your wallet
Save the file and Exit
./etc.sh

You should now be mining. Be sure to look at https://etc.ethermine.org/ and monitor your wallet to verify that it is sending data back and forth to the site. It should take about 15 minutes to show up initially, so be patient.

INSTALLING CUDA ON UBUNTU SERVER 20.04

  • Mining

In the past, installing CUDA onto Ubuntu Servers, used in mining, was a large undertaking. With the latest release of Ubuntu, everything has changed. Thankfully. Now we are able to easily go through the steps of installing cuda on ubuntu server 20.04. The steps below outline what you will need to do to make this work. I have had success installing either before, or after, I already have the 1080ti drivers on the system. It may not be the same in the future, but as of this writing today, all you have to do are the few steps below.

Open a Terminal
sudo bash
apt-get update
apt install nvidia-cuda-toolkit
y

Cuda will now run the installation. It will take a while, so sit tight. Once it is done installing cuda on ubuntu server 20.04…you are done. Enjoy!

Data Leakage From Your Home/Mining Network

How to Scan and Identify Issues at the Perimeter of your Network

A question that has been asked multiple times is how do I know what my risk is at the border of my network….Miners and Wallet holders are concerned due to the increased risk of compromised wallets, and compromised mining rigs. So to answer this I will send you to a few quick places to do a spot check on your exposure.

  1. Find out your external IP by visiting
  2. Sign up for an account at Shodan.io
  3. Place your External IP in the search box on Shodan.io and see the results of your network. If there are known CVEs (vulnerabilities) on the open ports of your network, it will be displayed here. You MUST fix the issues identified by the CVEs
  4. Run a scan from outside of your network. Meaning, go visit your cousin, or some family member. Hop onto their network, and run the following nmap scan against your network. This scan is a lot more detailed, and will be a longer, slower process. But the resulting open ports and banners will give you more places to look in your quest to secure your network. Replace the xxx.xxx.xxx.xxx with your External IP. nmap -sV –script=banner xxx.xxx.xxx.xxx

There you have it. Some quick tools to see what the perimeter of your network looks like. Remember to follow up on every open port, banner, and CVE…lock your system down now before it is compromised.
