[Ethereum] Unable to attach to remote geth: Invalid pipe address ‘/.rinkeby/geth.ipc’

go-ethereummyetherwalletprivate-blockchainrinkebytestnets

I'm on Windows and trying to connect to Ethereum Testnet via rinkeby.

I downloaded geth 1.8.2 and Ethereum Wallet 0.9.3

I gave 1st command as:

geth –rinkeby –fast –cache=1024

NOTE: after above command, I get the url on cmd as:

url=\\\\.\\pipe\\geth.ipc

And 2nd command in another command prompt as:

geth –datadir=./rinkeby attach

The same commands were working earlier.

I uninstalled both geth and Ethereum wallet and installed latest versions. I tried the commands on the earlier versions also where they were working but now they are not.

I also tried connecting to Private net just now, but got the error message on 2nd command prompt as:

Unable to attach to remote geth: no known transport for URL scheme "c"

Thanks in advance!

I am sure about testnetwork. But this below solution is easy go for private network. And it's working fine.

While running the geth node itself, specify the ipcpath. It will open the geth node, ipc and javascript console for you in single window. Try the below command.

geth --datadir ../../private-network/node1 \
      --networkid 2061 \(it should be same, if you are running multiple nodes)
      --port 30304 \ (should be different for every nodes)
      --nodiscover \
      --rpc \
      --rpcaddr 127.0.0.1 \
      --rpcport 8504 \ (should be different for every nodes)
      --ipcpath ../../private-network/node1/geth.ipc \
      --mine --minerthreads 1 --gasprice "10000" \
      --etherbase 0xf628e41f3ca68341e9857102d4b3040aa418d763 \ (your coinbase account address)
      --verbosity 3 console

One example for the given script.

geth --datadir=D:/Blockchain_Tech/node1 --networkid 2061 --port 30305 --nodiscover --rpc --rpcaddr 127.0.0.1 --rpcport 8505 --ipcpath=D:/Blockchain_Tech/node1/geth.ipc --mine --minerthreads 1 --gasprice "10000" --etherbase 0x58ef18d5667552b4c0524b9a78cbf9493d2bd74a --verbosity 3 console

Note:- This script is for MS-Windows.

[Ethereum] Cannot attach to geth node running inside container

$ docker exec -it ethereum-node /geth attach ipc://root/.ethereum/devchain/geth.ipc

Try to use this command if it works. Maybe you should change geth.ipc path in the command.

The answer you are linking to is pretty old, and a lot of things will have changed since then in the ecosystem.

DevMode seems to be very strict. See source code here: https://github.com/ethereum/go-ethereum/blob/master/cmd/utils/flags.go, in particular the following lines:

Starting at line 798:

if ctx.GlobalBool(DevModeFlag.Name) {
    // --dev mode can't use p2p networking.
    cfg.MaxPeers = 0
    cfg.ListenAddr = ":0"
    cfg.DiscoveryV5Addr = ":0"
    cfg.NoDiscovery = true
    cfg.DiscoveryV5 = false
}

At line 816:

switch {
    case ctx.GlobalIsSet(DataDirFlag.Name):
        cfg.DataDir = ctx.GlobalString(DataDirFlag.Name)
    case ctx.GlobalBool(DevModeFlag.Name):
        cfg.DataDir = filepath.Join(os.TempDir(), "ethereum_dev_mode")
    case ctx.GlobalBool(TestnetFlag.Name):
        cfg.DataDir = filepath.Join(node.DefaultDataDir(), "testnet")
    case ctx.GlobalBool(RinkebyFlag.Name):
        cfg.DataDir = filepath.Join(node.DefaultDataDir(), "rinkeby")
}

At line 991:

case ctx.GlobalBool(DevModeFlag.Name):
    cfg.Genesis = core.DevGenesisBlock()

Based on my reading of that source code, your attempts to set a datadir would all have been overridden. Also I don't fully understand the purpose of not allowing any peers, etc, but it seems that DevMode is pretty restrictive in its networking and is geared towards geth developers, not towards developers who want to build Dapps using geth.

For your purposes, you might find something like this to be more straightforward (apologies for pimping a post of mine): https://alanbuxton.wordpress.com/2017/07/19/first-steps-with-ethereum-private-networks-and-smart-contracts-on-ubuntu-16-04/
