I am following these instructions here to setup Geth on a Windows 10 system for running on the Rinkeby network.

In Step 3, there are two lines of code to run

geth --datadir=$HOME/.rinkeby init rinkeby.json
geth --networkid=4 --datadir=$HOME/.rinkeby --cache=512 --ethstats="yournode:Respect my authoritah!@stats.rinkeby.io" --bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa13b8c84684e1b4aab0cebea2ae45cb4d375b77eab56516d34bfbd3c1a833fc51296ff084b770b94fb9028c4d25ccf@ --rpc --rpcapi="personal,eth,network"

I ran the first line and it seems to be downloading the chain. What does the second line of code do? Do I run both lines at the same time??

  • New versions of geth (at least since v1.6.7) have the --rinkeby flag. So you only need to call geth --rinkeby <other_parameters> console – Ismael Sep 18 '17 at 18:50
  • @Ismael Something like geth --rinkeby --rpc --rpcapi="personal,eth,network,net,web3" --rpcport 8545 --rpcaddr I am trying to use truffle to deploy a contract using geth – Nyxynyx Sep 19 '17 at 7:31
  • Indeed that line works to launch rinkeby testnet. – Ismael Sep 19 '17 at 12:55

They are consecutive lines. The first essentially initializes the Rinkeby chain by downloading the parameter from the genesis file. The second actually starts the download of the chain.

  • After running the second line, how can you tell that the chain download is happening? The last line I see is INFO [09-18|11:56:25] HTTP endpoint opened:, then after some time INFO [09-18|11:58:58] Deduplicating database entries deduped=100000 – Nyxynyx Sep 18 '17 at 15:58
  • I have never seen the deduplicating database line, so can't help you there. It will be obvious when the chain download will start, as you will see plenty of log entries with the block number you are at, the number of blocks downloaded etc. If that doesn't happen make sure that you are not behind a firewall; you can also get more information by adding --verbosity=5 to the command line string, but be aware that it will generate lots of additional messages. – manuhalo Sep 18 '17 at 16:10
