@keitaj, I'm new to the Ethereum but answer I've found here has helped me. I'm working on my private network, I guess you too.

In short: change chainId param in your _genesis.json_ (or whatever you've called it). And don't forget to reinit geth nodes.

I have this to attempting to truffle migrate to Ropsten. How can I set genesis.json?

@damirka
Thanks! I solved this.
I modified chainId on genesis.json. I changed chainId to the same value as --networkid 11.

```genesis.json

{
"config": {
"chainId": 11,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"alloc" : {},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x20000",
"extraData" : "",
"gasLimit" : "0x2fefd8",
"nonce" : "0x0000000000000042",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
}

$ geth --datadir ~/data_testnet init ~/data_testnet/genesis.json
$ geth --networkid 11 --nodiscover --maxpeers 0 --datadir ~/data_testnet console 2>> ~/data_testnet/geth.log

personal.unlockAccount(eth.accounts[0])
true
eth.sendTransaction({from: eth.accounts[0], to: eth.accounts[1], value: web3.toWei("0.1", "ether")})
"0x178d40ffeeaa30bbab397d038b1a88a91639ad0c57abdb5b19b63b1ae5dc83f4"
