Why are these transactions not broadcast in my private network?

Question

There are 3 nodes in my development environment. I use eth.sendTransaction to post some transactions ,and it seems that the transactions are not broadcast to other nodes.

JSON-RPC Request is :

{"jsonrpc":"2.0",
"method":"eth_sendTransaction",
"params":[{
            "gas":"0xea60",
            "gasPrice":"0x384",
            "to": "0x3d30704a45c6fd56b187343f3b3d21c443c2cdc1",
            "from":"0x01b537e37dbf4c917152a6012364193d6cc02ca9",
            "data":"0xf8b2cb4f....daa71b88ff922d735a7"
          }],
"id":1}

How can I broadcast the transactions to the whole network?

Answer 1

By default, accounts are locked so you will need to unlock your account: See this Unlock an Account with geth answer

Do this one of 2 ways:

1. Through your geth console

geth --unlock --password

2. Through geth javascript console

personal.unlockAccount(address, "password")

Keep in mind that entering the password non-interactivly stores the password in plaintext in the console history. So, the first option is the better way.

Answer 2

You can set the unlock time as a 3rd parameter in personal.unlockAccount so you can keep it unlocked for a long time period. I think the default is 5 minutes.
