Connecting wallet to custom test network

Question

I want to connect my EthereumWallet app up to my private network, I fire up the app but it is trying to connect to the default test network. I get the error

Node type: geth
Network: test
Platform: darwin (Architecure x64)

What am I missing here to get my wallet connecting to my custom test network? Here is my local setup -

CustomGenesis.json

{
  "config": {
    "chainId": 15,
    "homesteadBlock": 0,
    "eip155Block": 0,
    "eip158Block": 0
  },
  "nonce": "0x000000000000002a",
  "difficulty": "0x20000",
  "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "author": "0x0000000000000000000000000000000000000000",
  "timestamp": "0x00",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "extraData": "0x",
  "gasLimit": "0x2fefd8",
  "alloc": {}
}

Then I'm firing this up with

geth --rpc --networkid=39318 --maxpeers=0 --datadir=./datatest --ipcpath=./datatest/geth.ipc --mine --minerthreads 1 console CustomGenesis.json

This seems to work fine, I get a bunch of mining output

Answer 1

Solved it. For the time being at least the ipcpath looks to be hard coded in the EthereumWallet. There is a note in the read me about it but you have to set your ipc path to the DEFAULT path for your system.

e.g. on my mac that is - update --ipcpath=./datatest/geth.ipc to --ipcpath=~/Library/Ethereum/geth.ipc
