I have installed everything on the vps but when i type this command it does not work.

./minerd --url stratum+tcp://server:port --userpass worker.name:password

What do I do and how does it know to reach my wallet address?

I think we see the problem spelled out in the judges ruling.  Private enterprise has seduced American's to willing give up privacy.  Every month Facebook slowly peels back the layers of privacy, just slow enough that their is no revolt.  The ACLU and Americans need to push to pass laws to make it illegal for private enterprise to profit off our private data, sure we may have to pay a monthly fee but at least billions of dollars won't be spent studying our data only to market to us.  The government is simply buying this data from private corporations that we have freely given our data too.  We are all scared of a microchip being implanted under our skin. Since we refused to accept this, the government helped Apple develop and push the smart phone into society.  If you think about it, we all are willing carring the microchip day to day religiously in the form of a smart phone.  It is basically a graphical user interface for databases that we type into and gets sent to commercial and government databases at the same time. 

We have been in business many years selling unique metal collectibles. 

We just now started accepting bitcoin as I see this becoming very popular and an accepted method of payment.

We plan to offer small silver novelty items soon.

Please let me know if my products would be a good fit.
