YOU MUST UNDERSTAND AND ACCEPT THAT RUNNING THE CPUSHARE SOFTWARE WILL
INCREASE YOUR ELECTRIC BILL, THAT IT WILL INCREASE THE UTILIZATION OF
YOUR NETWORK INDEFINITELY, THAT IT WILL POTENTIALLY AGE ALL YOUR
HARDWARE COMPONENTS MORE QUICKLY, THAT IT WILL SLOW DOWN YOUR COMPUTER

YOU MUST AGREE TO PAY FOR ALL ELECTRICITY COSTS, FOR ALL NETWORKING
COSTS AND FOR ALL HARDWARE PART REPLACEMENTS. THIS IS TRUE EVEN IF
YOU'RE NOT ACTIVELY EXECUTING A TRANSACTION. FOR EXAMPLE THE CPUSHARE
GLOBAL BENCHMARK WILL RUN ON THE SELLER COMPUTERS AT REGULAR INTERVALS
OF TIME, AND IT WILL GENERATE CPU, RAM AND NETWORK LOAD EVEN IF THE
SELL ORDER ISN'T EXECUTING A TRANSACTION YET.
THE REDISTRIBUTION TO THIRD PARTIES OF ANY CPUSHARE SELL ORDER OR OF ANY

SUCH THIRD PARTY. YOU ARE RECOMMENDED TO SHARE YOUR SELL ORDERS OR THE CPUSHARE
LIVE CD (WITH THE SELL ORDER HARDCODED INSIDE) ONLY WITH PEOPLE THAT YOU FULLY
TRUST BECAUSE THE STATISTICS OF YOUR ACCOUNT WILL BE AFFECTED BY THEIR ACTIONS,
SO THEY CAN POTENTIALLY REDUCE THE NUMBER OF BUYERS WILLING TO BID FOR YOUR CPU

CPUSHARE SELL ORDER OR ANY CPUSHARE LIVE CD ON THE INTERNET, YOU'RE RECOMMENDED
AT LEAST TO ASK THE THIRD PARTIES VISITING YOUR INTERNET SITE TO READ AND AGREE

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
CPUShare currently only works on the x86-64, ppc64 and x86 architectures.
ppc should work too but it's untested.
You need to run a kernel >= 2.6.12 if your object is to sell your CPU
resources and it must be compiled with CONFIG_SECCOMP=y (most distributions
ships it that way).
To verify that your kernel supports seccomp you can execute in this directory:
python seccomp_test.py
If you see "The malicious bytecode has been killed successfully by seccomp" and
later "The seccomp_test.py completed successfully, thank you for testing." you
made it and your kernel is working correctly.
To start the CPUShare client it's enough to run:
./CPUShare start
You have to save the file "order.cpu" in this directory before starting
CPUShare. The file "order.cpu" is the CPUShare order that you downloaded from
the www.cpushare.com website (in the "Orders" section of your account).
With x86-64 under Debian you may need to run CPUShare under a chrooted 32bit
environment, here the details:
https://alioth.debian.org/docman/view.php/30192/21/debian-amd64-howto.html
The chroot isn't needed with other x86-64 distributions thanks to /lib64.
To stop CPUShare, you can run:
./CPUShare stop
Simply adding something like this:
su - nobody -c "/var/lib/nobody/cpushare/CPUShare start"
to your /etc/init.d/boot.local might be enough to autostart CPUShare at boot.
Networking doesn't need to be up and running when you start it. You're not
forced to run "./CPUShare stop" while shutting down your computer.
Alternatively you can start it with cron (runing "CPUShare start" once CPUShare
is already running won't hurt).
If the CPUShare protocol will change and it will require an upgrade of the
client software, you will be notified by email and the client will quit
automatically printing a message in the logs.
You'll find all the CPUShare logs in the files cpushare-*.log in this
directory, please check them if something goes wrong and then send all the
bugreports to the cpushare-devel@cpushare.com mailing list (you don't need to
be subscribed to post there).
If you modify the sell client in a malicious way, your sell price will go down
and eventually your account will be freezed.
There is already a debian package available and other distributions may follow
to make it easier to install it.
Enjoy!
