There is a bug (receiver window + large fragments) preventing the SFTP
transfer of files longer than about 32K in older versions of the example
programs. The transfer will simply block. The newest version which will be
available within the next few days contains a correction.

To solve the connection failure problem:
- - Have you given the correct address to sctpsftp, including the port number?
Example: 1.2.3.4:sftp or 1.2.3.4:69 (69 = port of SFTP).
- - What are the local adresses of client and server? Check the programs'
output whether or not these values are correctly omitted from the
configuration of your systems. Also try to set them manually using the
- -local=<Address> parameter.
