I tried running the commands from https://github.com/ethereum/go-ethereum/wiki/Private-network
CustomGenesis.json:
{
"config": {
"chainId": 15,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"difficulty": "200000000",
"gasLimit": "2100000",
"alloc": {
"0x9370855ace244dc18fba024988046dde0d9f8ad8": {
"balance": "1000000000000000000000"
}
}
}
To create a database that uses this genesis block, run the following command. This will import and set the canonical genesis block for your chain.
geth --datadir path/to/custom/data/folder init genesis.json
Future runs of geth on this data directory will use the genesis block you have defined.
geth --datadir path/to/custom/data/folder --networkid 15
So I run the above with
geth --rpc --datadir path/to/custom/data/folder --networkid 15

then in a new shell,
geth attach
geth attach
Fatal: Unable to attach to remote geth: dial unix /Users/quantum/Library/Ethereum/geth.ipc: connect: no such file or directory
so now I cannot connect to my test network.
