I set a private blockchain on Ethereum. Two nodes up and sync'ed as peers. Issue is it does not start mining.

miner.Start() Returns "null" - What can I do?

Have set eth.coinbase() return the a new account etc. So am not sure whats happening.

Try miner.start(1) from the geth console, the number in parenthesis is the number of threads. To stop type miner.stop()
