Litecoin Mining for Funtoo
Litecoin mining is a fun and easy way that you can help support the Funtoo Linux project. Litecoin is a virtual cryptographic currency that is generated using CPUs and video card GPU computational power, and can be converted into a traditional currency like US dollars. Typically, it is mined by pools of computers, and Funtoo is part of the ozco.in pool.
Here's how to get started and convert your idle CPU power into a contribution to the Funtoo Linux project.
The "miner" is the program that performs the computation to generate litecoins. It receives blocks from a server, which it performs computations on. Miners are designed to run continually in the background, where they use up idle CPU only, and will not impact the speed of your system. A significant contribution to Funtoo Linux is only realized when miners are run continually for days and weeks -- so running a miner for an hour or so is typically not effective.
Use your favorite CFLAGS to compile the cpuminer program. Note that -O2 seems to work much better than -O3:
# wget https://github.com/downloads/pooler/cpuminer/pooler-cpuminer-2.2.3.tar.gz # tar xf pooler-cpuminer-2.2.3.tar.gz # cd cpuminer-2.2.3 # ./configure CFLAGS="-O2 -march=corei7" # make -j4 # cp minerd /usr/local/bin
Installation using Portage
This method will use CFLAGS from /etc/portage/make.conf. Note that -O2 seems to work much better than -O3.
# emerge pooler-cpuminer
Set up go.sh
Create the following go.sh script to start the miner:
#!/bin/bash threads=$(grep -c "^processor" /proc/cpuinfo) while true; do minerd --algo scrypt -s 45 --retry-pause 5 --threads $threads --url http://bdfl.funtoo.org:9327 --userpass funtoo.public:p done
Make it executable:
# chmod +x go.sh
Run go.sh to start the miner. The cpuminer will only use idle CPU and will not slow down your system. Modern systems will generate somewhere from 15 to 60 KHash/sec total, which will result in $10 to Funtoo Linux per month for a Core i7 system at current exchange rates, when run continually.
Keep those miners running and thanks for supporting Funtoo Linux!
