How to allow only local connections? I've started to implement my bitcoin client to learn the protocol and faced a problem to see debugging output. When I start bitcoind with -debug option, it start to print so many debug messages in such speed that i can't see whats wrong with my client implementation. How can I start the bitcoind program in such way that it will not sync and just listen to new connections from local machine?
Try

bitcoind -bind=127.0.0.1 -connect=127.0.0.1
