I am trying to use my account to deploy contracts. I used this to unlock my account :

$ web3.personal.unlockAccount(eth.accounts[0], "password")
$ web3.personal.unlockAccount(eth.accounts[0], "password", 1500000)

I have tried both of them and it still gives this error :

Running migration: 1_initial_migration.js
  Deploying Migrations...
  ... undefined
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: authentication needed: password or unlock

I dont understand why this error persists even after the account has been unlocked. I do have enough balance (even though thats not the error). I am deploying on a private node but I have performed enough mining to have created the initial DAG as well as have some safe blocks.

  • Is truffle connecting to your geth instance? Are there another instances of geth runnig? You can try to add your address in the from field of truffle.js. – Ismael Sep 2 '17 at 18:07
  • Yes, truffle is getting connected. I added an unknown account into the from field in truffle and it told me so. There are no other geth instances running and I am already using the from field. – kneelb4darth Sep 3 '17 at 5:15
  • Which version of geth are you using? Where are you executing unlockAccount from (it should be from geth console)? – Ismael Sep 4 '17 at 15:20

A quick fix would be to set your defaultAccount and etherbase account to eth.accounts[0].
You can do this by running the following commands in your geth console:

eth.defaultAccount = eth.accounts[0]
miner.setEtherbase(eth.accounts[0])

and then run

personal.unlockAccount(eth.accounts[0], "password")
