I recently tried getting back into developing on Ethereum and it seems that everything about my setup has changed in the last half a year. I used to just be able to download a wallet from https://github.com/ethereum/mist/releases , and be able to connect to the public testnet easily. Now even the installation guide for geth tells me how to run a private testnet, but not how to connect to the public one...

So, I got my Windows geth from https://geth.ethereum.org/downloads/ . I tried running geth.exe --testnet --rpc --rpcapi "personal", but it doesn't appear to be synching with anything like it used to.

How can I connect geth to a public testnet, synch with it, get some ether to play around with and be able to connect to everything through a json rpc connection?

  • This is just a bad timing I think. The public testnet morden with id 2 was just reset and ropsten with id 3 introduced. Clients may not be ready, yet, to support them native, however, you can migrate manually, see for example this thread, and for mist, and one more for windows. – Afr Dec 2 '16 at 13:57

    Be careful using RPC with the personal API: it can allow people to brute-force your accounts. IPC is better in most cases – Tjaden Hess Dec 4 '16 at 7:40
  • @TjadenHess Can you elaborate on this? As in, how would using RPC with the personal API allow people to brute force your accounts, assuming you were running the testnet? – valkn0t Jun 14 '17 at 23:36
