----------------------------------
Resolution: Fixed
Fix Version/s: 0.9.0
Assignee: Guillaume Nodet
Improved sftp new subsystem to support sftp v3.
Log a warning if the subsystem / command is not found.
Your problem is actually that the subsystem is not configured.
You need to enable it using the following code before starting the server:
{code}
sshd.setSubsystemFactories(Arrays.<NamedFactory<Command>>asList(new SftpSubsystem.Factory()));
{code}
