I'm new to Ethereum so I am doing a course on it to learn how to develop decentralized apps.

I have Geth 1.6.1 and Mist.

According to the course I created a directory 'chaindata', then when starting geth --datadir chaindata it gives me this output:

MacBook-Pro-van-Lise-Lotte:Ethereum Lise-Lotte$ geth --datadir chaindata

INFO [05-28|12:07:55] IPC endpoint opened: /Users/Lise-Lotte/Documents/Jairo/Ethereum/chaindata/geth.ipc

But the geth.ipc file is never created so I can not attach. I searched for similar answers but I couldn't find one that works.

Please help, I'm hoping to continue my course ;)

The .ipc file is created but in a non-default directory since you specified it with the --datadir option. If you want to attach another console to it, repeat the same option such as geth --datadir chaindata attach.

Alternatively you can specify the .ipc file's path as follows: geth --datadir chaindata --ipcpath another/directory.

  • Thanks, yes it says ipc endpoint is opened, but at the specified location, no geth.ipc is created. – Jairo Bambang Oetomo May 29 '17 at 14:21
  • The file only remains while Geth is running, and deleted when you stop it. Also it can be a hidden file. – jeff May 29 '17 at 14:57
