Hi Greg, Thanks for your advice. I think I'll just download all my files off the existing node and start the network from scratch again - this time with more nodes and a proper configuration.
Is there a command that can be used to grab all the files from a Tahoe-LAFS network? (or least a given directory?) I have.. quite a few files. I will use the FTP interface in the mean time, but it seems like the FTPd can be a bit flaky at times. Is there a more "proper" way to do this?
