Go-ethereum: connection refused to Geth websocket / RPC ports

Created on 20 Mar 2018 · 5Comments · Source: ethereum/go-ethereum

Hi there,
I have installed Geth v.1.8.3-unstable on CentOS 7 / 64-bit with go version go1.8.3.

When trying to start geth with

$ nohup geth --datadir /home/bchain/Private_Chain/chaindata --mine --nodiscover --nat any --identity private chain --networkid 1900 --port 30301 --verbosity 5 --rpc --rpcaddr 0.0.0.0 --rpcport 8545 --rpccorsdomain '*' --rpcapi personal,admin,db,eth,net,web3,miner,shh,txpool,debug --ipcpath /home/bchain/Private_Chain/get.ipc --ipcapi admin,db,eth,debug,miner,net,shh,txpool,personal,web3 --ws --wsaddr 0.0.0.0 --wsport 8546 --wsorigins '*' --wsapi personal,admin,db,eth,net,web3,miner,shh,txpool,debug --maxpeers 25 --etherbase 0 --gasprice 0 --targetgaslimit 9999999

Geth seems to be running successfully without error messages.

then..

$ geth attach ws://127.0.0.1:8546
Fatal: Unable to attach to remote geth: dial tcp :80: getsockopt: connection refused

$ geth attach ws:localhost:8546
Fatal: Unable to attach to remote geth: dial tcp :80: getsockopt: connection refused

or .. when connecting to RPC:
$ geth attach http://127.0.0.1:8545_
Fatal: Failed to start the JavaScript console: api modules: Post http://127.0.0.1:8545: dial tcp 127.0.0.1:8545: getsockopt: connection refused

I try $ ncat --listen 127.0.0.1 8546 and $ ncat 127.0.0.1 8546 and it catches all messages
(I think I have no problem of firewall)

Any idea ?

Thank you. This solves my problems and here is for others the working command line:

nohup geth --datadir /home/bchain/Private_Chain/chaindata --mine --nodiscover --nat any --identity private_chain --networkid 1900 --port 30301 --verbosity 5 --ipcpath /home/bchain/Private_Chain/geth.ipc --rpc --rpcaddr 0.0.0.0 --rpcport 8545 --rpccorsdomain '*' --rpcapi personal,admin,db,eth,net,web3,miner,shh,txpool,debug --ws --wsaddr 0.0.0.0 --wsport 8546 --wsorigins '*' --wsapi personal,admin,db,eth,net,web3,miner,shh,txpool,debug --maxpeers 25 --etherbase 0 --gasprice 0 --targetgaslimit 9999999

A few issues:

--identity private chain is wrong, it should be --identitiy "private chain", otherwise it considers only private to be the value of the flag, and then chain is not a flag any more (doesn't start with --), so it stops interpreting flags (and never reaches the RPC ones).
ws:localhost:8546 is not a valid url, it should be ws://127.0.0.1:8546
http://127.0.0.1:8545_ is invalid, the port ends in an underscore

All in all make sure the flags are correct, you're main issue is there.
