I would like to create a private network for test. And I would like to connect to this private network from commandline client or Ethereum wallet/mint.
I have created a private network as below.
geth --datadir=./chaindata init genesis.json
The content of genesis.json is genesis.json
Afterwards, I have started private network with following commands. (I have tried both of these commands seperately)
geth --datadir=./chaindata
geth --datadir=./chaindata --networkid 15
Afterwards, I have opened another terminal and try to connect running private network. But it does not connect.
geth attach
I have realised it is trying to connect default geth.ipc which is not running and I have send the running private network's geth.ipc as parameter and I is solved.
geth attach ~/chaindata/geth.ipc
But, I could not change the default geth.ipc for Mist or Ethereum Wallet. How can I connect Ethereum Wallet/Mist to private network?
Ethereum Wallet/Mist error message during startup
Couldn't connect to node? See the logs for more:

to start a local test network you can now use
once you do, take note of where it has actually created it by reading the line:
Then to have MIST connect to the private network type this in your terminal (MAC version)
