How to solo mine with many pcs?

[BerettaJon]

I currently have 4 pcs for mining. How can I point the miners to all work together as one solo mining effort. I am able to solo mine only on the machine that has the namecoin client installed (localhost). I tried pointing the miners of the other pcs to the local IP addy of the host machine, but I am getting Problems communication with BTCRPC. Help?

Problem solved. I needed to append these lines to my bitcoin.conf file

server=1
daemon=1
rpcport=8332
rpcallowip=192.168.1.*
