When I try to run the daemon (compiled on Linux from the GitHub link in OP), I get:
************************
EXCEPTION: NSt8ios_base7failureE
CDataStream::read() : end of data
transfer in AppInit()
terminate called after throwing an instance of 'std::ios_base::failure'
what(): CDataStream::read() : end of data
and it crashes. Has anyone experienced anything similar, or has a fix?
Check to make sure its created a data folder named ".transfer" if it has, then i'm going to guess the last time you can the client was using sudo or root. and trying to start the file without sudo or root, after you've already used it will result in an error.
Try using "sudo transferd"
