Go-ethereum: Unable to attach

[dpisarewski]

System information

Geth version: 1.8.0-unstable-9d187f02
OS & Version: Windows

When I try to attach to the running local node, I get an unexpected error message:

PS C:\Users\mutexin> geth attach
Fatal: Unable to attach to remote geth: no known transport for URL scheme "c"
PS C:\Users\mutexin> geth attach --datadir "D:\Programs\Ethereum"
Fatal: Unable to attach to remote geth: no known transport for URL scheme "d"

I think you should:
geth attach http://host:port
or
geth attach /xxxx/geth.ipc
xxxx is your datadir path

I'm getting the same error in the stable release of Geth 1.8, but only on Windows. On MacOS everything seems to be fine.

[sarbogast]

Apparently on Windows we now have to specify the IPC path, and it was not necessary in Geth 1.7.3:
geth attach ipc:\\.\pipe\geth.ipc

[oragious]

geth attach ipc:\\.\pipe\geth.ipc

This solution works for Win10 and v1.8.0-stable

[sarbogast]

It does. But once again an undocumented change, and a discrepancy between Windows and other platforms. As an online instructor trying to keep my cours material up-to-date, these things are a PITA

[FrozenKiwi]

Quick Q - where do you find the IPC file? I'm running geth without installing it (just unzipped the folder)

[FrozenKiwi]

never mind - just run the command in the same folder as the other instance and it seems to work

[tomw1808]

Is that expected behavior or will that be reverted to auto-discover the pipe on windows? I couldn't find anything in the changelogs, did I miss it?

[paulvi]

BTW, within Git Bash (for Windows) it is also possible to connect as well as

./geth attach ipc:\\\\.\\pipe\\geth.ipc

but the console output is not colored.

Hi, specifying port worked for me. I had two nodes running in different ports and below attach command worked

geth attach http://localhost:8545
geth attach http://localhost:8547

[nukec]

confirmed geth attach ipc:\.\pipe\geth.ipc works for win env

@FirstBlockChain This is not Q&A, go to https://ethereum.stackexchange.com/
For a new bug report or on stackexchange , specify used version, and the way you launched.

At first glance, you may have missed \ before .
Seen
geth attach ipc:\.\pipe\geth.ipc

Should be
geth attach ipc:\\.\pipe\geth.ipc

[3esmit]

Can this be made by default in windows? geth attach ipc:\\.\pipe\geth.ipc

[uhuhh]

Same error with this conditions:

• Win7 @ x32
• mintty 2.8.5
  Only works with
  ./geth attach ipc:\\.\pipe\geth.ipc

can you give me 2 enthereum in the testnet..it's hard to get them ..my wallet address is：0x341453f0026b436b6f506626f74191e2461bbe16

[davoodmood]

how can i find my ipc path on windows?

[karalabe]

It always was geth attach ipc:\\.\pipe\geth.ipc, never a plain path. @davoodmood use the one mentioned previously. Geth also prints the path on startup.

[gumb0]

@karalabe Why not make it default on windows?

[karalabe]

Hmmm, it isn't? Then it should definitely be changed.

[Rbchi]

when we use : geth attach ipc:\.\pipe\geth.ipc ,we need to keep our startnode.cmd or geth --networkid 123 --dev --datadir data1 --rpc --rpcaddr 192.168.1.5 --rpc port 8545 --port 30303 running.

Apparently on Windows we now have to specify the IPC path, and it was not necessary in Geth 1.7.3:
geth attach ipc:\\.\pipe\geth.ipc

This is not working for me on Windows 10, Geth version 1.8.17-stable-8bbe7207. I get the error "Fatal: Unable to attach to remote geth: Timed out waiting for pipe '\.\pipe\geth.ipc' to come available"

[Hanafubuki]

After a long time I found out how to solve this.

First initialize your geth like this (if you want to use rinkeby):
geth --rinkeby --rpc --rpcapi="personal,eth,network,web3,net" --ipcpath "\.\pipe\geth.ipc"

And then open the console with the command:
geth attach ipc:\.\pipe\geth.ipc

still not helping

[KobbyRainworth]

Tried all the above but got "unable to attach to remote geth: Access is denied."
What else can i do about this?
