This is a quick guide on how to use T-Rex on your Ubuntu 20.04 mining rig to allow your NVidia 1080 Ti cards to mine Ethereum in 2021.
On the rig
Open a Terminal
sudo bash
Enter your password
mkdir /tacticalware
cd /tacticalware
If you have Cuda 10 installed, download the following, otherwise find the one for your Cuda version
wget https://github.com/trexminer/T-Rex/releases/download/0.19.5/t-rex-0.19.5-linux-cuda10.0.tar.gz
Once it is downloaded
tar -zxvf t-rex-0.19.5-linux-cuda10.0.tar.gz
cp ETC-2miners.sh tacticalware-eth.sh
nano tacticalware-eth.sh
Now modify the contents of the file. I suggest replacing the mining site, and wallet address. My file looks like this:
./t-rex -a ethash –coin eth -o stratum+tcp://us1.ethermine.org:4444 -u 0xb6c1807520Fc60e39a29cD02a859c652B2910DB8 -w tacticalware
Note that there is a double dash before –coin and –fork. Sometimes your browser will show them as a double dash, sometimes it shows as a single long dash. they are double dashes
Save the file
Exit
Now you can launch it by running
./tacticalware-eth.sh
It will begin to mine. To monitor it you can do it through a web browser. Simply look for the address when the miner begins
The address will look something like this, and be displayed right when you begin mining
When you browse to that site you will see something that looks like this:
That’t It. You are mining successfully. Thanks for reading
