When I run this geth with the following parameters:

geth --rpc --rpcaddr "my ip" --rpcport 8545

I get an error like:

(anonymous): Line 1:13 Unexpected identifier (and 1 more errors)

Please help.

    Can you maybe give the full error log and the full command line you are running? Else this will be tough to figure out what's the actual problem.

  • Please provide a screen print or all the messages. Have your run just geth or have you run both geth and ethminer? Do you have a proxy trying to connect to geth? Because the proxy will send different commands from what ethminer sends. May 4 '16 at 14:17

Summary

@coreytaylor211 is trying to run a remote server with a geth instance, and connect to this geth instance from ethminers running from home.

The error message is generated from the following code:

./Godeps/_workspace/src/github.com/robertkrimen/otto/parser/error.go: return self.error(self.idx, "Unexpected identifier")

within one of the go-ethereum code dependencies. This code is a parser for JavaScript.

I suspect that there is an application (most likely his ethminers trying to connect to his geth instance via a proxy previously pointed to a mining pool, but now pointed to his new remote server geth instance).

Changing the default RPC port from 8545 to something else and connecting his ethminer to this new port seems to have the problem.



Details

In this answer, I'll provide you with the steps to set up a geth instance, whether on your external server or internally in your home network. We will use the standard communication between geth and your ethminers and if your geth instance is on an external server, your mining performance will not be optimal. I can help you to improve the performance but this will require additional software to be setup but get the basic geth and ethminers running first and then we can take the next step.

In this answer, I'll assume that your geth instance is running on a server with the IP 123.456.1.2 .

geth

On your geth server, run geth with the following parameters:

geth --rpc --rpcaddr 123.456.1.2 --rpcport 8545 console

If you get errors, please post the whole error message and the commands you use in a separate answer. (We can clean up this post afterwards).

ethminer

On your ethminer server, you should be able to connect ethminer with your geth instance using the following command (remember NO proxy to be used in this step):

ethminer -F http://123.456.1.2:8545

Again, if you get errors, please post the whole error message and the commands you use in a separate answer.

Please tell me whether this setup works. We can then take the next step.
